(the ``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given 
that on June 18, 2025, MX2 LLC (``MEMX'' or the ``Exchange'') filed

I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    The Exchange is filing with the Commission a proposed rule change 
to adopt rules to govern the trading of options on the Exchange. The 
text of the proposed rule change is provided in Exhibit 5.

II. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the Exchange included statements 
concerning the purpose of and basis for the proposed rule change and 
discussed any comments it received on the proposed rule change. The 
text of these statements may be examined at the places specified in 
Item IV below. The Exchange has prepared summaries, set forth in 
sections A, B, and C below, of the most significant aspects of such 
statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The Exchange is proposing to adopt a series of rules in connection 
with MX2 Options, which will be a facility of the Exchange. MX2 Options 
will operate an electronic trading system developed to trade options 
(the ``System'') leveraging the Exchange's [sic] existing robust and 
resilient technology platform that it uses to operate MEMX Equities and 
MEMX Options. Much of the proposed functionality for MX2 Options is 
substantially similar to MEMX Options, thus, the Exchange proposes to 
adopt rules applicable to MX2 Options that are substantively identical 
or substantially similar to the approved rules of MEMX applicable to 
MEMX Options, with certain proposed changes or omissions that are 
described below.
    The System will provide for the electronic display and execution of 
orders, as described below. All Exchange Members will be eligible to 
participate in MX2 Options provided that the Exchange specifically 
authorizes them to trade in the System. The System will provide a 
routing service for orders when marketable trading interest is not 
present on MX2 Options and will comply with all applicable securities 
laws and regulations and the obligations of the

[[Page 29899]]

Options Order Protection and Locked/Crossed Market Plan.
MX2 Options Members
    Pursuant to the proposed rules in Chapter 17 (Participation on MX2 
Options), the Exchange will authorize any Exchange Member who meets 
certain enumerated qualification requirements (any such Member, an 
``Options Member'') and any Options Member's Sponsored Participants to 
obtain access to, and transact business on, MX2 Options.
    There will be two types of Options Members--Options Order Entry 
Firms (``OEFs'') and Options Market Makers. Options Market Makers, in 
turn, will be eligible to participate as Preferred Market Makers, Lead 
Market Makers and Market Makers. OEFs will be those Options Members 
representing orders as agent on MX2 Options or trading as principal on 
MX2 Options. Options Market Makers will be those Options Members 
registered with the Exchange as Options Market Makers pursuant to 
proposed Rule 22.2.
    To become an Options Market Maker, an Options Member is required to 
register by filing a written application with the Exchange, and then 
may select class appointments to make markets in those classes. 
Pursuant to proposed Rule 22.2, the Exchange may appoint one Lead 
Market Maker (or ``LMM'') per option class. Market Makers may select 
from among any option issues traded on the Exchange to request 
appointment as an LMM, subject to the approval of the Exchange. In 
considering the approval of the appointment of an LMM in each security, 
the Exchange will consider: the Market Maker's preference; the 
financial resources available to the Market Maker; the Market Maker's 
experience, expertise and past performance in making markets, including 
the Market Maker's performance in other securities; the Market Maker's 
operational capability; and the maintenance and enhancement of 
competition among Market Makers in each security in which they are 
registered, including pursuant to the performance standards set forth 
in proposed Rule 22.2(i).
    Pursuant to proposed Rule 22.2(c), an unlimited number of Market 
Makers may be registered in each class unless the number of Market 
Makers registered to make a market in a particular option class should 
be limited whenever, in the Exchange's judgment, quotation system 
capacity in an option class or classes is not sufficient to support 
additional Market Makers in such class or classes. The Exchange will 
not restrict access in any particular option class until such time as 
the Exchange has submitted objective standards for restricting access 
to the SEC for its review and approval.
    Options Market Makers will be required to electronically engage in 
a course of dealing reasonably calculated to contribute to the 
maintenance of fair and orderly markets. Among other things, an Options 
Market Maker would generally have to satisfy the following 
responsibilities and duties during trading: (1) maintain a continuous 
two-sided market in each of its appointed classes; (2) engage, to a 
reasonable degree under the existing circumstances, in dealings for its 
own accounts when there exists, or it is reasonably anticipated that 
there will exist, a lack of price continuity, a temporary disparity 
between the supply of (or demand for) a particular option contract, or 
a temporary distortion of the price relationships between option 
contracts of the same class; (3) compete with other Market Makers in 
its appointed classes; (4) enter a size of at least one contract for 
its best bid and its best offer; and (5) maintain minimum net capital 
in accordance with Commission and Exchange rules. The Exchange proposes 
to specify numerically the meaning of ``continuous'' with respect to 
maintaining continuous, two-sided quotes. For purposes of Rule 22.6, 
the Exchange will consider the continuous quoting requirement fulfilled 
if a Market Maker enters continuous bids and offers in 60% of the 
cumulative number of seconds, or such higher percentage as the Exchange 
may announce in advance, for which that Options Market Maker's 
appointed classes are open for trading, excluding any adjusted series, 
any intraday add-on series on the day during which such series are 
added for trading, any Quarterly Option Series, and any series with an 
expiration of greater than 270 days.\3\ Pursuant to proposed Rule 
22.5(c), substantial or continued failure by an Options Market Maker to 
meet any of its obligations and duties will subject the Options Market 
Maker to disciplinary action, suspension, or revocation of the Options 
Market Maker's registration as such or its appointment in one or more 
of its appointed options classes.
---------------------------------------------------------------------------

    \3\ The Exchange notes that it also proposes to adopt provisions 
that exclude from the calculation of continuous quoting those times 
that an Options Market Maker is experiencing a technical failure or 
limitation, during a trading halt, suspension or pause in the 
underlying security, or when the underlying security is in a limit 
up-limit down state. See, e.g., proposed Rule 22.6(d)(2)-(3).
---------------------------------------------------------------------------

    Options Market Makers receive certain benefits for carrying out 
their duties. For example, a Market Maker may be designated by the 
Exchange as a Lead Market Maker or may have orders directed to it in 
its capacity as a Preferred Market Maker, in each case receiving a 
priority advantage over other non-Customer orders to the extent 
applicable priority overlays have been implemented, as described below. 
In addition, a lender may extend credit to a broker-dealer without 
regard to the restrictions in Regulation T of the Board of Governors of 
the Federal Reserve System if the credit is to be used to finance the 
broker-dealer's activities as a specialist or market maker on a 
national securities exchange. Thus, an Options Market Maker has a 
corresponding obligation to hold itself out as willing to buy and sell 
options for its own account on a regular or continuous basis to justify 
this favorable treatment. The Exchange notes that the proposed 
continuous quoting requirement under proposed Rule 22.6(d) is 
substantially identical to that of MEMX Options as well as other 
options exchanges, including Cboe EDGX Options (``EDGX Options''), 
Nasdaq PHLX LLC (``Phlx''), and Nasdaq ISE, LLC (``ISE'').\4\
---------------------------------------------------------------------------

    \4\ See MEMX Rule 22.6(d); EDGX Options Rule 22.6(d); Phlx Rule 
1081(c) and ISE Rule 804(e).
---------------------------------------------------------------------------

    Pursuant to proposed Rule 17.2(f), every Options Member shall at 
all times maintain membership in another registered options exchange 
that is not registered solely under Section 6(g) of the Exchange Act 
\5\ or in FINRA. OEF's that transact business with Public Customers 
must at all times be members of FINRA. Pursuant to proposed Rule 
17.2(g), (Requirements for Options Participation, Options Principal), 
every Options Member will be required to have at least one registered 
Options Principal who satisfies the criteria of that rule, including 
the satisfaction of a proper qualification examination. An OEF may only 
transact business with Public Customers if such Options Member also is 
an Options Member of another registered national securities exchange or 
association with which the Exchange has entered into an agreement under 
Rule 17d-2 under the Exchange Act \6\ pursuant to which such other 
exchange or association shall be the designated options examining 
authority for the OEF. The proposed rules relating to qualification and 
participation on MX2 Options as an Options Member (including as an OEF 
and an Options Market Maker) are substantively identical to the 
relevant rules of MEMX Options.

    As provided in proposed Rule 16.2, existing Exchange Rules 
applicable to

[[Page 29900]]

the MX2 equities market contained in Chapters 1 through 15 of the 
Exchange Rules will apply to Options Members unless a specific Exchange 
Rule applicable to the MX2 Options market (proposed Chapters 16 through 
29 of the Exchange Rules) governs or unless the context otherwise 
requires. Options Members can therefore provide sponsored access to the 
MX2 Options Exchange to a non-Member (i.e., a Sponsored Participant) 
pursuant to Rule 11.3 of the Exchange Rules.

Sponsored Participant who is authorized to obtain access to the System 
pursuant to Rule 11.3 (Access).
Execution System
    The Exchange's options System will leverage the Exchange's current 
state-of-the-art technology, including its customer connectivity, 
messaging protocols, quotation and execution engine, order router, data 
feeds, and network infrastructure. This approach minimizes the 
technical effort required for existing Exchange Members to begin 
trading options on MX2 Options. As a result, MX2 Options will closely 
resemble the Exchange's affiliate, MEMX Options, but will differ in 
that MX2 Options will maintain a pro rata allocation model with 
execution priority dependent on the capacity of an order (e.g., 
Customer or non-Customer) as well as status as a Lead Market Maker or 
Preferred Market Maker, as applicable. The proposed model for MX2 
Options is similar to other options exchanges such as EDGX Options, 
NYSE American Options (``NYSE American'') and the MIAX Options Exchange 
(``MIAX''), which are sometimes referred to as ``classic'' exchanges.
    Like the Exchange's [sic] system for MEMX Equities and Options, all 
trading interest entered into the System will be automatically 
executable. Orders entered into the System will be displayed 
anonymously. Thus, the System will offer anonymous trading, however, 
options trades are not currently anonymous through settlement. 
Accordingly, as set forth in proposed Rule 21.10, aggregated and 
individual transaction reports produced by the System will indicate the 
details of a User's transactions, including the contra party's 
executing firm ID (``EFID''), capacity, and clearing firm account 
number.\8\ The Exchange will become an exchange member of the Options 
Clearing Corporation (``OCC''). The System will be linked to OCC for 
the Exchange to transmit locked-in trades for clearance and settlement.
---------------------------------------------------------------------------

    \8\ The Exchange shall also reveal a User's identity: (i) when a 
registered clearing agency ceases to act for a participant, or the 
User's clearing firm, and the registered clearing agency determines 
not to guarantee the settlement of the User's trades; and (ii) for 
regulatory purposes or to comply with an order of an arbitrator or 
court. See proposed Rule 21.10. The Exchange notes that proposed 
Rule 21.10 is identical to MEMX Rule 21.10.
---------------------------------------------------------------------------

    Hours of Operation. As stated in proposed Rule 21.2, the MX2 
Options System will begin accepting orders after 9:30 a.m. Eastern Time 
pursuant to the market opening procedures described in proposed Rule 
21.7.\9\ Orders and bids and offers shall be open and available until 
4:00 p.m. Eastern Time except for option contracts on Fund Shares, as 
defined in proposed Rule 19.3(i), option contracts on exchange-traded 
notes including Index-Linked Securities, as defined in proposed Rule 
19.3(l), and option contracts on broad-based indexes, as defined in 
proposed Rule 29.1(j), which may close as of 4:15 p.m. Eastern Time. 
The proposed hours of operation on MX2 Options are the same as on MEMX 
Options.
---------------------------------------------------------------------------

    \9\ Specifically, Rule 21.7(a) states that the System shall open 
options, other than index options, for trading after the System's 
observation after 9:30 a.m. Eastern Time of both: (i) the first 
transaction on the primary listing market in the security underlying 
the option, and (ii) the Limit Up-Limit Down price bands applicable 
to the security underlying the option as disseminated by the 
applicable Securities Information Processor (``SIP''). With respect 
to index options, the System shall open for trading after a time 
period (which the Exchange determines for all classes) following the 
System's observation after 9:30 a.m. Eastern Time of the first 
disseminated index value for the index underlying an index option.
---------------------------------------------------------------------------

    Units of Trading. As stated in proposed Rule 21.3, the unit of 
trading in each series of options traded on MX2 Options will be the 
unit of trading established for that series by the OCC pursuant to the 
rules of the OCC and the agreements of the Exchange with the OCC. The 
proposed determination of the unit of trading for a series of options 
traded on MX2 Options is the same as on MEMX Options pursuant to MEMX 
Rule 21.3.
    Minimum Quotation and Trading Increments. As stated in proposed 
Rule 21.5(a), the Exchange is proposing to apply the following 
quotation increments: (1) if the options series is trading at less than 
$3.00, five (5) cents; (2) if the options series is trading at $3.00 or 
higher, ten (10) cents; and (3) if the options series is trading 
pursuant to the Penny Interval Program one (1) cent if the options 
series is trading at less than $3.00, five (5) cents if the options 
series is trading at $3.00 or higher, unless for QQQ, SPY, or IWM where 
the minimum quoting increment will be one (1) cent for all series. In 
addition, as stated in proposed Rule 21.5(b), the Exchange is proposing 
that the minimum trading increment for options contracts traded on MX2 
Options will be one (1) cent for all series. The Exchange also proposes 
to offer trading of Mini Options, and that the minimum trading 
increment for Mini Options shall be the same as the minimum trading 
increment permitted for standard options on the same underlying 
security.\10\ Such proposed minimum quotation and trading increments 
are the same as on MEMX Options pursuant to MEMX Rules 21.5(a), (b) and 
(c).
---------------------------------------------------------------------------

    \10\ Per proposed Rule 21.5(c), the minimum trading increment 
for Mini Options shall be determined in accordance with 
Interpretations and Policies .07 to Rule 19.5.
---------------------------------------------------------------------------

    Penny Interval Program. As set forth in proposed Rule 21.5(d), the 
Exchange is proposing to adopt a Penny Interval Program that is 
substantially similar to the penny programs of other exchanges, 
including MEMX Options, which includes minimum quoting requirements for 
option classes listed under the Penny Interval Program. However, 
eligibility for inclusion in the Penny Interval Program will be limited 
to those classes already operating under penny programs of other 
options exchanges at the time MX2 Options is launched. The list of 
option classes included in the Penny Interval Program will be announced 
by the Exchange via circular distributed to Options Members and 
published by the Exchange on its website.
    Order Types and Handling Instructions. The System will make 
available to Users two Order Types (as defined in proposed Rule 
21.1(d))--Limit Orders and Market Orders--as well as various other 
instructions and modifiers that can be appended to such orders. The 
characteristics and functionality of each Order Type is substantially 
similar to what is currently approved for use on MEMX Equities, MEMX 
Options, and on other options exchanges, including EDGX Options, except 
where described below. The

[[Page 29903]]

Exchange notes that each of the proposed rules regarding the order 
types and order type instructions and modifiers is substantively 
identical to the applicable rule for a corresponding order type or 
order type instruction or modifier offered by MEMX Options with the 
exception of the proposed addition of Reserve Orders, which are not 
currently offered on MEMX Options. Proposed Rule 21.1(d) includes the 
following details with respect to Limit Orders and Market Orders:
     Limit Order. Limit Orders are orders (including bulk 
messages) to buy or sell an option at a specified price or better. A 
Limit Order is marketable when, for a Limit Order to buy, at the time 
it is entered into the System, the order is priced at the current 
inside offer or higher, or for a Limit Order to sell, at the time it is 
entered into the System, the order is priced at the current inside bid 
or lower.
     Market Order. Market Orders are orders to buy or sell at 
the best price available at the time of execution. Market Orders to buy 
or sell an option traded on MX2 Options will be rejected if they are 
received when the underlying security is subject to a ``Limit State'' 
or ``Straddle State'' as defined in the Plan to Address Extraordinary 
Market Volatility Pursuant to Rule 608 of Regulation NMS under the Act 
(the ``Limit Up-Limit Down Plan''). Bulk messages may not be Market 
Orders.
    The System will also make available to Users several additional 
instructions that can be designated on an order (``Handling 
Instructions''). A Handling Instruction applied to a bulk message 
applies to each bid and offer within that bulk message. The Handling 
Instructions available on MX2 Options are described in proposed Rule 
21.1(e) and will include the following:
     Book Only. Book Only is an instruction that an order is to 
be ranked and executed on the Exchange pursuant to proposed Rule 21.8 
(Order Display and Book Processing) or cancelled, as appropriate, 
without routing away to another options exchange. Users may designate 
bulk messages as Book Only as set forth in proposed Rule 21.1(l).
     Post Only. Post Only is an instruction that an order is to 
be ranked and executed on the Exchange pursuant to proposed Rule 21.8 
(Order Display and Book Processing) or cancelled, as appropriate, 
without routing away to another options exchange except that the order 
will not remove liquidity from the MX2 Options Book. The System cancels 
or rejects a bid (offer) designated as Post Only with a price that 
locks or crosses the Exchange's best offer (bid). A Market Order cannot 
be designated as Post Only. Users may designate bulk messages as Post 
Only as set forth in proposed Rule 21.1(l).
     Intermarket Sweep Order (``ISO''). ISOs are orders that 
shall have the meaning provided in proposed Rule 27.1, which relates to 
intermarket trading. Such orders may be executed at one or multiple 
price levels in the System without regard to Protected Quotations at 
other options exchanges (i.e., may trade through such quotations). The 
Exchange relies on the marking of an order as an ISO order when 
handling such order, and thus, it is the entering Options Member's 
responsibility, not the Exchange's responsibility, to comply with the 
requirements relating to ISOs. ISOs are not eligible for routing 
pursuant to proposed Rule 21.9. A Market Order cannot be designated as 
an Intermarket Sweep Order. Users may not designate bulk messages as 
ISOs.
     Reserve Orders. Reserve orders are limit orders that have 
both a portion of the quantity displayed (``Display Quantity'') and a 
reserve portion of the quantity (``Reserve Quantity'') not displayed. 
Both the Display Quantity and Reserve Quantity of the Reserve Order are 
available for potential execution against incoming orders. If the 
Display Quantity of a Reserve Order is fully executed, the System will, 
in accordance with the User's instruction, replenish the Display 
Quantity from the Reserve Quantity using either Random Replenishment or 
Fixed Replenishment, as directed by the User. Under either instruction, 
any order with a Reserve Quantity will be handled as a new order by the 
System and a new order identification number will be created each time 
a displayed quantity is replenished. The Exchange will obfuscate the 
unique order identification number on its data feeds for replenishment 
of an order with Reserve Quantity. If the remainder of an order is less 
than the replenishment amount, the Exchange will display the entire 
remainder of the order. A User must instruct the Exchange as to the 
quantity of the order to be initially displayed by the System (``Max 
Floor'') when entering an order with a Reserve Quantity, which is also 
used to determine the replenishment amount, as set forth below. Users 
may not designate bulk messages as Reserve Orders.
    With respect to the replenishment instructions, if a User 
designates Random Replenishment, the replenishment quantities for the 
order are randomly determined by the System within a replenishment 
range established by the user, (i.e., the range will be between the Max 
floor minus the replenishment value selected by the User and the Max 
Floor plus the replenishment value established by the User. Further, a 
User must select whether the Random Replenishment be immediate or to 
have the time interval of such replenishment randomly set by the 
Exchange. If the User selects a random time interval, the System will 
randomly replenish the User's displayed replenishment quantity at 
different time intervals ranging up to one (1) millisecond following 
each execution that triggers replenishment. The nondisplayed portion of 
an order subject to Random Replenishment will remain fully executable 
prior to the replenishment of a User's displayed quantity.
    If the User selects Fixed Replenishment, the System will replenish 
the Display Quantity of the order to the Max Floor designated by the 
User. As noted above, the Exchange does not currently offer Reserve 
Orders on MEMX Options, however, the definition and functionality of 
Reserve Orders as proposed in MX2 Rule 21.1(e)(4) are substantively 
identical to that in MX2 Rule 11.6(k), as well as MEMX Rule 11.6(k), as 
Reserve Orders are provided on MEMX Equities. The Exchange notes that 
although Reserve Orders are not currently available on MEMX Options, 
they are available on multiple competing options exchanges,\11\ and 
Reserve orders operate in the same manner on those exchanges, the only 
difference being that the Exchange offers the random time interval 
functionality as an option if Random Replenishment is selected.\12\
---------------------------------------------------------------------------

    \11\ See., e.g., EDGX Options Rule 21.1(d)(1) and Nasdaq GEMX 
Options 3, Section 7(g).
    \12\ The Exchange emphasizes that the random time interval 
functionality is currently offered on MEMX under Rule 11.6(k) and 
MX2 under Rule 11.6(k).
---------------------------------------------------------------------------

    Time-in-Force Designations. Users entering orders into the System 
may designate such orders to remain in force and available for display 
and/or potential execution for varying periods of time. Unless 
cancelled earlier, once these time periods expire, the order (or the 
unexecuted portion thereof) is returned to the entering party. A Time-
in-Force applied to a bulk message applies to each bid and offer within 
that bulk message. Unless otherwise specified in the Exchange Rules or 
the context indicates otherwise, the Exchange determines which of the 
following Times-in-Force are available on a class or system basis. The 
Time-in-Force designations available on MX2 Options are described in 
proposed Rule 21.1(g) and will include the following:

[[Page 29904]]

     Immediate Or Cancel (``IOC''). IOC means, for an order so 
designated, an order that is to be executed in whole or in part as soon 
as such order is received. The portion not so executed immediately on 
the Exchange or another options exchange is cancelled and is not posted 
to the MX2 Options Book. IOC orders that are not designated as Book 
Only and that cannot be executed in accordance with proposed Rule 21.8 
on the System when reaching the Exchange will be eligible for routing 
away pursuant to proposed Rule 21.9. Users may designate bulk messages 
as IOC.
     Day. Day means, for an order so designated, an order to 
buy or sell which, if not executed expires at market close. Users may 
designate bulk messages as Day.
    The Exchange notes that each of the proposed Time-in-Force 
designations available on MX2 Options is identical to the same Time-in-
Force designation available on MEMX Options.
    Member Match Trade Prevention Modifiers. As with MEMX Options, the 
Exchange will allow Users to use certain Match Trade Prevention 
(``MTP'') modifiers, which are described in proposed Rule 21.1(h). Any 
incoming order designated with an MTP modifier will be prevented from 
executing against a resting opposite side order also designated with an 
MTP modifier and originating from the same EFID, Exchange Member 
identifier, trading group identifier, or Exchange Sponsored Participant 
identifier. The Exchange will offer the following MTP modifiers: MTP 
Cancel Newest, described in proposed Rule 21.1(h)(1); MTP Cancel 
Oldest, described in proposed Rule 21.1(h)(2); and MTP Cancel Both, 
described in proposed Rule 21.1(h)(3).
    Re-Pricing Mechanism. The Exchange, like MEMX Options, proposes to 
offer a re-pricing mechanism to Users to comply with the order 
protection and trade through restrictions of the Options Order 
Protection and Locked/Crossed Market Plan. This re-pricing mechanism, 
described in proposed Rule 21.1(i), is referred to by the Exchange as 
Price Adjust and is identical to the Price Adjust mechanism offered by 
MEMX Options pursuant to MEMX Rule 21.1(i).
    EFIDs. As proposed in Rule 21.1(j), the term ``EFIDs'' means 
Executing Firm IDs and shall refer to what the System uses to identify 
the User and the clearing number for the execution of orders and quotes 
submitted to the System with that EFID. A User may obtain one or more 
EFIDs from the Exchange (in a form and manner determined by the 
Exchange). The Exchange assigns an EFID to its Users. Each EFID 
corresponds to a single User and a single clearing number of a Clearing 
Member with the Clearing Corporation. A User may obtain multiple EFIDs, 
which may be for the same or different clearing numbers. A User is able 
(in a form and manner determined by the Exchange) to designate which of 
its EFIDs may be used for each of its ports. If a User submits an order 
or quote through a port with an EFID not enabled for that port, the 
System cancels or rejects the order or quote. The Exchange notes that 
its proposed Rule 21.1(j) is identical to MEMX Rule 21.1(j).
    Ports and Bulk Messages. Proposed Rule 21.1(k) defines two types of 
ports: (1) a ``physical port,'' which provides a physical connection to 
the System and may provide access to multiple logical ports; and (2) a 
``logical port'' or ``application session,'' which provides Users with 
the ability within the System to accomplish a specific function through 
a connection, such as order entry, data receipt, or access to 
information. The Exchange notes that each of the proposed types of 
ports available on MX2 Options is identical to the same types of ports 
on MEMX Options. The Exchange also proposes to offer bulk message 
functionality through the same logical ports as Users submit other 
messages to the Exchange, as MEMX Options does. Finally, the Exchange 
proposes to adopt the same bulk message functionality as is offered by 
MEMX Options. The term ``bulk message'' is proposed to mean a bid or 
offer included in a single electronic message a User submits with a 
Market Maker Capacity to the Exchange in which the User may enter, 
modify, or cancel up to an Exchange-specified number of bids and offers 
(which number the Exchange will announce via Exchange notice or 
publicly available technical specifications). The System handles a bulk 
message in the same manner as it handles an order or quote, unless the 
Exchange Rules specify otherwise. Users may submit bulk messages 
through a logical port, subject to the following: bulk messages must 
contain a Time-in-Force of Day or IOC; a Market Maker with an 
appointment in a class must designate a bulk message for that class as 
Post Only or Book Only, and a non-appointed Market Maker must designate 
a bulk message for that class as Post Only; the System cancels or 
rejects a Post Only bulk message bid (offer) with a price that locks or 
crosses the Exchange best offer (bid) or ABO (ABB); the System executes 
a Book Only bulk message bid (offer) that locks or crosses the ABO 
(ABB) against offers (bids) resting in the Book at prices the same as 
or better than the ABO (ABB) and then cancels the unexecuted portion of 
that bid (offer).
    Cancel Back. The term ``Cancel Back'' is proposed to mean an 
instruction a User designates on an order (including bulk messages) to 
not be subject to the Price Adjust process pursuant to proposed Rule 
21.1(i). The System cancels or rejects an order with a Cancel Back 
instruction (immediately at the time the System receives the order or 
upon return to the System after being routed away) if displaying the 
order on the Book would create a violation of proposed Rule 27.3, or if 
the order cannot otherwise be executed or displayed in the Book at its 
limit price. The System executes a Book Only--Cancel Back order against 
resting orders. The proposed definition of Cancel Back in proposed Rule 
21.1(m) is identical to a Cancel Back Order defined in MEMX Rule 
21.1(m).
    Market Opening Procedures. As stated in proposed Rule 21.7, the 
System shall open options, other than index options, for trading after 
the System's observation after 9:30 a.m. Eastern Time of both: (1) the 
first transaction on the primary listing market in the security 
underlying the option, and (2) the Limit Up-Limit Down price bands 
applicable to the security underlying the option as disseminated by the 
applicable Securities Information Processor (``SIP''). With respect to 
index options, the System shall open for trading after a time period 
(which the Exchange determines for all classes) following the System's 
observation after 9:30 a.m. Eastern Time of the first disseminated 
index value for the index underlying an index option. Because the 
Exchange does not propose to adopt an opening cross or similar opening 
process, the opening trade that occurs on the Exchange will be a trade 
in the ordinary course of dealings on the Exchange. Accordingly, the 
System will ensure that the opening trade in an options series will not 
trade through a Protected Quotation at another options exchange, 
consistent with the general standard regarding trade throughs 
articulated in proposed Rule 21.6(e). The proposed market opening 
procedures are substantively identical to the market opening procedures 
for MEMX Options. Additionally, the Exchange proposes under Rule 
21.7(c) that it may delay the commencement of trading in any class of 
options in the interests of a fair and orderly market. As stated in 
proposed Rule 21.6(c), orders received prior to the opening of the 
System will be cancelled. The Exchange believes that it is appropriate 
to commence operations on MX2 Options with simplified

[[Page 29905]]

procedures for when the System is open for trading because for a 
successful opening process to function, an exchange needs a critical 
mass of liquidity from market participants in order to price and 
execute opening transactions. In turn, as a new options exchange, MX2 
Options does not know the amount of pre-opening interest it will have, 
and it will have to gain market share in order to accumulate such 
interest. MX2 Options will re-evaluate its opening procedures over time 
and may propose to add an opening process through a rule filing 
submitted to the Commission in the future.
    Order Display/Matching System. The System will be based upon 
functionality currently approved for use in the Exchange's equities and 
MEMX Options trading systems. Specifically, the System will allow Users 
to enter Market Orders and priced Limit Orders to buy and sell MX2 
Options-listed options. All orders (including bulk messages) will be 
designated for display (price and size) on an anonymous basis by the 
Exchange.
    Routing. Pursuant to proposed Rule 21.9, the MX2 Options Exchange 
will support orders that are designated to be routed to the National 
Best Bid and Offer (``NBBO'') as well as orders that will execute only 
within MX2 Options. Orders that are designated to execute at the NBBO 
will be routed to other options markets to be executed when the 
Exchange is not at the NBBO consistent with the Options Order 
Protection and Locked/Crossed Market Plan. Subject to the exceptions 
contained in proposed Rule 27.2(b), (Order Protection, Exceptions to 
Trade-Through Liability), the System will ensure that an order will not 
be executed at a price that trades through another options exchange. An 
order that is designated by an Options Member as routable will be 
routed in compliance with applicable trade-through restrictions. Any 
order entered with a price that would lock or cross a Protected 
Quotation that is not eligible for either routing or the price adjust 
process as defined in proposed Rule 21.1(i) will be cancelled. Bulk 
messages are not eligible for routing. These rules related to routing 
are substantively identical to those of MEMX Options.
    Pursuant to proposed Rule 21.9(d), MX2 Options shall route orders 
in options via MEMX Execution Services LLC (``MEMX Execution 
Services''), which serves as the Outbound Router of the Exchange, as 
defined in Rule 2.11. The function of the Outbound Router will be to 
route orders in options listed and open for trading on MX2 Options to 
other options exchanges pursuant to the proposed rules of MX2 Options 
solely on behalf of MX2 Options. The Outbound Router is subject to 
regulation as a facility of the Exchange, including the requirement to 
file proposed rule changes under Section 19 of the Act. Use of MEMX 
Execution Services or Routing Services (as defined below) to route 
orders to other market centers is optional. In the event the Exchange 
is not able to provide order routing services through its affiliated 
broker-dealer, the Exchange will route orders to other options 
exchanges in conjunction with one or more routing brokers that are not 
affiliated with the Exchange (``Routing Services'').\13\ Parties that 
do not desire to use MX2 Execution Services or other Routing Services 
provided by the Exchange must designate orders as not available for 
routing.\14\
---------------------------------------------------------------------------

    \13\ See proposed Rule 21.9(e).
    \14\ See proposed Rule 21.9(d).
---------------------------------------------------------------------------

    In connection with the proposed rules regarding routing to away 
options exchanges, proposed Rule 21.9(f) provides that MEMX Execution 
Services has, pursuant to Rule 15c3-5 under the Act,\15\ implemented 
certain tests designed to mitigate the financial and regulatory risks 
associated with providing the Exchange's Users with access to such away 
options exchanges. Pursuant to the policies and procedures developed by 
MEMX Execution Services to comply with Rule 15c3-5, if an order or 
series of orders are deemed to be erroneous or duplicative, would cause 
the entering User's credit exposure to exceed a preset credit 
threshold, or are non-compliant with applicable pre-trade regulatory 
requirements (as defined in Rule 15c3-5), MEMX Execution Services will 
reject such orders prior to routing and/or seek to cancel any orders 
that have been routed. This is consistent with the routing 
implementation of other options exchanges, and the Exchange notes that 
proposed Rule 21.9(f) is substantively identical to MEMX Rule 21.9(f).
---------------------------------------------------------------------------

    \15\ 17 CFR 240.15c3-5.
---------------------------------------------------------------------------

    Order Priority. Upon opening, trades on the Exchange will occur 
when a buy order and a sell order match on the Exchange's order book. 
The system shall execute trading interest within the System in price 
priority, meaning it will execute all trading interest at the best 
price level within the System before executing trading interest at the 
next best price. Pursuant to proposed Rule 21.8(c), after considering 
price priority, all orders are matched according to pro-rata priority 
according to size. In addition, Customer, Lead Market Maker and/or 
Preferred Market Maker priority overlays are also available at the 
Exchange's discretion on a class-by-class basis pursuant to proposed 
Rule 21.8(d). The Exchange will issue a notice to Options Members which 
will specify which classes of options are initially subject to these 
additional priority overlays and will provide such Options Members with 
reasonable advance notice of any changes to the application of such 
overlays.
    Specifically, (i) the Customer Overlay provides Customers with 
priority over all non-Customer interest at the same price, and if there 
are two or more Customer orders for the same options series at the same 
price, priority is afforded to the Customer orders in the sequence in 
which they were received by the System; \16\ (ii) the Preferred Market 
Maker overlay (which may only be in effect if the Customer Overlay is 
also in effect and shall only apply to any remaining balance after 
Priority Customer Orders have been satisfied provides the Preferred 
Market Maker with priority over other Market Makers for a certain 
percentage of contracts allocated at the same price (60% or 40% 
depending upon the number of other Market Makers at the NBBO); \17\ and 
(iii) the Lead Market Maker overlay (which may only be in effect if the 
Customer Overlay is also in effect and shall only apply to any 
remaining balance after Priority Customer Orders have been satisfied) 
provides Lead Market Makers with priority over other Market Makers for 
a certain percentage of contracts allocated at the same price (60% or 
40% depending upon the number of other Market Makers at the NBBO) \18\ 
and for small size orders.\19\
---------------------------------------------------------------------------

    \16\ See proposed Rule 21.8(d)(1).
    \17\ See proposed Rule 21.8(f)(1), which states: For each 
incoming order, if the PMM has a priority quote at the NBBO, its 
participation entitlement is equal to the greater of (i) the 
proportion of the total size at the best price represented by the 
size of its quote, or (ii) sixty percent (60%) of the contracts to 
be allocated if there is only one (1) other Market Maker quotation 
or non-Customer order at the NBBO and forty percent (40%) if there 
are two (2) or more other Market Maker quotes and/or non-Customer 
orders at the NBBO.
    \18\ See proposed Rule 21.8(g)(1), which states: For each 
incoming order, if the LMM has a priority quote at the NBBO, its 
participation entitlement is equal to the greater of (i) the 
proportion of the total size at the best price represented by the 
size of its quote, or (ii) sixty percent (60%) of the contracts to 
be allocated if there is only one (1) other Market Maker quotation 
or non-Customer order at the NBBO and forty percent (40%) if there 
are two (2) or more other Market Maker quotes and/or non-Customer 
orders at the NBBO.
    \19\ See proposed Rule 21.8(g)(2), which states: Small size 
orders will be allocated in full to the LMM if the LMM has a 
priority quote at the NBBO. The Exchange will review this provision 
quarterly and will maintain the small order size at a level that 
will not allow small size orders executed by LMMs to account for 
more than 40% of the volume executed on the Exchange. Small size 
orders are defined as incoming orders of five (5) or fewer 
contracts.

---------------------------------------------------------------------------

[[Page 29906]]

    After executions resulting from the Priority Overlays described 
above, Orders and Quotes within the System for the accounts of non-
Customers, including Professional Customers, have next priority. If 
there is more than one highest bid or more than one lowest offer in the 
Consolidated Book for the account of a non-Customer, then such bids or 
offers will be afforded priority on a ``size pro rata'' basis.\20\
---------------------------------------------------------------------------

    \20\ See proposed Rule 21.8(e).
---------------------------------------------------------------------------

    In allocating the participation entitlements set forth in proposed 
Rule 21.8(h) to the Preferred Market Maker and the Lead Market Maker, 
the following shall apply.\21\ In a class of options where both the 
Lead Market Maker and the Preferred Market Maker participation 
entitlements are in effect and an Options Member has directed an order 
to a Preferred Market Maker: (A) if the Preferred Market Maker's 
priority quote is at the NBBO, the Preferred Market Maker's 
participation entitlement will supersede the Lead Market Maker's 
participation entitlements for an order directed to such Preferred 
Market Maker; (B) if the Preferred Market Maker's priority quote is not 
at the NBBO, the Lead Market Maker's participation entitlement will 
apply to that order, provided the Lead Market Maker's priority quote is 
at the NBBO; (C) if an order is preferred to the Lead Market Maker 
(i.e. the Lead Market Maker is also the Preferred Market Maker), the 
Lead Market Maker receives the participation and/or small order 
entitlement, as applicable, provided the Lead Market Maker/Preferred 
Market Maker's priority quote is at the NBBO; and (D) neither the 
Preferred Market Maker's nor the Lead Market Maker's priority quote is 
at the NBBO then executed contracts will be allocated in accordance 
with the pro-rata allocation methodology as described in paragraphs 
21.8(c) and 21.8(e) without regard to any participation entitlement. If 
an incoming order has not been preferred to a Preferred Market Maker by 
an Options Member, however, then the Lead Market Maker's participation 
entitlement will apply to that order, provided the Primary Market 
Maker's priority quote is at the NBBO.\22\
---------------------------------------------------------------------------

    \21\ See proposed Rule 21.8(h)(1).
    \22\ See proposed Rule 21.8(h)(2).
---------------------------------------------------------------------------

    As proposed and as noted above, the participation entitlements of 
proposed Rule 21.8 shall not be in effect unless the Customer Overlay 
is also in effect and the participation entitlements shall only apply 
to any remaining balance after Customer orders have been satisfied.\23\
---------------------------------------------------------------------------

    \23\ See proposed Rule 21.8(h)(3).
---------------------------------------------------------------------------

    Pursuant to proposed Rule 21.8(h)(4), neither the Lead Market Maker 
nor the Preferred Market Maker may be allocated a total quantity 
greater than the quantity they are quoting at the execution price. If 
the Lead Market Maker's or the Preferred Market Maker's allocation of 
an order pursuant to its participation entitlement is greater than its 
pro-rata share of priority quotes at the best price at the time that 
the participation entitlement is granted, neither the Lead Market Maker 
nor the Preferred Market Maker shall receive any further allocation of 
that order.
    In establishing the counterparties to a particular trade, the 
participation entitlements must first be counted against the Lead 
Market Maker's highest priority bids and offers or the Preferred Market 
Maker's highest priority bids or offers.\24\
---------------------------------------------------------------------------

    \24\ See proposed Rule 21.8(h)(5).
---------------------------------------------------------------------------

    The proposed participation entitlements only apply to the 
allocation of executions among competing Market Maker priority quotes 
existing on the MX2 Options Book at the time the order is received by 
the Exchange. No market participant is allocated any portion of an 
execution unless it has an existing interest at the execution price. 
Moreover, no market participant can execute a greater number of 
contracts than is associated with its interest at a given price. 
Accordingly, the Lead Market Maker and the Preferred Market Maker 
participation entitlements contained in the proposed Rule are not 
guarantees.\25\
---------------------------------------------------------------------------

    \25\ See proposed Rule 21.8(h)(6).
---------------------------------------------------------------------------

    The Exchange believes that proposed Rule 21.8 governing priority on 
the Exchange is consistent with other options exchanges that have

    Data Feeds. The System will include proprietary data feeds which 
will display without attribution to Users' orders on both the bid and 
offer side of the market for price levels then within MX2 Options using 
the minimum price variation applicable to that security. These data 
feeds with include a depth of book quotation and execution feed, a top 
of book quotation and executions information feed, a DROP feed which 
offers information regarding the options trading activity of a specific 
User, and a historical options data feed.\27\
---------------------------------------------------------------------------

    \27\ See proposed Rule 21.15(b)(1)-(4).
---------------------------------------------------------------------------

    Risk Controls. The Exchange also proposes to offer to all Users of 
MX2 Options the ability to establish certain risk control parameters 
and limits that are intended to assist Users in managing their market 
risk. The proposed risk controls are set forth in proposed Rules 21.16 
and 21.17 and are identical to those offered by MEMX Options pursuant 
to MEMX Rules 21.16 and 21.17.\28\ The proposed risk controls are 
designed to offer Users protection from entering orders outside of 
certain size and price parameters, as well as certain standard or 
Exchange-established parameters based on order type and market 
conditions.
---------------------------------------------------------------------------

    \28\ See Securities Exchange Act Release No. 98730 (October 12, 
2023) 88 FR 71898 (October 18, 2023) (SR-MEMX-2023-28) and 
Securities Exchange Act Release No. 99700 (March 8, 2024) 89 FR 
18689 (March 14, 2024) (SR-MEMX-2024-09) for details regarding the 
risk controls.
---------------------------------------------------------------------------

    Under the proposed Risk Monitor Mechanism, Users may configure risk 
limits for various parameters, including number of contracts executed 
(``volume''), notional value of executions (``notional''), number of 
executions (``count''), number of contracts executed as a percentage of 
number of contracts outstanding within an Exchange-designated time 
period or during the trading day (``percentage''), and the number of 
times the limits on any of the foregoing parameters are reached (``risk 
trips''). The System will track each of the parameters within an 
underlying for an EFID (``underlying limit''), across all underlyings 
for an EFID (``EFID limit''), across all underlyings for a group of 
EFIDs (``EFID Group'') (``EFID Group limit''), and/or across a 
customized group of orders designated by the User (``Custom Group 
Limit''), over a User-established time period (``interval'') and on an 
absolute basis for a trading day (``absolute limits'').
    When the System determines that a specified parameter has reached 
the User-defined risk limit, depending on the User's instructions and 
the applicable limit that has been reached, the Risk Monitor Mechanism 
either: (1) cancels or rejects such User's orders or quotes in all 
series of the applicable underlying(s) and cancels or rejects any 
additional orders or quotes from the User in the applicable 
underlying(s) until the counting program resets; or (2) suspends all of 
a User's resting orders or quotes in all series of the applicable 
underlying(s) and cancels or rejects any additional orders or quotes 
from the User in the applicable underlying(s) until the Exchange is 
instructed to reinstate such bids and offers. A User may also engage 
the Risk Monitor

[[Page 29907]]

Mechanism to cancel resting bids and offers, as well as subsequent 
orders as set forth in proposed Rule 22.10 (``mass cancellation'') or 
to suspend all resting bids and offers until the Exchange is instructed 
to reinstate such bids and offers (``mass suspension'').
    In addition to the Risk Monitor Mechanism functionality described 
above, the Exchange also proposes to offer additional price protection 
mechanisms and risk controls that relate to certain standard or 
Exchange-established parameters based on order type and market 
conditions, which are described in proposed Rule 21.17, as well as 
additional controls applicable to options activity, described in Rule 
21.17, Interpretations and Policies .01. These controls include a 
Market Order NBBO Width Protection, Limit Order Fat Finger Check, Buy 
Order Put Check, Drill-Through Price Protection, Market Orders in No-
Bid (Offer) Series control, Bulk Message Fat Finger Check, and 
Rejection of Bulk Message Updates, controls related to the maximum 
dollar amount for a single order and maximum number of contracts for a 
single order, controls related to the order types or modifiers that can 
be utilized as well as orders when the market is crossed, controls to 
restrict the options classes for which a User may enter orders to test 
symbols only, controls prohibiting the entry of duplicative orders, 
controls restricting the overall rate of order entry, and credit 
controls measuring both gross and net exposure that warn when 
approached and, when breached, prevent submission of either all new 
orders or Market Orders only.\29\
---------------------------------------------------------------------------

---------------------------------------------------------------------------

    Proposed Rule 21.17, Interpretation and Policy .02 indicates that 
the Exchange will offer risk functionality that permits a user to: to 
(i) cancel all unexecuted orders and quotes in the MX2 Options Book, or 
(ii) block the entry of any new orders and quotes, or (iii) both cancel 
all unexecuted orders and quotes in the MX2 Options Book and block the 
entry of any new orders and quotes. In addition to (i), (ii), and 
(iii), the Exchange also offers (iv) risk functionality that 
automatically cancels a User's open orders and quotes to the extent the 
User loses its connection to the Exchange. Further, MX2 Options offers 
batch cancel functionality that permits a User to cancel any orders or 
quotes in any series of options by requesting the Exchange to affect 
such cancellation. A User initiating such a request may also request 
that the Exchange block new inbound orders in any series of options. 
The block will remain in effect until the User requests the Exchange 
remove the block. Finally, proposed Rule 21.17, Interpretation and 
Policy .03 indicates that the risk controls provided are meant to 
supplement, and not replace, the Member's or User's own internal 
systems, monitoring, and procedures related to risk management and are 
not designed for compliance with Rule 15c3-5 under the Exchange Act. 
Responsibility for compliance with all Exchange and SEC rules remains 
with the Member or User.\30\

    One Second Exposure Period. Proposed Rule 22.11 would prohibit 
Options Members from executing as principal on MX2 Options orders they 
represent as agent unless (i) agency orders are first exposed on MX2 
Options for at least one (1) second or (ii) the Options Member has been 
bidding or offering on MX2 Options for at least one (1) second prior to 
receiving an agency order that is executable against such bid or offer. 
As noted above, proposed Rule 22.11 would require Options Members to 
expose their customers' orders on the Exchange for at least one second 
under certain circumstances. During this one second exposure period, 
other Options Members will be able to enter orders to trade against the 
exposed order. In adopting a one-second order exposure period, the 
Exchange is proposing a requirement that is consistent with the Rules 
of other options exchanges, including MEMX Options. Thus, the exposure 
period will allow Options Members that are members of other options 
exchanges to comply with Rule 22.11 without programming separate time 
parameters into their systems for order entry or compliance purposes. 
The Exchange believes that market participants are sufficiently 
automated that a one second exposure period allows an adequate time for 
market participants to electronically respond to an order. Also, it is 
possible that market participants might wait until the end of the 
exposure period, no matter how long, before responding. Thus, the 
Exchange believes that any longer than one second would not further the 
protection of investors or market participants, but rather, would 
potentially increase market risk to investors and other market 
participants by creating a longer period of time for the exposed order 
to be subject to market risk.
    The technology for the Exchange's trading system for MX2 Options 
will be the same technology currently used for MEMX Options, and the 
Exchange has had ample experience with that trading system to believe 
that one second is an adequate exposure period.
Options Order Protection and Locked/Crossed Market Plan Rules
    The Exchange will participate in the Options Order Protection and 
Locked/Crossed Market Plan (the ``Plan'') and therefore will be 
required to comply with the obligations of Participants under the Plan. 
The Plan essentially applies the Regulation NMS price-protection 
provisions to the options markets. Similar to Regulation NMS, the Plan 
requires the Plan Participants to adopt rules ``reasonably designed to 
prevent Trade-Throughs'', while exempting ISOs from that prohibition. 
The Plan's definition of an ISO is essentially the same as under 
Regulation NMS. The remaining exceptions to the trade-through 
prohibition, discussed more specifically below, either track those 
under Regulation NMS or correspond to unique aspects of the options 
market, or both. The Exchange notes that the proposed rules in Chapter 
27 (Options Order Protection and Locked and Crossed Markets Rules) are 
identical to the rules of MEMX Options, and as such, the Exchange is 
proposing to incorporate Chapter 27 of MEMX's rulebook by reference 
into Chapter 27 of the MX2 Rulebook.\31\
---------------------------------------------------------------------------

    \31\ Specifically, the Exchange shall denote: ``The rules 
contained in MEMX Chapter 27, as such rules may be in effect from 
time to time, are hereby incorporated by reference into this 
Chapter. Members must comply with MEMX Chapter 27 as if such rules 
were part of the Rules. Unless the context dictates otherwise, the 
following terms, or any variations of these terms, from MEMX Chapter 
27 have the following meaning for purposes of this Chapter: 
``Exchange'' means ``MX2''; and ``Member'' (i.e., MEMX Member) means 
``Member (i.e., MX2 Member).'' The Exchange will copy this language 
into the additional MEMX chapters it is proposing to incorporate by 
reference into MX2's rulebook, each as further described below.
---------------------------------------------------------------------------

Securities Traded on MX2 Options
    General Listing Standards. The Exchange proposes to adopt listing 
standards for options traded on MX2 Options as described in Chapter 19 
(Securities Traded on MX2 Options), as well as for index options as 
described in Chapter 29 (Index Rules), which are identical to the 
approved rules of MEMX Options.\32\ The Exchange will join the Options 
Listings Procedures Plan and will list and trade options already listed 
on other options exchanges. The Exchange will gradually phase-in its 
trading of options, beginning with a selection of actively traded 
options. Given that these rules mirror MEMX completely, the Exchange is 
proposing to incorporate the rules of Chapter 19 and Chapter 29 by 
reference

[[Page 29908]]

into Chapter 19 and 29 of MX2's rulebook.
---------------------------------------------------------------------------

    \32\ See MEMX Rules, Chapters 19 and 29.
---------------------------------------------------------------------------

Conduct and Operational Rules for Options Members
    The Exchange proposes to adopt rules for MX2 Options that are 
substantively identical to the rules of MEMX Options regarding: 
exercises and deliveries as described in Chapter 18 (Business Conduct); 
Chapter 23 (Exercises and Deliveries); records, reports and audits as 
described in Chapter 24 (Records, Reports and Audits); doing business 
with the public as described in Chapter 26 (Doing Business With the 
Public); and margin as described in Chapter 28 (Margin Requirements). 
Given that these rules mirror MEMX completely, the Exchange is 
proposing to incorporate each of the above chapters by reference into 
Chapters 18, 23, 24, 26 and 28 of MX2's rulebook.\33\
---------------------------------------------------------------------------

    \33\ See MEMX Rules, Chapters 18, 23, 24, 26, and 28.
---------------------------------------------------------------------------

National Market System
    MX2 Options will operate as a full and equal participant in the 
national market system for options trading established under Section 
11A of the Exchange Act,\34\ just as its equities market participates 
today. MX2 Options will become a member of the Options Price Reporting 
Authority (``OPRA''), the Options Linkage Authority (``OLA''), the 
Options Regulatory Surveillance Authority (``ORSA''), and the Options 
Listing Procedures Plan (``OLPP'').
---------------------------------------------------------------------------

    \34\ 15 U.S.C. 78k-1.
---------------------------------------------------------------------------

    The Exchange expects to participate in those plans on the same 
terms currently applicable to current members of those plans. The 
Exchange has contacted the leadership of each options-related national 
market system plan to begin the membership process.
Regulation
    The Exchange will leverage many of the structures it established to 
operate a national securities exchange in compliance with Section 6 of 
the Exchange Act.\35\ As described in more detail below, there will be 
three elements of that regulation: (1) the Exchange will join the 
existing options industry agreements pursuant to Section 17(d) of the 
Exchange Act prior to commencing operations,\36\ as it did with respect 
to equities; (2) the Exchange's Regulatory Services Agreement with 
FINRA will be amended as necessary prior to commencing operations and 
will govern many aspects of the regulation and discipline of Members 
that participate in options trading, just as it does for equities 
regulation; and (3) the Exchange will perform options listing 
regulation, as well as authorize Options Members to trade on MX2 
Options, and conduct surveillance of options trading as it does today 
for equities.

    Section 17(d) of the Exchange Act and the related Exchange Act 
rules permit SROs to allocate certain regulatory responsibilities to 
avoid duplicative oversight and regulation. Under Exchange Act Rule 
17d-1,\37\ the SEC designates one SRO to be the Designated Examining 
Authority, or DEA, for each broker-dealer that is a member of more than 
one SRO. The DEA is responsible for the financial aspects of that 
broker-dealer's regulatory oversight. Because MX2 Options Members also 
must be members of at least one other SRO, the Exchange would generally 
not be designated as the DEA for any of its members.
---------------------------------------------------------------------------

    \37\ 17 CFR 240.17d-1.
---------------------------------------------------------------------------

    Exchange Act Rule 17d-2 \38\ permits SROs to file with the 
Commission plans under which the SROs allocate among each other the 
responsibility to receive regulatory reports from, and examine and 
enforce compliance with specified provisions of the Exchange Act and 
rules thereunder and SRO rules by, firms that are members of more than 
one SRO (``common members''). If such a plan is declared effective by 
the Commission, an SRO that is a party to the plan is relieved of 
regulatory responsibility as to any common member for whom 
responsibility is allocated under the plan to another SRO.
---------------------------------------------------------------------------

    \38\ 17 CFR 240.17d-2.
---------------------------------------------------------------------------

    All of the options exchanges, FINRA, and NYSE have entered into the 
Options Sales Practices Agreement, a Rule 17d-2 agreement, and the 
Exchange intends to join this agreement prior to the commencement of 
operations for MX2 Options. Under this Agreement, the examining SROs 
will examine firms that are common members of the Exchange and the 
particular examining SRO for compliance with certain provisions of the 
Exchange Act, certain of the rules and regulations adopted thereunder, 
certain examining SRO rules, and certain proposed MX2 Options rules. In 
addition, the proposed MX2 Options rules contemplate participation in 
this Agreement by requiring that any Options Member also be a member of 
at least one of the examining SROs. The Exchange also intends enter 
into and seek Commission approval of a bilateral Rule 17d-2 agreement 
with FINRA prior to commencing of operations for MX2 Options. 
Additionally, all of the options exchanges and FINRA have entered into 
the Options-Related Market Surveillance Agreement, a Rule 17d-2 
agreement, and the Exchange intends to join this agreement prior to the 
commencement of operations for MX2 Options.
    For those regulatory responsibilities that fall outside the scope 
of any Rule 17d-2 agreements, the Exchange will retain full regulatory 
responsibility under the Exchange Act. However, the Exchange has 
entered into a Regulatory Services Agreement with FINRA, pursuant to 
which FINRA personnel operate as agents for the Exchange in performing 
certain of these functions. The Exchange and FINRA will continue to 
operate under the Regulatory Services Agreement that is currently in 
place but with modifications as necessary to accommodate the expanded 
scope of the relationship. The necessary modifications will be 
implemented prior to the commencement of operations of MX2 Options. As 
is the case with the Exchange's equities market, the Exchange will 
supervise FINRA and continue to bear ultimate regulatory responsibility 
for the MX2 Options Exchange.
    Consistent with the Exchange's existing regulatory structure, the 
Exchange's Chief Regulatory Officer shall have general supervision of 
the regulatory operations of MX2 Options, including responsibility for 
overseeing the surveillance, examination, and enforcement functions and 
for administering all regulatory services agreements applicable to MX2 
Options. Similarly, the Exchange's existing Regulatory Oversight 
Committee will be responsible for overseeing the adequacy and 
effectiveness of Exchange's regulatory and self-regulatory organization 
responsibilities, including those applicable to MX2 Options.
    Finally, as it does with equities, the Exchange will perform 
automated surveillance of trading on MX2 Options for the purpose of 
maintaining a fair and orderly market at all times. As it does with its 
equities trading, the Exchange will monitor MX2 Options to identify 
unusual trading patterns and determine whether particular trading 
activity requires further regulatory investigation by FINRA.
    In addition, the Exchange will oversee the process for determining 
and implementing trade halts, identifying and responding to unusual 
market conditions, and administering the Exchange's process for 
identifying and remediating ``obvious errors'' by and among its Options 
Members. The proposed rules in Chapter 20 (Regulation of Trading on MX2 
Options)

[[Page 29909]]

regarding halts, unusual market conditions, extraordinary market 
volatility, obvious errors, audit trail, transfers of positions, and 
off-exchange RWA transfers are substantively identical to the approved 
rules of MEMX Options.
Minor Rule Violation Plan
    The Exchange's disciplinary rules, including Exchange Rules 
applicable to ``minor rule violations,'' are set forth in Chapter 8 of 
the Exchange's current Rules. Such disciplinary rules will apply to 
Options Members and their associated persons.
    The Commission approved the Exchange's Minor Rule Violation Plan 
(``MRVP'') in 2020.\39\ The Exchange's MRVP specifies those uncontested 
minor rule violations with sanctions not exceeding $2,500 that would 
not be subject to the provisions of Rule 19d-1(c)(1) under the Act \40\ 
requiring that an SRO promptly file notice with the Commission of any 
final disciplinary action taken with respect to any person or 
organization.\41\ The Exchange's MRVP includes the policies and 
procedures included in Exchange Rule 8.15 (Imposition of Fines for 
Minor Violation(s) of Rules) and in Exchange Rule 8.15, Interpretations 
and Policy .01.
---------------------------------------------------------------------------

    \39\ See Release No. 34-89836 (September 11, 2020), 85 FR 58081 
(September 17, 2020) (Order Declaring Effective a Minor Rule 
Violation Plan) (``MRVP Order'').
    \40\ 17 CFR 240.19d-1(c)(1).
    \41\ The Commission adopted amendments to paragraph (c) of Rule 
19d-1 to allow SROs to submit for Commission approval plans for the 
abbreviated reporting of minor disciplinary infractions. See Release 
No. 34-21013 (June 1, 1984), 49 FR 23828 (June 8, 1984). Any 
disciplinary action taken by an SRO against any person for violation 
of a rule of the SRO which has been designated as a minor rule 
violation pursuant to such a plan filed with and declared effective 
by the Commission will not be considered ``final'' for purposes of 
Section 19(d)(1) of the Act if the sanction imposed consists of a 
fine not exceeding $2,500 and the sanctioned person has not sought 
an adjudication, including a hearing, or otherwise exhausted his 
administrative remedies.
---------------------------------------------------------------------------

    The Exchange proposes to amend its MRVP and Exchange Rule 8.15, 
Interpretation and Policy .01 to include proposed Rule 25.3 (Penalty 
for Minor Rule Violations).\42\ The rules included in proposed Rule 
25.3 as appropriate for disposition under the Exchange's MRVP are: (a) 
position limit and exercise limit violations; (b) violations regarding 
the failure to accurately report position and account information; (c) 
Market Maker quoting obligations; (d) violations regarding expiring 
exercise declarations; (e) violations relating to the failure to 
respond to the Exchange's requests for the submission of trade data; 
and (f) violations relating to noncompliance with the Consolidated 
Audit Trail Compliance Rule requirements. The rules included in 
proposed Rule 25.3 are the same as the rules included in the MRVPs of 
MEMX Options and other options exchanges.\43\
---------------------------------------------------------------------------

    \42\ In its proposal to adopt the MRVP, the Exchange requested 
that, going forward, to the extent that there are any changes to the 
rules applicable to the Exchange's MRVP, the Exchange requests that 
the Commission deem such changes to be modifications to the 
Exchange's MRVP.
    \43\ See MEMX Rule 25.3. See also, EDGX Options Rule 25.3 and 
Cboe BZX Options (``BZX Options'') Rule 25.3.
---------------------------------------------------------------------------

    Upon implementation of this proposal, the Exchange will include the 
enumerated options trading rule violations in the Exchange's standard 
quarterly report of actions taken on minor rule violations under the 
MRVP. The quarterly report includes: the Exchange's internal file 
number for the case, the name of the individual and/or organization, 
the nature of the violation, the specific rule provision violated, the 
fine imposed, the number of times the rule violation has occurred, and 
the date of disposition. The Exchange's MRVP, as proposed to be 
amended, is consistent with Sections 6(b)(1), 6(b)(5) and 6(b)(6) of 
the Act, which require, in part, that an exchange have the capacity to 
enforce compliance with, and provide appropriate discipline for, 
violations of the rules of the Commission and of the exchange.\44\ In 
addition, because amended Rule 8.15 will offer procedural rights to a 
person sanctioned for a violation listed in proposed Rule 25.3, the 
Exchange will provide a fair procedure for the disciplining of members 
and associated persons, consistent with Section 6(b)(7) of the Act.\45\
---------------------------------------------------------------------------

    \44\ 15 U.S.C. 78f(b)(1), 78f(b)(5) and 78f(b)(6).
    \45\ 15 U.S.C. 78f(b)(7).
---------------------------------------------------------------------------

    This proposal to include the rules listed in proposed Rule 25.3 in 
the Exchange's MRVP is consistent with the public interest, the 
protection of investors, or otherwise in furtherance of the purposes of 
the Act, as required by Rule 19d-1(c)(2) under the Act,\46\ because it 
should strengthen the Exchange's ability to carry out its oversight and 
enforcement responsibilities as an SRO in cases where full disciplinary 
proceedings are unsuitable in view of the minor nature of the 
particular violation. In requesting the proposed change to the MRVP, 
the Exchange in no way minimizes the importance of compliance with 
Exchange Rules and all other rules subject to the imposition of fines 
under the MRVP. However, the MRVP provides a reasonable means of 
addressing rule violations that do not rise to the level of requiring 
formal disciplinary proceedings, while providing greater flexibility in 
handling certain violations. The Exchange will continue to conduct 
surveillance with due diligence and make a determination based on its 
findings, on a case-by-case basis, whether a fine of more or less than 
the recommended amount is appropriate for a violation under the MRVP or 
whether a violation requires a formal disciplinary action.

Section 36 Exemption Request
    The Exchange proposes to incorporate by reference as MX2 Options 
rules certain rules of the Cboe Exchange, Inc. (``Cboe''), the New York 
Stock Exchange (``NYSE''), FINRA, and as described above, its 
affiliated exchange, MEMX. Specifically, MX2 Options proposes to 
incorporate by reference the applicable rules of MEMX with respect to 
Chapter 18 (Business Conduct), Chapter 19 (Securities Traded on MX2 
Options), Chapter 23 (Exercises and Deliveries), Chapter 24 (Records, 
Reports and Audits), Chapter 26 (Doing Business with the Public), 
Chapter 27 (Options Order Protection and Locked and Crossed Markets 
Rules), Chapter 28 (Margin Requirements) and Chapter 29 (Index Rules); 
\47\ MX2 Options Rule 26.16 proposes to incorporate by reference the 
applicable rules of FINRA with respect to Communications with Public 
Customers; MX2 Options Rule 28.3 proposes to incorporate by reference 
initial and maintenance margin requirements of either Cboe or NYSE; MX2 
Options Rule 29.5 proposes to incorporate by reference the applicable 
rules of Cboe with respect to position limits for broad based index 
options; and MX2 Options Rule 29.7 proposes to incorporate by reference 
the applicable rules of Cboe with respect to position limits for 
Narrow-Based and Micro-Narrow Based Index Options traded on MX2 Options 
and also on Cboe.
---------------------------------------------------------------------------

    \47\ Each MEMX Chapter incorporated by reference into MX2's 
rules will have the same chapter numbers in MX2's rulebook.
---------------------------------------------------------------------------

    Thus, for certain MX2 Options rules, Exchange members will comply 
with a MX2 Options rule by complying with the MEMX, Cboe, NYSE, or 
FINRA rule referenced. Using its authority under Section 36 of the Act, 
the Commission has previously exempted certain SROs from the 
requirement to file proposed rule changes under Section 19(b) of the 
Act when incorporating another SRO's rules by reference.\48\ Each such 
exempt

[[Page 29910]]

SRO has agreed to be governed by the incorporated rules, as amended 
from time to time, but, has not been required to file a separate 
proposed rule change with the Commission each time the SRO whose rules 
are incorporated by reference seeks to modify its rules. In addition, 
each SRO incorporated by reference only regulatory rules (e.g., margin, 
suitability, arbitration), not trading rules, and incorporated by 
reference whole categories of rules (i.e., did not ``cherry-pick'' 
certain individual rules within a category). Last, each exempt SRO had 
reasonable procedures in place to provide written notice to its members 
each time a change is proposed to the incorporated rules of another SRO 
in order to provide its members with notice of a proposed rule change 
that affects their interests, so that they would have an opportunity to 
comment on it.

---------------------------------------------------------------------------

    In connection with this proposal, the Exchange respectfully 
requests, pursuant to Rule 240.0-12 under the Act,\49\ an exemption 
under Section 36 of the Act from the rule filing requirements of 
Section 19(b) of the Act for changes to those MX2 Options rules that 
are effected solely by virtue of a change to a cross-referenced MEMX, 
Cboe, NYSE, or FINRA rule. The Exchange proposes to incorporate by 
reference categories of rules (rather than individual rules within a 
category) that are not trading rules. The Exchange also agrees to 
provide written notice to Options Members prior to the launch of MX2 
Options of the specific MEMX, Cboe, NYSE, and FINRA rules that it will 
incorporate by reference. In addition, the Exchange will notify Options 
Members whenever MEMX, Cboe, NYSE, or FINRA proposes a change to a 
cross-referenced MEMX, Cboe, NYSE, or FINRA rule.\50\ For the foregoing 
reasons, the Exchange believes that its request for exemptive relief is 
consistent with prior requests for, and provision of, similar exemptive 
relief.
---------------------------------------------------------------------------

    \49\ 17 CFR 240.0-12.
    \50\ The Exchange will provide such notice through a posting on 
the same website location where the Exchange will post its own rule 
filings pursuant to Rule 19b-4(l) under Act, within the time frame 
required by that rule. The website posting will include a link to 
the location on the MEMX, Cboe, NYSE, or FINRA website where the 
proposed rule change is posted.
---------------------------------------------------------------------------

Amendments to Existing Exchange Rules
    In addition to the rules of MX2 Options proposed above, the 
Exchange proposes to amend certain of its existing Exchange Rules that 
currently apply to the Exchange's equities market in order to reflect 
the Exchange's proposed operation of MX2 Options.
    First, the Exchange proposes to amend paragraph (d) of 
Interpretations and Policies .01 to Rule 2.5 (Restrictions), which 
generally requires each Member to register at least two Principals with 
the Exchange subject to certain exceptions described therein, to 
provide that such paragraph (d) shall not apply to a Member that solely 
conducts business on the Exchange as an Options Member, however, 
Options Members must comply with the registration requirements set 
forth in proposed Rule 17.2(g). The Exchange notes that proposed Rule 
17.2(g), which provides that every Options Member shall have at least 
one Options Principal and sets forth the Exchange's Options Principal 
registration requirements, is identical to MEMX Rule 17.2(g). In 
connection with this proposed change, the Exchange also proposes to 
amend paragraph (i) of Interpretations and Policies .01 to Rule 2.5 to 
include Options Principal as a registration category and to set forth 
the Exchange's qualification requirements for an Options Principal, 
which are the same as those for an Options Principal on MEMX Options.
    The Exchange also proposes to modify Rule 2.11(a)(6), which states 
that MEMX Execution Services shall maintain an error account for the 
purpose of addressing positions that are the result of an execution or 
executions that are not clearly erroneous under Rule 11.15 and result 
from a technical or systems issue at MEMX Execution Services, the 
Exchange, a routing destination, or a non-affiliate third-party routing 
broker that affects one or more orders (``Error Positions''). The 
proposed change to Rule 2.11(a)(6) would add a reference to the 
comparable provision to that which governs review and resolution of 
clearly erroneous transactions (e.g., for equities, Rule 11.15) but for 
options transactions, namely Rule 20.6, which governs review and 
resolution of options transactions that may qualify as obvious errors.
    Lastly, the Exchange proposes to amend Interpretations and Policies 
.01 Rule 8.15 (Imposition of Fines for Minor Violation(s) of Rules), 
which contains the list of Exchange Rule violations and recommended 
fine schedule pursuant to Rule 8.15, to include a new paragraph (i) 
referencing proposed Rule 25.3 for the recommended fines for minor rule 
violations of the Exchange Rules appliable to MX2 Options, which the 
Exchange notes are the same as those of MEMX Options.
2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent 
with Section 6(b) of the Act \51\ in general, and furthers the 
objectives of Section 6(b)(5) of the Act \52\ in particular, in that it 
is designed to prevent fraudulent and manipulative acts and practices, 
to promote just and equitable principles of trade, to foster 
cooperation and coordination with persons engaged in regulating, 
clearing, settling, processing information with respect to, and 
facilitating transactions in securities, to remove impediments to and 
perfect the mechanism of a free and open market and a national market 
system, and, in general, to protect investors and the public interest; 
and is not designed to permit unfair discrimination between customers, 
issuers, brokers, or dealers.
---------------------------------------------------------------------------

    \51\ 15 U.S.C. 78f(b).
    \52\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    As described above, the fundamental premise of the proposal is that 
the Exchange will operate its options market much in a similar manner 
to its affiliated options exchange, MEMX Options, with the exception of 
the priority model and certain other limited differences. Those 
differences (i.e. pro-rata priority model and the addition of Reserve 
orders), are not novel and are offered by other options exchanges.\53\ 
Further, the proposed Reserve Orders on MX2 Options will operate in the 
same manner and have the same functionality as those currently offered 
on MEMX \54\ and that have been approved under the Rules of MX2.\55\ 
The Exchange believes MX2 Options will benefit individual investors, 
options trading firms, and the options market generally. The entry of 
an innovative, cost competitive market such as MX2 Options will promote 
competition, spurring existing exchanges to improve their own 
executions systems and reduce trading costs.

    \53\ See supra notes 11 and 26.
    \54\ See MEMX Rule 11.6(k).
    \55\ See Exchange Rule 11.6(k).
---------------------------------------------------------------------------

    The basis for a majority of the proposed rules of MX2 Options are 
the approved rules of MEMX Options, which have already been found 
consistent with the Exchange Act. Therefore, the Exchange does not 
believe that any of the proposed order types and order type 
functionality raise any new or novel issues that have not

[[Page 29911]]

been previously considered by the Commission.
    The Exchange further believes that the functionality that it 
proposes to offer is consistent with Section 6(b)(5) of the Act because 
the System is designed to be efficient and its operation transparent, 
thereby facilitating transactions in securities, removing impediments 
to and perfecting the mechanisms of a free and open national market 
system. As described above, the Exchange's proposed rules, including 
the proposed Order Types and Handling Instructions, opening procedures, 
routing services, and order matching process are designed to provide a 
simplified suite of conventional features and to comply with all 
applicable regulatory requirements, including the obligations of the 
Options Order Protection and Locked/Crossed Market Plan.
    The Exchange believes that the proposed rules of MX2 Options, as 
well as the proposed method of monitoring for compliance with and 
enforcing such rules is also consistent with the Exchange Act, 
particularly Sections 6(b)(1), 6(b)(5) and 6(b)(6) of the Exchange Act, 
which require, in part, that an exchange have the capacity to enforce 
compliance with, and provide appropriate discipline for, violations of 
the rules of the Commission and of the exchange. The Exchange has 
proposed to adopt rules necessary to regulate Options Members that are 
nearly identical to the approved rules of MEMX Options other options 
exchanges, as described above. The Exchange proposes to regulate 
activity on MX2 Options in the same way it regulates activity on MEMX 
Options, specifically through various Exchange specific functions, an 
RSA with FINRA, as well as participation in industry plans, including 
plans pursuant to Rule 17d-2 under the Exchange Act.

B. Self-Regulatory Organization's Statement on Burden on Competition

    The Exchange does not believe that the proposed rule change will 
result in any burden on competition that is not necessary or 
appropriate in furtherance of the purposes of the Act. The Exchange 
operates in an intensely competitive global marketplace for transaction 
services. Relying on its array of services and benefits, the Exchange 
competes for the privilege of providing market services to broker-
dealers. The Exchange's ability to compete in this environment is based 
in large part on the quality of its trading systems, the overall 
quality of its market and its attractiveness to the largest number of 
investors, as measured by speed, likelihood and cost of executions, as 
well as spreads, fairness, and transparency.
    The Exchange notes that most U.S. options exchanges are owned and 
operated by companies that operate more than one options exchange.\56\ 
The primary reason to operate multiple options exchanges, as is true 
with respect to the proposed launch of MX2 Options, is that it allows 
an exchange operator to offer multiple market models, including a 
price-time market and a pro rata market, often with Customer priority 
as a critical component of the latter. Accordingly, the proposed rule 
change is intended to enhance competition by allowing the Exchange to 
compete with existing options exchanges that operate models based on 
Customer priority and pro rata allocations.

    \56\ NYSE operates two options exchanges, NYSE American and NYSE 
Arca; Nasdaq operates six options exchanges, ISE, Phlx, Nasdaq 
Options Market (``NOM''), Nasdaq MRX (``MRX''), Nasdaq BX Options 
(``BX''), and Nasdaq GEMX (``GEMX''), Cboe operates four options 
exchanges, Cboe Options, C2 Options Exchange (``C2''), EDGX Options 
and BZX Options; and MIAX operates four options exchanges, MIAX, 
MIAX Pearl, MIAX Emerald, and MIAX Sapphire.
---------------------------------------------------------------------------

    The proposed rule change will reduce the overall trading costs and 
increase price competition, both pro-competitive developments, and will 
promote further initiative and innovation among market centers and 
market participants.
