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

    The Exchange is filing with the Commission a proposal to amend 
Exchange Rules 11.3(a)-(b) to define the term ``Sponsored Access'' and 
to codify that the agreement required by and between the Sponsoring 
Member and Sponsored Participant must include a provision that any 
Sponsored Access relationship must follow the requirements of SEC Rule 
15c3-5, the Market Access Rule (``MAR'').\5\ The text of the proposed 
rule change is provided in Exhibit 5 and is available on the Exchange's 
website at https://info.memxtrading.com/regulation/rules-and-filings/.\6\
---------------------------------------------------------------------------

    \5\ 17 CFR 240.15c3-5.
    \6\ The Exchange proposes to implement the proposed changes to 
Exchange Rules 11.3(a)-(b) on a date that will be announced via 
Regulatory Notice, notifying both existing and prospective 
Sponsoring Members and Sponsored Participants, of the new rule 
language and required contractual provisions.
---------------------------------------------------------------------------

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

[[Page 37937]]

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 those 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 the 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The purpose of this filing is to amend Exchange Rules 11.3(a)-(b) 
to define the term ``Sponsored Access'' and to codify that the 
agreement required by and between the Sponsoring Member and Sponsored 
Participant must include a provision that any Sponsored Access 
relationship must follow the requirements of the MAR.
Sponsored Access Definition
    Per current Exchange rules a Sponsored Participant \7\ may be a 
Member \8\ or non- Member of the Exchange whose direct electronic 
access to the Exchange is authorized by a Sponsoring Member \9\ 
pursuant to the requirements set forth in Exchange Rules 11.3(b)(1)-
(3). The Exchange proposes to amend Exchange Rule 11.3(a) to include 
the following definition, ``Sponsored Access shall mean an arrangement 
whereby a Member permits its Sponsored Participants to enter orders 
into the Exchange's System that bypass the Member's trading system and 
are routed directly to the Exchange, including through a service bureau 
or other third-party technology provider.'' The Exchange notes that the 
proposed definition of Sponsored Access is identical to that adopted 
\10\ by Cboe BZX Exchange, Inc. (``Cboe BZX'') and substantively 
identical to that adopted \11\ by The Nasdaq Stock Market LLC 
(``Nasdaq''). The Exchange believes defining Sponsored Access will 
provide Sponsoring Members with greater clarity in understanding which 
types of market access relationships \12\ are subject to Exchange Rules 
11.3(a)-(b) and what obligations Sponsoring Members and Sponsored 
Participants must satisfy when establishing a Sponsored Access 
relationship.
---------------------------------------------------------------------------

    \7\ The term ``Sponsored Participant'' means a person which has 
entered into a sponsorship arrangement with a Sponsoring Member 
pursuant to Rule 11.3. See Exchange Rule 1.5(dd).
    \8\ The term ``Member'' means any registered broker or dealer 
that has been admitted to membership in the Exchange. A Member will 
have the status of a ``member'' of the Exchange as that term is 
defined in Section 3(a)(3) of the Act. Membership may be granted to 
a sole proprietor, partnership, corporation, limited liability 
company or other organization which is a registered broker or dealer 
pursuant to Section 15 of the Act, and which has been approved by 
the Exchange. See Exchange Rule 1.5(p).
    \9\ The term ``Sponsoring Member'' shall mean a Member that is a 
registered broker-dealer and that has been designated by a Sponsored 
Participant to execute, clear and settle transactions from the 
System. The Sponsoring Member shall be either (i) a clearing firm 
with membership in a clearing agency registered with the Commission 
that maintains facilities through which transactions may be cleared 
or (ii) a correspondent firm with a clearing arrangement with any 
such clearing firm. See Exchange Rule 1.5(ee).
    \10\ See Securities and Exchange Act Release No. 34-97146) 
(March 15, 2023) 88 FR 17065 (March 21, 2023) (SR-CboeBZX-2023-015) 
(Notice of Filing and Immediate Effectiveness of a Proposed Rule 
Change To Amend Its Sponsored Participant Rules 11.3(a) and 
11.3(b)(2)); Cboe BZX Rule 11.3(a), available at: https://cdn.cboe.com/resources/regulation/rule_book/BZX_Exchange_Rulebook.pdf.
    \11\ See Securities and Exchange Act Release No. 34-76449) 
(November 27, 2015) 80 FR 73011 (November 23, 2015) (SR-NASDAQ-2015-
140) (Notice of Filing and Immediate Effectiveness of the Proposed 
Rule Change Relating to Sponsored Access); Nasdaq General Equity and 
Options Rule, General 2: General Provisions, Section 22(a), 
available at: https://listingcenter.nasdaq.com/rulebook/Nasdaq/rules.
    \12\ Consistent with the proposed definition, such relationships 
generally include where a broker-dealer allows its customer--such as 
a hedge fund, mutual fund, bank or insurance company, an Exchange 
registered market maker, an individual, or another broker-dealer--to 
use the broker-dealer's market participant identifier (``MPID'') or 
other mechanism or mnemonic to enter orders into the Exchange's 
System that bypass the Sponsoring Member's order handling system and 
are electronically routed directly to the Exchange by the Sponsored 
Participant, including through a service bureau or other third-party 
technology provider. For the avoidance of doubt, in a scenario where 
a Sponsored Participant is also an Exchange Member (e.g., where a 
Sponsored Member provides market access to an Exchange Member Market 
Maker), (i) the Sponsored Participant will be subject to all 
Exchange rules and regulations applicable to Members acting in their 
own capacity, whether the Sponsored Participant accesses the 
Exchange via their own Membership or via a Sponsored Access 
arrangement; and (ii) the Sponsoring Member will be responsible for 
the Sponsored Participant activity just as it would for any other 
non-Member Sponsored Participant under Rule 11.3(b), including 
compliance with the MAR requirements and for compliance with the 
applicable Member-related activity electronically routed to the 
Exchange via the Sponsored Access arrangement (e.g., the Sponsoring 
Member would be required to hold appointments and would be subject 
to applicable requirements as an Exchange Market Maker in the 
products for which the Sponsored Participant Market Maker is 
registered and routes orders/quotes via the Sponsored Access 
arrangement).
---------------------------------------------------------------------------

Market Access Rule
    The Exchange seeks to codify that the agreement currently required 
under Exchange Rule 11.3(b)(2), by and between the Sponsoring Member 
and Sponsored Participant, must include a provision that any Sponsored 
Access relationship must follow the requirements of the MAR. While 
Sponsoring Members have existing obligations under the MAR because they 
are providing market access to their Sponsored Participants, the 
Exchange believes the proposed amendment will help to reinforce such 
obligations. Sponsored Participants will now be required to 
contractually agree with their Sponsoring Members to follow the 
requirements of the MAR.
    The Exchange believes that the proposed addition of Exchange Rule 
11.3(b)(2)(J) will reinforce to Sponsoring Members that Sponsored 
Access relationships must comply with the SEC's MAR, as well as 
Exchange rules regarding the provision of market access. As noted 
above, such relationships generally include where a broker-dealer 
allows its customer to use the broker-dealer's MPID or other mechanism 
or mnemonic to enter orders into the Exchange's System that bypass the 
Sponsoring Member's order handling system and are electronically routed 
directly to the Exchange by the Sponsored Participant, including 
through a service bureau or other third-party technology provider.
    The Exchange notes further that the proposed addition of Exchange 
Rule 11.3(b)(2)(J) is non-substantive in nature for Sponsoring Members 
because as broker-dealers providing market access, Sponsoring Members 
are already required to comply with the MAR, as well as with existing 
Exchange rules regarding market access. Indeed, per the Exchange's 
current Sponsored Participant rules the Sponsoring Member is already 
responsible for all its Sponsored Participant's activity on the 
Exchange \13\ and is required to comply with the Exchange's Certificate 
of Incorporation, Exchange LLC Agreement, Rules and procedures.\14\ 
This includes compliance with Exchange Rule 2.2, which requires, among 
other things, compliance with the Act and the regulations thereunder, 
including the MAR.
---------------------------------------------------------------------------

    \13\ See Exchange Rule 11.3(b)(2)(B).
    \14\ See Exchange Rule 11.3(b)(2)(C).
---------------------------------------------------------------------------

    The proposed addition of Exchange Rule 11.3(b)(2)(J) is potentially 
substantive in nature to Sponsored Participants in that the proposed 
amendment adds a requirement to the agreement by and between the 
Sponsoring Member and Sponsored Participant, requiring the Sponsored 
Participant to contractually agree to follow the requirements of the 
MAR. Importantly, as part of their obligation to comply with Exchange 
Rules and

[[Page 37938]]

procedures, existing Sponsoring Members will be expected to amend any 
existing contractual arrangements with their Sponsored Participants to 
include the new contractual provision proposed by the Exchange.\15\ The 
Exchange notes that the contractual requirement under proposed Exchange 
Rule 11.3(b)(2)(J) is also included, with substantively identical 
language, in the rulebooks of Cboe BZX \16\ and Nasdaq.\17\
---------------------------------------------------------------------------

    \15\ The Exchange notes that in connection with this proposed 
change, the Exchange will also amend its Sponsored Access 
Application form. The amendments to this form will include the 
deletion of the requirement that a Sponsoring Member provide the 
Exchange with a copy of its policies and procedures addressing the 
MAR and a detailed description of how it will comply with the MAR, 
but will further clarify that Sponsoring Members and Sponsored 
Participants must satisfy their regulatory obligations arising from 
the Sponsored Access relationship, including compliance with the MAR 
and, where a Sponsored Participant is an Exchange registered Market 
Maker, compliance with the Market Maker obligations required by 
applicable Exchange rules.

General Provisions, Section 22(b)(ii)(A), available at: https://listingcenter.nasdaq.com/rulebook/Nasdaq/rules.
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the Act and the rules and regulations thereunder applicable to the 
Exchange and, in particular, the requirements of Section 6(b) of the 
Act.\18\ Specifically, the Exchange believes the proposed rule change 
is consistent with the Section 6(b)(5) \19\ requirements that the rules 
of an exchange be 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. 
Additionally, the Exchange believes the proposed rule change is 
consistent with the Section 6(b)(5) \20\ requirement that the rules of 
an exchange not be designed to permit unfair discrimination between 
customers, issuers, brokers, or dealers.

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

Defining Sponsored Access
    As noted above, the Exchange believes that defining Sponsored 
Access will provide Sponsoring Members with greater clarity as to which 
types of market access relationships \21\ are subject to Exchange Rules 
11.3(a)-(b) and what obligations Sponsoring Members and Sponsored 
Participants must satisfy when establishing a Sponsored Access 
relationship. As such, the proposed rule change is designed to prevent 
fraudulent and manipulative acts and practices and serves to promote 
just and equitable principles of trade.
---------------------------------------------------------------------------

    \21\ Supra note 12.
---------------------------------------------------------------------------

    The proposed change will also help to reduce confusion by codifying 
a definition for such activity on the Exchange that is consistent with 
other industry practices currently in place elsewhere. The Exchange 
further notes that the proposed Sponsored Access definition is 
reasonable and does not affect investor protection because the proposed 
change does not present any novel or unique issues, as the proposed 
Sponsored Access definition has previously been adopted by both Cboe 
BZX and Nasdaq.\22\
---------------------------------------------------------------------------

    \22\ Supra notes 10-11.
---------------------------------------------------------------------------

Market Access Rule
    As noted above, the proposed addition of Exchange Rule 
11.3(b)(2)(J) will reinforce to Sponsoring Members that Sponsored 
Access relationships must comply with the SEC's MAR, as well as 
Exchange Rules regarding the provision of market access. Also, by 
adding proposed Exchange Rule 11.3(b)(2)(J), Sponsored Participants are 
now required to contractually agree that their Sponsored Access to the 
Exchange must follow the requirements of the MAR.
    In this regard, the proposed amendment will help to ensure that by 
and between the Sponsoring Member and Sponsored Participant all orders 
entered onto the Exchange pursuant to a Sponsored Access relationship 
will follow the requirements of the MAR. As discussed, the Exchange 
believes the proposed addition of Exchange Rule 11.3(b)(2)(J) is non-
substantive in nature for Sponsoring Members because as broker-dealers 
providing market access, Sponsoring Members are already required to 
comply with the MAR, as well as with existing Exchange Rules regarding 
market access. The proposed addition of Exchange Rule 11.3(b)(2)(J) is 
potentially substantive in nature to Sponsored Participants in that the 
proposed amendment adds a new requirement to the relationship by and 
between the Sponsoring Member and Sponsored Participant, requiring the 
Sponsored Participant to contractually agree to follow the requirements 
of the MAR.
    The Exchange further notes that this aspect of the proposed rule 
change is reasonable and does not affect investor protection because 
the proposed change does not present any novel or unique issues, as the 
proposed contractual requirement also exists in the rulebooks of Cboe 
BZX and Nasdaq.\23\
---------------------------------------------------------------------------

    \23\ Supra notes 16-17.
---------------------------------------------------------------------------

    Accordingly, the proposed rule change will help to promote just and 
equitable principles of trade, remove impediments to and perfect the 
mechanism of a free and open market and national market system, and, in 
general to protect investors and the public interest.

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

    For the reasons noted below, the Exchange does not believe that the 
proposed rule change will impose any burden on competition that is not 
necessary or appropriate in furtherance of the purposes of the Act.
    The proposed Sponsored Access definition does not impose any burden 
on intramarket competition that is not necessary or appropriate in 
furtherance of the purposes of the Act. The proposed definition merely 
seeks to make clear to Sponsoring Members that Sponsored Access is a 
relationship subject to Exchange Rule 11.3(a)-(b). Moreover, Sponsored 
Access is a voluntary arrangement that a Sponsoring Member voluntarily 
elects to enter with its Sponsoring Participant. A Member is not 
required to become a Sponsoring Member, and in fact, may decline to 
enter such a relationship with its customers.
    Additionally, the Exchange does not believe that the proposed rule 
change will impose any burden on intermarket competition that is not 
necessary or appropriate in furtherance of the purposes of the Act. 
Notably, other exchanges have in place similar rules and documentation 
requirements applicable to sponsored participants and their sponsoring 
members.\24\ Moreover, as described above, the proposed Sponsored 
Access definition is identical to that adopted by Cboe BZX and 
substantively identical to that adopted by Nasdaq, and the proposed 
requirement for Sponsored Participants to contractually agree that 
their Sponsored Access to the Exchange must follow the requirements of 
the MAR also exists in the rulebooks of Cboe BZX and Nasdaq.
---------------------------------------------------------------------------

    \24\ Supra notes 10-11 and 16-17.
---------------------------------------------------------------------------

    The proposed rule change to explicitly cite the MAR in Exchange 
Rule 11.3(b)(2)(J) does not impose any

[[Page 37939]]

burden on intramarket competition that is not necessary or appropriate 
in furtherance of the purposes of the Act. As noted above, this change 
is non-substantive as Sponsoring Members are currently responsible for 
complying with the MAR with respect to their provision of Sponsored 
Access to Sponsored Participants. While the proposed addition of 
Exchange Rule 11.3(b)(2)(J) is potentially substantive in nature to 
Sponsored Participants because it requires a Sponsored Participant to 
contractually agree with its Sponsoring Member to follow the 
requirements of the MAR, the Exchange reiterates that the proposed 
contractual requirement also exists in the rulebooks of Cboe BZX and 
Nasdaq, and as such, should not raise any new or novel issues for 
consideration by Sponsored Participants.

C. Self-Regulatory Organization's Statement on Comments on the Proposed 
Rule Change Received From Members, Participants, or Others

    The Exchange neither solicited nor received comments on the 
proposed rule change.

III. Date of Effectiveness of the Proposed Rule Change and Timing for 
Commission Action

    The proposed rule change is filed for immediate effectiveness 
pursuant to Section 19(b)(3)(A) of Act \25\ and Rule 19b-4(f)(6) \26\ 
thereunder. The Exchange designates that the proposed rule change 
effects a change that (i) does not significantly affect the protection 
of investors or the public interest; (ii) does not impose any 
significant burden on competition; and (iii) by its terms, does not 
become operative for 30 days after the date of the filing, or such 
shorter time as the Commission may designate if consistent with the 
protection of investors and the public interest. Additionally, the 
Exchange has given the Commission written notice of its intent to file 
the proposed rule change, along with a brief description and text of 
the proposed rule change, at least five business days prior to the date 
of filing of the proposed rule change, or such shorter time as 
designated by the Commission.
---------------------------------------------------------------------------

    \25\ 15 U.S.C. 78s(b)(3)(A).
    \26\ 17 CFR 240.19b-4(f)(6).
---------------------------------------------------------------------------

    As noted above, the proposed Sponsored Access definition is 
intended only to provide additional clarity as to the type of market 
access subject to Exchange Rule 11.3(a)-(b). Moreover, as noted above, 
the proposed definition does not present any unique or novel issues, as 
it is identical in nature to the definition of Sponsored Access in the 
rulebooks of Cboe BZX and Nasdaq. In addition, the proposed MAR change 
is non-substantive in nature, as Sponsoring Members are already 
required to comply with the MAR. While the proposed addition of 
Exchange Rule 11.3(b)(2)(J) is potentially substantive in nature to 
Sponsored Participants because they must now contractually agree with 
the Sponsoring Member to follow the requirements of the MAR, as noted 
above, such requirement also exists in the rulebooks of Cboe BZX and 
Nasdaq, and, therefore, should not raise any new or novel issues for 
Sponsored Participants. Accordingly, the Exchange believes proposed 
Exchange Rule 11.3(b)(2)(J) will help to promote just and equitable 
principles of trade, remove impediments to and perfect the mechanism of 
a free and open market and national market system, and, in general to 
protect investors and the public interest.
    Furthermore, Rule 19b-4(f)(6)(iii) \27\ requires a self-regulatory 
organization to give the Commission written notice of its intent to 
file a proposed rule change under that subsection at least five 
business days prior to the date of filing, or such shorter time as 
designated by the Commission. The Exchange has provided such notice.
---------------------------------------------------------------------------

    \27\ 17 CFR 240.19b-4(f)(6)(iii).
---------------------------------------------------------------------------

    At any time within 60 days of the filing of the proposed rule 
change, the Commission summarily may temporarily suspend such rule 
change if it appears to the Commission that such action is necessary or 
appropriate in the public interest, for the protection of investors, or 
otherwise in furtherance of the purposes of the Act. If the Commission 
takes such action, the Commission will institute proceedings to 
determine whether the proposed rule change should be approved or 
disapproved.
