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

    The Exchange proposes to amend its Rules at Options 7, Section 9, 
Other Member Fees.\3\
---------------------------------------------------------------------------

    \3\ The Exchange initially filed the proposed pricing changes on 
November 28, 2023 (SR-Phlx-2023-52) to be effective on December 1, 
2023. On December 5, 2023, the Exchange withdrew SR-Phlx-2023-52 and 
replaced it with SR-Phlx-2023-56. On January 16, 2023, the Exchange 
withdrew SR-Phlx-2023-56 and submitted SR-Phlx-2024-02. On March 7, 
2024, the Exchange withdrew SR-Phlx-2024-02 and submitted this 
filing.
---------------------------------------------------------------------------

    The text of the proposed rule change is available on the Exchange's 
website at https://listingcenter.nasdaq.com/rulebook/phlx/rules, at the 
principal office of the Exchange, and at the Commission's Public 
Reference Room.

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 proposes to amend Options 7, Section 9, B, Port Fees, 
to increase the SQF Port \4\ Fee cap.
---------------------------------------------------------------------------

    \4\ ``Specialized Quote Feed'' or ``SQF'' is an interface that 
allows Lead Market Makers, Streaming Quote Traders (``SQTs'') and 
Remote Streaming Quote Traders (``RSQTs'') to connect, send, and 
receive messages related to quotes, Immediate-or-Cancel Orders, and 
auction responses into and from the Exchange. Features include the 
following: (1) options symbol directory messages (e.g., underlying 
and complex instruments); (2) system event messages (e.g., start of 
trading hours messages and start of opening); (3) trading action 
messages (e.g., halts and resumes); (4) execution messages; (5) 
quote messages; (6) Immediate-or-Cancel Order messages; (7) risk 
protection triggers and purge notifications; (8) opening imbalance 
messages; (9) auction notifications; and (10) auction responses. The 
SQF Purge Interface only receives and notifies of purge requests 
from the Lead Market Maker, SQT or RSQT. Lead Market Makers, SQTs 
and RSQTs may only enter interest into SQF in their assigned options 
series. Immediate-or-Cancel Orders entered into SQF are not subject 
to the Order Price Protection, the Market Order Spread Protection, 
or Size Limitation in Options 3, Section 15(a)(1), (a)(2) and 
(b)(2), respectively. See Options 3, Section 7(a)(i)(B).
---------------------------------------------------------------------------

    Today, Phlx assesses $1,250 per port, per month up to a maximum of 
$42,000 per month for an SQF Port that receives inbound quotes at any 
time within that month.\5\ Today, member organizations are not assessed 
an active SQF Port Fee for additional ports acquired for ten business 
days for the purpose of transitioning technology.\6\ The Exchange 
proposes to add the words ``active port'' in parenthesis at the end of 
the description of SQF Port Fee to tie the definition of an active port 
to the description for the port.\7\
---------------------------------------------------------------------------

    \5\ An active port shall mean that the port was utilized to 
submit a quote to the System during a given month. See Options 7, 
Section 9, B.
    \6\ The member organization is required to provide the Exchange 
with written notification of the transition and all additional 
ports, provided at no cost, will be removed at the end of the ten 
business days. See Options 7, Section 9, B.
    \7\ The Exchange also proposes a technical amendment to add a 
comma between ``per port'' and ``per month'' for the SQF Port Fee in 
Options 7, Section 9, B.
---------------------------------------------------------------------------

    At this time, the Exchange proposes to increase the maximum SQF 
Port Fee of $42,000 per month to $50,000 per month.\8\ The Exchange is 
not amending the $1,250 per port, per month fee. As is the case today, 
the Exchange would not assess a member organization an SQF Port Fee 
beyond the monthly cap once the member organization has exceeded the 
monthly cap for the respective month.
---------------------------------------------------------------------------

    \8\ Currently, 29% of Phlx Market Makers cap their SQF Port 
Fees. Of those Market Makers, there is a mix of small, medium and 
large Market Makers.
---------------------------------------------------------------------------

    Despite increasing the maximum SQF Port Fee from $42,000 per month 
to $50,000 per month, the Exchange will continue to offer member 
organizations the opportunity to cap their SQF Port Fees so that they 
would not be assessed these fees beyond the cap.
    Pursuant to Options 3, Section 7(a)(i)(B), Market Makers may only 
enter interest into SQF in their assigned options series. Pursuant to 
Options 3, Section 7(a)(i)(B), the SQF interface allows Market Makers 
to connect, send, and receive messages related to quotes, Immediate-or-
Cancel Orders, and auction responses to the Exchange. A Phlx Market 
Maker requires only one SQF Port to submit quotes in its assigned 
options series into Phlx. A Phlx Market Maker requires only one SQF 
Port to submit quotes in its assigned options series into Phlx. A Phlx 
Market Maker may submit all quotes through one SQF Port. While a Phlx 
Market Maker may elect to obtain multiple SQF Ports to organize its 
business,\9\ only one SQF Port is necessary for a Phlx Market Maker to 
fulfill its regulatory quoting obligations.\10\
---------------------------------------------------------------------------

    \9\ For example, a Phlx Market Maker may desire to utilize 
multiple SQF Ports for accounting purposes, to measure performance, 
for regulatory reasons or other determinations that are specific to 
that member organization.
    \10\ Phlx Market Makers have various regulatory requirements as 
provided for in Options 2, Section 4. Additionally, Phlx Market 
Makers have certain quoting requirements with respect to their 
assigned options series as provided in Options 2, Section 5. SQF 
Ports are the only quoting protocol available on Phlx and only 
Market Makers may utilize SQF Ports.
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act,\11\ in general, and furthers the objectives of 
Sections 6(b)(4) and 6(b)(5) of the Act,\12\ in particular, in that it

[[Page 21123]]

provides for the equitable allocation of reasonable dues, fees, and 
other charges among members and issuers and other persons using any 
facility, and is not designed to permit unfair discrimination between 
customers, issuers, brokers, or dealers.
---------------------------------------------------------------------------

    \11\ 15 U.S.C. 78f(b).
    \12\ 15 U.S.C. 78f(b)(4) and (5).
---------------------------------------------------------------------------

    The proposed pricing change to increase the maximum SQF Port Fee 
from $42,000 to $50,000 per month is reasonable because despite the 
increase in the maximum SQF Port Fee, the Exchange will continue to 
offer member organizations the opportunity to cap their SQF Port Fees 
so that they would not be assessed SQF Port Fees beyond the cap. 
Additionally, a Phlx Market Maker requires only one SQF Port to submit 
quotes in its assigned options series into Phlx. A Phlx Market Maker 
may submit all quotes through one SQF Port. While a Phlx Market Maker 
may elect to obtain multiple SQF Ports to organize its business,\13\ 
only one SQF Port is necessary for a Phlx Market Maker to fulfill its 
regulatory quoting obligations.\14\ Member organizations may choose a 
greater number of SQF Ports beyond one port, depending on that member 
organization's particular business model. Additionally, the Exchange 
believes that the caps are reasonable for two reasons.
---------------------------------------------------------------------------

    \13\ For example, a Phlx Market Maker may desire to utilize 
multiple SQF Ports for accounting purposes, to measure performance, 
for regulatory reasons or other determinations that are specific to 
that member organization.
    \14\ Phlx Market Makers have various regulatory requirements as 
provided for in Options 2, Section 4. Additionally, Phlx Market 
Makers have certain quoting requirements with respect to their 
assigned options series as provided in Options 2, Section 5. SQF 
Ports are the only quoting protocol available on Phlx and only 
Market Makers may utilize SQF Ports.
---------------------------------------------------------------------------

    First, SQF Ports are a secure method for Market Makers to submit 
quotes into the Exchange's match engine and for the Exchange to send 
messages related to those quotes to Market Makers. Phlx must manage the 
security and message traffic, among other things, for each port. 
Utilizing the cap to manage a Market Maker's costs while also managing 
the quantity of SQF Ports issued on Phlx has led the Exchange to select 
$50,000 as the amended monthly cap for SQF Ports. By capping the ports 
at a different level, the Exchange is considering the message traffic 
and message rates associated with the current number of outstanding 
ports and its ability to process messages. The ability to have a cap 
and amend that cap permits the Exchange to scale its needs with respect 
to processing messages in an efficient manner. The Exchange notes that 
Cboe Exchange, Inc. (``Cboe'') limits usage on each port and assesses 
fees for incremental usage.\15\
---------------------------------------------------------------------------

    \15\ Each Cboe Binary Order Entry (``BOE'') or FIX Logical Port 
incur the logical port fee indicated when used to enter up to 70,000 
orders per trading day per logical port as measured on average in a 
single month. For each incremental usage of up to 70,000 per day per 
logical port will incur an additional logical port fee of $800 per 
month. BOE or FIX Logical Ports provide users the ability to enter 
order/quotes. See Cboe's Fees Schedule.
---------------------------------------------------------------------------

    Second, the Exchange notes that multiple ports are not necessary, 
however, to the extent that some Market Makers elect to obtain multiple 
ports, the Exchange is offering to cap their total port cost at $50,000 
per month. Phlx believes the existence of a cap allows for efficiencies 
and permits Market Makers to increase their number of ports beyond the 
cap. The cap levels the playing field by allowing those Market Makers 
that want to obtain a larger number of ports to do so with the 
certainty of a fee cap. Without the cap, Phlx Market Makers may pay 
more to obtain multiple ports on Phlx. BOX Exchange LLC (``BOX'') 
assesses $1,000 per month for all SAIL Ports for Market Making and $500 
per month per port up to 5 ports for order entry and $150 per month for 
each additional port.\16\ Miami International Securities Exchange, 
LLC's (``MIAX'') MIAX Express Interface (``MEI'') Fee levels are based 
on a tiered fee structure based on the Market Maker's total monthly 
executed volume during the relevant month.\17\
---------------------------------------------------------------------------

    \16\ See BOX's Fee Schedule.
    \17\ MEI is a connection to MIAX systems that enables Market 
Makers to submit simple and complex electronic quotes to MIAX. MIAX 
caps its MEI Ports. For these Monthly MIAX MEI Fees levels, if the 
Market Maker's total monthly executed volume during the relevant 
month is less than 0.060% of the total monthly executed volume 
reported by OCC in the market maker account type for MIAX-listed 
option classes for that month, then the fee will be $14,500 instead 
of the fee otherwise applicable to such level. See MIAX's Fee 
Schedule.
---------------------------------------------------------------------------

    The number of ports that member organizations choose to purchase 
varies widely. Today, on Phlx, 2 Marker Makers have 1 SQF Port, 5 
Market Makers have 2-5 SQF Ports, 4 Market Makers have between 6-10 SQF 
Ports, and 11 Market Makers have more than 10 SQF Ports. Additionally, 
today, on Nasdaq GEMX, LLC no Market Makers have 1 SQF Port/SQF Purge 
Port, 1 Market Maker has 2-5 SQF Ports/SQF Purge Ports, 4 Market Makers 
have between 6-10 SQF Ports/SQF Purge Ports, and 8 Market Makers have 
more than 10 SQF Ports/SQF Purge Ports. Finally, on Nasdaq MRX LLC 
(``MRX''), 2 Marker Makers have 1 SQF Ports/SQF Purge Ports, no Market 
Makers have 2-5 SQF Ports/SQF Purge Ports, 2 Market Makers have between 
6-10 SQF Ports/SQF Purge Ports, and 6 Market Makers have more than 10 
SQF Ports/SQF Purge Ports.
    The proposed pricing change to increase the maximum SQF Port Fee 
from $42,000 to $50,000 per month is equitable and not unfairly 
discriminatory because the Exchange would uniformly not assess any 
Market Makers that exceeded the maximum SQF Port Fee any SQF Port Fees 
beyond the maximum amount. Market Makers are the only market 
participants that are assessed an SQF Port Fee because they are the 
only market participants that are permitted to quote on the Exchange. 
SQF Ports are only utilized in the Market Maker's assigned options 
series. The following chart represents the classification of Phlx 
members and the percentage of Market Makers.

[[Page 21124]]

[GRAPHIC] [TIFF OMITTED] TN26MR24.006

    Unlike other market participants, Market Makers are subject to 
market making and quoting obligations.\18\ These liquidity providers 
are critical market participants in that they are the only market 
participants that provide liquidity to Phlx on a continuous basis. In 
addition, the Exchange notes that Lead Market Makers are required to 
submit quotes in the Opening Process to open an options series.\19\ 
Market Makers are subject to a number of fees, unlike other market 
participants. Market Makers pay separate permit fees,\20\ and Streaming 
Quote Trader Fees,\21\ in addition to other fees paid by other market 
participants. Providing Market Makers a means to cap their cost related 
to quoting and enabling all Market Makers to acquire SQF Ports at no 
cost beyond a certain dollar amount enables these market participants 
to provide the necessary liquidity to Phlx at lower costs. Therefore, 
because Market Makers fulfill a unique role on the Exchange, are the 
only market participant required to submit quotes as part of their 
obligations to operate on the Exchange, and, in light of that role, 
they are eligible for certain incentives. The proposed SQF Port fee cap 
is designed to continue to incent Market Makers to quote on Phlx, 
thereby promoting liquidity, quote competition, and trading 
opportunities.
---------------------------------------------------------------------------

    \18\ See Options 2, Sections 4 and 5.
    \19\ See Options 3, Section 8.
    \20\ See Options 7, Section 8, A.
    \21\ See Options 7, Section 8, B.
---------------------------------------------------------------------------

    In 2022, NYSE Arca, Inc. (``NYSE Arca'') proposed to restructure 
fees relating to OTPs for Market Makers.\22\ In that rule change,\23\ 
NYSE Arca argued that,
---------------------------------------------------------------------------

    \22\ See Securities Exchange Act Release No. 95412 (June 23, 
2022), 87 FR 38786 (June 29, 2022) (SR-NYSEArca-2022-36). NYSE Arca 
proposed to increase both the monthly fee per Market Maker OTP and 
the number of issues covered by each additional OTP because, among 
other reasons, the number of issues traded on the Exchange has 
increased significantly in recent years.
    \23\ Id at 38788.

    Market Makers serve a unique and important function on the 
Exchange (and other options exchanges) given the quote-driven nature 
of options markets. Because options exchanges rely on actively 
quoting Market Makers to facilitate a robust marketplace that 
attracts order flow, options exchanges must attract and retain 
Market Makers, including by setting competitive Market Maker permit 
fees. Stated otherwise, changes to Market Maker permit fees can have 
a direct effect on the ability of an exchange to compete for order 
flow. The Exchange also believes that the number of options 
exchanges on which Market Makers can effect option transactions also 
ensures competition in the marketplace and constrains the ability of 
exchanges to charge supracompetitive fees for access to its market 
---------------------------------------------------------------------------
by Market Makers.

    Further, NYSE ARCA noted that,\24\
---------------------------------------------------------------------------

    \24\ Id at 38790.

    The Exchange further believes that its ability to set Market 
Maker permit fees is constrained by competitive forces based on the 
fact that Market Makers can, and have, chosen to terminate their 
status as a Market Maker if they deem Market Maker permit fees to be 
unreasonable or excessive. Specifically, the Exchange notes that a 
BOX participant modified its access to BOX in connection with the 
implementation of a proposed change to BOX's Market Maker permit 
fees. The Exchange has also observed that another options exchange 
group experienced decreases in market share following its proposed 
modifications of its access fees (including Market Maker trading 
permit fees), suggesting that market participants (including Market 
Makers) are sensitive to changes in exchanges' access fees and may 
respond by shifting their order flow elsewhere if they deem the fees 
to be unreasonable or excessive.
    There is no requirement, regulatory or otherwise, that any 
Market Maker connect to and access any (or all of) the available 
options exchanges. The Exchange also is not aware of any reason why 
a Market Maker could not cease being a permit holder in response to 
unreasonable price increases. The Exchange does not assess any 
termination fee for a Market Maker to drop its OTP, nor is the 
Exchange aware of any other costs that would be incurred by a Market 
Maker to do so.

    The Exchange likewise believes that its ability to cap SQF Ports 
fees is constrained by competitive forces and that its proposed 
modifications to the SQF Port Fee cap is reasonably designed in 
consideration of the competitive environment in which the Exchange 
operates, by balancing the value of the enhanced benefits available to 
Market Makers due to the current level of activity on the Exchange with 
a fee structure that will continue to incent Market Makers to support 
increased liquidity, quote competition, and trading opportunities on 
the Exchange, for the benefit of all market participants.

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

    The Exchange does not believe that the proposed rule change will 
impose any burden on competition not

[[Page 21125]]

necessary or appropriate in furtherance of the purposes of the Act.
Intermarket Competition
    The proposal does not impose an undue burden on intermarket 
competition. The Exchange believes its proposal remains competitive 
with other options markets who also offer order entry protocols. The 
Exchange notes that it operates in a highly competitive market in which 
market participants can readily favor competing venues if they deem fee 
levels at a particular venue to be excessive. The chart below shows the 
February 2024 market share for multiply listed options by exchange. Of 
the 17 operating options exchanges, none currently has more than a 
17.6% market share. Customers widely distribute their transactions 
across exchanges according to their business needs and the ability of 
each exchange to meet those needs through technology, liquidity and 
functionality.
[GRAPHIC] [TIFF OMITTED] TN26MR24.007

    Market share is the percentage of volume on a particular exchange 
relative to the total volume across all exchanges, and indicates the 
amount of order flow directed to that exchange. High levels of market 
share enhance the value of trading and ports.
    In such an environment, the Exchange must continually adjust its 
fees to remain competitive with other exchanges. Because competitors 
are free to modify their own fees in response, and because market 
participants may readily adjust their order routing practices, the 
Exchange believes that the degree to which fee changes in this market 
may impose any burden on competition is extremely limited.
    Other exchanges amended certain costs attributed to Market 
Makers.\25\ In 2022, MRX proposed a monthly cap for SQF Ports and SQF 
Purge Ports of 17,500.\26\ MRX noted in its rule change that, ``Only 
one SQF quote protocol is required for an MRX Market Maker to submit 
quotes into MRX and to meet its regulatory requirements.'' \27\
---------------------------------------------------------------------------

    \25\ See Securities Exchange Act Release No. 95412 (June 23, 
2022), 87 FR 38786 (June 29, 2022) (SR-NYSEArca-2022-36).
    \26\ See Securities Exchange Act No. 96824 (February 7, 2023), 
88 FR 8975 (February 10, 2023) (SR-MRX-2023-05) (Notice of Filing 
and Immediate Effectiveness of Proposed Rule Change To Amend MRX 
Options 7, Section 6).

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

    If the Commission were to apply a different standard of review this 
proposal than it applied to other exchange fee filings, where Market 
Maker fees were increased and port fee caps were established, it would 
create a burden on competition such that it would impair Phlx's ability 
to compete among other options markets. Additionally, BOX assesses 
$1,000 per month for all SAIL Ports for Market Making and $500 per 
month per port up to 5 ports for order entry and $150 per month for 
each additional port.\28\ MIAX's MEI Fee levels are based on a tiered 
fee structure based on the Market Maker's total monthly executed volume 
during the relevant month.\29\
---------------------------------------------------------------------------

    \28\ See BOX's Fee Schedule.
    \29\ MEI is a connection to MIAX systems that enables Market 
Makers to submit simple and complex electronic quotes to MIAX. MIAX 
caps its MEI Ports. For these Monthly MIAX MEI Fees levels, if the 
Market Maker's total monthly executed volume during the relevant 
month is less than 0.060% of the total monthly executed volume 
reported by OCC in the market maker account type for MIAX-listed 
option classes for that month, then the fee will be $14,500 instead 
of the fee otherwise applicable to such level. See MIAX's Fee 
Schedule.
---------------------------------------------------------------------------

proposal than it applied to other exchange fee filings, where Market 
Maker fees were increased and port fee caps were established, it would 
create a burden on competition such that it would impair Phlx's ability 
to compete among other options markets.
Intramarket Competition
    The Exchange's proposed pricing change to increase the maximum SQF 
Port Fee from $42,000 to $50,000 per month does not impose an undue 
burden on competition because the Exchange would uniformly not assess 
any Market Makers that exceeded the maximum SQF Port Fee any SQF Port 
Fees beyond the maximum amount. Market Makers are the only market 
participants that are assessed an SQF Port Fee because they are the 
only

[[Page 21126]]

market participants that are permitted to quote on the Exchange. Unlike 
other market participants, Market Makers are subject to market making 
and quoting obligations.\30\ These liquidity providers are critical 
market participants in that they are the only market participants that 
provide liquidity to Phlx on a continuous basis. In addition, the 
Exchange notes that Lead Market Makers are required to submit quotes in 
the Opening Process to open an options series.\31\ Market Makers are 
subject to a number of fees, unlike other market participants. Market 
Makers pay separate permit fees,\32\ and Streaming Quote Trader 
Fees,\33\ in addition to other fees paid by other market participants. 
Providing Market Makers a means to cap their cost related to quoting 
and enabling all Market Makers to acquire SQF Ports at no cost beyond a 
certain dollar amount enables these market participants to provide the 
necessary liquidity to Phlx at lower costs. Therefore, because Market 
Makers fulfill a unique role on the Exchange, are the only market 
participant required to submit quotes as part of their obligations to 
operate on the Exchange, and, in light of that role, they are eligible 
for certain incentives. The proposed SQF Fee cap is designed to 
continue to incent Market Makers to quote on Phlx, thereby promoting 
liquidity, quote competition, and trading opportunities.
