SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-103581; File No. SR-Phlx-2025-31]


Self-Regulatory Organizations; Nasdaq PHLX LLC; Notice of Filing 
and Immediate Effectiveness of Proposed Rule Change Related to SQF 
Ports

July 29, 2025.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given that 
on July 22, 2025, Nasdaq PHLX LLC (``Phlx'' or ``Exchange'') filed with 
the Securities and Exchange Commission (``Commission'') the proposed 
rule change as described in Items I and II, below, which Items have 
been prepared by the Exchange. The Commission is publishing this notice 
to solicit comments on the proposed rule change from interested 
persons.
---------------------------------------------------------------------------

    \1\ 15 U.S.C. 78s(b)(1).
    \2\ 17 CFR 240.19b-4.
---------------------------------------------------------------------------

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

    The Exchange proposes to amend the Exchange's Pricing Schedule at 
Options 7, Section 9, B, Port Fees, to propose a limit to the number of 
Specialized Quote Feed (``SQF'') \3\ Ports a Market Maker \4\ may 
subscribe to in a month.
---------------------------------------------------------------------------

    \3\ ``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 Phlx Options 3, Section 7(a)(i)(B).
    \4\ A ``Market Maker'' means a Streaming Quote Trader or a 
Remote Streaming Quote Trader who enters quotations for his own 
account electronically into the System. See Phlx Options 1, Section 
1(b)(28).
---------------------------------------------------------------------------

    The text of the proposed rule change is available on the Exchange's 
website at <a href="https://listingcenter.nasdaq.com/rulebook/phlx/rulefilings">https://listingcenter.nasdaq.com/rulebook/phlx/rulefilings</a> 
and at the principal office of the Exchange.

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 its Pricing Schedule at Options 7, 
Section 9, B, Port Fees, to propose a limit on the number of SQF Ports 
a Market Maker may subscribe to in a month.
    Currently, a Phlx Market Maker is assessed an SQF Port Fee of 
$1,375 per port, per month up to a maximum of $46,200 per month for 
active ports.\5\ Currently, the Exchange has no limits in place on the 
number of SQF Ports a Market Maker may acquire in a month.
---------------------------------------------------------------------------

    \5\ An active port receives inbound quotes at any time within 
that month.
---------------------------------------------------------------------------

    At this time, the Exchange proposes to limit a Market Maker to no 
more than 250 SQF Ports per month, regardless of whether the SQF Ports 
are active ports.\6\ Further, the Exchange proposes a separate limit of 
250 SQF Ports per month applies to any SQF Ports that are being 
acquired in anticipation of the November 2025 technology migration 
(``Fusion Ports'').\7\ A Market Maker requires only one SQF Port to 
submit quotes in its assigned options series into Phlx. While a Market 
Maker may elect to obtain multiple SQF Ports to organize its 
business,\8\ only one SQF Port is necessary for a Market Maker to 
fulfill its regulatory quoting obligations.\9\ The

[[Page 36203]]

Exchange utilizes ports as a secure method for members and member 
organizations to submit quotes into the Exchange's match engine and for 
the Exchange to send messages related to those quotes to members and 
member organizations. In order to properly regulate its members and 
member organizations and secure the trading environment, the Exchange 
has taken measures to ensure access is monitored and maintained with 
various controls. The Exchange believes that the proposed limit of 250 
SQF Ports per month for current SQF Ports, regardless of whether they 
are active and a separate limit of 250 SQF Ports for Fusion Ports, will 
permit the Exchange to obtain greater efficiencies by placing this 
overall limit on SQF Ports. The Exchange believes these limits will 
provide it with the appropriate bandwidth to support future growth and 
new Market Makers entrants.\10\
---------------------------------------------------------------------------

    \6\ The Exchange issued Options Technical Alert #2025-12 to 
announce the limitation.
    \7\ See <a href="https://www.nasdaqtrader.com/MicroNews.aspx?id=OTU2025-6">https://www.nasdaqtrader.com/MicroNews.aspx?id=OTU2025-6</a>. Phlx members and member organizations will need to acquire new 
ports to connect to the new technology platform to accommodate the 
symbol migration plan.
    \8\ 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 or member organization.
    \9\ 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 ports utilized for quoting on Phlx and only 
Market Makers may utilize these ports.
    \10\ The Exchange will periodically review the SQF Port limit. 
If the Exchange elects to amend the limit it will file a rule 
proposal with the Commission.
---------------------------------------------------------------------------

    The Exchange proposes to implement the 250 SQF Ports per month 
limit on August 15, 2025.
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 Section 
6(b)(5) of the Act,\12\ in particular, in that it is designed to 
promote just and equitable principles of trade, 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.
---------------------------------------------------------------------------

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

    The Exchange's proposal to limit a Market Maker to no more than 250 
SQF Ports per month is consistent with the Act because it will allow 
the Exchange to obtain greater efficiencies in its overall connectivity 
management. The Exchange utilizes ports as a secure method for members 
and member organizations to submit quotes into the Exchange's match 
engine and for the Exchange to send messages related to those quotes to 
members and member organizations. Only Phlx members and member 
organizations who are approved as Market Makers may utilize an SQF 
Port. Once approved, Phlx Market Makers may subscribe to SQF Ports to 
submit quotes into the Exchange. While a Market Maker may elect to 
obtain multiple SQF Ports to organize its business,\13\ only one SQF 
Port is necessary for a Market Maker to fulfill its regulatory quoting 
obligations.\14\ Today, most Market Makers are in possession of several 
SQF Ports, and amend the number of SQF Ports from time to time. Of 
note, Phlx allows members and member organizations to obtain SQF Ports 
at no additional cost once they exceed a monthly fee cap,\15\ therefore 
Market Makers on Phlx may be inclined to increase their total number of 
SQF Ports as a result of having no incremental cost from the Exchange 
because of the monthly fee cap. In fact, not all SQF Ports are actively 
used by Market Makers. In order to properly regulate its members and 
member organizations and secure the trading environment, the Exchange 
has taken measures to ensure access is monitored and maintained with 
various controls that will protect investors and the public interest. 
Specifically, the Exchange ensures that information security 
safeguards, upgrades, and general port management are in effect for all 
SQF Ports regardless of whether the SQF Port is actively in use. As a 
result of these efforts, the Exchange incurs costs to manage and 
maintain its SQF Ports and the secure environment surrounding its 
platform.
---------------------------------------------------------------------------

    \13\ See supra note 8.
    \14\ See supra note 9.
    \15\ Phlx assesses SQF Port Fees up to a maximum of $46,200 per 
month.
---------------------------------------------------------------------------

    The Exchange's proposal is intended to permit it to govern its 
connectivity management in a reasonable manner while protecting 
investors and the general public by obtaining greater efficiencies with 
the limit on SQF Ports. The Exchange believes that its proposal is 
consistent with the Act in that it will provide the Exchange the 
ability to maintain the appropriate bandwidth to support future growth 
and new Market Makers entrants thereby removing impediments to and 
perfect the mechanism of a free and open market.

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 necessary or appropriate in 
furtherance of the purposes of the Act.
    In terms of intra-market competition, the Exchange does not believe 
that its proposal will place any category of market participant at a 
competitive disadvantage. While some Market Makers currently have more 
than 250 SQF Ports, the Exchange notes that the proposed limit would be 
applied uniformly ensuring that no Market Maker has more than 250 SQF 
Ports per month as a result of the proposed limit.
    The Exchange does not believe that its proposal will place an undue 
burden on intra-market competition because any exchange may elect to 
adopt a similar limit.

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

    No written comments were either solicited or received.

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

    Because the foregoing proposed rule change does not: (i) 
significantly affect the protection of investors or the public 
interest; (ii) impose any significant burden on competition; and (iii) 
become operative for 30 days from the date on which it was filed, or 
such shorter time as the Commission may designate, it has become 
effective pursuant to Section 19(b)(3)(A)(iii) of the Act \16\ and 
subparagraph (f)(6) of Rule 19b-4 thereunder.\17\
---------------------------------------------------------------------------

    \16\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \17\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6) 
requires a self-regulatory organization to give the Commission 
written notice of its intent to file 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. 
The Exchange has satisfied this requirement.
---------------------------------------------------------------------------

    A proposed rule change filed under Rule 19b-4(f)(6) \18\ normally 
does not become operative prior to 30 days after the date of the 
filing. However, pursuant to Rule 19b-4(f)(6)(iii),\19\ the Commission 
may designate a shorter time if such action is consistent with the 
protection of investors and the public interest. The Exchange has asked 
the Commission to waive the 30-day operative delay so that the proposed 
rule change may become operative immediately upon filing. The Exchange 
requests that the Commission waive the 30-day operative delay contained 
in Rule 19b-4(f)(6)(iii) so that the Exchange may implement the 
proposal on August 15, 2025. The Exchange notes that MRX does not 
prorate SQF Port Fees and, therefore, the Exchange requests that the 
Commission waive the operative delay so that the 250 SQF Port Fee limit 
may be in place prior to the beginning of September so that the 
Exchange can manage billing for its Members.
---------------------------------------------------------------------------

    \18\ 17 CFR 240.19b-4(f0(6).
    \19\ 17 CFR 240.19b-4(f)(6)(iii).
---------------------------------------------------------------------------

    The Commission believes that waiver of the operative delay is 
consistent with the protection of investors and the

[[Page 36204]]

public interest. The Exchange issued an Options Technical Alert to 
announce the limitation. The Exchange states that the proposed rule 
change is intended to permit it to govern its connectivity management 
in a reasonable manner while protecting investors and the general 
public by obtaining greater efficiencies with the limit on SQF Ports 
and will provide the Exchange the ability to maintain the appropriate 
bandwidth to support future growth and new Market Makers entrants. In 
addition, the Exchange notes that it does not prorate SQF Port Fees and 
a waiver of the operative delay will allow the 250 SQF Port Fee limit 
to be in place at the beginning of the month so that the Exchange can 
manage billing for its Participants. Accordingly, the Commission hereby 
waives the 30-day operative delay and designates the proposed rule 
change operative upon filing.\20\
---------------------------------------------------------------------------

    \20\ For purposes only of waiver the 30-day operative delay, the 
Commission has also considered the proposed rule's impact on 
efficiency, competition, and capital formation. See 15 U.S.C. 
78c(f).
---------------------------------------------------------------------------

    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 shall institute proceedings to 
determine whether the proposed rule should be approved or disapproved.
