    Pursuant to Section 19(b)(1) \1\ of the Securities Exchange Act of 
1934 (``Act'') \2\ and Rule 19b-4 thereunder,\3\ notice is hereby given 
that, on September 24, 2025, 24X National Exchange LLC (``24X'' or the 
``Exchange'') filed with the Securities and Exchange Commission (the

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

    The Exchange proposes to revise the hours of operation of the 
Exchange. Specifically, the Exchange proposes to change the end time of 
the Post-Market Session to 8 p.m. E.T. rather than 7 p.m. E.T., to 
correspondingly revise the definition of the 24X Market Session to 
preserve a one-hour trading pause (the ``Trading Pause''),\4\ and to 
make other conforming changes. The proposed rule change is available on 
the Exchange's website at https://equities.24exchange.com/regulation 
and at the principal office of the Exchange.
---------------------------------------------------------------------------

    \4\ See 24X Rule 11.5(c)(2).
---------------------------------------------------------------------------

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 self-regulatory organization 
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 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 parts 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 Exchange is filing this proposed rule change to revise the 
hours of operation of the Exchange. Specifically, the Exchange proposes 
to change the end time of the Post-Market Session to 8 p.m. E.T. rather 
than 7 p.m. E.T., to correspondingly revise the definition of the 24X 
Market Session \5\ to preserve the Trading Pause, and to make other 
conforming changes to reflect the changes to these market session 
definitions.
---------------------------------------------------------------------------

    \5\ Pursuant to 24X Rule 1.5(c), the Exchange will not commence 
operation of the 24X Market Session until certain requirements are 
met.
---------------------------------------------------------------------------

a. Background
    24X was approved by the Securities and Exchange Commission as a 
national securities exchange on November 27, 2024 \6\ and plans to 
commence operations on September 29, 2025. 24X Rules currently provide 
for trading sessions that span from 4 a.m. E.T. to 7 p.m. E.T. on each 
U.S. Business Day: \7\ (1) the ``Core Market Session,'' which will 
operate between 9:30 a.m. E.T. and 4 p.m. E.T. on U.S. Business 
Days,\8\ (2) the ``Pre-Market Session,'' which will operate between 4 
a.m. E.T. and 9:30 a.m. E.T. on U.S. Business Days,\9\ and (3) the 
``Post-Market Session,'' which will operate between 4 p.m. E.T. and 7 
p.m. E.T. on U.S. Business Days.\10\ The current 24X Rules also provide 
that once certain requirements are met, another trading session, the 
``24X Market Session,'' \11\ would operate between 8 p.m. E.T. and 4 
a.m. E.T. on Sunday, Monday, Tuesday, Wednesday, and Thursday nights 
that precede a U.S. Business Day.\12\ 24X Rules also provide for the 
Trading Pause from 7 p.m. E.T. until 8 p.m. E.T. on Monday, Tuesday, 
Wednesday, and Thursday nights.\13\
---------------------------------------------------------------------------

    \6\ See Securities Exchange Act Release No. 101777 (November 27, 
2024), 89 FR 97092 (December 6, 2024).
    \7\ See 24X Rule 1.5(ll) defining ``U.S. Business Day.''
    \8\ See 24X Rule 1.5(l) defining the ``Core Market Session.''
    \9\ See 24X Rule 1.5(z) defining the ``Pre-Market Session.''
    \10\ See 24X Rule 1.5(y) defining the ``Post-Market Session.''
    \11\ See 24X Rule 1.5(c) defining the ``24X Market Session.''
    \12\ See 24X Rule 1.5(c).
    \13\ See 24X Rule 11.15(c)(2). This Trading Pause will permit 
24X to address the technical implications of a 23-hour trading day 
and will facilitate industry-wide testing, internal market testing, 
and systems updates and improvements.
---------------------------------------------------------------------------

    24X, however, will not commence operation of the 24X Market Session 
until certain requirements are met. Specifically, Rule 1.5(c) requires 
24X, prior to commencing operation of the 24X Market Session, to file a 
proposed rule change, pursuant to Section 19(b) of the Exchange Act and 
the rules thereunder, to amend its rules confirming that 24X is able to 
comply with its obligations under the Exchange Act during the 24X 
Market Session and that the Equity Data Plans \14\ are prepared to 
collect, consolidate, process, and disseminate quotation and 
transaction information at all times during the 24X Market Session 
(``24X Market Session Proposed Rule Change''). The 24X Market Session 
Proposed Rule Change must be filed with the Commission and be approved,

[[Page 46979]]

or otherwise become effective pursuant to Exchange Act Section 19(b), 
before 24X can offer trading during the 24X Market Session.\15\ Because 
the 24X Market Session will not operate until the aforementioned 
requirements of 24X Rule 1.5(c) are met, 24X will commence trading on 
September 29, 2025 by operating only the Pre-Market Session, Core 
Market Session, and Post-Market Session.
---------------------------------------------------------------------------

    \14\ The term ``Equity Data Plans'' is defined in 24X Rule 
1.5(o) to mean ``the effective national market system plan(s) that 
govern the collection, consolidation, processing and dissemination 
of consolidated equity market data via the exclusive securities 
information processors (``SIPs''), including (1) Consolidated Tape 
Association Plan (``CTA Plan''), (2) Consolidated Quotation Plan 
(``CQ Plan''), (3) the Joint Self-Regulatory Organization Plan 
Governing the Collection, Consolidation and Dissemination of 
Quotation and Transaction Information for Nasdaq-Listed Securities 
Traded on Exchanges on an Unlisted Trading Privileges Basis (``UTP 
Plan''), and (4) any successor thereto to the named Plan(s).''
    \15\ See 24X Rules 1.5(c) and 11.16.
---------------------------------------------------------------------------

b. Proposed Rule Change
    The Exchange proposes to modify its rules to change the end time of 
the Post-Market Session, change the start time of the 24X Market 
Session to preserve the Trading Pause, and make other conforming 
changes. Specifically, the Exchange proposes to amend Rule 1.5(y) 
(Post-Market Session) so that the Post-Market Session would end at 8 
p.m. E.T. instead of 7 p.m. E.T. With this proposal, the Exchange would 
offer the current timing of the Post-Market Session available on other 
national securities exchanges.\16\ The Exchange also proposes to 
correspondingly amend Rule 1.5(c) (24X Market Session) so that the 24X 
Market Session would commence, when applicable, at 9 p.m. E.T. rather 
than 8 p.m. E.T., in order to preserve the Trading Pause.
---------------------------------------------------------------------------

    \16\ See, e.g., Nasdaq Equity 1, Section 1(a)(9).
---------------------------------------------------------------------------

    The proposed revised hours of the Post-Market and 24X Market 
Sessions would not substantively change the operation of the Exchange 
and would allow the Exchange to operate for the same number of hours 
each day as contemplated in the Exchange's existing rules once the 24X 
Market Session becomes operative in accordance with the requirements 
described above. In addition, all NMS stocks would continue to be 
eligible for trading in the proposed revised hours of the Post-Market 
Session. Moreover, as discussed below, the existing safeguards 
applicable to the Post-Market Session including, among other things, 
operational safeguards, availability of consolidated last sale and 
quotation information, specific disclosures to investors regarding the 
heightened risks of after-hours trading, and market surveillance 
capabilities would be applicable to the proposed revised hours of the 
Post-Market and 24X Market Sessions. For the avoidance of doubt, it 
should be clear that the 24X Market Session will only become effective 
consistent with the requirements of Rule 1.5(c).\17\
---------------------------------------------------------------------------

    \17\ See supra notes 11-12.
---------------------------------------------------------------------------

c. Other Conforming Changes
    In addition to the foregoing rule changes, the Exchanges also 
proposes to correspondingly amend: (i) Rule 11.15(c)(2) (Trading 
Pauses) to move the start time of the Trading Pause from 7 p.m. E.T. to 
8 p.m. E.T.; (ii) Rule 1.5(b) (24X Trading Day) to modify the 
definition of the 24X Trading Day; (iii) Rule 11.1(a) and (d) (Hours of 
Trading and Trading Days) to modify the trading rules that describe the 
hours of operation of the Exchange; and (iv) Rule 11.6(o)(4) (Extended 
Hours) and (5) (Good-`til Time) to modify the order entry rules that 
describe the hours of operation of the Exchange. In each case, the 
Exchange proposes these modifications to conform to the proposed 
changes to the definitions of the Post-Market and 24X Market Sessions.
d. Operations
    The proposed revised trading sessions will operate in the same 
manner as the current sessions from an operational perspective. All 
order types eligible for such sessions and order type behaviors will 
remain unchanged.
e. Securities Information Processor (``SIP'') Readiness
    The Exchange will submit all quotes and trades that are generated 
in the proposed revised hours of the Post-Market Session to the 
consolidated quote and trade systems maintained by the SIPs for public 
dissemination. Accordingly, once these proposed revised trading hours 
are operative, quotes and trades will be made available to the 
investing public in the same manner that quotes are currently made 
available.
    The two SIP Plan Processors--the Securities Industry Automation 
Corporation and Nasdaq--both currently operate from 4 a.m. E.T. through 
8 p.m. E.T.
f. Customer Disclosures
    As noted above, given the potential trading and other risks of 
Extended Hours Trading, Rule 3.21 prohibits Members from accepting 
orders for execution during the Pre-Market Session or Post-Market 
Session without making the specified disclosures in Rule 3.21. The 
Exchange notes that these customer disclosure requirements would be 
fully applicable to the proposed revised trading hours of the Post-
Market Session and would place the same disclosure obligations on 
Members.
g. Implementation
    The Exchange will begin accepting orders for the proposed revised 
trading hours of the Post-Market Session subject to the operational 
effectiveness of this proposed rule change.
2. Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the Exchange 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 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.
---------------------------------------------------------------------------

    \18\ 15 U.S.C. 78f(b).
    \19\ 15 U.S.C. 78f(b)(5).
    \20\ Id.
---------------------------------------------------------------------------

    The Exchange believes the proposed rule change would promote just 
and equitable principles of trade, remove impediments to and perfect 
the mechanism of a free and open market and a national market system, 
and, in general, protect investors and the public interest by allowing 
investors to trade on the Exchange during the time that they may trade 
on other national securities exchanges.\21\ As a result, the Exchange 
believes the proposed rule change is not novel or unique, and it 
provides investors with additional flexibility for managing their 
orders. Moreover, the Exchange believes that the proposal will increase 
market accessibility, promote capital formation, and facilitate 
portfolio management. Additionally, the Exchange notes that its rules 
require that disclosures be made to customers describing potential 
risks related to trading in the proposed revised hours of the Post-
Market Session, which will continue to protect investors from any 
additional risks related to trading during that period.
---------------------------------------------------------------------------

    \21\ Id.
---------------------------------------------------------------------------

    The proposed rule change further removes impediments to a free and 
open market and does not unfairly discriminate among market 
participants,

[[Page 46980]]

as all Members of the Exchange will be able, but not be required, to 
participate during the proposed revised trading hours of the Post-
Market Session. Moreover, all Members of the Exchange may participate 
in the proposed revised trading hours of the Post-Market Session in the 
same manner as they would participate in the existing trading hours of 
the Post-Market Session using, for example, the same connection lines, 
message formats, and data feeds, that they currently use, thereby 
eliminating or minimizing any preparation efforts necessary to continue 
to participate. The Exchange therefore believes that the proposed rule 
change is reasonably designed to provide an appropriate mechanism for 
additional trading time during the Post-Market Session while providing 
for appropriate Exchange oversight pursuant to the Act, trade 
reporting, and surveillance.
    Finally, the Exchange believes that applying the current 
requirements of the Post-Market Session, including order designation, 
permitted orders, and mandatory customer disclosures, as well as the 
operational and regulatory safeguards already in place for the current 
Post-Market Session, to the proposed revised trading hours of the Post-
Market Session, would promote just and equitable principles of trade 
and protect investors and the public interest.

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 that is not necessary or appropriate 
in furtherance of the purposes of the Exchange. As discussed above, the 
proposal to modify the trading hours of the Post-Market Session is 
consistent with the rules of other exchanges. As such, the proposed 
rule change would promote competition by allowing the Exchange to trade 
during the proposed revised trading hours of the Post-Market Session in 
the same manner as another national securities exchange currently is 
permitted to trade during that same time period.
    In addition, the Exchange does not believe that the proposed rule 
change to modify the trading hours for Post-Market Sessions will impose 
any burden on intramarket competition that is not necessary or 
appropriate in furtherance of the purposes of the Exchange Act, because 
all Members of the Exchange will be able, but not be required, to 
participate during the proposed revised trading hours of the Post-
Market Session. All Members of the Exchange may participate in the 
proposed revised trading hours of the Post-Market Session in the same 
manner as they would participate in the existing hours of the Post-
Market Session using, for example, the same connection lines, message 
formats, and data feeds that they currently use, thereby eliminating or 
minimizing any preparation efforts necessary to continue to 
participate.
    Moreover, the Exchange operates in a highly competitive environment 
in which unaffiliated exchange competitors and new entrants could 
compete to offer extended hours trading of similar duration, and the 
proposal would therefore enable the Exchange to compete on a more level 
playing field with these competitors.

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

    No written comments were solicited or received with respect to the 
proposed rule change.

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

    Because the 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 prior to 
30 days from the date on which it was filed, or such shorter time as 
the Commission may designate, if consistent with the protection of 
investors and the public interest, the proposed rule change has become 
effective pursuant to Section 19(b)(3)(A) \22\ of the Act and Rule 19b-
4(f)(6) thereunder.\23\
---------------------------------------------------------------------------

    \22\ 15 U.S.C. 78s(b)(3)(A).
    \23\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6)(iii) 
requires the Exchange to give 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. The 
Exchange has satisfied this requirement.
---------------------------------------------------------------------------

    A proposed rule change filed under Rule 19b-4(f)(6) \24\ normally 
does not become operative prior to 30 days after the date of the 
filing. However, pursuant to Rule 19b4(f)(6)(iii),\25\ 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 proposal 
may become operative upon filing. The Commission finds that waiving the 
30-day operative delay is consistent with the protection of investors 
and the public interest. The proposed rule change aligns the Exchange's 
post market session hours with those of other exchanges and will allow 
24X to begin operations as a national securities exchange on September 
29, 2025, as anticipated. Accordingly, the Commission hereby waives the 
30-day operative delay and designates the proposed rule change as 
operative upon filing.\26\
---------------------------------------------------------------------------

    \24\ Id.
    \25\ 17 CFR 240.19b-4(f)(6)(iii).
    \26\ For purposes only of waiving the 30-day operative delay, 
the Commission has also considered the proposed rule's impact on 
efficiency, competition, and capital formation. See U.S.C. 78c(f).
---------------------------------------------------------------------------

    At any time within 60 days of the filing of such 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 under 
Section 19(b)(2)(B) \27\ of the Act to determine whether the proposed 
rule change should be approved or disapproved.
