    \2\ 17 CFR 240.19b-4.
---------------------------------------------------------------------------

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

    The Exchange is filing a proposal to delay implementation of the 
proposed change to provide origin code in the liquidity seeking event 
notification messages on the Administrative Information Subscriber 
(``AIS'') feed.
    The text of the proposed rule change is available on the Exchange's 
website at <a href="https://www.miaxglobal.com/markets/us-options/all-options-exchanges/rule-filings">https://www.miaxglobal.com/markets/us-options/all-options-exchanges/rule-filings</a> and at MIAX's principal office.

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
    On September 11, 2025, the Exchange filed a proposal to amend the 
Administrative Information Subscriber market data feed (``AIS Feed'') 
to include origin code in the liquidity seeking event notification 
message.\3\ The proposal indicated that the Exchange would announce the 
implementation date of the proposal in a Regulatory Circular to be 
published no later than 90 days after the publication of the approval 
order in the Federal Register. Further, the Exchange proposed that the 
implementation date would be no later than 90 days following the 
publication of the Regulatory Circular announcing publication of the 
approval order in the Federal Register.\4\ The Exchange has not issued 
a Regulatory Circular as described above and now proposes to delay the 
implementation of this functionality until Q4 2026.
---------------------------------------------------------------------------

    \3\ See Securities Exchange Act Release No. 1104011 (September 
11, 2025), 90 FR 46295 (September 22, 2025) (SR-MIAX-2025-43).
    \4\ The original proposal (SR-MIAX-2025-43) was submitted as a 
19(b)(3)(A) filing and as such the filing was deemed immediately 
effective upon filing subject to a 30 day operative delay and would 
not have received an approval order.
---------------------------------------------------------------------------

    The Exchange proposes this delay in order to allow the Exchange and 
its Members \5\ ample time to complete the necessary technical changes 
prior to the implementation of the change. The Exchange proposes to 
issue a Regulatory Circular notifying market participants at least 30 
days prior to implementing this functionality.
---------------------------------------------------------------------------

    \5\ The term ``Member'' means an individual or organization 
approved to exercise the trading rights associated with a Trading 
Permit. Members are deemed ``members'' under the Exchange Act. See 
Exchange Rule 100.
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes that its proposed rule change is consistent 
with Section 6(b) of the Act \6\ in general, and furthers the 
objectives of Section 6(b)(5) of the Act \7\ 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 mechanisms of a free and open market and a national market 
system and, in

[[Page 10657]]

general, to protect investors and the public interest by allowing the 
Exchange and its Members additional time to implement the proposed 
change.
---------------------------------------------------------------------------

    \6\ 15 U.S.C. 78f(b).
    \7\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

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's 
proposal to delay the implementation of the proposed functionality does 
not impose an undue burden on competition. Delaying the implementation 
will simply allow the Exchange and its Members additional time to 
properly prepare for, and implement, the proposed functionality.
    The Exchange does not believe that the proposed rule change will 
impose any burden on intramarket competition as the delay will apply 
equally to all Members of the Exchange.
    The Exchange does not believe that the proposed rule change will 
impose any burden on intermarket competition as the proposal is to 
delay the implementation of approved functionality and does not impact 
intermarket competition.

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

    Written comments were neither solicited nor received.

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

    Pursuant to Section 19(b)(3)(A) of the Act \8\ and Rule 19b-4(f)(6) 
\9\ thereunder, the Exchange has designated this proposal as one that 
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.
---------------------------------------------------------------------------

    \8\ 15 U.S.C. 78s(b)(3)(A).
    \9\ 17 CFR 240.19b-4(f)(6).
---------------------------------------------------------------------------

    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.
