[Release No. 34-104380; File No. SR-MIAX-2025-48]
Self-Regulatory Organizations; Miami International Securities
Exchange, LLC; Notice of Filing and Immediate Effectiveness of a
Proposed Rule Change To Delay Implementation of the Change To Amend the
Administrative Information Subscriber Market Data Feed
December 12, 2025.
Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934
(the ``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given
that on December 2, 2025, Miami International Securities Exchange, LLC
(``MIAX'' or the ``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 delay implementation of the change to
amend the Administrative Information Subscriber market data feed to
include the origin code on liquidity seeking event notifications.
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 the Exchange'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 the origin code in liquidity seeking event notifications.\3\
The proposed rule change indicated that the Exchange would announce the
implementation date of the proposed rule change by Regulatory Circular
to be published no later than 90 days following the operative date of
the proposed rule. Additionally, the proposed rule change provided that
the implementation date would be no later than 90 days following the
issuance of the Regulatory Circular. The Exchange has not issued a
Regulatory Circular and now proposes to delay the implementation of
this functionality until the second quarter of 2026.
---------------------------------------------------------------------------
\3\ See Securities Exchange Act Release No. 104011 (September
22, 2025), 90 FR 46295 (September 25, 2025) (SR-MIAX-2025-43).
---------------------------------------------------------------------------
The Exchange proposes this delay in order to allow the Exchange and
its Members ample time to complete the necessary technical changes
prior to the implementation of the change to the AIS Feed. The Exchange
proposes to issue a Regulatory Circular notifying market participants
at least 45 days prior to implementing this functionality.
2. Statutory Basis
The Exchange believes that its proposed rule change is consistent
with Section 6(b) of the Act \4\ in general, and furthers the
objectives of Section 6(b)(5) of the Act \5\ 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 general, to protect investors and the public interest by
allowing the Exchange and its Members additional time to implement the
proposed change.
---------------------------------------------------------------------------
\4\ 15 U.S.C. 78f(b).
\5\ 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
impose any burden on competition that is not
[[Page 58642]]
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 which affects MIAX
Members only 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
The Exchange has filed the proposed rule change pursuant to Section
19(b)(3)(A)(iii) of the Act \6\ and Rule 19b-4(f)(6) thereunder.\7\
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) of the Act \8\ and Rule 19b-
4(f)(6) \9\ thereunder.
---------------------------------------------------------------------------
\6\ 15 U.S.C. 78s(b)(3)(A)(iii).
\7\ 17 CFR 240.19b-4(f)(6).
\8\ 15 U.S.C. 78s(b)(3)(A)
\9\ Rule 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, 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.
---------------------------------------------------------------------------
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) \10\ of the Act to determine whether the proposed
rule change should be approved or disapproved.
---------------------------------------------------------------------------
\10\ 15 U.S.C. 78s(b)(2)(B).
