of the Proposed Rule Change

    Pursuant to the provisions of Section 19(b)(1) under the Act,\4\ 
and Rule 19b-4 thereunder,\5\ the Exchange is filing with the

and 11.410(a)(2) to include Texas Stock Exchange (``TXSE'') in the list 
of away trading centers to which the Exchange routes and the market 
data sources the Exchange will use for necessary price reference points 
in anticipation of TXSE's planned launch. The Exchange has designated 
this rule change as ``non-controversial'' under Section 19(b)(3)(A) of

II. Self-Regulatory Organization's Statement of the Purpose of, and the 
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 these statements may be examined at 
the places specified in Item IV below. The self-regulatory organization 
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 the 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The Exchange proposes to amend IEX Rules 2.220(a)(7) \8\ and 
11.410(a) \9\ to include TXSE in the list of away trading centers to 
which the Exchange routes and the market data sources the Exchange will 
use to determine Top of Book \10\ quotations, the NBBO \11\ and certain 
regulatory, reporting and compliance systems within IEX in anticipation 
of TXSE's planned exchange launch in July 2026.\12\ The Exchange 
proposes to amend the IEX Rule 2.220(a)(7) to add TXSE to the list of 
away trading centers to which IEX Services routes orders. As set forth 
in IEX Rule 11.230(b)(2), IEX Services routes eligible orders to away 
trading centers with accessible Protected Quotations in compliance with 
Regulation NMS Rule 611.\13\ IEX Rule 2.220(a)(7) lists the away 
trading centers that IEX Services routes to as outbound router for the 
Exchange. The Exchange must include TXSE in its list of away trading 
centers to which it routes because TXSE's best-priced, displayed 
quotation will be a Protected Quotation under Regulation NMS Rule

[[Page 33268]]

600(b)(62) \14\ for purposes of Regulation NMS Rule 611.\15\
---------------------------------------------------------------------------

    \8\ IEX Rule 2.220(a)(7) lists the away trading centers that IEX 
Services LLC (``IEX Services'') routes to as outbound router for the 
Exchange.
    \9\ IEX Rule 11.410(a) specifies the market data sources for 
each away trading center that the Exchange uses for necessary price 
reference points.
    \10\ See IEX Rule 11.410(a)(1).
    \11\ See IEX Rule 1.160(u).
    \12\ TXSE anticipates commencing trading on July 6, 2026. See 
TXSE Production Launch and Market Activation, dated May 6, 2026, 
available at <a href="https://www.txse.com/alerts/txse-2026-002">https://www.txse.com/alerts/txse-2026-002</a>.
    \13\ 17 CFR 242.611.
    \14\ 17 CFR 242.600(b)(62).
    \15\ See Securities Exchange Act Release No. 104146 (September 
30, 2025), 90 FR 47880 (October 2, 2025) (Order approving Texas 
Stock Exchange LLC application for registration as a national 
securities exchange).
---------------------------------------------------------------------------

    The Exchange also proposes to amend and update the table in IEX 
Rule 11.410(a) specifying the primary source for TXSE market data. IEX 
Rule 11.410(a) lists the specific data feeds the Exchange uses to 
determine Top of Book quotations for away exchanges, the NBBO and for 
certain reporting, regulatory and compliance systems within IEX. The 
Exchange proposes to amend the table in IEX Rule 11.410(a) to specify 
that the Exchange will use securities information processor (``SIP'') 
data, i.e., CQS SIP data for securities reported under the Consolidated 
Quotation Services and Consolidated Tape Association plans and UQDF SIP 
data for securities reported under the Nasdaq Unlisted Trading 
Privileges plan, as the primary source of market data used to determine 
TXSE's Top of Book quotes. The Exchange also proposes to make a 
conforming change to the rule text of Rule 11.410(a)(2) so that the 
provision is consistent with the table in Rule 11.410(a). The proposed 
changes do not alter the manner in which orders are handled or routed 
by the Exchange.
    The Exchange proposes to make these changes operative on the date 
that TXSE launches operations.
2. Statutory Basis
    IEX believes that the proposed rule changes are consistent with the 
provisions of Section 6(b) \16\ of the Act in general, and furthers the 
objectives of Section 6(b)(5) of the Act \17\ in particular, in that 
they are designed to prevent fraudulent and manipulative acts and 
practices, 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.
---------------------------------------------------------------------------

    \16\ 15 U.S.C. 78f.
    \17\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    For the reasons discussed in the Purpose section, the Exchange 
believes that the proposed rule changes remove impediments to and 
perfect the mechanism of a free and open market and protect investors 
and the public interest because amending the list of away trading 
centers to which IEX routes by adding TXSE and adding TXSE to the table 
in Rule 11.410(a) and rule text of Rule 11.410(a)(2) designating the 
SIP data as the primary source of market data the Exchange will use to 
determine away trading center Top of Book quotes, the NBBO, and for 
certain regulatory, reporting and compliance systems within IEX, will 
facilitate the Exchange's compliance with the applicable requirements 
of Regulation NMS.
    Additionally, amending the list of away trading centers to which 
IEX routes by adding TXSE and adding TXSE to the table designating the 
SIP data as the primary source of market data the Exchange will use to 
determine away trading center Top of Book quotes, the NBBO, and for 
certain regulatory, reporting and compliance systems within IEX, 
provides transparency with respect to the away trading centers to which 
IEX Services may route orders and the source of market data the 
Exchange will use to determine TXSE's Top of Book quotes.
    Further, the Exchange believes it is consistent with the Act to add 
TXSE to the source of market data the Exchange will use to determine 
Top of Book quotes so that IEX's rules accurately specify away markets 
referenced, as well as to avoid any potential confusion on the part of 
market participants. The Exchange also believes it is consistent with 
the Act to make a conforming change to Rule 11.410(a)(2) so that 
provision is consistent with the table in Rule 11.410(a).
    As noted in the Purpose section, the proposed changes are non-
substantive and do not alter the manner in which orders are handled or 
routed by the Exchange.

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

    IEX does not believe that the proposed rule changes will result in 
any burden on competition that is not necessary or appropriate in 
furtherance of the purposes of the Act. The Exchange believes that the 
proposed updates do not impact competition in any respect since the 
purpose is to enhance transparency with respect to the operation of the 
Exchange and its use of market data feeds.

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) of the Act \18\ and Rule 19b-4(f)(6) \19\ thereunder. 
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; or (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) of the Act \20\ and Rule 19b-4(f)(6) \21\ thereunder.
---------------------------------------------------------------------------

    \18\ 15 U.S.C. 78s(b)(3)(A).
    \19\ 17 CFR 240.19b-4(f)(6).
    \20\ 15 U.S.C. 78s(b)(3)(A).
    \21\ 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) \22\ normally 
does not become operative prior to 30 days after the date of the 
filing. However, pursuant to Rule 19b-4(f)(6)(iii),\23\ 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 
Commission believes that waiving the 30-day operative delay is 
consistent with the protection of investors and the public interest 
because the proposed rule change simply adds TXSE to the list of away 
trading centers to which IEX routes orders and clarifies that SIP data 
will be the primary source of data that the Exchange will utilize for 
determining TXSE's Top of Book quotes. As a result, the proposal does 
not introduce any novel regulatory issues. Waiving the 30-day operative 
delay also will ensure that the IEX rules will be updated to reflect 
the addition of TXSE prior to the commencement of trading on TXSE. 
Accordingly, the Commission designates the proposed rule change to be 
operative upon filing.\24\
---------------------------------------------------------------------------

    \22\ 17 CFR 240.19b-4(f)(6).
    \23\ 17 CFR 240.19b-4(f)(6)(iii).
    \24\ For purposes only of waiving the 30-day operative delay, 
the Commission also has 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

[[Page 33269]]

investors, or otherwise in furtherance of the purposes of the Act. If 
the Commission takes such action, the Commission will institute 
proceedings to determine whether the proposed rule change should be 
approved or disapproved.
