Summary

SEC published Cboe BZX Exchange's proposed rule change to amend Rules 11.9(c)(11) and 11.13(a)(4)(C)-(D) to clarify the behavior of Non-Displayed Orders on the BZX Book. The proposed amendments would describe how Non-Displayed Orders execute against previously posted orders, their posting price when they cannot execute, and circumstances under which later-arriving orders may execute ahead of resting Non-Displayed Orders in a locked state. SEC is soliciting comments from interested persons.

What changed

The Exchange proposes to amend Rule 11.9(c)(11) by adding three sub-provisions: Rule 11.9(c)(11)(A) describing execution against previously posted orders up to the full amount unless it would trade through a Protected Quotation; Rule 11.9(c)(11)(B)(i)-(iii) describing posting prices when orders cannot execute, including price slide instructions, cancellation, or routing instructions, and a new provision allowing later-arriving orders to execute ahead of resting Non-Displayed Orders in a locked state.

Affected parties including broker-dealers, investors, and market participants trading on BZX should review the proposed amendments and consider submitting comments. The changes would provide greater certainty regarding order entry and execution of Non-Displayed Orders, align BZX rules with recently approved EDGX Exchange rules, and modify priority rules for resting orders in locked states.

Content

April 14, 2026. 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 April 8, 2026, Cboe BZX Exchange, Inc. (the “Exchange” or “BZX”) filed with the Securities
and Exchange Commission (the “Commission”) the proposed rule change as described in Items I and II below, which Items have
been prepared by the Exchange. The Exchange filed the proposal as a “non-controversial” proposed rule change pursuant to Section
19(b)(3)(A)(iii) of the Act (3) and Rule 19b-4(f)(6) thereunder. (4) The Commission is publishing this notice to solicit comments on the proposed rule change from interested persons.

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

Cboe BZX Exchange, Inc. (the “Exchange” or “BZX”) is filing with the Securities and Exchange Commission (“Commission”) a proposal
to amend Rule 11.9(c)(11) and Rule 11.13(a)(4)(C)-(D) to describe the behavior of Non-Displayed Orders. The

text of the proposed rule change is provided in Exhibit 5.

The text of the proposed rule change is also available on the Commission's website (https://www.sec.gov/rules/sro.shtml), the Exchange's website (https://www.cboe.com/us/equities/regulation/rule_filings/bzx/), 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 Rule 11.9(c)(11) and Rule 11.13(a)(4)(C)-(D) to describe the behavior of Non-Displayed Orders.
The Commission recently approved a filing by the Exchange's affiliate exchange, Cboe EDGX Exchange, Inc. (hereinafter “EDGX”
or “EDGX Exchange”), to implement a substantially similar amendment to EDGX Exchange Rule 11.6(e)(2) and Rule 11.10(a)(4)(C)-(D)
in conjunction with EDGX's proposal to introduce a Retail Price Improvement (“RPI”) program (the “EDGX RPI Filing”). (5) The Exchange proposes to amend Rule 11.9(c)(11) and Rule 11.13(a)(4)(C) to become substantially similar to EDGX Exchange Rule
11.6(e)(2) and Rule 11.10(a)(4)(C)-(D), which as described above, were recently approved by the Commission. The only differences
between the proposed Rules and the EDGX Rules are references to corresponding rules within the BZX Rulebook that differ from
the EDGX Rulebook. The Exchange is also not proposing to introduce an RPI Program as was contained in the EDGX RPI Filing.

By way of background, the Exchange currently permits orders to be entered as Non-Displayed Orders pursuant to Rule 11.9(c)(11).
Current Rule 11.9(c)(11) states that a Non-Displayed Order is “[a] market or limit order that is not displayed on the Exchange.”
The Exchange now proposes to amend Rule 11.9(c)(11) and Rule 11.13(a)(4)(C)-(D) in order to more accurately describe the price
at which a Non-Displayed Order posts to the BZX Book (6) and at what price a Non-Displayed Order may execute in certain situations. The Exchange believes the proposed amendments to
Rule 11.9(c)(11) and Rule 11.13(a)(4)(C)-(D) are necessary in order to provide market participants with greater certainty
and clarity regarding the current entry and execution of orders with Non-Displayed instructions on the Exchange. The Exchange
also believes the proposed amendments are necessary to align the rules of the Exchange with the rules of its affiliate, EDGX
Exchange.

Specifically, the Exchange proposes to introduce Rule 11.9(c)(11)(A), which provides that when a Non-Displayed Order is entered,
the Non-Displayed Order will be executed against previously posted orders on the BZX Book that are priced equal to or better
than the price of the Non-Displayed Order, up to the full amount of such previously posted orders, unless such executions
would trade through a Protected Quotation. (7) Any portion of a Non-Displayed Order that cannot be executed in this manner will be posted to the BZX Book, (unless the Non-Displayed
Order has a time-in-force of Immediate-or-Cancel (“IOC”) (8)) and/or routed if it has been designated as a routable order.

Next, the Exchange next proposes to introduce Rule 11.9(c)(11)(B), which describes the price at which a Non-Displayed Order
is posted and ranked on the BZX Book in the event that it is not executed pursuant to proposed Rule 11.9(c)(11)(A). Proposed
Rule 11.9(c)(11)(B)(i) provides if the limit price of a Non-Displayed Order would lock the BZX Book, the Non-Displayed Order
will be posted on the BZX Book at the locking price and will be executed as set forth in Rule 11.13(a)(4)(C)[sic]. If, however,
an inbound Non-Displayed Order cannot execute due to User (9) instruction (e.g., Post Only (10) or minimum quantity) and does not contain a price slide instruction, the Non-Displayed Order will be cancelled. An inbound
Non-Displayed Order that cannot execute upon entry and contains a price slide instruction will be ranked at the locking price
upon entry. Proposed Rule 11.9(c)(11)(B)(ii) provides if the limit price of the Non-Displayed Order would cross a Protected
Quotation and the Non-Displayed Order contains a price slide instruction, the Non-Displayed Order will be executed as set
forth in Rule 11.9(g)(1) or cancel, based on User instruction. If the entered limit price of the Non-Displayed Order would
cross a Protected Quotation and the Non-Displayed Order does not contain a price slide instruction, the Non-Displayed Order
will cancel or route, based on User instruction. Proposed Rule 11.9(c)(11)(B)(iii) provides that in situations where there
is a resting Non-Displayed Order on the buy (sell) side of the market and an incoming Non-Displayed Order on the sell (buy)
side of the market is unable to execute due to User instruction (e.g., Post Only or minimum quantity) and posts to the BZX Book at a price that locks the resting Non-Displayed Order, an incoming
Non-Displayed Order on the buy (sell) side of the market may execute with the resting Non-Displayed Order on the sell (buy)
side of the market at the locking price ahead of the Non-Displayed Order on the buy (sell) side of the market. The Exchange
believes that it is more appropriate to permit later-arriving orders to execute ahead of a resting order posted to the BZX
Book that is in a locked state due to the presence of a contra-side order with specific User instructions (e.g., Post Only or minimum quantity) rather than cancel or slide the later-arriving order due to the information leakage that would
occur as a result of the cancellation. The Exchange has included an example to demonstrate this operation, which is contained
in proposed Rule 11.9(c)(11)(B)(iii).

Example
  • NBBO for security ABC is $10.00 × $10.05.
    • User 1 enters a Mid-Point Peg (11) order to buy 100 shares of ABC at $10.03. User 1's order is posted to the BZX Book and ranked at $10.025.

  • User 2 enters a Mid-Point Peg Post Only order to sell 100 shares of ABC at $10.02. User 2's order is posted to the BZX Book
    and ranked at $10.025.

  • User 3 enters an IOC Order to buy 100 shares of ABC at $10.05.
    Result: Pursuant to proposed Rule 11.9(c)(11)(B)(iii), User 3's order trades with User 2's Mid-Point Peg Post Only order at a price
    of $10.025. In this instance, User 3's order trades with User 2's order ahead of User 1's order because when User 2's order
    was originally entered, it was unable to execute due to the Post Only instruction. As both User 2's order and User 1's order
    are non-displayed orders (Mid-Point Peg orders by nature are non-displayed), the Exchange allows User 2's order to post to
    the BZX Book and be ranked at the locking price as the non-displayed nature of these orders would not cause a violation of
    Regulation NMS. The Exchange believes that if it were instead to slide User 2's order in accordance with Rule 11.9(g)(2) or
    cancel User 2's order so that it would not create an internal locked book, the act of sliding or cancelling User 2's order
    would result in information leakage. As such, the Exchange believes that it is appropriate to permit User 3's order to trade
    ahead of User 1's resting order at a price of $10.025.

Finally, the Exchange also proposes to amend Rule 11.13(a)(4)(C)-(D) to better describe the execution of Non-Displayed Orders
in situations where a locked market exists on the BZX Book. Rule 11.13(a)(4)(C) currently states that certain orders are permitted
to post and rest on the BZX Book at prices that lock contra-side liquidity, provided, however, that the System will never
display a locked market. The Exchange proposes to add language to Rule 11.13(a)(4)(C) to provide that consistent with Rule
11.12, which sets forth the Exchange's rule regarding priority of orders, Non-Displayed Orders and orders subject to display-price
sliding as set forth in Rule 11.9(g)(1) (defined as the “Resting Orders”) cannot be executed pursuant to Rule 11.13 when such
Resting Orders would be executed at prices equal to displayed orders on the opposite side of the market (the “Locking Price”). (12) The Exchange also proposes to amend Rule 11.13(a)(4)(D) to conform with the proposed changes in Rule 11.13(a)(4)(C) with regard
to the use of the terms Resting Order and Locking Price. Proposed Rule 11.13(a)(4)(D) will be revised from its current text
to provide that in the event that an incoming order described in sub-paragraphs (A) and (B) is a Market Order or is a Limit
Order priced more aggressively than the Locking Price of a Resting Order as described in sub-paragraph (C), the Exchange will
execute the Resting Order at, in the case of a Resting Order bid, one-half minimum price variation less than the Locking Price,
and, in the case of a Resting Order offer, one-half minimum price variation more than the Locking Price.

The proposed changes to Rule 11.9(c)(11) and Rule 11.13(a)(4)(C)-(D) will describe the current behavior of orders containing
a Non-Displayed instruction in greater detail and align the rules of the Exchange with its affiliate exchange, EDGX. The Exchange
is not proposing to amend its current functionality regarding Non-Displayed Orders, but rather seeks to amend its rules so
that Users and other market participants will have greater certainty and clarity regarding how a Non-Displayed Order is posted
and ranked on the BZX Book during certain scenarios involving locked and crossed markets.

2. Statutory Basis

The Exchange believes the proposed rule change is consistent with the Securities Exchange Act of 1934 (the “Act”) and the
rules and regulations thereunder applicable to the Exchange and, in particular, the requirements of Section 6(b) of the Act. (13) Specifically, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) (14) requirements that the rules of an exchange be 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 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) (15) requirement that the rules of an exchange not be designed to permit unfair discrimination between customers, issuers, brokers,
or dealers.

The Exchange believes the proposed amendments to Rule 11.9(c)(11) and Rule 11.13(a)(4)(C)-(D) to introduce additional rule
text describing the entry and execution of Non-Displayed Orders on the Exchange promote just and equitable principles of trade
by providing additional certainty and clarity to market participants regarding how the System processes Non-Displayed Orders.
Specifically, the Exchange seeks to provide additional information regarding the price at which a Non-Displayed Order is posted
and ranked on the BZX Book when a Non-Displayed Order either locks or crosses a Protected Quotation or when a Non-Displayed
Order locks the BZX Book. Further, the Exchange is not proposing to amend Non-Displayed Order behavior, but rather only seeking
to introduce additional language to its rules to provide additional explanation and clarity to Users and market participants
about Non-Displayed Order behavior during a locked or crossed market scenario. By introducing the proposed rule text, Users
will have a better understanding of how a Non-Displayed Order is posted and ranked during certain scenarios involving locked
and crossed markets, which benefits all Users and the marketplace as a whole.

Additionally, the Exchange believes its proposal to introduce additional rule text describing the entry and execution of Non-Displayed
Orders on the Exchange is not unfairly discriminatory as all Users and market participants will be subject to the same application
of the Exchange's rules and will have equal access to the Exchange rulebook. Finally, the Exchange notes that the

proposed text of Rule 11.9(c)(11) and Rule 11.13(a)(4)(C)-(D) has already been approved by the Commission for the Exchange's
affiliate exchange. (16) Indeed, the proposed amendments are substantially similar those approved by the Commission for EDGX Exchange with differences
only to account for the Exchange's existing rule text. Thus, the proposed amendments to Rule 11.9(c)(11) and Rule 11.13(a)(4)(C)-(D)
do not present any novel issues for the Commission's consideration.

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

The Exchange does not believe that the proposed rule changes will impose any burden on competition that is not necessary or
appropriate in furtherance of the purposes of the Act. The Exchange believes that the proposed changes do not impose any burden
on intramarket or intermarket competition that is not necessary or appropriate in furtherance of the purposes of the Act.
The proposed changes to Rule 11.9(c)(11) and Rule 11.13(a)(4)(C)-(D) are not proposed for competitive reasons but rather to
provide Users with additional clarity and transparency about what price a Non-Displayed Order is posted, ranked, and executed
during certain scenarios involving locked and crossed markets. Nor do the proposed changes modify the functionality or behavior
of Non-Display Orders or any other order type on the Exchange. Rather, the proposed rule changes clarify the current functionality
and behavior of Non-Displayed Orders on the Exchange. The proposed rule changes will also align the Exchange's rule text with
that of its affiliate exchange, EDGX. Finally, all Users and market participants will be subject to the same application of
the Exchange's rules and will have equal access to the Exchange rulebook. Thus, the proposed rule changes add clarity and
transparency to the rules of the Exchange regarding Non-Displayed Orders and will not impose any burden on intramarket or
intermarket competition.

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

Others

The Exchange neither solicited nor received comments on the proposed rule change.

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 (17) and Rule 19b-4(f)(6) (18) thereunder.

The Exchange has requested that the Commission waive the 30-day operative delay contained in Rule 19b-4(f)(6)(iii) so that
the proposed rule change may become operative upon filing. The Exchange states that the proposed rule change will align the
Exchange Rules regarding treatment of Non-Displayed Order with that of the Exchange's affiliate, EDGX. Because the proposed
rule change does not raise any novel regulatory issues, the Commission believes that waiver of the operative delay is consistent
with the protection with the protection of investors and the public interest. Accordingly, the Commission hereby waives the
operative delay and designates the proposal operative upon filing. (19)

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

(6) See Rule 1.5(e). The term “BZX Book” shall mean the System's electronic file of orders.

(7) See Rule 1.5(t). The term “Protected Bid” or “Protected Offer” shall mean a bid or offer in a stock that is (i) displayed by an
automated trading center; (ii) disseminated pursuant to an effective national market system plan; and (iii) an automated quotation
that is the best bid or best offer of a national securities exchange or association. The term “Protected Quotation” shall
mean a quotation that is a Protected Bid or Protected Offer.

(8) See Exchange Rule 11.9(b)(1). An Immediate-or-Cancel (“IOC”) Order is a limit order that is to be executed in whole or in part
as soon as such order is received. The portion not executed immediately on the Exchange or another trading center is treated
as cancelled and is not posted to the BZX Book. IOC limit orders that are not designated as “BZX Only” and that cannot be
executed in accordance with Rule 11.13(a)(4) on the System when reaching the Exchange will be eligible for routing away pursuant
to Rule 11.13(b).

(9) See Rule 1.5(cc). The term “User” shall mean any Member or Sponsored Participant who is authorized to obtain access to the System
pursuant to Rule 11.3.

(10) See Rule 11.9(c)(6). A Post Only Order is an order that is to be ranked and executed on the Exchange pursuant to Rule 11.12 and
Rule 11.13(a)(4) or cancelled, as appropriate, without routing away to another trading center except that the order will not
remove liquidity from the BZX Book, other than as described below. A BZX Post Only Order will remove contra-side liquidity
from the BZX Book if the order is an order to buy or sell a security priced below $1.00 or if the value of such execution
when removing liquidity equals or exceeds the value of such execution if the order instead posted to the BZX Book and subsequently
provided liquidity, including the applicable fees charged or rebates provided.

(11) See Rule 11.9(c)(9). A Mid-Point Peg Order is a limit order that after entry into the System, the price of the order is automatically
adjusted by the System in response to changes in the NBBO to be pegged to the mid-point of the NBBO, or, alternatively, pegged
to the less aggressive of the midpoint of the NBBO or one minimum price variation inside the same side of the NBBO as the
order.

(12) Any incoming order that would execute against the Resting Order at the Locking Price would receive a priority advantage over
the displayed order at the Locking Price. As such, the Exchange does not execute a Resting Order against an incoming order
at the Locking Price if there is also a displayed order resting on the BZX Book at the Locking Price.

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.

(19) For purposes only of waiving the 30-day operative delay, the Commission has considered the proposed rule's impact on efficiency,
