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

    Cboe C2 Exchange, Inc. (the ``Exchange'' or ``C2'') proposes to 
adopt a new rule governing the operation of a proposed Step Up 
Mechanism (``SUM'') on the Exchange and to make conforming changes in 
other rules. 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 (<a href="https://www.sec.gov/rules/sro.shtml">https://www.sec.gov/rules/sro.shtml</a>), the 
Exchange's website (<a href="https://www.cboe.com/us/options/regulation/rule_filings/ctwo/">https://www.cboe.com/us/options/regulation/rule_filings/ctwo/</a>), 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 adopt Rule 5.35 (Step Up Mechanism 
(``SUM'')), which sets forth the operational framework for SUM, a 
feature within the System that would provide automated order handling 
in designated classes for qualifying orders that are not automatically 
executed by the System. The proposed functionality is substantively 
identical to the Step Up Mechanism of Cboe Exchange, Inc. (``Cboe 
Options'').\3\ The Exchange also proposes to make conforming amendments 
to Rules 5.21, 5.25,\4\ and 5.34.
---------------------------------------------------------------------------

    \3\ See Cboe Options Rule 5.35; see also, e.g., Cboe EDGX 
Exchange, Inc. (``Cboe EDGX'') Rule 21.18; and Investors Exchange 
(``IEX'') Rule 22.270.
    \4\ As part of the proposed changes, the Exchange proposes to 
correct a typographical error in Rule 5.25(c), namely to correct 
``subpargraph'' to ``subparagraph.''
---------------------------------------------------------------------------

    Proposed Rule 5.35(a) sets forth the eligibility requirements for 
SUM. Under the proposed rule, the Exchange will determine \5\ eligible 
order size, eligible order type, eligible order Capacity (e.g., 
Priority Customer orders, non-Market Maker non-Priority Customer 
orders, and Market Maker orders), and classes in which SUM is 
activated. Bulk messages are not eligible for SUM, as bulk messages are 
intended to assist Market-Makers' facilitation of the provision of 
liquidity on the Exchange. SUM will automatically process upon receipt 
of: (1) an eligible order that is marketable against the Exchange's BBO 
\6\ that is not the NBBO;\7\ or (2) an eligible order that would 
improve the Exchange's BBO and that is marketable against the ABBO.\8\ 
The proposed rule change also permits a User to opt out of this 
process.\9\ The Exchange will not initiate the SUM process if the NBBO 
is crossed.
---------------------------------------------------------------------------

    \5\ The Exchange announces to Trading Permit Holders all 
determinations it makes pursuant to the Rules via: specifications, 
Notices, or Regulatory Circulars with appropriate advanced notice, 
which will be posted on the Exchange's website, or as otherwise 
provided in the Rules; electronic message; or other communication 
method as provided in the Rules. See Rule 1.5(a).
    \6\ ``BBO'' means the best bid or offer disseminated on the 
Exchange. See Rule 1.1.
    \7\ ``NBBO'' means the national best bid or offer the Exchange 
calculates based on market information it receives from OPRA. See 
Rule 1.1.
    \8\ ``ABBO'' means the best bid(s) or offer(s) disseminated by 
other Eligible Exchanges (as defined in Section E of Chapter 5) and 
calculated by the Exchange based on market information the Exchange 
receives from OPRA. See Rule 1.1.
    \9\ Users may opt out from SUM on an order-by-order basis or by 
applying a setting to an order entry port that would opt out all 
orders submitted by that User through that port.
---------------------------------------------------------------------------

    Proposed Rule 5.35(b) describes the order handling and response 
process during a SUM exposure period. Upon receipt of a SUM-eligible 
order, the System electronically exposes the order at the NBBO 
immediately upon receipt. The order is exposed for a period of time 
determined by the Exchange \10\ on a class-by-class basis, which period 
of time may not exceed one second. During the exposure period, all 
Users may submit responses to the exposure message. Responses must be 
limited to the size of the order being exposed; may be modified, 
cancelled, or replaced any time during the exposure period; and are 
cancelled back at the end of the exposure period if unexecuted.
---------------------------------------------------------------------------

    \10\ See Rule 1.5(a).
---------------------------------------------------------------------------

    Proposed Rule 5.35(c) describes how exposed orders are allocated 
following the exposure period.\11\ Any responses priced at the 
prevailing NBBO or better will immediately trade against the order in 
time priority. If during the exposure period the Exchange receives an 
unrelated order (or quote) on the opposite side of the market from the 
exposed order that could trade against the exposed order at the 
prevailing NBBO price or better, then the orders will trade at the 
prevailing NBBO price. The exposure period will not terminate if a 
quantity remains on the exposed order after such trade. Responses that 
are not immediately executable based on the prevailing NBBO may become 
executable during the exposure period based on changes to the NBBO. In 
the event of a change to the NBBO and at the conclusion of the exposure 
period, the Exchange will evaluate remaining responses as well as the 
ABBO and execute any remaining portion of the exposed order to the 
fullest extent possible at the best price(s) by executing against 
responses and unrelated orders (pursuant to the allocation algorithm in 
effect for the class). Following the exposure period, the Exchange will 
route the remaining portion of the exposed order to other exchanges, 
unless otherwise instructed by the User. Any portion of a routed order 
that returns unfilled shall trade against the Exchange's best bid/offer 
unless another exchange is quoting at a better price, in which case new 
orders shall be generated and routed to trade against such better 
prices. All executions on the Exchange pursuant to this paragraph will 
comply with Chapter 5, Section E.\12\
---------------------------------------------------------------------------

    \11\ The Exchange intends to set the length of the exposure 
period to 10 milliseconds for all classes when it activates SUM on 
the Exchange.
    \12\ Chapter 5, Section E incorporates Cboe Options Rules 
regarding the Options Order Protection and Locked/Crossed Market 
Plan (the ``Linkage Plan''), including the order protection 
requirements set forth in Cboe Options Rule 5.66.
---------------------------------------------------------------------------

    Proposed Rule 5.35(d) describes the circumstances under which the 
exposure period terminates prior to its expiration. In addition to the 
receipt of a response or unrelated order or quote to trade the entire 
exposed order at the NBBO or better, the exposure period also 
terminates prior to its expiration, and the System processes the 
exposed order in accordance with proposed paragraph (c), if during the 
exposure period (1) the NBBO updates such that the exposed order is no 
longer marketable against the prevailing NBBO; or (2) the Exchange is 
displaying an

[[Page 56516]]

unrelated order on the same side of the market as the exposed order and 
such displayed order is subsequently locked or crossed by another 
options exchange.
    The purpose of the proposed change is to provide all Users with the 
opportunity to improve their prices and ``step up'' to meet the NBBO in 
order to interact with orders sent to the Exchange. This will allow the 
market participant sending an order to the Exchange to increase its 
chances of receiving an execution at the Exchange (the market 
participant's chosen venue) instead of having the order be routed to 
another exchange. This ``step up'' process allows market participants 
to account for factors beyond just disseminated prices, such as 
execution costs, system reliability, and quality of service, when 
determining the exchange to which to route an order. A market 
participant that prefers the Exchange due to some combination of these 
other factors will know that, even if the Exchange is not displaying a 
price that is the NBBO, the market participant may still receive an 
execution at the Exchange because another User may ``step up'' to match 
the NBBO. Further, SUM and the ``step up'' process enable Users to add 
liquidity that is available to interact with orders sent to the 
Exchange. Indeed, when a User on the Exchange ``steps up'' to match the 
NBBO that is displayed on another exchange, more contracts may be 
executed at this NBBO price on the Exchange than are available at that 
same price on the other exchange.
    In connection with the proposed SUM functionality, the Exchange 
proposes to amend Rule 5.21(b)(2) to indicate that a description of how 
SUM will operate during a limit up-limit down state is described in 
proposed Rule 5.35. Additionally, the Exchange proposes to amend Rule 
5.25(c) (Auction Response Processing) to add a reference to SUM. 
Currently, Rule 5.25(c) provides that at the conclusion of an auction 
response or exposure period, the System will continue to process any 
messages in its inbound queue that were received by the System before 
the end of the auction response or exposure period for up to an 
Exchange-determined period of time on a class-by-class basis, not to 
exceed 100 milliseconds, which shall be announced with reasonable 
advance notice via Exchange Notice. The proposed amendment adds SUM to 
the list of auction mechanisms to which this provision applies, so that 
SUM exposure periods receive the same message processing treatment as 
COA response periods.\13\
---------------------------------------------------------------------------

    \13\ This is similar to Cboe Options Rule 5.25(c).
---------------------------------------------------------------------------

    The Exchange proposes to amend Rule 5.34(c)(4)(B)(i) (Risk Monitor 
Mechanism) to add a reference to SUM auctions. Currently, Rule 
5.34(c)(4)(B)(i) allows a TPH to specify whether volume or executions 
in COAs count toward the TPH's underlying, EFID, or EFID Group limit 
(on both an interval or absolute basis). The proposed amendment adds 
SUM auctions alongside COAs in this provision, so that TPHs have the 
same ability to manage their risk exposure from SUM executions as they 
do for COA executions.\14\
---------------------------------------------------------------------------

    \14\ This is similar to Cboe Options Rule 5.34(c)(4)(B)(i).
---------------------------------------------------------------------------

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.\15\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \16\ 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) \17\ requirement that the rules of an exchange not be 
designed to permit unfair discrimination between customers, issuers, 
brokers, or dealers.

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

    In particular, the Exchange believes the proposed rule change 
promotes just and equitable principles of trade by providing an 
additional mechanism for price improvement on qualifying orders. SUM 
gives market participants the opportunity to compete for order flow at 
improved prices, which benefits investors by increasing the potential 
for executions at the NBBO or better. Specifically, the SUM exposure 
period permits all Users to respond with improved pricing for orders 
that would otherwise be executed at the Exchange's BBO or routed to 
another exchange. By creating a competitive exposure period, SUM 
incentivizes liquidity providers on the Exchange to offer improved 
pricing to retain order flow, which benefits investors through better 
execution quality.
    The Exchange further believes that SUM removes impediments to and 
perfects the mechanism of a free and open market and a national market 
system. SUM complements the national market system framework by 
providing an intermediate step between local execution and intermarket 
routing that may result in price improvement for the entering order. 
Rather than immediately routing an order to an away exchange when the 
Exchange's BBO is not the NBBO, SUM gives Users the opportunity to 
match or improve the NBBO, which may result in a better price for the 
entering order and promotes a more efficient allocation of liquidity 
across the national market system. As noted above, all executions 
resulting from SUM must comply with Chapter 5, Section E, which 
incorporates the intermarket linkage requirements applicable to the 
Exchange, including the Order Protection requirements set forth in 
Chapter 5, Section E of the Rulebook, and thus the Exchange believes 
the proposed rule change is consistent with the national market 
system's intermarket protections. Orders that are not filled through 
SUM are routed to away exchanges displaying better prices, consistent 
with the Exchange's routing obligations. Accordingly, SUM does not 
impose any burden on the ability of other exchanges to compete for 
order flow or execute orders at their displayed prices.
    The Exchange also believes that SUM protects investors and the 
public interest because qualifying orders receive the benefit of a 
competitive exposure period before execution. The one-second maximum 
exposure period provides a meaningful but brief window for price 
improvement without unduly delaying execution. The proposed early 
termination conditions will cause the exposure period to conclude 
promptly when market conditions change, preventing stale exposures that 
could disadvantage the entering order. Additionally, the Exchange 
believes the restriction on initiating a SUM auction when the NBBO is 
crossed will protect investors from execution during periods of 
potential pricing uncertainty. SUM would provide eligible Users on the 
Exchange with the opportunity to improve their prices to match the NBBO 
to interact with orders sent to the Exchange. This will allow the 
market participant sending an order to the Exchange to increase its 
chances of receiving an execution at the Exchange (the market 
participant's chosen venue)

[[Page 56517]]

instead of having the order be routed to another exchange. This ``step 
up'' process allows market participants to account for factors beyond 
just disseminated prices, such as execution costs, system reliability, 
and quality of service, when determining the exchange to which to route 
an order. A market participant that prefers the Exchange due to some 
combination of these other factors will know that, even if the Exchange 
is not displaying a price that is the NBBO, the market participant may 
still receive an execution at the Exchange because another User may 
``step up'' to match the NBBO. Therefore, the fact that SUM allows a 
market participant who elects to send an order to the Exchange to have 
a greater likelihood of achieving execution at this chosen venue 
without the risk of paying a lower price removes an impediment to and 
perfects the mechanism for a free and open national market system. The 
proposed rule change also permits Users to opt out of the step-up 
process, providing market participants with further flexibility to 
control where their orders are executed. For Users that opt out of the 
proposed step-up process, the proposed rule change will have no impact 
on them, and their orders will continue to be handled in the same 
manner as they are today (i.e., they will route away to another 
exchange for execution pursuant to Rule 5.36, subject to User 
instructions). Further, SUM and the ``step up'' process would enable 
Users to add liquidity that is available to interact with orders sent 
to the Exchange. Indeed, when a User ``steps up'' to match the NBBO 
that is displayed on another exchange, more contracts may be executed 
at this NBBO price on the Exchange than are available at that same 
price on the other exchange. This increased liquidity would benefit all 
market participants on the Exchange, and thus would ultimately protect 
investors and the public interest.
    The proposed rule change is substantively the same as the rules of 
other options markets.\18\ Specifically, the proposed SUM auction is 
based on Cboe Options Rule 5.35. The only differences between the 
proposed rule change and the Cboe Options rule are: (1) the proposed 
rule change excludes language from proposed Rule 5.35 regarding all-or-
none (``AON'') orders, which are not available on the Exchange; and (2) 
the proposed rule change permits Users to opt out of SUM auctions, 
which while not in the Cboe Options rules, other auction processes 
permit Users to opt out of those processes.\19\ The proposed opt out 
has no impact on how the proposed step-up process will function and 
merely means the proposed rule change will have no impact on the orders 
of Users that opt out of the functionality. The proposed rule change is 
also substantively the same as the rules of other options 
exchanges.\20\ The Commission has always been clear that honoring 
better prices on other markets can be accomplished by matching those 
better prices. The proposed SUM auction would allow participants on the 
Exchange to do just that.\21\
---------------------------------------------------------------------------

    \18\ See, e.g., Cboe Options Rule 5.35; IEX Rule 22.270; and 
Cboe EDGX Rule 21.18.
    \19\ See, e.g., Rule 5.33(b)(2) (permits Users to opt out of 
complex order auctions).
    \20\ See, e.g., IEX Rule 22.270.
    \21\ For example, in adopting the Order Protection Rule (Rule 
611) under Regulation NMS in 2005, the Commission stated: ``The 
Order Protection Rule generally requires that trading centers match 
the best quoted prices, cancel orders without an execution, or route 
orders to the trading centers quoting the best prices.'' See 
Securities Exchange Act Release No. 51808 (June 9, 2005), 70 FR 
37496 (June 29, 2005), at 37525.
---------------------------------------------------------------------------

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 Act. The Exchange does not 
believe the proposed rule change will impose any burden on intramarket 
competition that is not necessary or appropriate in furtherance of the 
purposes of the Act. While the Exchange determines eligible order size, 
type, and Capacity on a class-by-class basis, this flexibility is 
consistent with the Exchange's existing authority under other rules and 
is exercised uniformly for all similarly situated participants. All 
Users, including Priority Customers, non-Market Maker non-Priority 
Customers, and Market-Makers, may submit responses to the exposure 
message during the exposure period. The proposed step-up process is 
also voluntary, and all Users will have the ability to opt out of the 
process. As a result, for Users that opt out of the proposed step-up 
process, the proposed rule change will have no impact on them, and 
their orders will continue to be handled in the same manner as they are 
today.
    The Exchange does not believe the proposed rule change will impose 
any burden on intermarket competition that is not necessary or 
appropriate in furtherance of the purposes of the Act, because the 
proposed rule change is substantively the same as rules of other 
options exchanges.\22\ The Exchange believes the proposed rule change 
will promote competition because the ``step-up'' feature of the 
proposed auction allows for execution at the NBBO or price improvement. 
When such price improvement is achieved via this ``stepping up'' to 
meet (or beat) the best quoted price at another exchange, market 
participants are able to receive the best quoted price while still 
achieving execution on the Exchange, the exchange to which they elected 
to send their orders.
---------------------------------------------------------------------------

    \22\ See, e.g., Cboe Options Rule; IEX Rule 22.270; and Cboe 
EDGX Rule 21.18.
---------------------------------------------------------------------------

    The Exchange believes that the proposed rule change will relieve 
any burden on, or otherwise promote, competition. By offering SUM, the 
Exchange provides an additional tool for price improvement that is 
available to all market participants. SUM promotes competition among 
liquidity providers by creating a brief window in which they can 
compete to offer improved prices for qualifying orders. This 
competitive dynamic may benefit orders submitted to the Exchange and 
ultimately investors by increasing the likelihood of executions of 
these orders at the NBBO or better. Without SUM, orders on the Exchange 
that could receive price improvement may instead be routed to away 
exchanges without the benefit of a local exposure period, potentially 
reducing the competitive incentives for Exchange participants to 
provide improved pricing.

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 after the date of the filing, or such 
shorter time as the Commission may designate, it has become effective 
pursuant to Section 19(b)(3)(A)(iii) of the Act \23\ and subparagraph 
(f)(6) of Rule 19b-4 thereunder.\24\
---------------------------------------------------------------------------

    \23\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \24\ 17 CFR 240.19b-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.

---------------------------------------------------------------------------

[[Page 56518]]

    A proposed rule change filed under Rule 19b-4(f)(6) \25\ normally 
does not become operative prior to 30 days after the date of the 
filing. However, pursuant to Rule 19b-4(f)(6)(iii),\26\ the Commission 
may designate a shorter time if such action is consistent with the 
protection of investors and the public interest. The Exchange requests 
that the Commission waive the 30-day operative delay so that the 
proposed rule change may become operative immediately upon filing. The 
proposed rule change sets forth rules that are substantially the same 
as the rules of another options exchange.\27\ In addition, waiver of 
the operative delay would permit the Exchange to implement this 
functionality as soon as practical, which in turn could permit 
investors to receive sooner the benefits of the ``step-up'' feature, 
including potential price improvement. Further, the Exchange states 
that waiver of the operative delay is necessary and appropriate for 
competitive purposes given that other exchanges currently offer 
substantially similar functionality. For these reasons, and because the 
proposal raises no new or novel legal or regulatory issues, the 
Commission finds that waiver of the 30-day operative delay is 
consistent with the protection of investors and the public interest. 
Accordingly, the Commission waives the 30-day operative delay and 
designates the proposed rule change to be operative upon filing.\28\

    \26\ 17 CFR 240.19b-4(f)(6)(iii).
    \27\ See, e.g., IEX Rule 22.270. The Exchange's proposed rules 
are also substantially the same as the rules of one of its 
affiliated options exchanges. See Cboe EDGX Rule 21.18.
    \28\ For purposes only of waiving the 30-day operative delay, 
the Commission 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 investors, or 
otherwise in furtherance of the purposes of the Act. If the Commission 
takes such action, the Commission shall institute proceedings to 
determine whether the proposed rule should be approved or disapproved.
