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
    On September 18, 2025, the Commission approved IEX's proposal to 
adopt rules governing the trading of options on the Exchange in a new 
facility called ``IEX Options''; \8\ IEX Options has announced its plan 
to commence trading options on October 2, 2026.\9\ As set forth in the 
IEX Options rules, the System's \10\ acceptance and execution of 
orders, quotes, and bulk messages, as applicable, are subject to the 
price protection mechanisms and risk controls provided to Options 
Members \11\ in Rule 22.250 (Pre-Trade and Activity-Based Risk 
Controls) and Rule 22.260 (Additional Price Protection Mechanisms and 
Risk Controls). In advance of the commencement of trading options, IEX 
now makes this rule change proposal to address internal inconsistencies 
in Rule 22.260. Specifically, as described below, IEX proposes to 
delete Rule 22.260(b) and to expand the types of orders that are not 
subject to Rule 22.260(e). The Exchange has designated this rule change 
as ``non-controversial'' under Section 19(b)(3)(A) of the Act \12\ and 
provided the Commission with the notice required by Rule 19b-4(f)(6) 
thereunder.\13\
---------------------------------------------------------------------------

2025), 90 FR 26865, 26878 (June 24, 2025) (SR-IEX-2025-02) (Notice 
of Filing of Amendment No. 3 to a Proposed Rule Change To Adopt 
Rules To Govern the Trading of Options on the Exchange for a New 
Facility Called IEX Options) (``Options Rule Filing'') and

    \10\ The term ``System'' means the automated trading system used 
by IEX Options for the trading of options contracts, as described in 
Rule 22.100(a). See Rule 17.100.
    \11\ The term ``Options Member'' means a firm, or organization 
that is registered with the Exchange pursuant to Chapter 18 of these 
Rules for purposes of participating in options trading on IEX 
Options as an Options Order Entry Firm, Options Market Maker, or 
Clearing Member. See Rule 17.100.

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

Background
    IEX Options has three Order Types (applicable to orders and 
quotes): Limit orders,\14\ Market orders,\15\ and Attributable 
orders.\16\ Each order and quote must also have a TIF \17\ of either 
IOC \18\ or Day.\19\ Options Members may also include one of three 
optional ``Handling Instructions'' \20\ with their orders and quotes: 
Book only,\21\ Post Only,\22\ and Intermarket Sweep Orders.\23\
---------------------------------------------------------------------------

    \14\ See Rule 22.100(d)(1).
    \15\ See Rule 22.100(d)(2).
    \16\ See Rule 22.100(d)(3).
    \17\ The term ``TIF'' shall mean the period of time that the 
System will hold an order, subject to the restrictions set forth in 
paragraph (l) below with respect to bulk messages, for potential 
execution. A Time-in-Force applied to a bulk message applies to each 
bid and offer within that bulk message. Unless otherwise specified 
in the Exchange Rules or the context indicates otherwise, the 
Exchange determines which of the following Times-in-Force are 
available on a class or system basis. See Rule 22.100(g).
    \18\ ``Immediate Or Cancel'' or ``IOC'' shall mean, for an order 
so designated, an order that is to be executed in whole or in part 
as soon as such order is received. The portion not so executed 
immediately on the Exchange or another options exchange is cancelled 
and is not posted to the IEX Options Book. IOC orders that are not 
designated as Book Only and that cannot be executed in accordance 
with Rule 22.170 on the System when reaching the Exchange will be 
eligible for routing away pursuant to Rule 22.180. Market Makers may 
designate bulk messages as IOC. See Rule 22.100(g)(1).
    \19\ ``Day'' shall mean, for an order so designated, an order to 
buy or sell which, if not executed expires at market close. Market 
Makers may designate bulk messages as Day. See Rule 22.100(g)(2).
    \20\ The term ``Handling Instruction'' means an additional 
instruction a User designates on an order, subject to the 
restrictions set forth in paragraph (l) below with respect to bulk 
messages. A Handling Instruction applied to a bulk message applies 
to each bid and offer within that bulk message. Unless otherwise 
specified in the Exchange Rules or the context indicates otherwise, 
the Exchange determines which of the following Handling Instructions 
are available on a class or system basis. See Rule 22.100(e).
    \21\ ``Book Only'' is a Handling Instruction that an order is to 
be ranked and executed on the Exchange pursuant to Rule 22.170 
(Order Display and Book Processing), or to be repriced or cancelled, 
as appropriate, without routing away to another options exchange. 
See Rule 22.100(e)(1).
    \22\ ``Post Only'' is a Handling Instruction a User may 
designate on an order that is to be ranked and executed on the 
Exchange pursuant to Rule 22.170 (Order Display and Book Processing) 
or cancelled, as appropriate, without routing away to another 
options exchange except that the order will not remove liquidity 
from the IEX Options Book. The System reprices, cancels or rejects 
(in accordance with User Instructions) a bid (offer) designated as 
Post Only with a price that locks or crosses the Exchange's best 
offer (bid). A Market order cannot be designated as Post Only. See 
Rule 22.100(e)(2).
    \23\ ``Intermarket Sweep Orders'' or ``ISO'' are orders that 
have the meaning provided in Rule 28.100 (Definitions). Such orders 
may be executed at one or multiple price levels in the System 
without regard to Protected Quotations at other options exchanges 
(i.e., may trade through such quotations). The Exchange relies on 
the marking of an order as an ISO when handling such order, and 
thus, it is the entering Options Member's responsibility, not the 
Exchange's responsibility, to comply with the requirements relating 
to ISOs. ISOs are not eligible for routing pursuant to Rule 22.180 
(Order Routing). A Market order cannot be designated as an 
Intermarket Sweep Order. Market Makers may not designate bulk 
messages as ISOs. See Rule 22.100(e)(3).
---------------------------------------------------------------------------

    IEX Options rules provide for several price protection mechanisms, 
including Rule 22.260(b) (Market Orders in No-Bid (Offer) Series) and 
Rule 22.260(e) (Drill-Through Protection). The Market Orders in a No-
Bid (Offer) Series rule is designed to protect Market orders from 
executions at potentially erroneous prices, and provides that if the 
System receives a sell Market order in a series after it is open for 
trading with an NBB \24\ of zero and an NBO \25\ less than or equal to 
$0.50, the System will convert the Market order to a Limit order with a 
limit price equal to the minimum trading increment applicable to the 
series and will post the order to the Order Book.\26\ If the System 
receives a sell Market order in a series after it is open for trading 
with an NBB of zero and an NBO greater than $0.50, the System cancels 
or rejects the Market order, except if the sell Market order would be 
subject to the drill-through protection, in which case the order joins 
the ongoing drill-through process.\27\ If the System receives a buy 
Market order in a series after it is open for trading with an NBO of 
zero, the System cancels or rejects the Market order.\28\
---------------------------------------------------------------------------

    \24\ See Rule 17.100.
    \25\ See Rule 17.100.
    \26\ See Rule 22.260(b)(1)(A). Note that following the Opening 
Process, orders and quotes received prior to and not executed in 
full during the Opening Process will be transitioned to the 
continuous Order Book and handled in accordance with existing IEX 
rules, as applicable. The System is considered to have received such 
orders at that time for purposes of the Market Orders in No-Bid 
(Offer) Series rule. See Rule 22.160(d). The Market Orders in No-Bid 
(Offer) Series rule is not applicable to the Opening Process.
    \27\ See Rule 22.260(b)(1)(B).
    \28\ See Rule 22.260(b)(2).

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

[[Page 59826]]

    The Drill-Through Protection rule is designed to prevent an 
aggressively priced order from executing beyond multiple price levels 
by utilizing a series of iterations up to an Exchange-determined 
``buffer amount'' \29\ that caps how far the order can execute, rather 
than immediately sweeping all available liquidity up to its limit 
price, before it stops executing or routing the order.\30\ Bulk 
messages \31\ and ISOs are not eligible for drill-through 
protection.\32\
---------------------------------------------------------------------------

    \29\ IEX Options determines the buffer amount on a class and 
premium basis. See Rule 22.260(e)(1)
    \30\ See generally Rule 22.260(e)(3)(F).
    \31\ See Rule 22.100(l).
    \32\ See Rule 22.260(e)(4).
---------------------------------------------------------------------------

Proposal
A. Deletion of Rule 22.260(b)
    As noted above, IEX Rule 22.260(b) specifies that if the System 
receives a sell Market order in a series after it is open for trading 
with an NBB of zero, if the NBO in the series is less than or equal to 
$0.50, then the System will convert the Market order to a Limit order 
with a limit price equal to the minimum trading increment applicable to 
the series and enter it into the IEX Options Book. However, IEX Market 
orders may only have a TIF of IOC,\33\ which means a Market order that 
is not ``executed immediately on the Exchange or another options 
exchange is cancelled and is not posted to the IEX Options Book.'' \34\ 
Because Market orders either execute or cancel on entry, they cannot be 
converted by the System into a Limit order that is entered into the 
Options Order Book nor could they be subject to an ongoing drill-
through process.
---------------------------------------------------------------------------

    \33\ The Exchange may determine the TIF(s) applicable to each 
order type on a system-wide basis unless otherwise specified in the 
Exchange Rules. See Rule 22.100(g). The Exchange TIF determinations 
are specified in the FIX and binary input specifications and specify 
that Market orders may only have a TIF of IOC. See IEX Options FIX 
Specification, Appendix A, available at <a href="https://www.iex.io/documents/iex-options-fix-specification">https://www.iex.io/documents/iex-options-fix-specification</a> and IEX Binary Options 
Protocol Specification, Appendix A, available at <a href="https://www.iex.io/documents/iex-binary-options-protocol-specification">https://www.iex.io/documents/iex-binary-options-protocol-specification</a>.
    \34\ See supra note 18.
---------------------------------------------------------------------------

    Thus, the provisions in Rule 22.260(b) that refer to converting a 
sell Market order to a limit order or the order being subject to an 
ongoing drill-through process are inapplicable. If a Market order to 
sell is received at a time when the NBB is zero (i.e., there is no 
interest to buy in the series), the Market order will be automatically 
canceled by the System because it would not be executed, pursuant to 
Rule 22.100(g)(1). With respect to a buy Market order received in a 
series after it is open for trading with an NBO of zero (i.e., there is 
no interest to sell in the series), Rule 22.260(b)(2) provides that the 
order will be rejected. In this context the terms rejected and canceled 
achieve the same result because the order would not rest on the IEX 
Options Order Book. Accordingly, IEX proposes to delete Rule 22.260(b) 
as unnecessary and duplicative of Rule 22.100(g)(1) and insert the word 
``Reserved'' in its place.
B. Amendment to Rule 22.260(e)
    IEX's Drill-Through Protection provides execution-price protection 
for liquidity-taking orders, which permits a marketable order to access 
liquidity across multiple price levels while limiting the distance 
through the prevailing contra-side NBBO at which executions may 
initially occur to prevent an order from executing through successive 
price levels too aggressively.\35\
---------------------------------------------------------------------------

    \35\ See generally Rule 22.260(e).
---------------------------------------------------------------------------

    IEX's Drill-Through Protection Rule does not apply to bulk messages 
or ISOs.\36\ Bulk messages are designed to enable Market Makers to 
efficiently submit and update liquidity providing quotations, rather 
than to function as liquidity-taking orders seeking execution through 
multiple price levels. For example, Day \37\ bulk messages cannot sweep 
at all because they are Post Only; \38\ and IOC bulk messages are for 
the limited purpose of Market Maker risk management.\39\ Accordingly, 
applying drill-through to bulk messages would not meaningfully advance 
the purpose for which drill-through protection was designed.
---------------------------------------------------------------------------

    \36\ See Rule 22.260(e)(4).
    \37\ An order or quote with a TIF of Day that does not execute 
on entry rests on the Order Book, and if it does not execute before 
market close, is canceled. See Rule 22.100(g)(2).
    \38\ See Rule 22.100(l)(3).
    \39\ See Securities Exchange Act Release No. 105729 (June 18, 
2026), 91 FR 38051 (June 24, 2026) (SR-IEX-2026-17) (Allowing bulk 
messages to have a TIF of IOC for the limited purpose of Market 
Maker risk management, in view of a Market Maker's core obligation 
to provide liquidity to the market.)
---------------------------------------------------------------------------

    IEX's Drill-Through Protection Rule does not apply to ISOs for a 
different reason. An Options Member submitting an ISO order is 
affirmatively instructing the Exchange to execute the order through the 
market up to its limit price without regard to Protected Quotations at 
other options exchanges.\40\ Restricting the order by the Drill-Through 
process would be inconsistent with the objective of an ISO order.
---------------------------------------------------------------------------

    \40\ See supra note 23,
---------------------------------------------------------------------------

    IEX proposes to exclude Post Only orders (i.e., including orders 
and quotes not submitted as bulk messages), which by definition cannot 
remove liquidity from the IEX Options Order Book, from the Drill-
Through Protection rule. For the reasons discussed above, this 
exclusion is logical because Drill-Through Protection is designed to 
protect liquidity-taking orders (something Post Only orders cannot do) 
from executing at too aggressive a price.\41\ Thus, as proposed, Rule 
22.260(e)(3)(4) will now read: ``This protection does not apply to bulk 
messages, Post Only, or ISOs.''
---------------------------------------------------------------------------

    \41\ IEX Options rules provide that the System reprices, 
cancels, or rejects Post Only interest that would lock/cross the 
Exchange's contra-side interest, and Post Only interest does not 
route away. See supra note 22.
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent 
with Section 6(b) of the Act \42\ in general, and furthers the 
objectives of Section 6(b)(5) of the Act \43\ 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 mechanism of a free and open market and a national market 
system, and, in general, to protect investors and the public interest.
---------------------------------------------------------------------------

    \42\ 15 U.S.C. 78f(b).
    \43\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    As discussed in the Purpose section, the proposed rule change is 
designed to address internal inconsistencies in IEX Options rules. As 
such, the proposed rule change would foster cooperation and 
coordination with persons engaged in facilitating transactions in 
securities and would remove impediments to and perfect the mechanism of 
a free and open market and a national market system.
    In particular, the Exchange believes the proposed rule change will 
promote just and equitable principles of trade, remove impediments to 
and perfect the mechanism of a national market system, and protect 
investors and the public interest, by clarifying how impacted order 
types will function. Specifically, IEX believes that Options Members 
would not expect a Market order with a TIF of IOC to be eligible for 
the Market Orders in No-Bid (Offer) Series protection of converting the 
order to a Limit order and would not expect Drill-Through Protection 
for aggressive taking orders to apply to Post Only orders that by 
definition must add liquidity to the Order Book. Thus, IEX believes 
that the proposed changes will reduce confusion

[[Page 59827]]

among market participants, thereby removing impediments to and 
perfecting the mechanism of a free and open market and a national 
market system, and, in general, protecting investors and the public 
interest.
    The Exchange also believes that the proposed changes are consistent 
with the investor protection and the public interest provisions of the 
Act because impacted order types will continue to function as expected. 
Specifically, buy (or sell) Market orders received in a series after it 
is open for trading with an NBO (or NBB) of zero, will be canceled, 
which is what an Options Member would expect to happen when there is no 
contra-party interest because all IEX Options Market orders have a TIF 
of IOC.\44\ And with respect to Drill-Through Protections, because Post 
Only orders do not take liquidity, it is logical to exclude them from a 
protection mechanism that prevents taking liquidity at excessive 
prices. Importantly, Market orders and Post Only orders will continue 
to be subject to all the applicable protections specified in Rules 
22.250 and 22.260.
---------------------------------------------------------------------------

    \44\ See supra note 33.
---------------------------------------------------------------------------

    Moreover, the Exchange believes these proposed, narrowly tailored 
changes to its rules are not designed to permit unfair discrimination 
among Options Members as they would apply equally to all Options 
Members.
    Finally, each of these proposed changes is based on the logical 
functionality of the Commission-approved price protection mechanisms 
coupled with how IEX's order types, TIFs, and Handling Instructions 
interact, and thus, the Exchange does not believe that the proposed 
rule change raises any new or novel issues.

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 that 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. To the extent 
the proposed changes enhance the competitiveness of IEX Options, 
competing exchanges have and can continue to adopt comparable 
functionality, subject to the Commission's rule filing process.
    The Exchange also does not believe that 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. The rule 
change will apply equally to all Options Members. The Exchange believes 
that these proposed changes to Rule 22.260 to better align the rule 
with System functionality will enable Options Members to better 
understand and utilize these price protection mechanisms and risk 
controls, which, in turn, may enhance the integrity of trading on the 
options market and help to assure the stability of the financial 
system.

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 \45\ and Rule 19b-4(f)(6) \46\ 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 \47\ and Rule 19b-4(f)(6) \48\ thereunder.
---------------------------------------------------------------------------

    \45\ 15 U.S.C. 78s(b)(3)(A).
    \46\ 17 CFR 240.19b-4(f)(6).
    \47\ 15 U.S.C. 78s(b)(3)(A).
    \48\ 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) \49\ normally 
does not become operative prior to 30 days after the date of the 
filing. However, pursuant to Rule 19b-4(f)(6)(iii),\50\ the Commission 
may designate a shorter time if such action is consistent with 
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. According to 
the Exchange, waiving the 30-day delay would allow the proposed rule 
change to become operative on October 2, 2026, when IEX Options 
commences trading, and would permit the IEX Options System to operate 
in a manner fully aligned with IEX Options rules, alleviating any 
confusion among market participants about how the rules operate. Waiver 
of the 30-day operative delay is consistent with the protection of 
investors and the public interest because it allows the revised IEX 
Options rules to be operative by October 2, 2026, the date that trading 
begins on the IEX Options System, provides clarity and prevents 
potential confusion for market participants about the operation of IEX 
Options rules, and does not introduce any novel regulatory issues. 
Accordingly, the Commission designates the proposed rule change to be 
operative upon filing.\51\
---------------------------------------------------------------------------

    \49\ 17 CFR 240.19b-4(f)(6).
    \50\ 17 CFR 240.19b-4(f)(6)(iii).
    \51\ 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 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.

IV. Solicitation of Comments

    Interested persons are invited to submit written data, views and 
arguments concerning the foregoing, including whether the proposed rule 
change is consistent with the Act. Comments may be submitted by any of 
the following methods:
