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
Effective September 1, 2025, IEX proposes to introduce two new
pricing tier levels, Incremental Fee Tier 1 and Incremental Fee Tier 2,
applicable to certain non-displayed trades, which are designed to
incentivize increased non-displayed trading on the Exchange, as
described below.\9\ IEX also proposes to make a non-substantive
formatting change to the Fee Schedule, as discussed below.\10\
---------------------------------------------------------------------------
\9\ Nothing in this rule filing affects trades below $1.00 per
share (``sub-dollar trades''). Sub-dollar trades would not impact
the Incremental Fee Tier calculations and would not be eligible for
any of the Incremental Fee Tiers described herein.
\10\ The Exchange initially filed the proposed Fee Schedule
changes on August 28, 2025 (SR-IEX-2025-23). On September 10, 2025,
the Exchange withdrew that filing and submitted this proposal.
---------------------------------------------------------------------------
As reflected in the Transaction Fees section of the Fee Schedule,
the Exchange currently charges a standard fee of $0.0010 per share for
trades that add or remove non-displayed liquidity from the Exchange.
IEX also allows certain non-displayed orders to execute for free:
Retail \11\ orders that remove liquidity and Retail Liquidity Provider
(``RLP'') \12\ orders, which are resting non-displayed orders that may
only match with incoming Retail orders.\13\
---------------------------------------------------------------------------
\11\ See IEX Rule 11.190(b)(15).
\12\ See IEX Rule 11.190(b)(14).
\13\ IEX is also not proposing to make any changes to the fees
applicable to the execution of Retail or Retail Liquidity Provider
orders, which will continue to execute for free.
---------------------------------------------------------------------------
In order to further incentivize non-displayed trading on the
Exchange, IEX now proposes to adopt a new volume-based fee incentive,
referred to as ``Incremental Fee Tier 2'',\14\ in which IEX will charge
a reduced fee of $0.0001 per share for certain executions of non-
displayed orders \15\ to Members that increase their non-displayed
volume for August 2025 (``the Baseline Month'') by at least 10,000,000
non-displayed volume per day. Given this, the Exchange is also
proposing that the criteria to qualify for Incremental Fee Tier 2 will
expire no later than February 28, 2026, which it will indicate in a
footnote to the proposed Incremental Fee Tiers table on the IEX Fee
Schedule. As part of this proposal, IEX proposes to add two new
definitions under ``Definitions and Information'' in the ``Transaction
Fees'' section of the IEX Fee Schedule. Specifically, IEX proposes to
introduce the terms ``Baseline non-displayed ADV'',\16\ which it
defines as executions with any of the Fee Code Combinations MI, MIB,
TI, TIB, TIY, or TIYB in August 2025, and ``Incremental non-displayed
ADV'', which it defines as executions with any of the Fee Code
Combinations MI, MIB, TI, TIB, TIY, or TIYB that exceed the Baseline
non-displayed ADV. To qualify for Incremental Fee Tier 2, a Member's
Incremental non-displayed ADV must be at least 10,000,000.\17\
---------------------------------------------------------------------------
\14\ While IEX is proposing to introduce two Incremental Fee
Tiers, Incremental Fee Tier 2 is the tier that contains the pricing
incentive described in this filing; any Members that do not qualify
for Incremental Fee Tier 2 will qualify for Incremental Fee Tier 1,
which applies the same fees to non-displayed liquidity adding or
removing trades as those currently charged by the Exchange. See
infra note 17.
\15\ The fee codes to which the Incremental Fee Tiers would
apply are ``MI'' (Adds non-displayed liquidity); ``MIB'' (Adds non-
displayed liquidity in Tape B securities); ``TIY'' (Post Only order
removes non-displayed liquidity); ``TIYB'' (Post Only order removes
non-displayed liquidity in Tape B securities); ``TI'' (Removes non-
displayed liquidity); and ``TIB'' (Removes non-displayed liquidity
in Tape B securities).
\16\ The Fee Schedule defines ``ADV'' as the number of shares
added or removed that execute at or above $1.00 per share, combined,
per day, calculated on a monthly basis.
\17\ IEX also proposes to introduce Incremental Fee Tier 1,
which will apply to any Member that does not qualify for Incremental
Fee Tier 2 (i.e., a Member with an Incremental non-displayed ADV
that is less than 10,000,000). The fees associated with Incremental
Fee Tier 1 will be the same as the current fees for non-displayed
liquidity adding or removing trades.
---------------------------------------------------------------------------
The reduced fee of $0.0001 per share for Incremental non-displayed
ADV in excess of the Baseline non-displayed ADV will be capped at a
Member's Baseline non-displayed ADV, and any additional volume will be
charged the regular fee of $0.0010 per share for either adding or
removing non-displayed liquidity. By way of example, if a Member's
Baseline non-displayed ADV is 15,000,000, and its non-displayed volume
for September 2025 is 35,000,000, then the Member's Incremental non-
displayed ADV would be 20,000,000 for September 2025. However, for that
month, the Member would only receive the reduced $0.0001 fee for
15,000,000 of its Incremental non-displayed ADV and would pay the
regular fee of $0.0010 for 20,000,000 of its non-displayed volume. If
that same Member had 10,000,000 Baseline non-displayed ADV and
10,000,000 Incremental non-displayed ADV in September 2025, for that
month, it would pay $0.0001 for its Incremental non-displayed ADV and
$0.0010 for 10,000,000 of its non-displayed volume (the same amount as
its Baseline non-displayed ADV).
Accordingly, IEX proposes to update its Fee Schedule to make
several revisions to reflect the proposed new Incremental Fee Tiers.
First, the Exchange proposes to introduce the aforementioned
definitions of ``Baseline non-displayed ADV'' and ``Incremental non-
displayed ADV'' as part of the ``ADV'' definition in the Definitions
and Information section of the Transaction Fees section of the Fee
Schedule.
IEX also proposes to add Footnote 6 to the Transaction Fees section
of the Fee Schedule, and to append it to the following Fee Code
Combinations: MI, MIB, TIY, TIYB, TI, and TIB in the Fee Code
Combinations and Associated Fees table.
As proposed, Footnote 6 will be titled ``Incremental Fee Tiers
(Applicable to Executions at or above $1)'' and followed by a table
describing Tier 1 and Tier 2, including the required criteria for each
tier and the applicable fee, as described above. This table will have
two fee columns, the first column showing the ``Fee for Baseline non-
displayed ADV'' and the second column the ``Fee for Incremental non-
displayed ADV.'' As described above, only transactions representing
non-displayed volume of a Member that is sufficiently greater than the
Baseline non-displayed ADV of that Member will receive the discounted
$0.0001 per share fee. To clarify how the fee works, IEX also proposes
to include a new footnote ``a'' to the table which reads:
This fee is only applicable to Incremental non-displayed ADV
that does not exceed the Baseline non-displayed ADV. For example, if
a Member's Baseline non-displayed ADV is 15,000,000 and its
Incremental non-displayed ADV is 20,000,000 (resulting in a total of
35,000,000 daily non-displayed shares traded), the Member qualifies
for Tier 2 (because its Incremental non-displayed ADV of 20,000,000
is >=10,000,000), but the $0.0001 fee is only applicable to
15,000,000 of the Incremental non-displayed ADV because the reduced
fee is capped at the Baseline non-displayed ADV. Therefore, the
Member would be charged $0.0010 on 20,000,000 and $0.0001 on
15,000,000 daily
[[Page 45073]]
non-displayed shares traded. Additionally, IEX notes that the above
criteria to qualify for Incremental Fee Tier 2 will expire no later
than February 28, 2026.
IEX designed the Incremental Fee Tiers to offer Members a means of
receiving discounted fees for executions that are currently charged
$0.0010 per share \18\ by sufficiently increasing their non-displayed
trading activity on IEX when compared to the Baseline Month (August
2025). Therefore, IEX believes it is reasonable to only include in the
Incremental Fee Tiers executions with the Fee Code Combinations MI,
MIB, TI, TIB, TIY, or TIYB.
---------------------------------------------------------------------------
\18\ Specifically non-displayed liquidity adding and removing
transactions.
---------------------------------------------------------------------------
The goal of the Incremental Fee Tiers is to incentivize members to
increase the orders sent directly to IEX and therefore provide
liquidity to the benefit of all market participants. These Tiers would
be expected to benefit Members whose increased order flow provides
added levels of liquidity. Additionally, a previous month baseline
approach for rebates and fees has also been adopted by several other
exchanges, including NYSE Arca \19\ and Cboe EDGX.\20\
---------------------------------------------------------------------------
\19\ See Securities Exchange Act Release No. 64820 (July 6,
2011), 76 FR 40974 (July 12, 2011) (SR-NYSEArca-2011-41) (filing to
introduce step up tiers).
\20\ See Securities Exchange Act Release No. 80034 (February 14,
2017), 82 FR 11275 (February 21, 2017) (SR-BatsEDGX-2017-09) (filing
to introduce step up tiers).
---------------------------------------------------------------------------
Additionally, IEX proposes to make a non-substantive formatting
change to its Fee Schedule. Currently, there is no punctuation
separating Fee Code Combinations with multiple footnotes. For example,
Fee Code Combination TLB (Removes displayed liquidity (Tape B)) is
modified by footnotes 2 and 5, but without a separating comma, it could
read that it is modified by footnote 25 (although there is no footnote
25 on the Fee Schedule). Thus, IEX proposes to add a comma between any
two footnotes to clarify the footnote's number.
As noted above, the Exchange is not proposing to change the fees
applicable to executions of and with orders with an execution price
below $1.00 per share, or to the fees applicable to the execution of
Retail and RLP orders, which will continue to execute for free.
2. Statutory Basis
IEX believes that the proposed rule change is consistent with the
provisions of Section 6(b) \21\ of the Act in general and furthers the
objectives of Sections 6(b)(4) \22\ of the Act, in particular, in that
it is designed to not be unfairly discriminatory and to provide for the
equitable allocation of reasonable dues, fees and other charges among
its Members and other persons using its facilities. The Exchange
believes that the proposal does not constitute an inequitable
allocation of fees, as all Members will be equally eligible to increase
their non-displayed volume over their August 2025 non-displayed volume
by at least 10,000,000, and access to the Exchange's market is offered
on fair and non-discriminatory terms. IEX notes that even if a Member
is unable to directly qualify for Incremental Fee Tier 2, that Member
can aggregate its non-displayed volume on IEX by, for example, using
another Member for direct market access. Thus, all Members have a
reasonable path to qualifying for Incremental Fee Tier 2. Thus, IEX
believes that the proposal is not designed to permit unfair
discrimination.
---------------------------------------------------------------------------
\21\ 15 U.S.C. 78f.
\22\ 15 U.S.C. 78f(b)(4).
---------------------------------------------------------------------------
IEX believes the Incremental Fee Tiers are not unfairly
discriminatory because they provide equal incentives to all Members to
increase their non-displayed volume over their August 2025 non-
displayed volume. In particular, the number of a Member's shares
eligible for the discounted fee of Incremental Fee Tier 2 is tied to
the level of that Member's trading activity, and has no relationship to
any differences between types of Members.
IEX also believes that it is reasonable and equitable to cap the
volume of a Member's Incremental non-displayed ADV that will be charged
the discounted fee of $0.0001 at the volume of a Member's Baseline non-
displayed ADV. By design, the amount of a Member's volume that may
benefit from the new fee incentive must be reasonably related to the
volume a Member traded on IEX in the past. Thus, this proposal is
consistent with the Exchange Act because it is designed to equitably
reward Members for the incremental increased volume they bring to the
Exchange. For example, a Member with a Baseline non-displayed ADV of
5,000,000 would not be able to execute 20,000,000 Incremental non-
displayed ADV in September 2025 and expect to pay only $0.0001 for all
Incremental non-displayed ADV in excess of its 5,000,000 Baseline non-
displayed ADV. As discussed in the Purpose section, this Member would
pay $0.0001 for its Incremental non-displayed ADV of 5,000,000 and pay
$0.0010 for its remaining non-displayed volume of 20,000,000.
The Exchange operates in a highly competitive market in which
market participants can readily direct order flow to competing venues
if they deem fee levels at a particular venue to be excessive. IEX has
concluded that, in the context of current regulatory requirements
governing access fees and rebates, it is able to more effectively
compete with other exchanges for order flow by offering Members an
additional means of qualifying for stronger fee or rebate incentives.
Based upon informal discussions with market participants, IEX believes
that Members and other market participants may be more willing to send
more non-displayed orders to IEX if the proposed fee change is adopted.
The Exchange also believes that adding definitions of ``Baseline
non-displayed ADV'' and ``Incremental non-displayed ADV'' to the Fee
Schedule, and inserting commas any place there are two or more
footnotes applied to a Fee Code Combination are reasonable, equitable,
and non-discriminatory updates to the Fee Schedule because this
language is designed to ensure that the Fee Schedule is as clear and
easily understandable as possible with respect to the criteria applied
by the Exchange for the proposed new fee tiers.
Thus, as discussed in the Purpose section, the Exchange believes
that the proposed addition of a volume-based fee tier that charges a
discounted fee to Members who add sufficiently more non-displayed
volume to the Exchange (compared to their non-displayed volume for
August 2025) is reasonable and consistent with the Act because it is
open to all Members on an equal basis and provides fee incentives that
are reasonably related to the value of an exchange's liquidity
associated with higher volumes. As stated above, IEX believes the
Incremental Fee Tiers may incentivize Members to increase non-displayed
trading activity on the Exchange, to the benefit of all market
participants.
IEX notes, as with all tiered pricing structures, that a Member's
volume may include orders from multiple of its customers which would be
aggregated for purposes of determining whether the Member qualifies for
Tier 2 pricing. However, IEX notes that it bills Members at month end
based on the total fees applicable to its trades on IEX, not on a
trade-by-trade basis. Depending on its billing arrangements with its
customers, Members would thus be able to utilize a blended fee rate for
such billing purposes. IEX believes that tiered pricing structures are
well understood by brokers which enables them to implement appropriate
billing processes. Accordingly, IEX believes that the proposed fee
structure is not designed to permit unfair discrimination among a
Member's customers and is consistent with the
[[Page 45074]]
Act. Moreover, IEX notes (as discussed above) that the proposed fee
structure is designed to incentivize additional non-displayed liquidity
which benefits all Members and their customers.
As noted in the Purpose section, other exchanges offer rebate and
fee tiers based on a comparison of current month trading activity to
the trading activity of a prior, baseline month, and thus the Exchange
does not believe that this aspect of the proposal raises any new or
novel issues not already considered by the Commission.
As discussed above, the Exchange operates in a highly competitive
market in which market participants can readily direct order flow to
competing venues if they deem fee levels at a particular venue to be
excessive. Within that context, the proposed Incremental Fee Tier
structure is designed to keep IEX's non-displayed trading prices
competitive with those of other exchanges.
Further, IEX believes that it is reasonable and consistent with the
Act not to change the fees applicable to the execution of Retail orders
that remove liquidity and RLP orders that provide liquidity to Retail
orders, both of which will continue to execute for free. In this
regard, the Exchange believes that the existing fee structure continues
to be reasonably designed to incentivize the entry of Retail orders,
and notes that the Commission, in approving IEX's Retail Price
Improvement Program, acknowledged the value of exchanges' offering
incentives to attract both retail investor orders and orders
specifically designated to execute only with retail orders.\23\
---------------------------------------------------------------------------
\23\ See Securities Exchange Act Release No. 86619 (August 9,
2019), 84 FR 41769, 41771 (August 15, 2019) (SR-IEX-2019-05).
---------------------------------------------------------------------------
Finally, to the extent this proposed fee change is successful in
incentivizing the entry and execution of more non-displayed orders on
IEX, such greater liquidity will benefit all market participants by
increasing execution opportunities. And, as discussed above, IEX does
not believe that any aspect of this proposal raises new or novel issues
not already considered by the Commission.
B. Self-Regulatory Organization's Statement on Burden on Competition
IEX does not believe that the proposed rule change will result in
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. The Exchange operates in a highly competitive
market in which market participants can readily direct order flow to
competing venues if fee schedules at other venues are viewed as more
favorable. Consequently, the Exchange believes that the degree to which
IEX fees could impose any burden on competition is extremely limited
and does not believe that such fees would burden competition between
Members or competing venues. Moreover, as noted in the Statutory Basis
section, the Exchange does not believe that the proposed changes raise
any new or novel issues not already considered by the Commission.
The Exchange 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 because, while
different rebates and fees are assessed on Members, these rebate and
fee tiers are not based on the type of Member entering the orders that
match, but rather on the Member's own trading activity. Further, the
proposed fee changes continue to be intended to encourage market
participants to bring increased order flow to the Exchange, which
benefits all market participants.
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 foregoing rule change has become effective pursuant to Section
19(b)(3)(A)(ii) \24\ of the Act.
---------------------------------------------------------------------------
\24\ 15 U.S.C. 78s(b)(3)(A)(ii).
---------------------------------------------------------------------------
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 under
Section 19(b)(2)(B) \25\ of the Act to determine whether the proposed
rule change should be approved or disapproved.
---------------------------------------------------------------------------
\25\ 15 U.S.C. 78s(b)(2)(B).
