[Release No. 34-103643; File No. SR-ISE-2025-22]


Self-Regulatory Organizations; Nasdaq ISE, LLC; Notice of Filing 
and Immediate Effectiveness of Proposed Rule Change To Amend FLEX, 
Position and Exercise Limit Rules for the Grayscale Bitcoin Mini Trust 
ETF, the Bitwise Bitcoin ETF, and the Grayscale Bitcoin Trust ETF

August 5, 2025.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given that 
on July 31, 2025, Nasdaq ISE, LLC (``ISE'' or ``Exchange'') filed with 
the Securities and Exchange Commission (``Commission'') the proposed 
rule change as described in Items I and II below, which Items have been 
prepared by the Exchange. The Commission is publishing this notice to 
solicit comments on the proposed rule change from interested persons.
---------------------------------------------------------------------------

    \1\ 15 U.S.C. 78s(b)(1).
    \2\ 17 CFR 240.19b-4.
---------------------------------------------------------------------------

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

    The Exchange proposes to amend Options 3A, Section 3, FLEX Option 
Listings; Options 3A, Section 18, Position Limits; Options 9, Section 
13, Position Limits; and Options 9, Section 15, Exercise Limits, with 
respect to options on the Grayscale Bitcoin Mini Trust ETF (``BTC''), 
the Bitwise Bitcoin ETF (``BITB'') and the Grayscale Bitcoin Trust ETF 
(``GBTC'').
    The text of the proposed rule change is available on the Exchange's 
website at https://listingcenter.nasdaq.com/rulebook/ise/rulefilings 
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 Options 3A, Section 3, FLEX Option 
Listings; Options 3A, Section 18, Position Limits; Options 9, Section 
13, Position Limits; and Options 9, Section 15, Exercise Limits with 
respect to options on the Grayscale Bitcoin Mini Trust ETF (``BTC''), 
the Bitwise Bitcoin ETF (``BITB'') and the Grayscale Bitcoin Trust ETF 
(``GBTC''). Each change will be described below.
Position Limits
    Recently, NYSE Arca, Inc. (``Arca'') received approval to eliminate 
the current 25,000 contract position and exercise limit for options on 
BTC and BITB.\3\ As a result, Arca would apply the position limits as 
determined by Arca Rule 6.8-O, Commentary .06(a)-(e) to options on BTC 
and BITB. Additionally, Arca recently received approval to eliminate 
the current 25,000 contract position and exercise limit for options on 
GBTC.\4\ As a result, Arca would apply the position limits as 
determined by Arca Rule 6.8-O, Commentary .06(a)-(e) to options on 
GBTC.
---------------------------------------------------------------------------

    \3\ See Securities Exchange Act Release No. 103568 (July 29, 
2025) (SR-NYSEArca-2025-10) (not yet noticed).
    \4\ See Securities Exchange Act Release No. 103567 (July 29, 
2025) (SR-NYSEArca-2025-07) (not yet noticed).
---------------------------------------------------------------------------

    The Exchange proposes to similarly amend its position limit rules 
at ISE Options 9, Section 13 and exercise limit rules at ISE Options 9, 
Section 15 to likewise eliminate the current 25,000 contract position 
and exercise limit for options on BTC, BITB and GTBC. As a result, BTC, 
BITB and GTBC would be subject to the position limits described in ISE 
Options 9, Section 13 which provides that the position limits for 
equity options are 25,000 or 50,000 or 75,000 or 200,000 or 250,000 
option contracts (with adjustments for splits, re-capitalizations, 
etc.) on the same side of the market or such other number of option 
contracts as may be fixed from time to time by the Exchange. Further, 
ISE Options 9, Section 13(d) describes how the Exchange determines 
which of the five position limit amounts will apply to an equity option 
class (i.e., the position limit applicable to a class is determined 
based on the trading volume and outstanding shares of the underlying 
security).
BTC and BITB
    On October 18, 2024, the Commission approved the listing and 
trading of BTC and BITB on Arca.\5\ On November 22, 2024, Arca obtained 
rule authority to trade options on BTC and BITB.\6\ The current 
position and exercise limits for BTC and BITB options are 25,000 
contracts on ISE, the lowest limit available in options.\7\ Arca 
proposed to effectively increase the aggregated position and exercise 
limits for each ETF to 250,000 contracts. Arca noted that BTC and BITB 
currently qualify for this increased limit pursuant to Arca Rule 6.8-O 
Commentary .06(e), which requires that, for the most recent six-month 
period, trading volume for the underlying security is at least 
100,000,000 shares.\8\ Arca noted that, as of November 25, 2024, during 
the most recent six-month period, trading volume for BTC was 
163,712,700 shares. Arca noted that during the same period, trading 
volume for BITB was 288,800,860 shares. In addition, Arca noted that, 
as of November 25, 2024, the market capitalization for BTC was 
$3,496,748,882 \9\ with an average daily volume (``ADV'') for the 
preceding three months of 2,036,369 shares, and the market 
capitalization of BITB was 4,095,157,000 \10\ with an ADV for the three 
prior months of 2,480.478. BTC and BITB are well above the requisite 
minimum of 100,000,000 shares necessary to qualify for the 250,000 
contract position and exercise limit. Also, Arca noted that, as of 
November

[[Page 38530]]

25, 2024, there were 19,787,762 bitcoins in circulation.\11\ At a price 
of $94,830 per bitcoin,\12\ that equates to a market capitalization of 
greater than $1.876 trillion. Arca noted that if a position limit of 
250,000 contracts were considered for each ETF, the exercisable risk 
would represent 30.14% \13\ of BTC shares outstanding; and 31.27% \14\ 
of BITB shares outstanding. Given the liquidity of BTC and BITB, the 
current 25,000 position limit appears extremely conservative.
---------------------------------------------------------------------------

    \5\ See Securities Exchange Act Release No. 101386 (October 18, 
2024), 89 FR 84960 (October 24, 2024) (SR-NYSEAMER-2024-49) (order 
approving rules to permit the listing and trading of options on BTC 
and BITB, among others) (the ``ETF Options Approval Order'').
    \6\ See Securities Exchange Act Release No. 101713 (November 22, 
2024), 89 FR 94839 (November 29, 2024) (SR-NYSEARCA-2024-101) 
(notice of immediately effective rule change to permit BTC and BITB 
options trading, based on the already-approved NYSE American rules) 
(the ``Arca ETF Options Notice'').
    \7\ See ISE Options 9, Section 13.
    \8\ See Arca Rule 6.8-O Commentary .06(e) (providing at 
subparagraph (e) that the position limit shall be 250,000 contracts 
for options: (i) on underlying stock or Exchange-Traded Fund Share 
that had trading volume of at least 100,000,000 shares during the 
most recent six-month trading period; or (ii) on an underlying stock 
or Exchange-Traded Fund Share that had trading volume of at least 
75,000,000 shares during the most recent six-month trading period 
and has at least 300,000,000 shares currently outstanding).
    \9\ The market capitalization of BTC was determined by 
multiplying a settlement price ($42.16) by the number of shares 
outstanding (82,939,964). Data represents figures from FactSet as of 
November 25, 2024.
    \10\ The market capitalization of BITB was determined by 
multiplying a settlement price ($51.70) by the number of shares 
outstanding (79,950,100). Data represents figures from FactSet as of 
November 25, 2024.
    \11\ See https://www.coingecko.com/en/coins/bitcoin.
    \12\ This is the approximate price of bitcoin from 4:00 p.m. ET 
on November 25, 2024.
    \13\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/82,939,964 BTC shares 
outstanding).
    \14\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/79,950,100 BITB shares 
outstanding).
---------------------------------------------------------------------------

    First, Arca reviewed the ETFs' data relative to the market 
capitalization of the entire bitcoin market in terms of exercise risk 
and availability of deliverables. Arca noted that, as noted above, as 
of November 25, 2024, there were 19,787,762 bitcoins in 
circulation.\15\ At a price of $94,830 per bitcoin,\16\ that equates to 
a market capitalization of greater than $1.876 trillion. Arca noted 
that if the proposed aggregated position limit of 250,000 contracts 
were considered, the exercisable risk would represent 30.14% of BTC 
shares outstanding \17\ and 31.27% of BITB shares outstanding.\18\ Arca 
noted that since each ETF has a creation and redemption process managed 
through the issuer (whereby bitcoin is used to create BTC or BITB 
shares, as applicable), the position limit can be compared to the total 
market capitalization of the entire bitcoin market, and in that case, 
the exercisable risk for options on each ETF would represent less than 
0.06% (BTC) or 0.07% (BITB) of all bitcoin outstanding.\19\
---------------------------------------------------------------------------

    \15\ See https://www.coingecko.com/en/coins/bitcoin.
    \16\ This is the approximate price of bitcoin from 4:00 p.m. ET 
on November 25, 2024.
    \17\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/82,939,964 BTC shares 
outstanding).
    \18\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/79,950,100 BITB shares 
outstanding).
    \19\ For BTC, this number was arrived at with this calculation: 
((250,000 limit * 100 shares per option * $42.16 settle)/(19,787,762 
bitcoin outstanding * $94,830 bitcoin price)); and for BITB, this 
number was arrived at with this calculation: ((250,000 limit * 100 
shares per option * $51.70 settle)/(19,787,762 bitcoin outstanding * 
$94,830 bitcoin price)).
---------------------------------------------------------------------------

    Next, Arca reviewed the proposed position limit by comparing it to 
position limits for derivative products regulated by the CFTC. While 
the CFTC, through the relevant Designated Contract Markets, only 
regulates options positions based upon delta equivalents (creating a 
less stringent standard), the Exchange examined equivalent bitcoin 
futures position limits. In particular, the Exchange looked to the CME 
bitcoin futures contract \20\ that has a position limit of 8,000 
futures. Arca noted that, on October 22, 2024, CME bitcoin futures 
settled at $94,945.\21\ Arca noted that, on October 22, 2024, BTC 
settled at $29.90, and BITB settled at $36.74, which would equate to 
approximately 31,754,181 and 25,842,406 shares of BTC and BITB, 
respectively, if the CME notional position limit was utilized. Since 
substantial portions of any distributed options portfolio are likely to 
be out of the money on expiration, an options position limit equivalent 
to the CME position limit for bitcoin futures (considering that all 
options deltas are <=1.00) should be a bit higher than the CME implied 
limit of 317,541 (BTC) and 258,424 (BITB).
---------------------------------------------------------------------------

    \20\ CME Bitcoin Futures are described in Chapter 350 of CME's 
Rulebook.
    \21\ See the Position Accountability and Reportable Level Table 
in the Interpretations & Special Notices Section of Chapter 5 of 
CME's Rulebook.
---------------------------------------------------------------------------

    Of note, unlike options contracts, CME position limits are 
calculated on a net futures-equivalent basis by contract and include 
contracts that aggregate into one or more base contracts according to 
an aggregation ratio(s).\22\ Therefore, if a portfolio includes 
positions in options on futures, CME would aggregate those positions 
into the underlying futures contracts in accordance with a table 
published by CME on a delta equivalent value for the relevant spot 
month, subsequent spot month, single month and all month position 
limits.\23\ If a position exceeds position limits because of an option 
assignment, CME permits market participants to liquidate the excess 
position within one business day without being considered in violation 
of its rules. Additionally, if at the close of trading, a position that 
includes options exceeds position limits for futures contracts, when 
evaluated using the delta factors as of that day's close of trading but 
does not exceed the limits when evaluated using the previous day's 
delta factors, then the position shall not constitute a position limit 
violation. Considering CME's position limits on bitcoin futures, the 
Exchange believes a 250,000-contract limit for options on each ETF 
would be appropriate.
---------------------------------------------------------------------------

    \22\ See https://www.cmegroup.com/education/courses/market-regulation/position-limits/positionlimits-aggregation-of-contracts-and-table.htm.
    \23\ See id.
---------------------------------------------------------------------------

    Finally, Arca analyzed a position and exercise limit of 250,000 for 
BTC and BITB against other options on commodity ETFs, namely SPDR Gold 
Shares (``GLD'') and iShares Silver Trust (``SLV'').\24\ GLD has a 
float of 306.1 million shares and a position limit of 250,000 
contract.\25\ As previously noted, position and exercise limits are 
designed to limit the number of options contracts traded on the 
exchange in an underlying security that an investor, acting alone or in 
concert with others directly or indirectly, may control. A position 
limit exercise in GLD would represent 8.17% of the float of GLD. In 
comparison, a 250,000-contract position limit in each of BTC and BITB, 
would represent 30.14% of the BTC float and 31.27% of the BITB float. 
While less conservative than the standard applied to options on GLD, 
the Exchange nonetheless believes that subjecting options on BTC and 
BITB to a 250,000 contract position and exercise limit would be 
appropriate.\26\
---------------------------------------------------------------------------

    \24\ Like BTC and BITB, GLD and SLV each hold one asset in 
trust.
    \25\ See https://www.ssga.com/us/en/intermediary/etfs/spdr-gold-shares-gld.
    \26\ See, e.g., ISE Options 9, Section 13(d) (setting forth 
trading volume requirements to qualify for a 250,000 contract 
position (and exercise) limit.
---------------------------------------------------------------------------

    Based on the foregoing, the Exchange believes that BTC and BITB 
each have more than sufficient liquidity to garner an increased 
position and exercise limit of 250,000 same-side contracts pursuant to 
Options 9, Sections 13 and 15. The Exchange believes that the 
significant liquidity present in each ETF mitigates against the 
potential for manipulation.
    The Exchange believes that allowing options on each ETF to have 
increased aggregated position and exercise limits would lead to a more 
liquid and competitive market environment for such options, which will 
benefit customers that trade these options. Further, the reporting 
requirement for such options would remain unchanged. Thus, the Exchange 
will still require that each member that maintains positions in options 
on BTC or BITB, on the same side of the market, for its own account or 
for the account of a customer, report certain information to the 
Exchange. This information includes, but would not be limited to, the 
options positions, whether such positions are hedged and, if so, a 
description of the hedge(s). Market Makers \27\ would continue to be 
exempt from this reporting requirement,

[[Page 38531]]

however, the Exchange may access Market Maker position information.\28\ 
Moreover, the Exchange's requirement that members file reports with the 
Exchange for any customer who held aggregate large long or short 
positions on the same side of the market of 200 or more option 
contracts of any single class for the previous day will remain at this 
level.\29\
---------------------------------------------------------------------------

    \27\ The term ``Market Makers'' refers to ``Competitive Market 
Makers'' and ``Primary Market Makers'' collectively. See ISE Options 
1, Section 1(a)(21).
    \28\ OCC through the Large Option Position Reporting (``LOPR'') 
system acts as a centralized service provider for Member compliance 
with position reporting requirements by collecting data from each 
Member, consolidating the information, and ultimately providing 
detailed listings of each Member's report to the Exchange, as well 
as FINRA, acting as its agent pursuant to a regulatory services 
agreement (``RSA'').
    \29\ See ISE Options 9, Section 16.
---------------------------------------------------------------------------

GBTC
    On October 18, 2024, the Commission approved the listing and 
trading of GBTC options on Arca.\30\ On November 22, 2024, Arca rule 
authority to trade GBTC options with a 25,000 contract position limit, 
the lowest limit available in options.\31\ Arca noted that GBTC 
currently qualifies for a 250,000-limit on same-side contracts pursuant 
to Arca Rule 6.8-O Commentary .06(e)(i), which requires that trading 
volume for the underlying security in the most recent six months be at 
least 100,000,000 shares.\32\ Arca noted that, as of November 25, 2024, 
during the most recent six-month period, trading volume for GBTC was 
550,687,400 shares. In addition, Arca noted that, as of November 25, 
2024, the market capitalization for GBTC was $20,661,316,542,\33\ with 
an average daily volume (``ADV'') for the preceding three months of 
3,829,597 shares. GBTC is well above the requisite minimum of 
100,000,000 shares necessary to qualify for the 250,000-contract 
position and exercise limit. Also, Arca noted that, as of November 25, 
2024, there were 19,787,762 bitcoins in circulation.\34\ At a price of 
$94,830 per bitcoin,\35\ that equates to a market capitalization of 
greater than $1.876 trillion. If an aggregated position and exercise 
limit of 250,000 contracts were considered, the exercisable risk would 
represent 9.13% \36\ of GBTC shares outstanding. Given GBTC's 
liquidity, the current 25,000-contract position (and exercise) limit is 
extremely conservative.

2024), 89 FR 84960 (October 24, 2024) (SR-NYSEAMER-2024-49) (order

``Arca GBTC Options Notice'').
    \32\ See Arca Rule 6.8-O Commentary .06(e) (providing at 
subparagraph (e) that the position limit shall be 250,000 contracts

that had trading volume of at least 100,000,000 shares during the 
most recent six-month trading period; or (ii) on an underlying stock 
or Exchange-Traded Fund Share that had trading volume of at least 
75,000,000 shares during the most recent six-month trading period 
and has at least 300,000,000 shares currently outstanding).
    \33\ The market capitalization of GBTC was determined by 
multiplying a settlement price ($75.42) by the number of shares 
outstanding (273,950,100). Data represents figures from FactSet as 
of November 25, 2024.
    \34\ See https://www.coingecko.com/en/coins/bitcoin.
    \35\ This is the approximate price of bitcoin from 4:00 p.m. ET 
on November 25, 2024.
    \36\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/273,950.100 shares 
outstanding).
---------------------------------------------------------------------------

    First, Arca reviewed GBTC's data relative to the market 
capitalization of the entire bitcoin market in terms of exercise risk 
and availability of deliverables. As noted above, as of November 25, 
2024, there were 19,787,762 bitcoins in circulation.\37\ At a price of 
$94,830 per bitcoin,\38\ Arca noted that equates to a market 
capitalization of greater than $1.876 trillion. If an aggregated 
position (and exercise) limit of 250,000 contracts were considered, the 
exercisable risk would represent 9.13% \39\ of the outstanding shares 
outstanding of GBTC. Since GBTC has a creation and redemption process 
managed through the issuer (whereby bitcoin is used to create GBTC 
shares), the position limit can be compared to the total market 
capitalization of the entire bitcoin market, and in that case, the 
exercisable risk for options on GBTC would represent less than 0.10% of 
all bitcoin outstanding.\40\ The Exchange notes that if GBTC options 
were subject to a 250,000-contract position and exercise limit (based 
on GBTC trading volume) and if all options on GBTC shares were 
exercised at once, this occurrence would have a virtually unnoticed 
impact on the entire bitcoin market. This analysis demonstrates that a 
250,000-contract position (and exercise) limit for GBTC options would 
be appropriate given GBTC's liquidity.
---------------------------------------------------------------------------

    \37\ See https://www.coingecko.com/en/coins/bitcoin.
    \38\ This is the approximate price of bitcoin from 4:00 p.m. ET 
on November 25, 2024.
    \39\ This percentage is arrived at with this equation: (250,000 
contract limit * 100 shares per option/273,950,100 shares 
outstanding).
    \40\ This number was arrived at with this calculation: ((250,000 
limit * 100 shares per option * $75.42 settle)/(19,787,762 BTC 
outstanding * $94,830 BTC price)).
---------------------------------------------------------------------------

    Next, Arca reviewed the proposed position limit by comparing it to 
position limits for derivative products regulated by the CFTC. While 
the CFTC, through the relevant Designated Contract Markets, only 
regulates options positions based upon delta equivalents (creating a 
less stringent standard), Arca examined equivalent bitcoin futures 
position limits. In particular, Arca looked to the CME bitcoin futures 
contract,\41\ which has a position limit of 2,000 futures (for the 
initial spot month).\42\ Arca noted that, on October 22, 2024, CME 
bitcoin futures settled at $94,945.\43\ Arca noted that on October 22, 
2024, GBTC settled at $53.64, which would equate to greater than 
17,700,410 shares of GBTC if the CME notional position limit was 
utilized. Since substantial portions of any distributed options 
portfolio are likely to be out of the money on expiration, an options 
position limit equivalent to the CME position limit for bitcoin futures 
(considering that all options deltas are <=1.00) should be a bit higher 
than the CME implied limit of 177,004.
---------------------------------------------------------------------------

    \41\ CME Bitcoin Futures are described in Chapter 350 of CME's 
Rulebook.
    \42\ See the Position Accountability and Reportable Level Table 
in the Interpretations & Special Notices Section of Chapter 5 of 
CME's Rulebook. Each CME bitcoin futures contract is valued at five 
bitcoins as defined by the CME CF Bitcoin Reference Rate (``BRR''). 
See CME Rule 35001.
    \43\ 2,000 futures at a 5-bitcoin multiplier (per the contract 
specifications) equates to $949,450,000 (2000 contracts * 5 BTC per 
contract * $94,945 price of November BTC future) of notional value.
---------------------------------------------------------------------------

    Of note, unlike options contracts, CME position limits are 
calculated on a net futures-equivalent basis by contract and include 
contracts that aggregate into one or more base contracts according to 
an aggregation ratio(s).\44\ Therefore, if a portfolio includes 
positions in options on futures, CME would aggregate those positions 
into the underlying futures contracts in accordance with a table

position within one business day without being considered in violation 
of its rules. Additionally, if at the close of trading, a position that 
includes options exceeds position limits for futures contracts, when 
evaluated using the delta factors as of that day's close of trading but 
does not exceed the limits when evaluated using the previous day's 
delta factors, then the position shall not constitute a position limit

violation. Considering CME's position limits on bitcoin futures, the 
Exchange believes a 250,000-contract limit for GBTC options would be 
appropriate.

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

    Finally, Arca analyzed a position and exercise limit of 250,000 for 
GBTC against options on SPDR Gold Shares (``GLD''), which (like GBTC), 
is a commodity-backed ETF.\46\ Arca noted that GLD has a float of 306.1 
million shares and a position limit of 250,000 contracts.\47\ As 
previously noted, position and exercise limits are designed to limit 
the number of options contracts traded on the exchange in an underlying 
security that an investor, acting alone or in concert with others 
directly or indirectly, may control. Arca noted that a position limit 
exercise in GLD would represent 8.17% of the float of GLD. In 
comparison, Arca noted that a 250,000 contract position limit in GBTC 
would represent 9.13% of the float of GBTC. While less conservative 
than the standard applied to options on GLD, Arca nonetheless believes 
that subjecting GBTC options to a 250,000 contract position and 
exercise limit would be appropriate.\48\
---------------------------------------------------------------------------

    \46\ GLD, like GBTC, holds one asset in trust.
    \47\ See https://www.ssga.com/us/en/intermediary/etfs/spdr-gold-shares-gld.
    \48\ See, e.g., Arca Rule 6.8-O, Commentary .06(e) (setting 
forth trading volume requirements to qualify for a 250,000-contract 
position (and exercise) limit).
---------------------------------------------------------------------------

    Based on the foregoing, the Exchange believes that GBTC has more 
than sufficient liquidity to garner an increased position and exercise 
limit of 250,000 same-side contracts. The Exchange believes that the 
significant liquidity present in GBTC mitigates against the potential 
for manipulation.
    The Exchange also has no reason to believe that the growth in 
trading volume in BTC, BITB, and GBTC options will not continue. 
Rather, the Exchange expects continued options volume growth in BTC, 
BITB, and GBTC as opportunities for investors to participate in the 
options markets increase and evolve. The Exchange believes that the 
current position and exercise limits in BTC, BITB, and GBTC options are 
restrictive and will hamper the listed options markets from being able 
to compete fairly and effectively with the over-the-counter (``OTC'') 
markets. OTC transactions occur through bilateral agreements, the terms 
of which are not publicly disclosed to the marketplace. As such, OTC 
transactions do not contribute to the price discovery process on a 
public exchange or other lit markets. The Exchange believes that 
without the proposed changes to position and exercise limits for BTC, 
BITB, and GBTC options, market participants will find the 25,000-
contract position limit an impediment to their business and investment 
objectives as well as an impediment to efficient pricing. As a result, 
market participants may find the less transparent OTC markets a more 
attractive alternative to achieve their investment and hedging 
objectives, leading to a retreat from the listed options markets, where 
trades are subject to reporting requirements and daily surveillance.
    The Exchange believes that the existing surveillance procedures and 
reporting requirements at the Exchange are capable of properly 
identifying disruptive and/or manipulative trading activity. The 
Exchange also represents that it has adequate surveillances in place to 
detect potential manipulation, as well as reviews in place to identify 
continued compliance with the Exchange's listing standards. These 
procedures monitor market activity to identify unusual activity in both 
options and the underlying equities.
FLEX
    Arca recently received approval to permit BTC, BITB and GTBC to 
trade as ``FLEX Options.'' \49\ Identical to approval received by Arca, 
ISE proposes to permit BTC, BITB and GTBC to trade as FLEX Options and 
would require the aggregation of any FLEX and non-FLEX positions in the 
same underlying ETF for purposes of calculating position and exercise 
limits on such ETF. Thus, for example, assuming a 250,000-contract 
position limit for options on BTC, the Exchange would restrict a market 
participant from holding positions that could result in the receipt of 
more than 250,000,000 shares (if that market participant exercised all 
its BTC options). The share creation and redemption process available 
to each ETF is designed to ensure that an ETF's price closely tracks 
the value of its underlying asset. For example, if a market participant 
exercised a long call position for 25,000 contracts and purchased 
2,500,000 shares of BTC and this purchase resulted in the value of BTC 
shares to trade at a premium to the value of the (underlying) bitcoin 
held by BTC, the Exchange believes that other market participants would 
attempt to arbitrage this price difference by selling short BTC shares 
while concurrently purchasing bitcoin. Those market participants 
(arbitrageurs) would then deliver cash to BTC and receive shares of 
BTC, which would be used to close out any previously established short 
position in BTC. Thus, this creation and redemptions process would 
significantly reduce the potential risk of price dislocation between 
the value of BTC shares and the value of bitcoin holdings.

    \49\ See Securities Exchange Act Release Nos. 103568 (July 29, 
2025) (SR-NYSEArca-2025-10) (not yet noticed); and 103567 (July 29, 
2025) (SR-NYSEArca-2025-07) (not yet noticed).
---------------------------------------------------------------------------

    The Exchange understands that FLEX Options on ETFs are currently 
traded in the OTC market by a variety of market participants, e.g., 
hedge funds, proprietary trading firms, and pension funds, to name a 
few. The Exchange believes there is room for significant growth if a 
comparable product were introduced for trading on a regulated market. 
The Exchange expects that users of these OTC products would be among 
the primary users of FLEX options on BTC, BITB and GTBC. The Exchange 
also believes that the trading of FLEX Options would allow these same 
market participants to better manage the risk associated with the 
volatility of BTC, BITB or GTBC (the underlying ETF) positions given 
the enhanced liquidity that an exchange-traded product would bring. 
Additionally, the Exchange believes that FLEX Options traded on the 
Exchange would have three important advantages over the contracts that 
are traded in the OTC market. First, because of greater standardization 
of contract terms, exchange-traded contracts should develop more 
liquidity. Second, counter-party credit risk would be mitigated by the 
fact that the contracts are issued and guaranteed by OCC. Finally, the 
price discovery and dissemination provided by the Exchange and its 
members would lead to more transparent markets. The Exchange believes 
that its ability to offer FLEX Options would aid it in competing with 
the OTC market and at the same time expand the universe of products 
available to interested market participants. The Exchange believes that 
an exchange-traded alternative may provide a useful risk management and 
trading vehicle for market participants and their customers.
    The Exchange has analyzed its capacity and represents that it and 
OPRA have the necessary systems capacity to handle the additional 
traffic associated with the listing of FLEX Options. The Exchange 
believes any additional traffic that would be generated from the 
trading of FLEX Options would be manageable. The Exchange believes OTP 
Holders will not have a capacity issue as a result of this proposed 
rule change. The Exchange also represents that it does not believe this 
proposed rule change will cause fragmentation of liquidity. The 
Exchange will monitor the trading

[[Page 38533]]

volume associated with the additional options series listed as a result 
of this proposed rule change and the effect (if any) of these 
additional series on market fragmentation and on the capacity of the 
Exchange's automated systems.
    The Exchange represents that the same surveillance procedures 
applicable to the Exchange's other options products listed and traded 
on the Exchange, including non-FLEX Options, will apply to FLEX 
Options, and that it has the necessary systems capacity to support such 
options. FLEX Options products (and their respective symbols) are 
integrated into the Exchange's existing surveillance system 
architecture and are thus subject to the relevant surveillance 
processes. The Exchange's market surveillance staff (including staff of 
Financial Industry Regulatory Authority, Inc. (``FINRA'') who perform 
surveillance and investigative work on behalf of the Exchange pursuant 
to a regulatory services agreement) conducts surveillances with respect 
to BTC, BITB and GTBC (the underlying ETFs) and, as appropriate, would 
review activity in BTC, BITB and GTBC when conducting surveillances for 
market abuse or manipulation in the FLEX options on each ETF. The 
Exchange does not believe that allowing FLEX Options would render the 
marketplace for non-FLEX Options, or equity options in general, more 
susceptible to manipulative practices.
    The Exchange represents that its existing trading surveillances are 
adequate to monitor the trading in BTC, BITB and GTBC as well as any 
subsequent trading of FLEX Options on the Exchange. Additionally, the 
Exchange is a member of the Intermarket Surveillance Group (``ISG'') 
under the ISG Agreement. ISG members work together to coordinate 
surveillance and investigative information sharing in the stock, 
options, and futures markets. In addition to the surveillance that is 
conducted by the Exchange's market surveillance staff, the Exchange 
would also be able to obtain information regarding trading in shares of 
BTC, BITB and GTBC on other exchanges through ISG. In addition, and as 
referenced above, the Exchange has a regulatory services agreement with 
FINRA, pursuant to which FINRA conducts certain surveillances on behalf 
of the Exchange. Further, pursuant to a multi-party 17d-2 joint plan, 
all options exchanges allocate regulatory responsibilities to FINRA to 
conduct certain options-related market surveillances.\50\ The Exchange 
will implement any additional surveillance procedures it deems 
necessary to effectively monitor the trading of BTC, BITB and GTBC 
options.
---------------------------------------------------------------------------

    \50\ Section 19(g)(1) of the Act, among other things, requires 
every SRO registered as a national securities exchange or national 
securities association to comply with the Act, the rules and 
regulations thereunder, and the SRO's own rules, and, absent 
reasonable justification or excuse, enforce compliance by its 
members and persons associated with its members. See 15 U.S.C. 
78q(d)(1) and 17 CFR 240.17d-2. Section 17(d)(1) of the Act allows 
the Commission to relieve an SRO of certain responsibilities with 
respect to members of the SRO who are also members of another SRO. 
Specifically, Section 17(d)(1) allows the Commission to relieve an 
SRO of its responsibilities to: (i) receive regulatory reports from 
such members; (ii) examine such members for compliance with the Act 
and the rules and regulations thereunder, and the rules of the SRO; 
or (iii) carry out other specified regulatory responsibilities with 
respect to such members.
---------------------------------------------------------------------------

    The proposed rule change is designed to allow investors seeking to 
trade options on BTC, BITB and GTBC to utilize FLEX Options. The 
Exchange believes that offering innovative products flows to the 
benefit of the investing public. A robust and competitive market 
requires that exchanges respond to member's evolving needs by 
constantly improving their offerings. Such efforts would be stymied if 
exchanges were prohibited from offering innovative products such as the 
proposed FLEX Options. The Exchange believes that introducing FLEX 
Options would further broaden the base of investors that use FLEX 
Options (and options on BTC, BITB and GTBC, in general) to manage their 
trading and investment risk, including investors that currently trade 
in the OTC market for customized options. The proposed rule change is 
also designed to encourage Market Makers to shift liquidity from the 
OTC market on the Exchange, which, it believes, will enhance the 
process of price discovery conducted on the Exchange through increased 
order flow.
2. Statutory Basis
    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act,\51\ in general, and furthers the objectives of Section 
6(b)(5) of the Act,\52\ 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.

Position Limits
BTC and BITB
    The Exchange believes the proposed rule change to remove the 
25,000-contract position (and exercise) limit on BTC and BITB options 
thus allowing such options to qualify for higher aggregated limits will 
remove impediments to and perfect the mechanism of a free and open 
market and a national market system, and, in general, protect investors 
and the public interest as it will provide market participants with the 
ability to more effectively execute their trading and hedging 
activities. In addition, this proposed change may allow Market Makers 
to maintain their liquidity in these options in amounts commensurate 
with the continued demand for BTC and BITB options. Further, an 
increased aggregated position (and exercise) limit on BTC and BITB 
options may encourage other liquidity providers to continue to trade on 
the Exchange rather than shift their volume to OTC markets, which will 
enhance the process of price discovery conducted on the Exchange 
through increased order flow. The Exchange notes that permitting a 
higher aggregated position (and exercise) limit on BTC and BITB options 
would further allow institutional investors to utilize such options for 
prudent risk management purposes.
    As noted herein, Arca analyzed several data points that support the 
appropriateness of an aggregated position (and exercise) limit of 
250,000 contracts for BTC and BITB options based on recent trading 
volume in each ETF. Specifically, Arca noted that a comparison of each 
ETF's market capitalization to the bitcoin market in terms of exercise 
risk and availability of deliverables revealed that the exercisable 
risk of an aggregated limit of 250,000 contracts represented 30.14% and 
31.27% of BTC and BITB shares outstanding. Further, since each ETF has 
a creation and redemption process managed through the issuer (whereby 
bitcoin is used to create BTC or BITB shares, as applicable), a 
250,000-contract position (and exercise) limit as compared to the 
market capitalization of the bitcoin market indicated that the 
exercisable risk for options on each ETF represented less than 0.06% 
(BTC) or 0.07% (BITB) of all bitcoin outstanding as noted by Arca. 
Moreover, a comparison of a 250,000-contract position limit for options 
on each ETF to the (actual) position limits for

[[Page 38534]]

equivalent bitcoin futures revealed that a 250,000-contract limit for 
each ETF would be appropriate. Finally, Arca compared an aggregated 
position limit of 250,000 contracts for each ETF against GLD, another 
commodity-backed ETF. A position limit exercise in GLD represents 8.17% 
of the float of GLD. By comparison, Arca noted that a position limit 
exercise in each ETF (assuming a 250,000-contract limit would represent 
30.14% (BTC) and 31.27% (BITB) of that ETF's float. Although a 250,000-
contract position (and exercise) limit on BTC and BITB options would 
not be as conservative as the standard applied to GLD, it is comparable 
and therefore appropriate.
GBTC
    The Exchange believes the proposed rule change to remove the 
25,000-contract position (and exercise) limit on GBTC options thus 
allowing such options to qualify for higher aggregated limits will 
remove impediments to and perfect the mechanism of a free and open 
market and a national market system, and, in general, protect investors 
and the public interest as it will provide market participants with the 
ability to more effectively execute their trading and hedging 
activities. In addition, this proposed change may allow Market Makers 
to maintain their liquidity in these options in amounts commensurate 
with the continued demand for GBTC options. Further, an increased 
aggregated position (and exercise) limit on GBTC options may encourage 
other liquidity providers to continue to trade on the Exchange rather 
than shift their volume to OTC markets, which will enhance the process 
of price discovery conducted on the Exchange through increased order 
flow. The Exchange notes that permitting a higher aggregated position 
(and exercise) limit on GBTC options would further allow institutional 
investors to utilize such options for prudent risk management purposes.
    As noted herein, Arca analyzed several data points that support the 
appropriateness of an aggregated position (and exercise) limit of 
250,000 contracts for GBTC options based on recent trading volume in 
GBTC. Specifically, Arca noted that a comparison of GBTC's market 
capitalization to the bitcoin market in terms of exercise risk and 
availability of deliverables revealed that the exercisable risk of an 
aggregated limit of 250,000 contracts represented 9.13% of GBTC shares 
outstanding. Further, since GBTC has a creation and redemption process 
managed through the issuer (whereby bitcoin is used to create GBTC 
shares), a 250,000-contract position (and exercise) limit as compared 
to the market capitalization of the bitcoin market indicated that the 
exercisable risk for GBTC options represented less than 0.10% of all 
bitcoin outstanding as noted by Arca. Moreover, a comparison of a 
250,000-contract position limit for GBTC options to the (actual) 
position limits for equivalent bitcoin futures revealed that a 250,000-
contract limit would be appropriate. Finally, Arca compared an 
aggregated position limit of 250,000 contracts for GBTC options against 
GLD, another commodity backed ETF. Arca noted that a position limit 
exercise in GLD represents 8.17% of the float of GLD. By comparison, a 
position limit exercise in GBTC options (assuming a 250,000-contract 
limit) would represent 9.13% of the GBTC float. Although a 250,000-
contract position (and exercise) limit on GBTC options would not be as 
conservative as the standard applied to GLD, it is comparable and 
therefore appropriate.
FLEX
    The Exchange believes that the proposal to permit FLEX Options and 
to require aggregation of any FLEX and non-FLEX positions in the same 
underlying ETF for BTC, BITB and GTBC for purposes of calculating 
position and exercise limits would remove impediments to and perfect 
the mechanism of a free and open market for several reasons. First, the 
Exchange believes that offering FLEX Options will benefit investors by 
providing them with an additional, relatively lower cost investing tool 
to gain exposure to the price of bitcoin and provide a hedging vehicle 
to meet their investment needs in connection with a bitcoin-related 
product. Moreover, the proposal would broaden the base of investors 
that use FLEX Options to manage their trading and investment risk, 
including investors that currently trade in the OTC market for 
customized options. By trading a product in an exchange-traded 
environment (that is currently being used in the OTC market), the 
Exchange would be able to compete more effectively with the OTC market. 
The Exchange believes the proposed rule change is designed to prevent 
fraudulent and manipulative acts and practices in that it would lead to 
the migration of options currently trading in the OTC market to trading 
to the Exchange. Also, any migration to the Exchange from the OTC 
market would result in increased market transparency and enhance the 
process of price discovery conducted on the Exchange through increased 
order flow. The Exchange also believes that offering FLEX Options may 
open up the market for options on BTC, BITB and GTBC to more retail 
investors.
    Additionally, the Exchange believes the proposed rule change is 
designed to remove impediments to and to perfect the mechanism for a 
free and open market and a national market system, and, in general, to 
protect investors and the public interest because FLEX Options are 
designed to create greater trading and hedging opportunities and 
flexibility. The proposed rule change should also result in enhanced 
efficiency in initiating and closing out positions and heightened 
contra-party creditworthiness due to the role of OCC as issuer and 
guarantor of FLEX Options. Further, the proposed rule change would 
result in increased competition by permitting the Exchange to offer 
products that are currently used in the OTC market.
    The Exchange believes that offering innovative products flows to 
the benefit of the investing public. A robust and competitive market 
requires that exchanges respond to members' evolving needs by 
constantly improving their offerings. Such efforts would be stymied if 
exchanges were prohibited from offering innovative products such as the 
proposed FLEX Options. The Exchange does not believe that allowing FLEX 
Options would render the marketplace for equity options more 
susceptible to manipulative practices.
    Finally, the Exchange represents that it has an adequate 
surveillance program in place to detect manipulative trading in FLEX 
Options. Regarding the proposed FLEX Options, the Exchange would use 
the same surveillance procedures currently utilized for FLEX Options 
listed on the Exchange (as well as for non-FLEX Options). For 
surveillance purposes, the Exchange would have access to information 
regarding trading activity in BTC, BITB and GTBC the underlying ETFs). 
In light of surveillance measures related to both options trading on 
BTC, BITB and GTBC and the underlying funds, the Exchange believes that 
existing surveillance procedures are designed to deter and detect 
possible manipulative behavior which might potentially arise from 
listing and trading the proposed FLEX Options.

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.

[[Page 38535]]

Position Limits
    The Exchange's proposal does not burden intra-market competition 
because all ISE Members would be subject to the position limits in 
Options 9, Sections 13(d) and corresponding exercise limits in Options 
9, Section 15. The Exchange believes that the proposed rule change will 
also provide additional opportunities for market participants to 
continue to efficiently achieve their investment and trading objectives 
for equity options on the Exchange.
    The Exchange does not believe that the proposed rule change will 
impose any burden on inter-market competition. The Exchange expects 
that all option exchanges will adopt substantively similar proposals, 
such that the Exchange's proposal would benefit competition. For these 
reasons, the Exchange does not believe that the proposed rule change 
will impose any burden on competition not necessary or appropriate in 
furtherance of the purposes of the Act.
FLEX
    The Exchange believes that the proposal to permit FLEX Options will 
not impose any burden on intra-market competition as all market 
participants can opt to utilize this product or not. The proposed rule 
change is designed to allow investors seeking option exposure to 
bitcoin to trade FLEX Options. Moreover, the Exchange believes that the 
proposal to permit FLEX Options would broaden the base of investors 
that use FLEX Options to manage their trading and investment risk, 
including investors that currently trade in the OTC market for 
customized options. The Exchange believes that the proposed FLEX 
Options will not impose any burden on inter-market competition but will 
instead encourage competition by increasing the variety of options 
products available for trading on the Exchange, which products will 
provide a valuable tool for investors to manage risk. Should this 
proposal be approved, competing options exchanges will be free to offer 
products like the proposed FLEX Options.

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

    No written comments were either solicited or 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)(iii) of the Act \53\ and Rule 19b-4(f)(6) thereunder.\54\ 
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 \55\ and subparagraph (f)(6) of 
Rule 19b-4 thereunder.\56\

    \53\ 15 U.S.C. 78s(b)(3)(A)(iii).

    \55\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \56\ 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 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 the pre-filing requirement.
---------------------------------------------------------------------------

    A proposed rule change filed under Rule 19b-4(f)(6) \57\ under the 
Act does not normally become operative prior to 30 days after the date 
of the filing. However, pursuant to Rule 19b-4(f)(6)(iii),\58\ the 
Commission may designate a shorter time if such action is consistent 
with the protection of investors and the public interest. The Exchange 
has requested that the Commission waive the 30-day operative delay so 
that the proposal may become operative immediately upon filing. The 
Commission previously approved the removal of the 25,000 contract 
position and exercise limit for BTC, GBTC, and BITB, such that those 
funds will be subject to the position and exercise limits as determined 
for equity options for which no set limit has been otherwise 
established on that exchange.\59\ The Exchange is proposing similarly 
to remove of the 25,000 contract position and exercise limit for BTC, 
GBTC, and BITB, such that those funds will be subject to the position 
and exercise limits as determined by the position limit rules at ISE 
Options 9, Section 13 and exercise limit rules at ISE Options 9, 
Section 15. In addition, the Exchange proposes to permit BTC, GTBC, and 
BITB to trade as FLEX Options and would require the aggregation of any 
FLEX and non-FLEX positions in the same underlying ETF for purposes of 
calculating position and exercise limits on such ETF, substantively 
identical to approval received by another exchange.\60\ The Exchange 
has provided information regarding BTC, GBTC, and BITB, including, 
among other things, information regarding trading volume, and the 
market capitalization of BTC, GBTC, and BITB and surveillance 
procedures that will apply. The Commission notes that the proposal 
raises no new or novel legal issues and would simply provide an 
additional venue for trading BTC, GBTC, and BITB with position and 
exercise limits that may be higher than 25,000 contracts, as well as 
FLEX trading on BTC, GBTC, and BITB. Therefore, the Commission believes 
that waiver of the 30-day operative delay is consistent with the 
protection of investors and the public interest. Accordingly, the 
Commission hereby waives the 30-day operative delay and designates the 
proposed rule change as operative upon filing.\61\

the Commission has also 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.
