# Self-Regulatory Organizations; MIAX Sapphire, LLC; Notice of Filing of a Proposed Rule Change To Amend Exchange Rule 527
Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Exchange Act” or “Act”), [^1] and Rule 19b-4 thereunder, [^2] notice is hereby given that on August 15, 2025, MIAX Sapphire, LLC (“MIAX Sapphire” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”) a 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 Exchange Rule 527, Exchange Liability, to provide a one-time accommodation payment to Members [^3] for claims arising from the system difficulties that the Exchange experienced on June 3, 2025 as a result of an operational error (referred to herein as the “Operational Error”). Upon approval of this proposal by the U.S. Securities and Exchange Commission (the “Commission”), the Exchange will implement the accommodation payment process described in proposed subparagraph (e) to Exchange Rule 527 and expects to fully compensate all Members that incurred a loss validated by the Exchange as a result of the Operational Error (described in more detail below).
[^3] The term “Member” means an individual or organization that is registered with the Exchange pursuant to Chapter II of the Exchange's Rules for purposes of trading on the Exchange as an “Electronic Exchange Member” or “Market Maker.” Members are deemed “members” under the Exchange Act. *See* Exchange Rule 100.
The text of the proposed rule change is available on the Exchange's website at *https://www.miaxglobal.com/markets/us-options/miax-sapphire/rule-filings* and at the Exchange's principal office.
**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**
On June 3, 2025, the Exchange experienced system difficulties as a result of the Operational Error, which caused the Exchange's simulation/testing environment to connect to the MIAX Sapphire production ports and inject data into the MIAX Sapphire matching engines in the live trading environment. Upon discovery of this issue, trading in all symbols on the Exchange was halted at 11:49 a.m. [^4] and the Exchange published a Trading Alert at 11:53 a.m. to announce the trading halt. In the interest of ensuring fair and orderly markets and for the protection of investors, the Exchange determined that it would cancel all trades that occurred between approximately 11:18 a.m. and 11:33 a.m. [^5] Members were notified at 1:07 p.m. that all trades during that time period would be canceled. By 1:54 p.m., the Exchange provided all impacted Members with specific trade details relating to their canceled trades. The Exchange fully remediated the issue and all trading systems began operating normally that same day. The Exchange issued several alerts throughout this period, including alerts to announce the halt, that the Exchange would cancel all trades, the time when the Exchange would resume trading, the time for Members to submit claims for losses, and a post mortem of the Operational Error. [^6]
[^4] All times referenced in this filing are in Eastern Standard Time.
[^5] The Exchange canceled these trades under the authority provided by Exchange Rule 523, Authority to Take Action Under Emergency Conditions. *See* Exchange Rule 523(a) (providing that the “Chairman of the Board . . . shall have the power to halt or suspend trading . . . for the maintenance of a fair and orderly market or the protection of investors . . . due to emergency conditions . . . such as (1) . . . loss or interruption of facilities utilized by the Exchange . . .”).
[^6]*See* Regulatory, Technical and Trading Alerts issued by the Exchange on June 3, 2025 and June 4, 2025, *available at**https://miaxglobal.com/alert/2025/06/03/miax-sapphire-options-exchange-halted-all-symbols-114929-am; https://www.miaxglobal.com/alert/2025/06/03/miax-sapphire-options-exchange-busting-all-trades-between-111828506201536;**https://www.miaxglobal.com/alert/2025/06/03/miax-sapphire-options-exchange-will-resume-trading-230-pm; https://www.miaxglobal.com/alert/2025/06/03/miax-sapphire-options-exchange-all-trades-busted-between-111828506201536;**https://www.miaxglobal.com/alert/2025/06/03/miax-sapphire-options-claims-related-issue-today-sapphire-options; and**https://www.miaxglobal.com/alert/2025/06/04/miax-sapphire-options-exchange-post-mortem.*
Since the June 3, 2025 Operational Error, Members compiled their trade data showing losses as a result of the Operational Error and the Exchange canceling all trades during the specific timeframe described above. The Exchange reviewed the events of June 3, 2025 with the goal of proposing a fair and equitable accommodation policy that is consistent with the Exchange Act and MIAX Sapphire's self-regulatory obligations. The Exchange believes this proposal reflects MIAX Sapphire's effort to: (i) identify the categories of investors and Members that the Operational Error caused objective, discernible harm, and the type and scope of such harm; and (ii) propose an objectively reasonable and balanced regulatory plan for accommodating Members and their investor customers for such harm by providing a payment in excess of the Exchange's current rules regarding limitation of liability. MIAX Sapphire has undertaken this effort notwithstanding the liability protections afforded by its contractual limitations of liability and Exchange Rule 527—the rule that MIAX Sapphire proposes to modify.
The Exchange's current limitation of liability rules, described in detail below, limit the maximum amount of compensation Members are able to receive from the Exchange arising out of a system issue that impacts the use or enjoyment of the facilities or services afforded by the Exchange, such as the Operational Error. In the interest of protecting Members and their investor customers, [^7] the Exchange proposes to amend Exchange Rule 527 to provide a one-time voluntary accommodation for claims arising from the June 3, 2025 Operational Error.
[^7] The majority of claims are from customers of Member firms who utilize a Member firm as their introducing broker to access and submit orders to the Exchange for execution.
This type of accommodation plan is not without precedent. In 2012, the Nasdaq Stock Market LLC (“Nasdaq”) experienced system difficulties in the Nasdaq halt and imbalance cross process in connection with the initial public offering (“IPO”) of Facebook, Inc. (“Facebook”). In response, Nasdaq filed with the Commission a proposal to establish an accommodation policy providing compensation for impacted investors in excess of Nasdaq's then-applicable limitation of liability rules, which proposal was approved by the Commission. [^8]
[^8]*See* Securities Exchange Act Release No. 69216 (March 22, 2013), 78 FR 19040 (March 28, 2013) (SR-NASDAQ-2012-090); *see also* Nasdaq Rules, Equity 2, Section 17. The Exchange's proposal differs from the Nasdaq accommodation filing in several minor respects but ultimately provides a substantively similar accommodation for Members impacted by the Operational Error to be compensated in excess of the Exchange's current limitation of liability limits. Nasdaq also undertook a two-step process to compensate its members and customers by first proposing the accommodation policy and then filing a separate rule proposal with the Commission to implement the accommodation policy. *See* Securities Exchange Act Release No. 71098 (December 17, 2023), 78 FR 77540 (December 23, 2013) (SR-NASDAQ-2013-152). The Exchange proposes a single-step process since the Exchange has already received and validated all claims from Members that were impacted by the Operational Error; brought the proposed accommodation plan and total value of eligible claims to its Board of Directors for approval; and is ready to promptly compensate Members for their validated claims upon approval of this proposal by the Commission.
**Current Limitation of Liability Provisions**
Exchange Rule 527(a) describes the general limitations on liability of the Exchange, its directors, officers, committee members, limited liability company members, employees or agents. Exchange Rule 527(a) provides, in relevant part, that except as provided in paragraph (b) of Exchange Rule 527 or otherwise expressly provided in the Exchange's rules, neither the Exchange nor its directors, officers, committee members, limited liability company members, employees or agents shall be liable to Members or persons associated therewith for any loss, expense, damages, or other claims arising out of the use or enjoyment of the facilities or services afforded by the Exchange, including the interruption in or failure or unavailability of such facilities or services, or any action taken or omitted in respect to the business of the Exchange. Exchange Rule 527(a) provides limited exceptions to these limitations in connection with Exchange employee acts where the extent of such loss, expense, damages or claims are attributable to the willful misconduct, gross negligence, bad faith or fraudulent or criminal acts of the Exchange or its officers, employees or agents acting within the scope of their authority.
Exchange Rule 527(b) further describes exceptions to the Exchange's general limitation of liability rule that allows for the payment of compensation to Members for Exchange System [^9] issues, subject to certain conditions, which limit the maximum amount of Exchange liability. The exceptions under Exchange Rule 527(b) apply whenever custody of an unexecuted order [^10] or quote [^11] is transmitted by a Member to or through the Exchange's System or to any other automated facility of the Exchange whereby the Exchange assumes responsibility for the transmission or execution of the order or quote, provided that the Exchange has acknowledged receipt of such order or quote.
[^9] The term “System” means the automated trading system used by the Exchange for the trading of securities. *See* Exchange Rule 100.
[^10] The term “order” means a firm commitment to buy or sell option contracts. *See* Exchange Rule 100.
[^11] The term “quote” or “quotation” means a bid or offer entered by a Market Maker as a firm order that updates the Market Maker's previous bid or offer, if any. When the term order is used in these Rules and a bid or offer is entered by the Market Maker in the option series to which such Market Maker is registered, such order shall, as applicable, constitute a quote or quotation for purposes of these Rules. *See* Exchange Rule 100.
Subparagraphs (b)(1) through (b)(3) of Exchange Rule 527 set forth the limits for claims made by Members, individually and in the aggregate, related to Exchange System issues that impact the use or enjoyment of the facilities of the Exchange. The liability limits provided for in Exchange Rules 527(b)(1)-(3) are as follows: (1) as to any one or more claims made by a single Member growing out of the use or enjoyment of the facilities afforded by the Exchange on a single trading day, the Exchange shall not be liable in excess of the larger of $100,000 or the amount of any recovery obtained by the Exchange under any applicable insurance maintained by the Exchange; (2) as to the aggregate of all claims made by all Members growing out of the use or enjoyment of the facilities afforded by the Exchange on a single trading day, the Exchange shall not be liable in excess of the larger of $250,000 or the amount of the recovery obtained by the Exchange under any applicable insurance maintained by the Exchange; and (3) as to the aggregate of all claims made by all Members growing out of the use or enjoyment of the facilities afforded by the Exchange during a single calendar month, the Exchange shall not be liable in excess of the larger of $500,000 or the amount of the recovery obtained by the Exchange under any applicable insurance maintained by the Exchange.
Exchange Rule 527(c) provides that if all of the claims arising out of the use or enjoyment of the facilities afforded by the Exchange cannot be fully satisfied because, in the aggregate, they exceed the applicable maximum amount of liability provided for in subparagraph (b) of Exchange Rule 527, then such maximum amount shall be allocated among all such claims arising on a single trading day or during a single calendar month, as applicable, based upon the proportion that each claim bears to the sum of all claims. Subparagraph (c) further provides that in order for claims to be included in this allocation, Members must submit written notice of their claim to the Exchange no later than the opening of trading on the next business day following the day on which the use or enjoyment of Exchange facilities giving rise to the claim occurred.
**Background of the Operational Error and Calculation of Losses**
As described above, due to the Operational Error on June 3, 2025, the Exchange determined to cancel all trades executed on MIAX Sapphire between 11:18 a.m. and 11:33 a.m. Upon learning of the Operational Error, members of the Exchange's Regulatory Operations Department contacted all Members to discuss the Operational Error, the Exchange's proposed method of remedying trades based on erroneous simulation/testing environment data, and the manner in which Members should submit claims for compensation. Members were advised to immediately contact their customers and to compile execution reports for trades made during the timeframe of the Operational Error as well as execution reports for “replacement trades” [^12] made following the timeframe of the Operational Error to fulfill the original terms of the trades that the Exchange canceled. In some instances, Members executed new valid trades at away-exchanges. Some Members executed the new valid trade several days following the Operational Error as some of their customers did not learn of the cancelations until they logged back into their brokerage accounts. [^13] Members summed the difference between the net execution price of the canceled trade on MIAX Sapphire and the net execution price for the replacement trade made on MIAX Sapphire or at an away-exchange and then provided such information to the Exchange.
[^12] For the purposes of this filing and the proposed new rule text, unless stated otherwise, the term “replacement trade” shall be construed to mean the new trade executed by a Member on MIAX Sapphire or at an away-exchange that was executed to replace the original trade that was canceled by MIAX Sapphire during the timeframe of the Operational Error. *See* proposed Exchange Rule 527(e)(1)(iii).
[^13] For example, the Exchange was made aware that certain retail customers that send orders to an Exchange Member for execution do not routinely check their brokerage accounts and only learned of the canceled trade due to the Operational Error days after originally placing the trade.
After receipt of all Members' claims over the course of several weeks, Exchange officials reviewed each claimed loss by validating the canceled trade execution prices reported during the timeframe of the Operational Error and the execution prices of the subsequent replacement trades. For trading losses that resulted from a Member executing the replacement trade on MIAX Sapphire, the Exchange: (A) first validated that the canceled trade took place on MIAX Sapphire during the timeframe of the Operational Error based on the Member's MPID; [^14] (B) validated the claimed execution price of the canceled trade; (C) validated that the replacement trade took place on MIAX Sapphire; and (D) validated the execution price of the replacement trade. The measure of loss was calculated based on the difference between the net execution price of the canceled trade and the execution price of the replacement trade.
[^14] The term “MPID” means unique market participant identifier. *See* Exchange Rule 100.
For trading losses that resulted from a Member executing the replacement trade on an away-exchange, the Exchange: (A) first validated that the canceled trade took place on MIAX Sapphire during the timeframe of the Operational Error based on the Member's MPID; (B) validated the claimed execution price of the canceled trade; and (C) validated the execution price of the replacement trade by comparing such price against the closing or opening price of the option, depending on the time of execution, as well as the size of the replacement trade in comparison to the original trade that was canceled. The measure of loss was calculated based on the difference between the net execution price of the canceled trade and the execution price of the replacement trade.
The Exchange determined to use the closing or opening price of the series of options for replacement trades executed on away-exchanges as an initial check to determine whether the claimed replacement trade execution price was within a reasonable range for that particular series of options. As described above, the Exchange issued an alert to inform all Members that it would cancel all trades during the timeframe of the Operational Error on June 3, 2025 at 1:07 p.m. At 1:54 p.m., the Exchange notified Members of the specific trade details for their canceled trades. As a result, the Exchange believes that customers of Members may not have been aware of the Operational Error until a day or two (or longer) following the Operational Error, thereby not executing the replacement trade until that time. [^15] Exchange officials utilized closing and opening options trade prices between June 3, 2025 and June 6, 2025, [^16] depending on the date when Members executed the replacement trades, as a reasonable baseline to compare against replacement values supplied by the Members to validate the claimed losses. In particular, if the replacement trade took place a day or more after the Operational Error, Exchange officials were able to utilize the Cboe Exchange, Inc. LiveVol® analytics platform to filter options executions by price and day to determine if the claimed replacement trade execution price and size aligned with trade executions in the same option series and size at the later date and, if so, the new execution price. The Exchange's Regulatory Operations Department followed up with all Members and received all claims from Members, including the total value of such claims, all of which were validated by Exchange officials using the methodology described above. In total, the Exchange's Regulatory Operations Department reviewed and validated over 2,200 claims that occurred during the Operational Error, all of which are eligible to be compensated.
[^15]*See supra* note 14.
[^16] Based on records provided by Members with claimed losses, June 6, 2025 was the latest date that a Member executed a valid replacement trade.
**Proposal**
The Exchange now proposes to amend Exchange Rule 527 to provide a one-time accommodation payment for Members with claims arising from the Operational Error that the Exchange experienced on June 3, 2025 that exceed the limitations provided for in Exchange Rule 527(b)(1)-(3), including the amount of compensation on a per-Member basis. The modifications proposed in this rule change are not intended to and do not affect the limitations of liability set forth in the Exchange's agreements or Commission-sanctioned rules, or those limitations or immunities that bar claims for damages against MIAX Sapphire as a matter of law. Rather, as noted above, they reflect the Exchange's determination to adopt a fair and equitable accommodation policy that takes into account the impacts of the Exchange's Operational Error on Members and their investor customers.
The Exchange proposes to establish new paragraph (e), which will state that notwithstanding paragraphs (b)(1)-(3) and paragraph (c) [^17] of Rule 527 for the single trading of June 3, 2025 and the full calendar month of June 2025, for the aggregate of all claims alleged by all market participants related to the system difficulties as a result of the Operational Error on June 3, 2025, where the Exchange's simulation/testing environment connected to the production ports (the “Operational Error”), the total amount of the Exchange's liability shall not exceed $525,000. Further, eligibility of all claims for payment shall be determined in accordance with proposed Exchange Rule 527(e) and only applies to claims previously filed with and validated by the Exchange. As noted above, the Exchange received all claims related to the Operational Error and expects that, subject to Commission approval of this proposal, all Members will be fully compensated for their claims as a result of the Operational Error.
[^17] As mentioned above, subparagraph (c) of Exchange Rule 527 provides that if all of the claims arising out of the use or enjoyment of the facilities afforded by the Exchange cannot be fully satisfied because in the aggregate they exceed the applicable maximum amount of liability provided for in paragraph (b) . . . then such maximum amount shall be allocated among all such claims arising on a single trading day or during a single calendar month, as applicable, “ *written notice of which has been given to the Exchange no later than the opening of trading on the next business day following the day on which the use or enjoyment of Exchange facilities giving rise to the claim occurred,* based upon the proportion that each such claim bears to the sum of all such claims” (emphasis added). *See* Exchange Rule 527(c). Accordingly, the Exchange proposes that the notice requirement of Exchange Rule 527(c) will not apply to claims submitted under proposed paragraph (e) to Exchange Rule 527.
Proposed subparagraph (e)(1) of Exchange Rule 527 will provide that all claims for compensation under this paragraph (e) shall arise solely from realized trading losses from executions that occurred on the Exchange on June 3, 2025 between 11:18 a.m. and 11:33 a.m. Eastern Time that the Exchange subsequently canceled pursuant to Exchange Rule 523, causing Members to execute a new trade on the Exchange or at an away-exchange to replace the canceled trade. The measure of loss was determined by the Exchange pursuant to proposed subparagraphs (e)(1)(i)-(ii), described below.
Proposed subparagraph (e)(1)(i) of Exchange Rule 527 will provide that for trading losses that resulted from a Member executing the replacement trade on MIAX Sapphire, the Exchange: (A) first validated that the canceled trade took place on MIAX Sapphire during the timeframe of the Operational Error based on the Member's MPID; (B) validated the claimed execution price of the canceled trade; (C) validated that the replacement trade took place on MIAX Sapphire; and (D) validated the execution price of the replacement trade. The measure of loss was calculated based on the difference between the net execution price of the canceled trade and the replacement trade.
Proposed subparagraph (e)(1)(ii) of Exchange Rule 527 will provide that for trading losses that resulted from a Member executing the replacement trade on an away-exchange, the Exchange: (A) first validated that the canceled trade took place on MIAX Sapphire during the timeframe of the Operational Error based on the Member's MPID; (B) validated the claimed execution price of the canceled trade; and (C) validated the execution price of the replacement trade by comparing such price against the closing or opening price of the option, depending on the time of execution, as well as the size of the replacement trade in comparison to the original trade that was canceled. The measure of loss was calculated based on the difference between the net execution price of the canceled trade and the replacement trade.
Proposed subparagraph (e)(1)(iii) of Exchange Rule 527 will provide that for purposes of this proposed Exchange Rule 527(e), unless stated otherwise, the term “replacement trade” shall be construed to mean the new trade executed by a Member on MIAX Sapphire or at an away-exchange that was executed to replace the original trade that was canceled by MIAX Sapphire during the timeframe of the Operational Error.
Proposed subparagraph (e)(2) of Exchange Rule 527 will state that in no event shall the Exchange make any payments on claims pursuant to proposed paragraph (e) until the rule proposal filed with the Commission setting forth the amount of eligible claims becomes effective and final. The Exchange proposes to make all payments for approved claims in cash.
Proposed subparagraph (e)(3) will provide that payments to Members under proposed paragraph (e) are contingent upon the submission to the Exchange of an attestation within 14 calendar days after the effective date of the rule proposal described in proposed paragraph (e)(2), detailing the information described in proposed subparagraphs (e)(1)(i)-(ii). Proposed subparagraph (e)(3) of Exchange Rule 527 will also state that failure to provide the required attestation will void the Member's eligibility to receive an accommodation payment pursuant to proposed paragraph (e) of Exchange Rule 527. The Exchange will also require each Member to maintain books and records that detail the nature and amount of these losses. [^18]
[^18] Nasdaq included similar requirements in its accommodation policy and rule text related to the Facebook IPO system issues. *See* Nasdaq Rules, Equity 2, Section 17(b)(3)(I)(i).
Proposed subparagraph (e)(4) of Exchange Rule 527 will provide that all payments to Members under proposed paragraph (e) will be contingent upon the execution and delivery to the Exchange of a release by the Member of all claims by it or its affiliates [^19] against the Exchange or its affiliates for losses that arise out of, are associated with, or relate in any way to the Operational Error or to any actions or omissions related in any way to the Operational Error. Failure to provide the required release within 14 calendar days after the effective date of the rule proposal described in proposed subparagraph (e)(2) will void the Member's eligibility to receive an accommodation payment pursuant to this proposed paragraph (e). The purpose of imposing the release requirement notwithstanding the limitations of liability and immunities, which apply in any event pursuant to the Exchange's rules and agreements and/or otherwise as a matter of law, are to avoid the disruption and expense of unnecessary litigation in connection with the June 3, 2025 Operational Error and to ensure equal treatment of all claimants. [^20]
[^19] The term “affiliate” of or person “affiliated with” another person means a person who, directly, or indirectly, controls, is controlled by, or is under common control with, such other person. *See* Exchange Rule 100.
[^20] Nasdaq also included a similar release requirement in its accommodation policy and rule text related to the Facebook IPO system issues. *See* Nasdaq Rules, Equity 2, Section 17(b)(3)(H).
The accommodation payment policy proposed herein is a voluntary step taken by the Exchange to provide a substantial and rare accommodation to its Members and their customers, and participation in the program is likewise voluntary on the part of Members. The Exchange believes this type of occurrence warrants the establishment of an accommodation plan because, prior to the Operational Error, neither the Exchange nor any of its affiliates experienced a systems issue similar to that of the Operational Error. The Exchange believes that it would be inequitable to approve the Exchange's voluntary program without also allowing it to establish conditions that promote certainty and finality. [^21]
[^21]*See* Securities Exchange Act Release No. 69216 (March 22, 2013), 78 FR 19040 (March 28, 2013) (SR-NASDAQ-2012-090). In the approval order for the accommodation plan that Nasdaq proposed for its systems issues related to the Facebook IPO, the Commission approved similar conditions as proposed herein in order for Nasdaq members to be compensated for their claims.
The Exchange notes that it has received all claims that apply to the Operational Error and that no new additional claims will be accepted, subject to any final adjustments due to late discovery up to the time of payment of such claims. As described above, immediately following the June 3, 2025 Operational Error, the Exchange's Regulatory Operations Department spoke to each Member to discuss the Operational Error, the Exchange's proposed method of remedying trades based on erroneous simulation/testing environment data and the manner in which Members should submit claims for compensation. The Exchange independently verified each Member's claim and confirmed the loss amount with each Member prior to submitting this rule filing. The Exchange believes its proposal is designed to implement a fair and equitable accommodation policy that takes into account the impacts of the Operational Error on the investing public and Exchange Members.
**2. Statutory Basis**
The Exchange believes that the proposed rule change is consistent with Section 6(b) of the Act, [^22] in general, and furthers the objectives of Section 6(b)(5) of the Act, [^23] in particular, in that it is designed to prevent fraudulent and manipulative acts and practices, promote just and equitable principles of trade, foster cooperation and coordination with persons engaged in regulating, clearing, settling, processing information with respect to, and facilitating transactions in securities, 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. The Exchange also believes the proposed rule change is consistent with the Section 6(b)(5) [^24] requirement that the rules of an exchange not be designed to permit unfair discrimination between customers, issuers, brokers, or dealers.
[^22] 15 U.S.C. 78f(b).
[^23] 15 U.S.C. 78f(b)(5).
[^24]*Id.*
The Exchange believes that the proposal to expand its accommodation policy in this unique set of circumstances will balance several important goals in keeping with the foregoing statutory objectives. First, the Exchange acknowledges that the June 3, 2025 Operational Error had an impact on certain of its Members and their customers. As a result, the Exchange believes that the public interest would be served by an accommodation policy that quantifies and provides compensation for customer losses that were directly attributable to those system issues in an objectively discernible manner. Specifically, the Exchange believes that the public interest would be served by the Exchange making accommodation payments in excess of its limitation of liability rules to fully compensate Members that provided details regarding their claimed losses as a result of the Operational Error in an objectively discernible manner. The Exchange further believes that the public interest would be served by the Exchange providing as an accommodation the loss differential for the trade execution canceled by MIAX Sapphire and the replacement trade—that is the difference between the price that was expected upon execution on MIAX Sapphire during the timeframe of the Operational Error and the subsequent execution price for the replacement trade that was actually obtained on the Exchange or at an away-exchange.
Second, the Exchange believes that it is important to recognize the regulatory policy objectives underlying Exchange Rule 527 and ensure that they are not compromised. Hundreds of billions of dollars (or more) of securities transactions are matched through the systems of the Exchange and other exchanges every day. Through the operation of those systems, exchanges provide invaluable services in support of capital formation, price discovery, and investor protection. If exchanges could be called upon to bear all costs associated with system malfunctions and the varying reactions of market participants taken in their wake, the potential would exist for a single catastrophic event to bankrupt one or multiple exchanges, with attendant consequences for investor confidence and macroeconomic stability. Alternatively, the cost of providing exchange services would have to rise dramatically for all investors to cover this material and new risk. [^25] In addition, exchanges would be less inclined to implement innovative systems [^26] consistent with the goals of Section 6(b)(5) of the Act. [^27] Accordingly, the Commission has recognized that it is consistent with the purposes of the Act for a self-regulatory organization to limit its liability with respect to the use of such facilities by its members through rules such as Exchange Rule 527.

Moreover, if the potential for such catastrophic losses existed, as noted above, it would need to be reflected in the fees charged by exchanges to market participants in a manner that is not currently the case, making trading more expensive for all investors all the time. Rather, as the Commission has recognized, provisions such as Exchange Rule 527 reflect the view that risks associated with system malfunctions should be allocated among all exchange members, rather than being borne solely by the exchange. Indeed, this view is consistently reflected in the limitation of liability rules common among United States exchanges. [^29] This view is also reflected in the Exchange's proposal to condition any accommodation payment on the execution of a release of claims against MIAX Sapphire for the Operational Error experienced on June 3, 2025, because this condition is aimed at avoiding unnecessary litigation and ensuring equal treatment of all claimants.

The Exchange further believes that, consistent with Section 6(b)(5) of the Act, [^30] its proposal will promote just and equitable principles of trade and protect investors and the public interest by establishing a fair process through which affected Members may be compensated for the claims they submitted, which losses will be fully covered by the proposed accommodation policy. The Exchange believes that this filing will enhance the transparency of the process to compensate Members for their losses. The Exchange further believes that its proposed process for distributing accommodation payments will benefit investors and promote the public interest by providing incentives for Members to use accommodation funds for the benefit of investors. Specifically, the Exchange believes that its proposal will benefit investors and promote the public interest by requiring a claimant to submit to the Exchange an attestation detailing the compensation the Member has provided or will provide to its customers, and detailing the extent to which the Member incurred the losses covered by the proposed accommodation payment when trading for its own account.
[^30] 15 U.S.C. 78f(b)(5).
As described above, this type of proposal is not without precedent and is based on the accommodation plan implemented by Nasdaq in 2012 for system difficulties in the Nasdaq halt and imbalance cross process in connection with the IPO of Facebook. [^31]

**B. Self-Regulatory Organization's Statement on Burden on Competition**
The proposed rule change would not impose any burden on competition. The proposed rule change is designed to promote fairness in the marketplace by providing compensation to Members and their customers that experienced a loss as a result of the June 3, 2025 Operational Error. The Exchange believes that the proposed rule change will not burden intra-market competition because all Members would be subject to the same standards and requirements to receive accommodation payments as set forth in proposed Exchange Rule 527(e). The Exchange believes that the proposed rule change will not burden inter-market competition because the proposed rule change is not designed to address any competitive issues.
