          - [Release No. 34-101191; File No. SR-MIAX-2024-38]

                    Pursuant to the provisions of 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 September 17, 2024, Miami International Securities Exchange, LLC (“MIAX” 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.                

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

The Exchange proposes to make a number of minor, non-substantive edits to Exchange's Rulebook and delete all references to mini-options in the Rulebook.

                    The text of the proposed rule change is available on the Exchange's website at                     *https://www.miaxglobal.com/​markets/​us-options/​miax-options/​rule-filings,*                     at MIAX's principal office, and at the Commission's Public Reference Room.                

## 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

#### Proposal To Amend Exchange Rule 100

The Exchange proposes to amend Exchange Rule 100 to make minor, non-substantive edits and clarifying changes to provide accuracy and precision within the rule text.

                    Specifically, the Exchange proposes to amend the definition of Market Makers [3]                                          in Exchange Rule 100 to move the comma after “Lead Market Makers” from outside to inside the quotation marks for grammatical correctness and clarity in the rule text. Additionally, the Exchange proposes to add a comma before the conjunction “and” (                    *i.e.*                     between “Primary Lead Market Makers” and “Registered Market Makers”), where the comma will be placed inside the closing quotation mark. Accordingly, with the proposed changes, the definition of Market Makers in Exchange Rule 100 will read as follows:                

The term “Market Makers” refers to “Lead Market Makers,” “Primary Lead Market Makers,” and “Registered Market Makers” collectively.

#### Proposal To Amend Interpretations and Policies .01 of Exchange Rule 521

The Exchange proposes to amend Interpretations and Policies .01 of Exchange Rule 521 to make a minor, non-substantive edit to provide accuracy and precision within the rule text.

                    Specifically, the Exchange proposes to amend Interpretations and Policies .01                           ( print page 79986)                        of Exchange Rule 521 to add a closing parenthesis at the end of the first sentence for grammatical correctness and clarity in the rule text. Accordingly, with the proposed changes, the Interpretations and Policies .01 of Exchange Rule 521 will read as follows:                

.01 Limit Up-Limit Down State. An execution will not be subject to review as an Obvious Error or Catastrophic Error pursuant to paragraph (c) or (d) of this Rule if it occurred while the underlying security was in a “Limit State” or “Straddle State,” as defined in the Regulation NMS Plan to Address Extraordinary Market Volatility (the “Limit Up-Limit Down Plan” or the “Plan”). Nothing in this provision shall prevent such execution from being reviewed on an Official's own motion pursuant to sub-paragraph (c)(3) of this Rule, or a bust or adjust pursuant to paragraphs (e) through (k) of this Rule.

#### Proposal To Amend Interpretations and Policies .02 of Exchange Rule 1809

                    The Exchange proposes to amend Interpretations and Policies .02 of Exchange Rule 1809 to make a minor, clarifying change to provide accuracy and precision within the rule text. Interpretation and Policy .02 of Exchange Rule 1809 discusses the Quarterly Options Series [4]                                          Program and that the Exchange may list Quarterly Options Series for index options.                

                    Specifically, the Exchange proposes to amend Interpretations and Policies .02 of Exchange Rule 1809 to delete “pilot” at the end of the last sentence. The Exchange notes that other exchanges have permanently established quarterly options series programs.[5]                                          Accordingly, with the proposed changes, Interpretations and Policies .02 of Exchange Rule 1809 will read as follows:                

.02 Quarterly Options Series Program: Notwithstanding the restriction in Rule 1809(a)(3), the Exchange may list and trade options series that expire at the close of business on the last business day of a calendar quarter (“Quarterly Options Series”). The Exchange may list Quarterly Options Series for up to five (5) currently listed options classes that are either index options or options on exchange traded funds (“ETFs”). In addition, the Exchange may also list Quarterly Options Series on any options classes that are selected by other securities exchanges that employ a similar program under their respective rules.

#### Proposal To Delete All References to Mini-Options

                    The Exchange proposes to delete all outdated references to mini-options in the rule text.[6]                                          On April 17, 2013, the Exchange began listing and trading mini-options that were options contracts on a select number of high-priced and actively traded securities, each with a unit of trading ten times lower than that of standard-sized options contracts.[7]                                          Mini-options never gained significant market acceptance and have not achieved the expected level of traction or success in its target market. Accordingly, all mini-options were delisted several years ago and the Exchange does not have plans to re-list them in the foreseeable future. As the Exchange no longer offers mini-option contracts, the Exchange proposes to delete all references to mini-options to provide greater clarity to Members [8]                                          and the public regarding the Exchange's offerings and Rulebook. The Exchange also notes that other exchanges filed similar proposals to delete references to mini-options.[9] 

Specifically, the Exchange proposes to delete the content in Interpretations and Policies .03 of Exchange Rule 307 and then insert “Reserved” so as to keep the remainder of the Rulebook as currently formatted. The Exchange proposes to delete the content in Interpretations and Policies .08 of Exchange Rule 404 and then insert “Reserved” so as to keep the remainder of the Rulebook as currently formatted. The Exchange proposes to delete the content in subparagraph (c) of Exchange Rule 509 and then insert “Reserved” so as to keep the remainder of the Rulebook as currently formatted. The Exchange proposes to delete the content in Interpretations and Policies .02 of Exchange Rule 510 and then insert “Reserved” so as to keep the remainder of the Rulebook as currently formatted. The Exchange proposes to delete “or 5,000 mini-option contracts” at the end of subparagraph (b)(1)(i) of Exchange Rule 515A. The Exchange proposes to delete “or 10,000 mini-option contracts,” in the first sentence of subparagraph (j) of Exchange Rule 516. In addition, the Exchange proposes to delete the sentence that “Mini-options may only be part of a complex order that includes other mini-options.” in subparagraph (a)(5) of Exchange Rule 518.

#### 2. Statutory Basis

                    The Exchange believes that the proposed changes are consistent with Section 6(b) of the Act [10]                                          in general, and further the objectives of Section 6(b)(1) of the Act [11]                                          in particular, in that they are designed to enforce compliance by the Exchange's Members and persons associated with its Members, with the provisions of the rules of the Exchange. In particular, the Exchange believes that the proposed changes will provide greater clarity to Members and the public regarding the Exchange's Rulebook by correcting grammatical errors, removing obsolete rule text, and providing accuracy and consistency within the Exchange's Rulebook. The proposed changes will also make it easier for Members to interpret the Exchange's Rulebook.                

                    The Exchange believes that the proposed rule changes also further the objectives of Section 6(b)(5) of the Act. In particular, they are 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 mechanisms of a free and open market and a national market system and, in general, protect investors and the public interest. The Exchange believes the proposed changes promote just and equitable principles of trade and remove impediments to and perfect the mechanism of a free and open market and a national market system                           ( print page 79987)                        because the proposed rule changes will provide greater clarity to Members and the public regarding the Exchange's Rulebook by correcting grammatical errors and removing obsolete rule text. The proposed changes to remove obsolete rule text include the removal of outdated references to mini-options. Mini-options are no longer offered by the Exchange since mini-options failed to gain significant market acceptance and have not achieved the expected level of traction or success in its target market. Removing references to mini-options would render the rules more accurate and reduce potential investor confusion. It is in the public interest for the Exchange's Rulebook to be accurate and concise so as to eliminate the potential for confusion.                

### B. Self-Regulatory Organization's Statement on Burden on Competition

                    The Exchange does not believe that the proposed changes will impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Act. Specifically, the Exchange believes the proposed changes will not impose any burden on intra-market competition as there is no functional change to the Exchange's System [12]                                          and because the rules of the Exchange apply to all Members equally. The proposed rule changes will have no impact on competition as they are not designed to address any competitive issue but rather are designed to remedy minor, non-substantive issues and provide added clarity to the Exchange's Rulebook, including removing outdated references to mini-options that are no longer offered by the Exchange. Mini-options failed to gain significant market acceptance and have not achieved the expected level of traction or success in its target market, so the Exchange delisted all mini-options several years ago and does not have plans to re-list them in the foreseeable future.[13]                                          In addition, the Exchange does not believe the proposal will impose any burden on inter-market competition as the proposal does not address any competitive issues and is intended to protect investors by providing further transparency and accuracy regarding the Exchange's Rulebook.                

### 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

                    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 [14]                                          and subparagraph (f)(6) of Rule 19b-4 thereunder.[15] 

                    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) [16]                                          of the Act to determine whether the proposed rule change be approved or disapproved.
