          - [Release No. 34-102338; File No. SR-MEMX-2025-01]

                    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 January 22, 2025, MEMX LLC (“Exchange”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Item I below, which Item has been substantially 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 amend Rule 21.7 related to the Exchange's opening procedures on MEMX Options. Specifically, the Exchange proposes to open options, other than index options, for trading after the System's observation after 9:30 a.m. Eastern Time of both: (i) the first disseminated transaction on the primary listing market in the securities underlying the options, and (ii) the Limit Up-Limit Down (“LULD”) price bands applicable to the securities underlying the options as disseminated by the applicable Securities Information Processor (“SIP”). The Exchange currently opens options, other than index options, for                           ( print page 9267)                        trading following the first print disseminated pursuant to an effective national market system plan.                

                    The proposed rule change, including the Exchange's statement of the purpose of, and statutory basis for, the proposed rule change is available on the Exchange's website at                     *https://info.memxtrading.com/​regulation/​rules-and-filings/​*                     and on the Commission's website at                     *https://www.sec.gov/​rules-regulations/​self-regulatory-organization-rulemaking/​national-securities-exchanges?​file_​number=​SR-MEMX-2025-01.*

## II. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action

                    The Exchange has filed the proposed rule change pursuant to Section 19(b)(3)(A) of the Act [3]                                          and Rule 19b-4(f)(6) [4]                                          thereunder. Because the foregoing proposed rule change does not: (i) significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; or (iii) become operative for 30 days from the date on which it was filed, or such shorter time as the Commission may designate, it has become effective pursuant to Section 19(b)(3)(A) of the Act [5]                                          and Rule 19b-4(f)(6) [6]                                          thereunder.                

                    A proposed rule change filed under Rule 19b-4(f)(6) [7]                                          normally does not become operative prior to 30 days after the date of the filing. However, pursuant to Rule 19b-4(f)(6)(iii),[8]                                          the Commission may designate a shorter time if such action is consistent with protection of investors and the public interest. The Exchange has asked the Commission to waive the 30-day operative delay so that the proposed rule change may become operative immediately upon filing. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest because it will align the Exchange's options opening with the opening price of the corresponding underlying security on its primary listing market. Accordingly, the Commission designates the proposed rule change to be operative upon filing.[9] 

At any time within 60 days of the filing of the proposed rule change, the Commission summarily may temporarily suspend such rule change if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of the Act. If the Commission takes such action, the Commission will institute proceedings to determine whether the proposed rule change should be approved or disapproved.

## III. Solicitation of Comments

                    Interested persons are invited to submit written data, views, and arguments concerning the foregoing, including whether the proposed rule change is consistent with the Act.[10]                                          Comments may be submitted electronically by using the Commission's internet comment form (                    *https://www.sec.gov/​rules-regulations/​self-regulatory-organization-rulemaking/​national-securities-exchanges?​file_​number=​SR-MEMX-2025-01*) or by sending an email to                     *rule-comments@sec.gov.*                     Please include file number SR-MEMX-2025-01 on the subject line.
