BOX Exchange files immediate rule change to remove Mini Options references

On October 23, 2026, BOX Exchange LLC filed a proposed rule change with the Securities and Exchange Commission under Section 19(b)(1) of the Securities Exchange Act of 1934 and Rule 19b-4. The filing, identified as File No. SR-BOX-2026-22 and Release No. 34-106828, is effective immediately upon filing.

The Exchange seeks to delete references to Mini Options and Jumbo SPY Options from its rulebook, marking the affected provisions as "Reserved." Amendments target IM-3120-3, IM-3120-4, Rule 5050, IM-5050-7, IM-5050-10, IM-6010-1, Rule 6040, Rule 6090, Rule 7040, Rule 7110, and Rule 7240, among others, to reflect that these products are no longer listed or have never been listed on the Exchange.

In addition, the proposal includes a series of technical, non-substantive updates to internal cross-references. Examples include correcting references in Rule 5030(h)(1) to Rule 5020(h)(1), updating Rule 7130(b)(1) to cite Rule 8040(c) and (d), and revising Rule 7620(e) to reference Rule 7040(a) and (b). The Exchange states these changes are intended solely to improve accuracy and clarity without altering rule operation.

The Exchange cites the statutory authority of Section 6(b) and Section 6(b)(5) of the Act, asserting that the amendments promote just and equitable principles of trade, remove impediments to a free market, and protect investors and the public interest.

The Commission is publishing this notice to solicit comments from interested persons. Comments may be submitted in accordance with the procedures outlined in the filing, which is available at the Exchange's principal office and on its website at https://rules.boxexchange.com/rulefilings.
