Effective August 10, 2026, The Nasdaq Stock Market (“Nasdaq”), Nasdaq Texas (“NTX”) and Nasdaq PSX (“PSX”) (collectively, “Nasdaq Exchanges” or "Exchanges") will make operative certain previously approved amendments to their respective trading halt rules that are the result of coordinated work by the Nasdaq Exchanges and the other SROs to establish common criteria and procedures for halting and resuming trading in equity securities when regulatory or operational issues arise. The amendments incorporate several definitions and concepts from the amended Nasdaq UTP Plan and are intended to promote consistent and transparent treatment of events that may affect multiple exchanges. The Nasdaq Exchanges believe that these common standards will help the SROs maintain fair and orderly markets. The Exchanges will continue to retain discretion in certain instances as to whether and how to handle halts.

Once operative as scheduled, the updated rules include the following changes:

  • Clarifies the situations that form the basis of a Primary Listing Market’s authority to declare a Regulatory Halt: (1) as provided by the SIP Plans; (2) discretionary Regulatory Halts; and (3) mandatory Regulatory Halts;
  • Provides detailed and consistent rules on how a Primary Listing Market will initiate and resume trading in the event of a Regulatory Halt and clarifies the obligations of other exchanges under the circumstances; and
  • Clarifies the discretion afforded to the Nasdaq Exchanges to impose an Operational Halt that applies only to that exchange's market.

For additional information, please find Nasdaq Exchanges’ rule filings in SR-NASDAQ-2022-017_Amendment_1, SR-BX-2023-007 and SR-Phlx-2022-49. See also Nasdaq UTP Amendment 50.
