A report dated October 20, 2026, stated that the U.S. Securities and Exchange Commission had conditionally approved five securities exchanges—24X, Cboe EDGX, MEMX, Nasdaq, and NYSE Arca—to extend trading hours. The five exchanges plan to launch a trading schedule of 23 hours per day, five days per week, on December 6. To support the extended trading, the relevant systems of the Securities Information Processors (SIPs), National Securities Clearing Corporation, and FINRA will also extend their operating hours. Broker-dealers will need to simultaneously adjust customer disclosures, trading controls, corporate action trading-halt arrangements, and staffing, and conduct cross-system testing. The report did not state whether the plan had received final approval or whether it would be implemented as scheduled.
