The US Securities and Exchange Commission will convene a public roundtable on September 17 to examine the shift toward continuous trading in American equity markets. The session will take place at the agency’s headquarters in Washington and will address preparations for overnight sessions as well as operational and resilience requirements in a 24-hour environment.

Commission leadership indicated that US equity markets are advancing toward extended trading periods that include nighttime hours. The goal is closer alignment with jurisdictions that already operate continuous sessions.

The discussion occurs as several major exchanges expand or prepare longer trading windows. Nasdaq began discussions with US regulators in March on offering five-day-a-week, 24-hour trading, with a target launch in the second half of 2026 subject to regulatory clearance. The London Stock Exchange is preparing a nighttime trading venue for early 2027. Other platforms, including Cboe, are likewise advancing plans for extended hours, a development that would give retail participants access previously limited largely to cryptocurrency markets.
