SEC Sets September Roundtable on 24-Hour Equity Trading

The U.S. Securities and Exchange Commission said on July 23, 2026 that it will convene a public roundtable on September 17 to discuss moving U.S. equity markets toward 24-hour trading, according to the agency's press release.

The stated scope is preparatory rather than a rule proposal. The SEC said the session will cover "preparations to support overnight trading, operations and resiliency in a 24-hour market, and opportunities and challenges for expansion." No decision, rulemaking, or timeline for round-the-clock trading was announced.

SEC Chairman Paul S. Atkins framed the move in continuous-market terms. "We are moving towards a new day – and night – in the U.S. equity markets," he said in the release, adding that he was "excited at the prospect of U.S. equity markets aligning with those markets that already trade continuously" while "balancing round-the-clock trading with all-important investor and customer protections."

The roundtable will be held at SEC headquarters, 100 F Street N.E., Washington, D.C., and streamed live on SEC.gov, with a recording posted later. The agency said in-person seating may be limited and that an agenda and speaker list will be published before the event. The public can submit written comments — electronically via the SEC comment form or by email to rule-comments@sec.gov, or on paper to the Commission's Secretary — under File Number 4-913. The SEC warned that all submissions are posted publicly without redaction, including any personal information.

The real-world read

This is a discussion, not a decision. The SEC announced a date and a scope; it did not propose a rule, set a start date, or endorse any specific 24-hour venue. Atkins' "new day – and night" line is the chairman's framing, not a policy commitment, and his own caveat — "balancing round-the-clock trading with all-important investor and customer protections" — flags the open questions the roundtable exists to surface: who provides liquidity overnight, how outages are handled when markets never close, and how retail investors are protected in thin off-hours sessions.

Worth noting what the announcement doesn't say: no named speakers or agenda yet, no cost-benefit analysis, and no position on the private overnight-trading platforms already operating around the edges of the regulated market. The framing that U.S. markets should "align" with continuously-traded ones is an argument, not a settled fact — and it's the SEC's own.

Opinion, and whose

The characterization of 24-hour trading as a "new day" for U.S. equities and a benefit worth pursuing is Chairman Atkins' view, per the SEC release. No independent market participants, exchanges, or investor advocates are quoted, so the announcement contains only the regulator's own optimism.
