The event, scheduled at the SEC’s Washington headquarters, will bring together regulators, industry participants, and the public to discuss preparations for extending trading hours beyond the traditional session.SEC Sets Date for 24-Hour Trading DiscussionThe Securities and Exchange Commission confirmed that the roundtable will take place on September 17 at its headquarters located at 100 F Street, N.E., Washington, D.C. The session will focus on three core areas tied to 24-hour trading: preparations needed to support overnight sessions, operational resiliency across a continuous market, and the broader opportunities and challenges tied to expansion.SEC to Host Roundtable on Preparations for 24-Hour Trading in U.S. EquitiesU.S. Securities and Exchange Commission (SEC) announced it will host a public roundtable on September 17, 2026, at its Washington headquarters to discuss moving towards 24-hour trading in the U.S. equity… pic.twitter.com/6nUOe0RRwS— Wu Blockchain (@WuBlockchain) July 23, 2026SEC Chairman Paul S. Atkins said the agency is “moving towards a new day—and night” in U.S. equity markets. He added that expanding into overnight hours would let U.S. markets align with other global venues that already operate continuously. Atkins framed the shift as part of a natural evolution rather than a sudden change for market participants.The chairman also noted that regulators must weigh the benefits of round-the-clock access against the need to maintain strong investor and customer protections. This balance is expected to shape much of the roundtable’s agenda once further details are released. The SEC has not yet published a full speaker list or discussion schedule for the event.Officials confirmed the roundtable will be open to the public and streamed live on SEC.gov, with a recording made available afterward for those unable to attend. Visitors planning to attend in person should expect security screening, and the agency cautioned that in-person attendance may be limited depending on capacity.Public Comment Process Opens Ahead of RoundtableAlongside the roundtable announcement, the SEC opened a public comment period for anyone with views on 24-hour trading. Members of the public can submit feedback either electronically or on paper, though the agency asked that commenters choose only one submission method to avoid duplication.All comments tied to the 24-hour trading discussion will become part of the public record once submitted. The SEC confirmed that submissions will be posted on its website exactly as received, without edits or redactions applied by staff.Because personal identifying information will not be removed from submissions, the agency urged commenters to share only what they are comfortable making public. Submissions must reference File Number 4-913, and commenters using email are asked to include that file number directly in the subject line.The comment period gives market participants, exchanges, and everyday investors a formal channel to weigh in before regulators finalize their approach to extended trading hours. With the roundtable still weeks away, further updates on agenda items and confirmed speakers are expected as September approaches.The post SEC Sets September 17 Roundtable to Discuss 24-Hour Trading in U.S. Equity Markets appeared first on Blockonomi.
