The U.S. Securities and Exchange Commission announced a public roundtable for Sept. 17, 2026, on the shift toward 24-hour trading in U.S. equity markets. The discussion will focus on what is needed to support overnight trading, how operations and market resiliency would function in a round-the-clock market, and the main opportunities and challenges tied to longer trading hours. Chairman Paul S. Atkins described the event in the context of expanding overnight trading and the prospect of bringing U.S. equity markets closer to markets that already trade continuously, while balancing that expansion with investor and customer protections. The roundtable will be held at the SEC's headquarters and streamed live on SEC.gov, with a recording to be posted later. The SEC said agenda and speaker information will be published before the event.
