The Securities and Exchange Commission said on September 1, 2026 that it would hold a roundtable on preparations for 24-hour trading on September 17, at its Washington headquarters. The event addresses a shift that would change how investors think about pre-market movers and after-hours news: when trading never fully stops, there is less of a clear “before the open” window in which overnight developments get priced.
The agenda has three panels. The first covers preparedness for a 24-hour market, the second resiliency, and the third the expected impacts and next steps. The roundtable runs from 10 a.m. to 4 p.m. Eastern, and the SEC said it would be open to the public and webcast live.
The participant list spans most of the trading chain. Exchanges and trading venues on the program include NYSE, Nasdaq, Cboe, MEMX and OTC Markets Group. Brokers and trading firms include Robinhood, Schwab, Interactive Brokers, DriveWealth, Virtu Financial, Jane Street and Citadel Securities. Asset managers BlackRock, State Street and Invesco are represented, along with banks and custodians including UBS, Citi, BNP Paribas and BNY Pershing. Post-trade and oversight perspectives come from DTCC and FINRA, and technology from Exegy. Samsung also appears on the list.
The timing reflects work already approved. Earlier in 2026 the SEC approved Nasdaq’s plan to move to 23-hour weekday trading and approved changes allowing the consolidated data feeds to run overnight, with a target implementation date of December 6, 2026. The roundtable brings those threads together with the operational questions that sit beneath them: clearing and settlement around the clock, staffing, surveillance, system maintenance windows and how firms recover from outages when there is no overnight downtime.
For investors, the practical questions are about liquidity and price quality at odd hours, how brokers disclose overnight risks, and how corporate news releases, which have traditionally been timed for before the open or after the close, fit into a continuous market.
What to watch: any statements or follow-up requests for comment after the roundtable, and whether the agency signals changes to clearing, settlement or disclosure expectations before overnight trading on the national exchanges begins.
