SEC Sets Agenda for 24-Hour Trading Roundtable

The Securities and Exchange Commission has published the agenda and panelist lineup for its September 17, 2026 roundtable on preparations for 24-hour trading. The event is scheduled for 10 a.m. to 4 p.m. ET at the SEC’s Washington, D.C. headquarters and will be webcast.

The first panel will focus on launch readiness for a 24-hour market, including exchange and broker-dealer preparation, overnight surveillance, closing-price processes, clearance and settlement changes, and investor-protection practices. Panelists include representatives from Robinhood, NYSE, Cboe, FINRA, UBS, BNY Pershing, Virtu Financial, BlackRock, and other market participants.

The second panel will cover resiliency, including systems readiness, Regulation SCI considerations, failover planning, capacity, market-data continuity, cybersecurity, staffing models, and reduced maintenance windows. A third panel will discuss expected effects on liquidity, capital formation, issuers, and possible next steps toward broader 24x7 trading.

Why it matters

For active equity and options traders, 24-hour trading is not just a longer session. It raises practical questions about spreads, depth, clearing cycles, overnight risk controls, market-data quality, order handling, and how brokers support customers when traditional market infrastructure is offline or thinly staffed.

The roster also shows that the SEC is looking across exchanges, broker-dealers, clearing providers, wholesalers, asset managers, and market-data vendors rather than treating overnight trading as a single-platform issue.
