The US Securities and Exchange Commission has published the agenda and speaker list for its roundtable on preparations for 24-hour trading, scheduled for 17 September 2026. The event brings together regulators, exchanges, broker-dealers, and market infrastructure providers to evaluate operational readiness and systemic risks.
Event Structure and Public Access
The roundtable will take place at the SEC headquarters in Washington, D.C., running from 10:00 to 16:00 ET, with doors opening at 09:00 ET. The session is open to the public, with in-person visitors required to register in advance and complete security screening.
For virtual participants, registration is not required. The SEC will stream a live webcast on its public website on 17 September 2026, with an archived recording made available for later viewing.
Roundtable Panels and Core Objectives
The day begins with opening remarks from the SEC Chairman, Commissioners, and Jamie Selway, Director of the SEC Division of Trading and Markets. A data presentation by Dan Mathisson of the Office of Analytics and Research will follow, introducing market research relevant to extended operating hours.
Three structured panels will address specific dimensions of continuous trading:
Panel One focuses on market preparedness, examining broker-dealer and exchange readiness, overnight market surveillance, closing price determination, clearance and settlement processes, and investor protection safeguards.
Panel Two covers operational resiliency, addressing system capacity, Regulation SCI obligations, failover protocols, market-data continuity, shortened technical maintenance windows, cybersecurity, and overnight staffing models.
Panel Three considers long-term market structure impacts, evaluating liquidity distribution, capital formation, potential effects on corporate issuers, and infrastructure requirements for potential future expansion towards 24/7 trading.
