The SEC wants to keep the markets open all night. The agency confirmed it will host a roundtable on September 17, 2026, focused entirely on what it would actually take to move U.S. equity markets to a 24-hour trading model — and whether the industry is anywhere close to ready.
It’s a bigger deal than it sounds. Right now, U.S. stock exchanges operate on a pretty narrow window compared to global peers. Many international markets already run continuous or near-continuous sessions, and there’s been growing pressure — especially from retail investors who trade crypto around the clock — to bring equities in line with that reality. The SEC seems to be taking that pressure seriously, at least seriously enough to get everyone in a room and hash it out. The roundtable will pull in representatives from exchanges, brokerage firms, and other key market players. They’ll be looking at three broad areas: technology, regulatory frameworks, and how market participants themselves would need to change their behavior to make overnight trading actually work.
No specific implementation timeline.
That’s worth sitting with for a second. The SEC hasn’t put a date on any of this beyond September 17. No proposal, no rulemaking, no pilot program announced. Just a roundtable. So we’re basically at the very beginning of what could be a long process — or could go nowhere, depending on what comes out of the discussions.
What the SEC Is Actually Examining
The operational questions here are genuinely hard. Running a market for 24 hours isn’t just flipping a switch. Trading platforms would need significant upgrades to handle continuous load without degrading. Clearinghouses and settlement systems — which are already under strain during peak hours — would face entirely new demands overnight when staffing is thin and liquidity is typically low. The SEC wants to hear from the people running these systems about how ready they actually are, and what it would cost to get there.
Liquidity is probably the thorniest issue. During traditional off-hours, bid-ask spreads widen, volume drops, and prices can swing on relatively small orders. Extending official trading hours doesn’t automatically fix that. If institutional desks aren’t staffed and market makers aren’t quoting aggressively at 3 a.m., retail investors trading overnight might actually face worse conditions than they’d expect. The roundtable is supposed to dig into exactly that kind of tension — the gap between the appeal of 24-hour access and the messiness of what it looks like in practice.
Regulatory frameworks would need work too. Existing rules around order handling, best execution, and market surveillance were built for a session-based model. Continuous trading would probably require some of those rules to be rewritten, or at minimum reinterpreted. Participants at the roundtable are expected to get into the specifics of which rules need updating and how fast that could realistically happen.
Crypto’s Shadow Over This Conversation
It’s hard to ignore the context here. Crypto markets have run 24/7 for years, and that’s partly why retail traders have grown comfortable with the idea of buying and selling assets at any hour. Bitcoin doesn’t close. Ethereum doesn’t close. And a generation of investors has gotten used to that. The SEC’s interest in 24-hour equities trading isn’t happening in a vacuum — it’s at least partly a response to the competitive pressure that crypto markets have put on traditional finance.
Whether that pressure is the main driver or just background noise isn’t clear yet. But it’s probably not a coincidence that the SEC is moving on this now, after years of watching crypto platforms attract retail volume that might otherwise have gone to equities.
The agency also seems to be looking at how other countries have handled similar transitions. Several international markets have expanded their hours over the past decade, and the SEC wants to pull lessons from those experiences — what worked, what didn’t, what they’d do differently.
What Comes Out of September
After the roundtable, the SEC may move toward further consultations or float actual regulatory proposals. Or it might decide the obstacles are too significant for now and table the idea. No details on next steps have been shared beyond the event itself.
What’s clear is that the agency sees extended trading hours as a real possibility worth examining — not a fringe idea. Getting exchanges, brokers, and regulators in the same room on September 17 is a concrete first step, even if everything after that stays murky.
The roundtable agenda hasn’t been published yet.
