The SEC is set to hold a public roundtable on Sept. 17 on what it would take to keep U.S. stocks trading far beyond the traditional 9:30 a.m. to 4 p.m. Eastern Time session. The big question is not whether Wall Street likes the idea. It is whether the market plumbing can handle it without turning into a sleepy mess with expensive mistakes.
- SEC roundtable: Sept. 17 in Washington, D.C., streamed online
- Focus: market operations, resilience, investor protection
- Reality check: proposals are nearer to 23/5 than true nonstop trading
- Crypto pressure: always-on markets changed expectations
- Key distinction: tokenized equities are not the same as listed shares
SEC Chair Paul Atkins summed up the mood with a line that sounds almost too neat for Washington:
“We are moving towards a new day, and night, in the U.S. equity markets.”
That may be the slogan, but the real work is a lot less glamorous. The SEC sets September talks as 24-hour stock trading moves will center on overnight trading, market operations, system resilience, and investor protection. Translation: can the market stay fair, functional, and secure when the closing bell stops being the end of the day?
SEC Division of Trading and Markets director Jamie Selway has pointed to the practical issues that have to line up: market data, clearing, corporate actions, trade reporting, and investor protection. That is the unsexy core of the whole thing, and it matters more than the marketing.
Market data is the price and trade information that brokers and investors rely on. Clearing is the post-trade process that confirms and settles trades and helps manage counterparty risk. Trade reporting is the record of completed trades that gets sent through market systems and regulators. Corporate actions are events like dividends, splits, and mergers that have to be handled cleanly across the market. Surveillance is the monitoring that looks for manipulation, spoofing, and other abusive behavior.
In other words: if you extend trading hours without fixing the plumbing, you do not get a modern market. You get a longer one with more ways to break.
U.S. stocks already trade outside regular hours, but that is not the same as a fully continuous market. The current setup still revolves around the standard weekday session, with premarket and after-hours trading handled through a more limited and fragmented structure. What regulators and exchanges are now exploring is something closer to a near-continuous weekday market.
The distinction matters. A lot of people hear “24-hour trading” and picture stocks trading around the clock like crypto. That is the headline version. The practical version is more cautious: extended weekday sessions, not a magic switch that suddenly makes the U.S. equity market a true 24/7 machine.
Cboe’s proposal is a good example of that reality. The exchange filed to allow trading in equity securities and exchange-traded products for 23-hour trading for equity securities, with a new Overnight Trading Session and a one-hour daily break. The proposal was published in the Federal Register on April 15, 2026, and Cboe later filed Amendment No. 1 on May 26, 2026, which superseded the original proposal in its entirety.
Cboe says the plan is driven in part by growing demand from retail investors in the Asia-Pacific region, including Hong Kong, Japan, Korea, Singapore, and Australia. That makes sense. U.S. market hours are not exactly friendly if you live on the other side of the planet and do not enjoy setting alarms at absurd hours just to buy an ETF.
The exchange’s own figures show that demand is already there. Cboe reported that its Early Trading Session average daily volume increased 110% from January 2023 to February 2026, and 404% from January 2022 to February 2026. It also said Early Trading Session market share rose 258% between January 2023 and February 2026. Those are company-reported numbers, so they are not some holy market gospel, but they do show this is not a totally imaginary demand curve.
Nasdaq is also pursuing longer hours, with a plan to offer trading 24 hours a day, five days a week, subject to regulatory approval and industry readiness. The broader point is clear: exchanges are moving because investors are asking for more access, and because crypto already normalized the idea that markets do not have to go dark every evening.
That crypto comparison is real, but it should not be oversold. Crypto markets have traded continuously for years, including weekends and holidays. That proved nonstop trading is technically possible. It did not prove that nonstop trading is always efficient, orderly, or fair. Anyone who has tried to get a clean price on a thin Sunday night book knows the “always open” promise comes with plenty of garbage execution and volatility.
That is where the hard questions start.
More hours can mean more convenience and better access for global investors. They can also mean thinner liquidity, wider bid-ask spreads, and more uneven price discovery during the least active parts of the day. Liquidity is how easily an asset can be bought or sold without moving the price too much. The bid-ask spread is the gap between the highest price buyers are offering and the lowest price sellers are asking. When fewer traders are active, those spreads can widen and execution can get uglier fast.
So yes, longer hours can help investors react to news without waiting for the opening bell. They may also make it easier for people in different time zones to participate on their own schedule. That is a real benefit. But more access is not automatically better if the market is thinner, more volatile, and more vulnerable to sloppy fills or manipulation when most participants are asleep.
That is why the SEC’s focus on system resilience is not just bureaucratic jargon. If exchanges stay open longer, brokers, clearing firms, market data providers, and surveillance systems have to stay ready too. Outages become harder to manage when the market has almost no meaningful downtime. Maintenance windows shrink. Staff schedules get harder. And if something breaks at 2 a.m., there are fewer people around to catch it quickly.
There is also the investor protection angle. Continuous or near-continuous trading raises the stakes for fair access, trade reporting, and monitoring for abuse. Overnight sessions can be especially vulnerable because they often have lighter participation. That creates openings for bad actors to move prices around in ways that would be harder during deeper daytime liquidity. No one should pretend that more hours automatically means a more democratic market.
The SEC is not handing out a launch date here. This is a public roundtable, not a final green light. The agency has opened a public comment file and said it will publish the agenda and speaker list before Sept. 17. That is the SEC doing what the SEC does best: asking whether the giant machine can keep functioning once someone decides the market should stop clocking out at 4 p.m.
The conversation also matters because it is not limited to traditional exchanges. The rise of tokenized equities has added another layer of confusion, and a lot of people still blur the line between tokenized exposure and real listed shares. They are not the same thing.
Tokenized equities are blockchain-based instruments that represent or track stocks, but they may differ from exchange-listed shares in ownership, custody, shareholder rights, dividend treatment, and regulatory status. In plain English: buying a token that tracks a stock is not necessarily the same as holding the actual stock through the regulated market structure.
That distinction is important. Binance has launched bStocks with continuous trading for tokenized U.S. equities. Franklin Templeton and Ondo have also launched tokenized investment products accessible through crypto wallets around the clock to eligible users outside the U.S. Those products are interesting, and in some cases useful. But they are not a substitute for listed shares, and they should not be sold as if they were the same beast wearing a different costume.
This is where the crypto world and traditional finance keep bumping into each other. Crypto showed that markets can stay open all the time. It also showed that 24/7 access does not magically solve market quality, fair pricing, or manipulation risk. Traditional markets are now trying to borrow the convenience without importing the chaos wholesale. Good luck with that, but at least the attempt is happening in the open, with regulators forcing the boring questions into the daylight.
For investors, the real issue is simple: will longer hours improve execution and access, or just stretch the same market problems over more of the day? If liquidity is weak, spreads widen, and the infrastructure is shaky, then “more trading hours” is just a longer route to the same bad trade.
What readers should be asking
-
Is 24-hour U.S. stock trading happening now?
No. The SEC is discussing what would be required, and exchanges are filing plans, but this is still an infrastructure and regulatory process. -
Is Cboe proposing true nonstop trading?
No. The filed proposal calls for 23 hours per day, five days per week, with a one-hour daily break. -
Why is the SEC involved?
Because longer hours affect market data, clearing, trade reporting, corporate actions, resilience, surveillance, and investor protection. This is a market-structure issue, not just a trading-hours tweak. -
What is the biggest risk?
Thin liquidity. Overnight sessions can bring wider spreads, worse pricing, and more room for volatility or manipulation. -
Are tokenized stocks the same as real stocks?
No. They can track or represent equity exposure, but they do not necessarily carry the same legal rights, custody protections, or exchange status as listed shares. -
Why does crypto matter here?
Because crypto markets have traded continuously for years, and that has changed investor expectations. Traditional markets are responding, but they still have to play by stricter rules.
More hours are easy to promise. A better market is harder to build. That is the test now.
Elsewhere, the same push toward market modernization is showing up in exchange rulemaking and tokenization debates, from extended trading hours in options to broader efforts like extended-hours trading and industry arguments over Extended Trading Hours. The same pressure is also bleeding into other asset classes, with projects such as Cboe Files for Franklin Templeton’s Solana ETF: A Step and broader policy fights like SEC May Scrap Stock Trade Rules, Clearing Path for and Nasdaq Pushes Tokenized Equities With Kraken as Bending forcing the same ugly but necessary question: where does convenience end and regulatory nonsense begin?
And because the finance world loves pretending old ideas are brand new, even traditional exchanges are trying to dress up the shift with sleek branding, from Advancements in Artificial Intelligence: Transforming style marketing to the usual “innovation” jargon that makes everyone sound smarter than they are. Spoiler: a fancy pitch deck does not fix weak overnight liquidity.
