Remember when the stock market had business hours? Those quaint 9:30 a.m. to 4 p.m. ET days are about to become a relic. Nasdaq just announced it’s filing with the SEC to launch 24-hour trading, five days a week. Yes, you read that right—the market could soon be open around the clock, Monday through Friday.
Here’s the pitch: Nasdaq President Tal Cohen says this move is all about access. Foreign investors currently hold $17 trillion in U.S. equities—that’s up 97% since 2019. But here’s the catch: when you’re sitting in Tokyo or London, waiting for the U.S. market to open feels like watching paint dry. Nasdaq wants to let global investors trade whenever it’s convenient for them, not just when it’s convenient for New York.
The numbers back up the demand. Over 56 ETFs tracking the Nasdaq 100 have launched in the last five years, and 98% of them came from outside the U.S. That’s not a coincidence—it’s a signal that international money is hungry for American stocks, and they want easier access.
Of course, nothing’s ever simple in finance. Nasdaq’s own survey of listed companies found that roughly half have serious reservations about this. Their main worry? Liquidity. When the market’s open 24/7, trading volume during overnight hours will be thinner than a startup’s profit margins. That means wider bid-ask spreads, higher volatility, and potentially gnarlier transaction costs. Not exactly a feature investors are begging for.
There’s also the infrastructure headache. U.S. markets process millions of messages per second. Adding 24-hour trading means coordinating across the entire industry—exchanges, brokers, regulators, tech providers—to make sure nothing breaks. One glitch at 3 a.m. ET could cascade into chaos.
The NYSE already took a similar swing at this last fall, proposing 22-hour trading for NYSE Arca (the ETF powerhouse). That application is still pending with the SEC, so Nasdaq’s move is basically saying, “Yeah, we’re doing this too.”
Cohen frames this as inevitable: “The question is not whether we can build a market that operates 24/5, but how we do so in a way that strengthens investor confidence.” Translation: This is happening. The only debate is how to make it work without breaking everything.
If approved, Nasdaq’s targeting a launch in the second half of 2026. That’s ambitious, but the momentum is real. Global capital doesn’t sleep, and the market’s finally catching up to that reality.
For retail investors, this could mean more flexibility. For institutions, it’s a competitive advantage. For the market infrastructure? That’s the real test. Let’s see if they can pull it off.
