Remember when trading stocks meant calling your broker during business hours? Yeah, those days are long gone. Now Nasdaq is about to take things to the next level—literally around the clock.
The exchange just announced it’s filing papers with the SEC to launch 24-hour trading, five days a week. That’s right: Monday through Friday, all day, all night, no breaks. Currently, the market opens at 9:30 a.m. and closes at 4 p.m. ET, which apparently isn’t enough for the modern investor. Nasdaq President Tal Cohen says they’re aiming for a launch in the second half of 2026, pending regulatory approval and some technical coordination with the industry.
**Why Now? Global FOMO, Basically**
Here’s the thing: the world doesn’t stop trading when Wall Street closes. Investors in Tokyo, London, and Sydney have been itching to jump into U.S. markets on their own schedules. Foreign holdings of U.S. equities have nearly doubled since 2019, hitting $17 trillion as of mid-2024. That’s a lot of money sitting in different time zones, waiting for the bell to ring.
Cohen points out that 98% of the 56 new ETFs tracking the Nasdaq 100 launched in the last five years came from outside the U.S. Clearly, there’s appetite. The idea is that 24-hour trading would let international investors access American markets without setting their alarms for 2 a.m.
**But Here’s Where It Gets Messy**
Of course, nothing’s ever simple. Lower liquidity during overnight hours means wider spreads and potentially higher volatility—basically, your trades might cost more and move more wildly when the sun’s down. That’s not exactly a feature.
Corporate executives are also nervous. A Nasdaq survey found that roughly half of listed companies have reservations about expanded trading hours, particularly around liquidity and corporate actions. They’re worried about the chaos of announcements and earnings calls happening while the market’s technically open but barely anyone’s watching.
Then there’s the infrastructure nightmare. U.S. markets process millions of messages per second. Adding 24-hour trading means coordinating across the entire industry—exchanges, brokers, regulators, everyone. One hiccup and the whole system could stumble.
**The Bigger Picture**
This isn’t happening in a vacuum. The NYSE already filed to launch 22-hour trading on NYSE Arca (the ETF powerhouse) last fall. So the industry’s clearly moving toward extended hours. The question is whether the SEC will actually approve it and whether the market infrastructure can handle it without breaking.
Cohen’s confident they can pull it off. “The question is not whether we can build a market that operates 24/5,” he said, “but how we do so in a way that strengthens investor confidence.”
Translation: We can do this, but we need to do it right.
For retail investors, 24-hour trading could be a game-changer—more flexibility, more opportunities. For institutions and international players, it’s basically a no-brainer. But for the folks running the show, it’s a massive undertaking that requires everyone to play nice and keep the lights on.
Stay tuned. This one’s far from over.
