Key Highlights
- The SEC approved extended-hours proposals from Nasdaq and NYSE Arca for U.S. equities.
- Nasdaq plans trading from 4 a.m. to 8 p.m. ET, followed by a separate overnight session.
- NYSE Arca targets December 6, 2026 for its extended-hours trading launch.
U.S. stock exchanges are moving toward a trading day that looks a lot more like crypto’s. The SEC has already approved proposals from Nasdaq and NYSE Arca to extend equities trading to roughly 22 to 23 hours a day, five days a week, with 24X Exchange holding similar approval as a newer entrant built for extended-hours trading from the start.
In a blog post this week, Binance pointed to its tokenized U.S. stock product, bStocks, as an example of the demand that already exists outside traditional U.S. market hours.
What’s approved, what’s still pending
None of the extended-hours plans currently on the table amount to true, gapless 24/7 trading. Nasdaq’s approved structure splits the day into a 4:00 a.m.–8:00 p.m. ET “Day Session” and a 9:00 p.m.–4:00 a.m. “Night Session,” with a one-hour pause between them reserved for system maintenance and processing corporate actions. NYSE Arca’s approved schedule runs 1:30 a.m. to 11:30 p.m. ET Monday through Thursday and 1:30 a.m. to 8:00 p.m. on Fridays, with a targeted launch of December 6, 2026. Both plans, like 24X’s, stop for the weekend.
A separate piece of infrastructure is still working through the SEC’s review process: the Securities Information Processors, which operate the consolidated data feeds that broker-dealers and trading systems rely on, have proposed extending their own operating hours to nearly cover the full week, an amendment the SEC has up to 300 days to act on. Until that’s approved, extended-hours trading can outpace the market data infrastructure meant to support it.
Binance’s case: the liquidity question, not just the clock
Binance’s blog post argues that simply extending trading hours doesn’t by itself solve the harder problem — having enough global liquidity to actually fill those overnight hours.
The company points to its own bStocks product as evidence of what that liquidity pattern looks like in practice: on-chain activity on bStocks peaks as the Asian trading day begins, and Binance said 92% of bStocks’ on-chain volume in the week to July 28 occurred while U.S. markets were closed.
More broadly, the company said 44% to 47% of bStocks volume already happens outside standard U.S. market hours, and that more than 90% of Binance’s overall user base comes from emerging markets, according to Binance Research.
Complementary, not competitive
Binance frames the broader shift as convergence rather than a zero-sum contest between crypto platforms and traditional exchanges.
The company’s argument is that traditional finance is adopting the always-on market structure crypto built first, while crypto platforms supply the global, cross-time-zone user base needed to keep that structure liquid around the clock.
Binance describes this as incremental liquidity — new users, new geographies and new trading hours added to U.S. assets — rather than volume pulled away from existing exchanges.
What this means
Traditional exchanges now have regulatory approval to run trading days nearly three times longer than before, with NYSE Arca’s December 6 target date the most concrete on the calendar so far.
Whether those extended hours actually attract meaningful trading volume, or simply extend the window without much activity in it, is the open question Binance’s post is positioned to answer with its own data — figures that, as with any company reporting on its own product’s usage, come from Binance itself rather than an independent source.
