Catenaa, Tuesday, December 16, 2025- Nasdaq, the second-largest exchange in the US, is seeking regulatory approval to extend trading hours on its stock venues to 23 hours during the workweek.
The firm requested permission from the Securities and Exchange Commission to add a trading session, from 9 p.m. to 4 a.m. ET, according to a filing Monday.
That would be on top of the pre-market, regular, and post-market hours the firm already operates, the firm said.
“This evolution reflects a simple reality: global investors expect access on their terms, in their time zones, without compromising trust or market integrity,” Chuck Mack, senior vice president of North American markets at Nasdaq, said in an emailed statement.
Market participants outside the US trading welcomed the potential for faster pricing on earnings and macroeconomic developments, though they cautioned that near-continuous trading would give investors less time to digest after-hours headlines and may lead to more extreme swings during hours when liquidity is thin.
Earlier this year, Nasdaq announced its intention to offer additional trading hours on its equities exchange, seeking to capitalize on growing global demand for US stocks.
It expects to be ready for extended trading early in the third quarter of 2026, pending regulatory approval and alignment with the rest of the industry.
Other exchanges have also outlined their own path to extending trading hours on their venues, including the New York Stock Exchange, which plans to offer trading 22 hours on weekdays.
That proposal got initial approval from the SEC in February, pending updates to the market’s data feed.
Extended trading hours became more common during the pandemic, allowing investors to react to market-moving events immediately.
Firms such as Robinhood Markets and Interactive Brokers Group started enabling customers to buy and sell US stocks 24 hours a day, five days a week, on off-exchange venues like Blue Ocean’s alternative-trading system.
