Nasdaq Plans 23-Hour Trading Sessions

Nasdaq is seeking regulatory approval to launch nearly continuous U.S. equity trading, with a new 9 p.m. to 4 a.m. ET overnight session added to its existing extended-hours.

The proposed schedule would allow trading from 9 p.m. Sunday through 8 p.m. Friday, with only a one-hour daily processing break and all-day Saturday closed. Nasdaq says the move aims to meet growing global demand for U.S. stocks and expand access for international investors, with a targeted Dec. 6, 2026 launch, subject to approval from the U.S. Securities and Exchange Commission and Securities Information Processor readiness.

Key US Market Drivers

Geopolitical tensions are back in focus after U.S. President Donald Trump threatened to bomb Oman if it impedes efforts to end the war against Iran and re-open the Strait of Hormuz.

“If Oman gets in the way, we’ll bomb the shit out of them,” Trump reportedly told Fox News on Monday. The comments come as a two-month window to negotiate a peace deal with Iran expired on Monday, without any breakthrough.

In a separate post on Truth Social, the president reiterated, “The number one Goal is, and always will be, that Iran cannot have, in any way, shape, or form, a Nuclear Weapon.”

Global oil prices jumped higher following the remarks. Brent crude futures expiring in October were up about 0.51%, trading at $91.33 a barrel at the time of writing. Meanwhile, WTI crude futures expiring in September were trading at $85.04 per barrel, up about 0.64%.
