US futures rip higher as Iran weighs ending the war

US stock futures are racing higher after word that Iran's security chief met with the Supreme Leader to discuss ending the war. S&P 500 futures climbed 0.40%, according to the market account @BullTheoryio, which flagged the surge. Nasdaq futures moved even harder, up 0.60%.

The trigger, per the account, is a sit-down between Iran's top security official and the country's Supreme Leader aimed at winding the conflict down. That claim has not been independently confirmed. The headlines landed while regular trading hours were still closed, leaving futures to do the talking.

The size of the pop is the real attention-grabber. @BullTheoryio estimated that if the move had happened during regular trading hours, $350 billion would have been added to the US stock market in just 25 minutes. It's a back-of-the-envelope figure, not cash changing hands, but it captures how violently one headline can move the tape.

Futures are where geopolitical news gets priced first, and overnight sessions can swing hard on a single report before the cash market ever opens. Friday's close is old news the second something like this crosses the wire.

Now the question is whether the gains stick. Traders will be watching for confirmation of the meeting, and for whether the bid holds once Wall Street's regular session gets going. For now, the numbers on the screen are green and moving.

A war ending — or even the hint of one — is the kind of thing that reshapes the mood across markets in a hurry. Whether this one is real or just a headline, the overnight reaction already happened.
