President Donald Trump’s claims about gas prices weren’t true when he made them during his State of the Union address last week. Now those claims are aging like milk.

The fallout from his strikes on Iran over the weekend appears to have disrupted the global energy market ― and Americans are already paying for it at the gas pump, trackers show.

Fuel market expert Patrick De Haan, who runs the gas price tracker Gas Buddy and posts real-time fuel cost updates on social media, noted that gas prices began “ramping up” on Monday and surpassed a national average of $3 a gallon. That’s the first time since December that the national average has been that high, he said on X.

On Tuesday, he observed, gas prices saw their biggest single-day rise since Russia invaded Ukraine in 2022. Following that rise, he predicted average prices would reach up to $3.35 a gallon if trends hold steady.

A survey by AAA found similar prices at gas pumps this week.
