Yes. As of Labor Day morning, Sept. 7, 2026, Brown University’s Iran War Energy Cost Tracker estimated that higher U.S. gasoline and diesel prices since the war began on Feb. 28 have cost consumers about $100 billion—more than $760 per household on average.
Axios reported the milestone from the Watson School tracker, which compares actual AAA fuel prices with a modeled no-war price path and multiplies the gap by consumption. The running total is still rising, and Texas has borne the largest state share so far (about $11 billion), followed by California and Florida.
