Gas Prices Spike in Every State

(Undated) — It’s the “spike no one wanted.” According to GasBuddy Head of Petroleum Analysis, Patrick De Haan, gas prices rose in every state over the last week, with some of the most significant and fastest increases concentrated in the Great Lakes, where states like Michigan, Indiana, Ohio, and Illinois saw sharp spikes, while Wisconsin experienced more modest gains. He says at the same time, diesel prices surged to new records in parts of the region, with some areas touching the $6-per-gallon mark. De Haan says while refinery outages were a key driver behind those outsized increases, early signs of improvement could help ease some of the most extreme price pressures. Beyond the region, markets are also digesting a wave of new developments, including OPEC+ raising production for June and President Trump outlining a plan to free stranded ships, which could help restore some supply. However, De Haan says, “with so many moving pieces, the outlook remains highly fluid.” The current national average for a gallon of regular unleaded is $4.49.
