California Lawsuit Alleges AI-Powered Gas Price Fixing by Major Stations
A proposed class-action lawsuit filed in Sacramento federal court accuses major gas station operators—including BP, Walmart, 7-Eleven, Circle K, and Marathon Petroleum—of using an AI pricing tool from Kalibrate to illegally coordinate and inflate gasoline prices in California. The suit claims the algorithm shares data among competitors, raising prices up to 30 cents per gallon and costing drivers millions annually. It cites California’s high average gas price ($5.58/gallon) and seeks damages under state antitrust law and Assembly Bill 325, which targets algorithmic price fixing.
