California drivers are suing BP, Walmart and Marathon for using an AI tool to fix gas prices

California drivers filed a class-action lawsuit against BP, Marathon, 7-Eleven, Walmart and Albertsons, alleging their shared use of Kalibrate Fuel Systems' AI pricing platform inflated gas prices by up to 22 cents a gallon. The case is one of the first filed under California's new AB 325 law banning shared pricing algorithms, and its outcome could determine whether AI vendors share antitrust liability alongside the operators who use their tools.
