McDonald's sued in proposed class action alleging its AI-powered pricing system was used to fix menu prices
McDonald's was sued in federal court in Chicago in a proposed nationwide class action. The suit alleges the company violated U.S. antitrust law by conspiring with independent franchisees to coordinate menu prices using an AI-powered pricing system with algorithms trained on nonpublic data. The plaintiff, an Illinois resident, seeks to represent potentially millions of McDonald's customers. McDonald's called the allegations speculative and uninformed, saying AI does not set menu prices and franchisees make their own pricing decisions.
