McDonald's is currently facing a nationwide class-action lawsuit in a Chicago federal court, with accusations that the fast-food giant is utilizing an AI-driven system to artificially inflate menu prices. The plaintiff argues that the company is violating antitrust laws by conspiring with its independent franchisees to coordinate pricing across both corporate and franchised locations. By leveraging proprietary, nonpublic data, the suit claims the restaurant chain is undermining the independence of its franchise owners to keep costs consistently high for consumers.

In response to the legal action, McDonald’s has firmly denied the allegations, labeling them as speculative and inaccurate. The company maintains that its AI tools are merely used for analytics and recommendations, emphasizing that individual franchisees retain full authority over setting their own menu prices. While this case mirrors a growing trend of litigation targeting companies that use algorithms to manage pricing, McDonald's insists its practices are standard in the industry and do not constitute illegal collusion.
