McDonald’s Faces Lawsuit Over Alleged AI Menu Price Coordination
A customer has sued McDonald’s over how prices are decided.
The lawsuit says the company used computer algorithms and information from its restaurants to help coordinate prices.
It argues this may break laws that protect fair competition.
The case was filed in a federal court in Chicago.
The customer wants the case to include potentially millions of McDonald’s customers around the country.
McDonald’s says the claims are speculative and uninformed.
The company says its AI does not set menu prices and that franchisees choose their own prices.
The court case will address whether the pricing practices broke the law.
A proposed nationwide class action accuses McDonald’s of coordinating prices through an AI-powered pricing system.
The lawsuit was filed in federal court in Chicago on Friday and alleges violations of U.S. antitrust law.
It cites a report describing machine-learning analysis of transactions across nearly 14,000 restaurants.
McDonald’s says AI does not set menu prices and franchisees independently determine their prices.
