McDonald’s is facing a proposed nationwide class-action lawsuit accusing the fast-food giant of using an artificial-intelligence-powered pricing system to coordinate menu prices across independently owned franchises and company-operated restaurants. Filed in federal court in Chicago by Illinois customer Michael Thomas, the complaint alleges that since at least 2019 McDonald’s has pooled nonpublic sales information and used machine-learning algorithms to generate pricing recommendations, undermining the independent price competition that should exist among franchisees. The lawsuit contends the arrangement violates federal antitrust law and caused consumers to pay artificially inflated prices. McDonald’s rejects the allegations as speculative, maintaining that its technology merely provides recommendations and that franchise owners retain authority over what customers ultimately pay. The case could become an important test of whether centralized AI pricing systems cross the legal line from legitimate business analytics into algorithmically facilitated price coordination.
Key Takeaways
- The proposed nationwide class action alleges McDonald’s used a centralized machine-learning pricing engine and confidential restaurant data to coordinate prices among businesses that are supposed to make independent pricing decisions.
- The complaint alleges the pricing system has operated since at least 2019, with additional reporting indicating McDonald’s analyzes millions of transactions across nearly 14,000 U.S. restaurants to produce restaurant-specific pricing recommendations.
- McDonald’s strongly denies that AI actually sets menu prices or that it practices dynamic pricing, insisting franchisees retain final pricing authority; the central legal question is whether recommendations backed by pooled proprietary data and corporate influence nevertheless amount to unlawful coordination.
In-Depth
The lawsuit against McDonald’s raises a question likely to become increasingly important as artificial intelligence spreads throughout corporate America: When does sophisticated pricing advice become price coordination?
The proposed nationwide class action, filed in the Northern District of Illinois, alleges McDonald’s has operated a centralized machine-learning pricing engine since at least 2019. According to the complaint, confidential sales information from franchisees and company-owned restaurants is pooled and analyzed to generate recommended menu prices. The plaintiff argues that this effectively coordinates businesses that should independently determine what customers pay.
That distinction matters. Using technology to analyze costs, demand and competitors is hardly unusual, nor is there anything inherently unlawful about AI-assisted business decisions. But antitrust concerns become more serious if supposedly independent competitors feed proprietary information into a common system that then guides their prices in the same direction. The lawsuit also alleges McDonald’s exerted pressure on franchisees to follow its recommendations, potentially weakening the company’s argument that the system is merely advisory.
McDonald’s categorically disputes that characterization. The company says AI neither sets nor changes menu prices, denies using dynamic pricing and maintains that individual franchisees make the final decisions.
The case therefore should not be reduced to the simplistic proposition that “AI fixed Big Mac prices.” These remain allegations requiring proof. But the lawsuit presents a legitimate question for courts and regulators: If competitors cannot lawfully coordinate prices directly, corporations should not be permitted to accomplish the same result indirectly through centralized algorithms. Technological sophistication cannot become a loophole around longstanding competition law.
