McDonald's is facing a lawsuit alleging the use of machine-learning algorithms to illegally fix menu prices. Reuters reported that the company's pricing engine analyzes data from millions of daily transactions across nearly 14,000 restaurants. The lawsuit, filed in Chicago, claims McDonald's violated US antitrust law by conspiring with independent franchisees to fix prices using algorithms trained on nonpublic data.

MCD closed at $231.89 on October 2, 2026, with the stock reaching a day high of $233 and a low of $230.83. McDonald's said in a statement that the allegations are speculative and uninformed, asserting that AI does not directly set menu prices, while the lawsuit alleges the company leverages its franchised system to increase costs for consumers.
