McDonald's faces a proposed nationwide class-action lawsuit filed in Illinois alleging that its AI-powered pricing system violates federal antitrust laws. The plaintiff argues that the centralized tool, which analyzes nonpublic sales data and competitor prices to generate recommendations for franchisees, effectively coordinates menu pricing across independently operated locations, potentially fixing prices and harming consumers. McDonald's strongly denies these allegations, stating that its technology provides only recommendations rather than setting mandatory prices or changing them in real-time. The company asserts that franchisees retain full autonomy over final pricing decisions based on local market dynamics, distinguishing their approach from dynamic or personalized pricing models that adjust to individual customers or time of day. The legal challenge arises amidst broader scrutiny of AI-assisted pricing tools in the restaurant industry, which use data to help operators manage rising costs and optimize value. While McDonald's maintains its system helps franchisees deliver value without mandating specific prices, the lawsuit claims the shared data infrastructure reduces competition among franchises, potentially leading to higher menu prices for diners as operating expenses continue to climb.
