McDonald’s Faces Lawsuit Over AI-Driven Menu Pricing
McDonald’s is facing a proposed class-action lawsuit alleging that its artificial intelligence-powered pricing tools enable illegal price-fixing among independently owned restaurants, potentially driving up the cost of fast food for American consumers. The lawsuit was filed on October 2, 2026, in federal court in Illinois and challenges how the company gathers and uses pricing and sales information across its US franchise network.
The complaint was brought by Michael Thomas, an Illinois consumer who says he regularly purchases McDonald’s food and noticed price differences among restaurants near his home. His lawsuit argues that the company’s pricing system undermines competition by allowing franchise locations to share nonpublic business information through a centralized platform.
At the center of the case is a pricing tool that uses artificial intelligence and business data to help franchisees determine menu prices. According to the complaint, the system analyzes information from transactions across thousands of restaurants, including store-level sales and pricing data that competing businesses would not ordinarily exchange directly.
The plaintiff alleges that sharing this information through a common platform can make it easier for competing restaurants to align their pricing decisions rather than independently setting prices based on their own business needs. The lawsuit characterizes the alleged arrangement as algorithmic price-fixing and claims that consumers ultimately pay more as a result. These allegations have not been proven in court.
McDonald’s operates a franchise-heavy business model in the United States. Approximately 95% of its roughly 14,000 US restaurants are independently owned and operated by franchisees. Under the company’s stated policy, those operators make their own menu-pricing decisions, although the lawsuit alleges that corporate recommendations and business relationships give McDonald’s significant influence over their choices.
The complaint also alleges that franchisees face pressure to follow the pricing tool’s recommendations. It claims that McDonald’s monitors deviations from the system and that franchise owners may face consequences if they do not comply. The allegations raise questions about whether the pricing recommendations are genuinely optional or function as a mechanism for coordinating prices across otherwise competing businesses.
The dispute comes amid sustained public scrutiny of rising fast-food prices. McDonald’s has previously reported that the average price of its menu items increased by approximately 40% between 2019 and 2024. The lawsuit argues that the company’s pricing practices contributed to the burden on customers, although the increase alone does not establish that the AI tool caused higher prices or violated antitrust law.
McDonald’s has rejected the allegations, calling the complaint inaccurate and saying it intends to defend itself vigorously. The company maintains that artificial intelligence does not set menu prices directly and that franchisees retain control over their individual restaurant prices. It describes the technology as an optional decision-support tool intended to help operators evaluate sales, location and competitor pricing.
The company has also disputed claims that it uses dynamic pricing to automatically change menu prices. Its position is that providing information and recommendations to franchisees is different from coordinating prices or requiring restaurants to charge the same amounts. The court will need to assess the actual operation of the system and the evidence supporting the competing descriptions.
The lawsuit seeks class-action status, which could allow other eligible consumers to join the case. It requests financial damages and a court order preventing McDonald’s from enforcing arrangements that allegedly restrict competition. The proposed class has not yet been certified, and the requested remedies have not been granted.
The case raises a wider legal question about how existing antitrust rules apply to algorithmic pricing. Businesses increasingly use software to analyze market conditions and recommend prices, but regulators and courts must distinguish legitimate business analytics from systems that may facilitate unlawful coordination among competitors. The use of an AI tool by itself does not prove price-fixing; the central issue is how the tool operates and whether it undermines independent pricing decisions.
The outcome could have implications for other franchise businesses that use centralized pricing systems and shared commercial data. If the plaintiff establishes that the platform unlawfully coordinated pricing, the case could lead to financial liability or restrictions on how the company provides pricing recommendations. If McDonald’s successfully defends its practices, the dispute may instead reinforce the distinction between offering analytical guidance and illegally coordinating prices. For now, the allegations remain unresolved.
