Key points

  • Plaintiffs allege McDonald’s and franchisees colluded on pricing via AI since 2019.
  • The suit claims algorithms set prices based on local purchasing behavior and willingness to pay.
  • McDonald’s denies allegations, stating franchisees set their own prices and AI only recommends them.

McDonald’s faces an antitrust class-action lawsuit alleging that the company coordinated pricing with its franchisees using artificial intelligence algorithms. The suit claims this practice effectively colluded on prices, potentially inflating costs for consumers across the United States since 2019.

The proposed legal action argues that instead of competing on affordability, McDonald’s and its independent restaurant operators used AI-driven recommendations to set uniform prices. According to Reuters, the algorithm considers local purchasing behavior and estimates of what consumers in specific locations are willing to pay for individual menu items.

Pricing Mechanism and Allegations

The lawsuit contends that this coordination violates antitrust laws by preventing independent businesses from setting their own prices. Lark Turner, a lawyer representing the plaintiffs, stated that McDonald’s is leveraging its data troves and franchised system to nickel-and-dime consumers down to the last French fry.

Reuters reports that the AI system sets prices at roughly 14,000 restaurants in the US. The algorithm suggests prices for individual menu items based on various data factors. The suit argues this results in unlawful price coordination that harms consumers by removing competitive pricing pressures between franchise locations.

Corporate Response and Industry Context

McDonald’s has disputed the claims, asserting that AI does not set the price of a Big Mac or any other menu item. The company stated that franchisees retain the authority to decide their own menu item prices. McDonald’s added that using AI to recommend prices is a common practice across multiple industries.

The fast-food chain noted that dynamic pricing is not unique to its operations. Other major firms, including Sony, Amazon, Walmart, and Best Buy, also adjust prices multiple times throughout the day. This means consumers may pay different amounts for the same item depending on the time of day they shop.

What should you do?

The lawsuit is in its early stages and seeks damages on behalf of potentially millions of consumers. If you believe you were affected by these pricing practices, you may be eligible to join the class action. Monitor legal updates for filing deadlines and eligibility requirements related to this specific antitrust case.

What to do and how to stay safe: McDonald's

  • Review past receipts from McDonald’s locations to document price variations for potential evidence if joining the suit.
  • Monitor official court filings or legal notices for deadlines to opt out of the class-action settlement.
  • Compare prices across different franchise locations in your area to identify potential uniform pricing patterns.
  • Consult with a legal professional to understand your rights and eligibility for damages under this specific antitrust claim.
