Five US lawmakers sent a letter to McDonald's CEO Chris Kempczinski questioning the company's use of machine learning pricing algorithms, and two consumer class action lawsuits in federal court allege the system coordinates menu prices across franchised and company-owned restaurants. McDonald's has not responded to a request for comment on the letter, and the matter is at the stage of congressional inquiry and litigation rather than any regulatory finding.
Why it matters
The letter and lawsuits put algorithmic price-setting under scrutiny in a large consumer retail chain, raising the question of whether shared software can make nominally independent franchisees act like competitors who coordinate prices. The lawmakers' questions, including whether loyalty-program data feeds the tools and what antitrust review preceded deployment, point to where regulators may press next.
The evidence consists of a congressional letter citing a Reuters report plus two federal class action filings, with five lawmakers signing and three franchisees describing wider local price gaps. The letter asks whether the tools use individual loyalty-program data and what antitrust review preceded their deployment, but no figures on the size of price differences were published, and the answers remain unknown.
The players
McDonald's Corporation
The global fast-food chain, whose franchise-and-company-owned model and centralized pricing engine are at the center of the letter and lawsuits.
Chris Kempczinski
The chief executive of McDonald's, to whom the lawmakers addressed their letter questioning the company's algorithmic pricing.
Elizabeth Warren
The Massachusetts Democratic senator, whose home state is noted in the reporting, and who is among the lawmakers raising concerns about AI-driven pricing.
The details
McDonald's uses machine learning algorithms to generate what it calls 'optimal price' recommendations for each menu item at each restaurant. Those recommendations are based partly on an estimate of how much each store's typical patrons are willing to pay, which is the mechanism the lawmakers and plaintiffs are focused on. The lawsuits argue that a single centralized system is used to coordinate prices across franchised and company-owned locations, which would make the recommendations more than independent local decisions. McDonald's says franchisees are free to set their own prices.
Timeline
September 29: Reuters reported that McDonald's uses machine learning pricing algorithms.
November 2: Five lawmakers dated their letter to McDonald's CEO Chris Kempczinski.
November 3: Reuters reported on the lawmakers' letter.
November 16: Lawmakers requested McDonald's response by this date.
The Tech Race
The McDonald's allegations extend a legal theory already tested against shared rent-pricing software into the fast-food sector, where franchisees are formally independent. The outcome will indicate whether the coordination argument carries over from housing markets to consumer retail.
If the algorithmic pricing allegations hold, customers at nearby McDonald's locations could see menu prices diverge or move together in ways not set by local franchisees. No changes to prices or to the pricing tools have been announced, and any effect on shoppers remains unconfirmed.
The takeaway
Watch whether McDonald's answers the lawmakers by November 16 and whether it addresses the loyalty-data and antitrust-review questions directly. Track the two federal class actions for any ruling on whether a shared pricing engine can be treated as coordination among franchisees.
What happens next
McDonald's response to the lawmakers' letter is requested by November 16, the date the letter sets for a reply.
