Warren and four other lawmakers question McDonald's over algorithmic pricing

what happened

Senator Elizabeth Warren and four other Democratic lawmakers have sent a letter to McDonald's CEO Chris Kempczinski asking about the chain's algorithmic pricing. The letter, dated November 2, was shared with Reuters, which says it builds on its September 29 investigation into machine-learning tools that suggest a best price for every item at each location, partly based on what local customers are estimated to be willing to pay.

The lawmakers want to know whether the tools use data from individual loyalty-program members, how franchisees are encouraged to adopt them, and what antitrust review took place before launch. They asked for answers by November 16. McDonald's has not replied to Reuters' request for comment on the letter. Earlier, the company said its tools do not rely on individual customer data, that franchisees set their own prices, and that the recommendations are optional.

Separately, two consumer class actions in federal court accuse the company of using the system to coordinate menu prices illegally across franchised and company-owned locations.

why it matters

For the stock, the letter alone is unlikely to be a major driver. A bigger question for investors is whether regulators or courts move against algorithmic pricing, since that could affect how the chain sets prices across its network.
