McDonald’s is being sued for using an AI pricing engine that allegedly coordinates franchise prices
“The algorithm that prices your fries may have been talking to every other McDonald’s in America.”
The Story
A proposed nationwide class action filed in Chicago alleges McDonald’s used a machine-learning pricing engine trained on pooled, nonpublic sales data from thousands of independently owned franchises and company stores to generate “optimal” prices, amounting to algorithmic price-fixing. McDonald’s says AI does not set prices, franchisees do, and the tools are optional recommendations. The suit cites a Reuters investigation into the system and claims it helped drive large price increases.
Why It Matters
The most American food object—the Big Mac—now has an invisible co-conspirator that may have turned competing franchisees into a single algorithm. Concrete lawsuit + money + institutions; the weirdness is that “recommended” prices can look like a cartel when the data is shared.
Evidence
Reuters, Bloomberg Law, Newsweek, the Chicago federal complaint.
