A Big Mac in Fresno, California, can cost $6.89 at one McDonald's and $5.69 at another location just two miles away, a 21% price difference driven by an AI pricing engine. The system estimates local customer "willingness to pay" to recommend optimal prices, with some recommendations in Connecticut reaching $18 for a single burger. CEO Chris Kempczinski told investors that failure to comply with these AI-recommended prices can affect franchise contract renewals, though franchisees report that corporate pressure to follow the tool has widened price gaps between neighborhoods.

McDonald's maintains the pricing portal is a tool for informed decision-making rather than a mandate and that franchisees set final costs. The company has deployed the technology across nearly 14,000 restaurants in the US and other international markets. The strategy arrives as McDonald's stock has fallen 30% since February and low-income traffic has declined by nearly double digits over two years, increasing the risk of customer backlash and antitrust scrutiny.
