. This represents a significant shift in how the fast-food industry approaches pricing strategy, with transaction data now driving decisions that were once based primarily on regional cost structures.

The pricing system evaluates multiple factors, including customer willingness to pay in specific areas. Screenshots of the franchisee interface reviewed by Reuters show messages like "Your restaurant is showing MEDIUM SENSITIVITY to Price" based partly on local customer behavior2

. The platform also pulls public price information from online menus of competitors including Wendy's and Burger King, though those chains confirmed they do not use AI in pricing decisions2

Stark Price Variations Emerge Across Neighboring Locations

The implementation of McDonald's AI to dynamically price its burgers has created notable price variations between nearby stores1

1

. A Reuters investigation found that a company-run store in Fresno, California sells a Big Mac for $5.69, while another company-run restaurant just two miles away charges $6.89 for the same sandwich—a 21% premium2

. Three franchisees confirmed to Reuters that the engine has widened existing price differences for identical products between restaurants, including from neighborhood to neighborhood within the same area2

.

These price variations reflect the system's core function: determining optimal menu prices by assessing what customers in each specific location will pay. McDonald's defended this approach, stating that costs and other factors vary across stores, and restaurants even a few miles apart can belong to distinct markets2

. The company has been using some version of this technology since at least 2019, but CEO Chris Kempczinski boasted to investors in 2023 that the company had developed proprietary tools to evaluate pricing at individual restaurants1

Store owners described receiving phone calls from corporate after straying from pricing recommendations. Former store owner Karen King stated, "You don't really have much of a choice anymore"1

. CEO Kempczinski recently told investors that "pricing non-compliance in certain cases is part of those conversations" regarding contract renewals1

. This leverage is significant, as McDonald's corporate holds power over whether franchisees can renew their licenses or open new locations1

Antitrust Concerns and Legal Risks Surface

The company acknowledges that using dynamic pricing systems could expose franchisees to legal hurdles. The pricing portal's terms of service warn that users "may be competitors of each other" and emphasize the importance of understanding and complying with antitrust and competition laws1

Industry Backlash and Competitive Implications

Brooklyn resident Diane Bezucha captured consumer sentiment: "It's in the interest of the company to know where there's demand and to get that feedback in real time," but if technology raises prices simply due to demand, "that doesn't really help me as a customer"2
