Artificial intelligence now plays a role in pricing at McDonald’s. A software program is designed to help restaurants set appropriate prices for burgers and other products. It takes into account sales data and the current market situation. As a result, the price of a Big Mac can vary significantly from one restaurant to another.
Update from October 7, 2026: McDonald’s AI-driven pricing system is now also a matter for the courts. In the U.S., a consumer has filed a class-action lawsuit against the fast-food giant. The allegation: The pricing software could facilitate the exchange of competitively sensitive information between otherwise independent franchisees, potentially violating antitrust laws. According to the plaintiffs, the AI-generated price recommendations contribute to aligning the pricing of individual restaurants. McDonald’s denies the allegations, emphasizing that the suggested prices are non-binding.
Back to the original report:
Big Mac costs 21 percent more
As reported by the news agency “Reuters,” McDonald’s uses the system in the U.S. and other markets. In the United States, the platform processes millions of sales data daily from nearly 14,000 restaurants. It also shows what prices competitors in the area, such as Burger King and Wendy’s, are charging.
The differences between individual McDonald’s restaurants can be significant, as shown by an example from Fresno, California. In a company-owned restaurant, a Big Mac cost $5.69, while another location charged $6.89.
These two restaurants are only about two miles apart, yet the Big Mac costs 21 percent more at one of them. However, Reuters could not confirm whether AI is responsible for this difference. The system has also recently recommended lower prices.

Operators report pressure from McDonald’s
The final decision on product pricing still lies with the restaurant operators. However, several of them report pressure from McDonald’s. Five operators told Reuters that the company insists on using the AI tools. McDonald’s notes when requested prices deviate from the system’s recommendations.
Former operators also report attempts at influence. They describe calls from the corporate headquarters after they set prices that did not match the suggested amounts.

McDonald’s disputes this portrayal. According to the company, operators can still decide for themselves what prices to charge. Additionally, costs and market conditions can vary even between restaurants that are only a few miles apart.
McDonald’s points out legal risks
The shared pricing platform is apparently not without complications. McDonald’s itself highlights potential legal risks in its pricing portal. Franchisees operate their restaurants as independent entrepreneurs. Although they work under the same brand, they can compete for the same customers.
Accordingly, operators must comply with antitrust laws, which include regulations to prevent illegal price-fixing. However, McDonald’s emphasizes that this warning alone is not evidence of anti-competitive behavior.
