If your usual McDonald’s order seems more expensive than it used to, a new lawsuit is raising questions about how the chain recommends prices to its restaurants. In October 2026, McDonald’s faced legal challenges alleging that its AI-assisted pricing system may help coordinate prices across competing locations. The complaints argue that the technology could undermine competition and contribute to higher menu prices. McDonald’s strongly disputes those claims, saying its software does not set prices and franchisees remain responsible for their own decisions. The cases are still in their early stages, so customers should understand what is actually being alleged before assuming the company uses AI to charge them more.
What Is McDonald’s AI Pricing Tool?
McDonald’s uses a technology-assisted pricing system designed to help restaurant operators make decisions about menu prices. According to reporting on the lawsuit, the system uses machine-learning technology to analyze information from many transactions across the chain’s U.S. restaurants. Factors described in reporting include restaurant-level sales, location, and competitors’ prices. The system then generates pricing recommendations intended to help operators assess what they should charge for menu items.
McDonald’s says the tool provides information rather than automatically changing prices. The company states it does not use AI to determine how much an individual customer is willing to pay, and it denies using dynamic pricing that changes menu prices in real time. The distinction matters because pricing recommendations and automated price changes are different practices. The central legal question is whether the information used to make those recommendations could improperly influence pricing decisions among restaurants that are supposed to compete with one another.
How Does the System Work?
The system reportedly analyzes restaurant sales and other market information to help identify prices that could work for individual locations. For example, a restaurant in a busy commercial district may face different costs and customer demand than one in a smaller town. Comparing local conditions can help an operator decide whether a particular menu item is priced appropriately. Businesses commonly use sales data, market research, and software to inform these decisions.
However, the lawsuit raises a different concern about how the data are collected and used. Many McDonald’s locations are independently owned franchises, meaning they operate under the same brand while making certain business decisions themselves. The complaint alleges that sharing nonpublic sales and pricing information through a common system could allow competing restaurants to coordinate prices indirectly. The plaintiff also points to alleged pressure on franchisees to engage with the company’s pricing recommendations. McDonald’s maintains that the tool is optional and does not coordinate or fix prices.
What Is the Lawsuit Actually Alleging?
The first proposed class-action lawsuit was filed on October 2, 2026, in the U.S. District Court for the Northern District of Illinois. The plaintiff, Michael Thomas, is an Illinois McDonald’s customer who says he noticed different prices at nearby locations. His complaint alleges that McDonald’s uses its pricing platform to facilitate unlawful price coordination among restaurants that should be setting prices independently. It also argues that the system contributed to higher prices for consumers.
A second related proposed class action was filed on October 15, 2026, raising similar concerns and naming Deloitte Consulting LLP as an additional defendant. The complaints seek to represent groups of customers who purchased McDonald’s food and request legal remedies that include damages and restrictions on the alleged practices. These are allegations, not findings by a court. Neither the filing of a lawsuit nor the existence of a pricing algorithm proves that illegal price-fixing occurred, and the proposed classes have not been certified.
Why Is Sharing Pricing Data a Potential Problem?
The legal issue centers on competition. Businesses generally must make independent pricing decisions rather than agree with competitors to keep prices at a particular level or coordinate increases. If competing restaurants share sensitive information through a system that encourages them to follow similar recommendations, that arrangement can raise antitrust questions. The concern is that competitors could end up making pricing decisions based on one another’s behavior rather than competing independently for customers.
The complaint also draws attention to reporting about a pricing recommendation mechanism that allegedly considers how many restaurants have already raised prices on a particular item. One reported allegation describes a threshold involving restaurants representing at least 30% of locations. The plaintiff argues that using this type of information could encourage additional restaurants to follow price increases. That description comes from allegations and reporting cited in the litigation, not a court finding that the system operates illegally. Whether the actual process violates antitrust law will depend on the evidence and legal arguments.
What Has McDonald’s Said in Response?
McDonald’s has rejected the claims, describing the lawsuit as inaccurate and saying it intends to defend itself. The company maintains that AI does not set menu prices and that franchisees independently determine what customers pay at their restaurants. It also argues that using analytics to understand local costs, demand, and competition is a normal business practice. Under its explanation, the tool supplies context for operators rather than automatically setting or coordinating prices.
That response is important because franchisees account for approximately 95% of McDonald’s roughly 14,000 U.S. restaurants. The company says franchisees are not required to accept its pricing recommendations. However, the plaintiff alleges that McDonald’s has significant influence over franchise operators and can pressure them to follow its guidance. The court will need to consider the evidence behind these competing positions. Until then, it would be inaccurate to describe the allegations as proven price-fixing or to say that a court has ordered McDonald’s to change its pricing system.
Could the Lawsuit Change What You Pay?
For now, customers should not expect an immediate price change simply because the lawsuits were filed. The cases are at an early stage, and there has been no final ruling establishing that McDonald’s violated antitrust law. A lawsuit can take considerable time to move through the court system, and the outcome could depend on evidence that has not yet been tested publicly. Any eventual changes to pricing practices would also depend on the terms of a settlement or court decision, if one occurs.
The case could still matter to customers over time. If the allegations are substantiated and the court orders changes, McDonald’s could face limits on how its pricing recommendations are developed or used. That would not automatically guarantee lower prices, because individual restaurants still face local operating costs and make decisions about their menus. For now, the lawsuit is primarily about how prices may be influenced, not a promise that customers will receive refunds or see cheaper meals.
What Can Customers Do About Rising McDonald’s Prices?
Customers do not need to wait for the lawsuit to make more informed choices. Menu prices can vary by location, so checking the total at your usual restaurant and comparing it with another nearby location may reveal differences. McDonald’s app promotions and value offers can also reduce the cost of a regular order, although availability and terms vary. Compare the final price after any required purchases, rather than assuming every advertised deal saves money.
It is also worth distinguishing between a higher menu price and personalized pricing. McDonald’s says its tool does not calculate prices based on an individual customer’s willingness to pay or change them in real time. The lawsuit challenges how restaurant pricing recommendations may be coordinated, not a proven system that charges different customers different amounts for the same order. As the cases develop, the most important questions will be whether the system undermines independent pricing decisions and what evidence supports the claims.
What Happens Next Could Matter for Fast-Food Customers
The McDonald’s lawsuit raises a bigger question about how much influence pricing technology should have over what customers pay. While the allegations have not been proven, the case could help clarify where businesses can draw the line between using data to make pricing decisions and potentially limiting competition. For now, customers shouldn’t assume the tool automatically raises their prices or that a court will force McDonald’s to lower them. The most important development to watch is whether the plaintiffs can show that the system undermines independent pricing decisions among franchisees. Until then, comparing local menu prices and checking app offers remain practical ways to keep your next order affordable.
