McDonald's is facing a federal lawsuit accusing the chain of using artificial-intelligence-powered menu technology to coordinate prices across thousands of U.S. restaurants in violation of antitrust law, according to USA Today.

The complaint targets the personalization software that selects what appears on McDonald's drive-thru and kiosk screens based on order time, weather, basket contents and other signals. Rather than functioning as a marketing layer, the plaintiffs argue, the system acts as a uniform pricing mechanism applied across restaurants that no competitor can undercut.

How the technology works

Menu boards at U.S. chains have shifted from printed vinyl to screens that re-price items by minute. The underlying software pushes a longer-distance drive when a guest orders only an entrée, swaps a breakfast item into the suggested bucket during the morning window, or elevates a larger fry order on hot afternoons. Chains that have deployed such systems cite check-average lifts of roughly $0.50 to $1 per transaction alongside throughput gains of several seconds per car.

The deployment replaces printed menu boards, static POP and human-managed pricing calendars, and the bill is split between corporate license fees and franchisee implementation costs.

What does the lawsuit claim?

According to USA Today, the plaintiffs' core theory is that algorithmic coordination does not require a phone call or an email chain. Identical software running at every location, set by the same corporate entity, can converge on identical menu prices and item mixes across an entire market. Once those prices reach the screen, the algorithm — not the franchisee or local operator — has made the call.

For a system dominated by franchised restaurants, the complaint frames the technology as a corporate override of the pricing independence operators have historically retained.

Where regulators have landed

The Department of Justice and Federal Trade Commission have flagged the broader category. In 2023 joint guidance on evaluating person-level pricing tools and common algorithms, the agencies warned that competing firms using shared pricing software can converge on identical outputs without explicit collusion — and still run afoul of the Sherman Act. Restaurants, hotels and airlines were not carved out.

The case is the first major U.S. restaurant-industry complaint to bring that theory to menu-board software.

What operators should check now

Outside counsel watching the docket expect the case to turn on three pieces of evidence. Chains running menu optimization should expect plaintiffs' counsel and regulators to press for: (1) documentation showing pricing decisions remain under human control; (2) vendor-side records proving no data or rule-sharing occurs between competing operators; and (3) disclosure of model inputs that materially change what a guest sees and pays.

For chains already operating the systems, a practical audit checklist will likely include:

• A documented human override recorded for every algorithmic price or recommendation.
• Vendor contract language prohibiting data flows between franchisees or to competitors.
• Quarterly model audits producing pricing-output records by location.
• Board- or operations-level minutes showing retained local pricing authority.

Why this reaches beyond McDonald's

Drive-thru personalization platforms from vendors including Presto Automation, SoundHound and several large point-of-sale providers feed menus at multiple domestic chains. A ruling that shared-vendor AI pricing constitutes coordination would force those chains to renegotiate vendor agreements, segment data and rework contracts across thousands of franchise relationships.

Procurement teams evaluating new deployments should expect vendor sales conversations to change. RFPs will likely require software providers to certify that pricing logic is location-specific and human-supervised rather than centrally aggregated.

What's next

The case will proceed through initial motions in the coming months. A dismissal would mute the algorithmic-coordination theory for the foreseeable future; a denial of dismissal opens the case into discovery that pulls vendor contracts, model code and franchisee pricing data into the open. For an industry that has moved billions of dollars into ordering and menu automation since 2020, the answer will shape vendor procurement, contract language and the architecture of every menu-software RFP issued in the next 24 months.
