Atlantic City Casino Price-Fixing Lawsuit Revived by Appeals Court

A federal appeals court has revived a proposed class-action lawsuit accusing major Atlantic City casinos of using an artificial intelligence platform to illegally inflate hotel room prices. The decision by the 3rd U.S. Circuit Court of Appeals in Philadelphia allows the antitrust case against operators including Caesars Entertainment, MGM Resorts, and Hard Rock to proceed.

The Allegations

The lawsuit claims the casino operators engaged in a price-fixing scheme by providing sensitive, non-public data to a third-party software provider, Cendyn. According to the plaintiffs, the casinos fed real-time pricing and occupancy information into Cendyn's Rainmaker platform.

The platform's AI algorithms then allegedly used this collective data to generate pricing recommendations, which the casinos adopted. The plaintiffs argue this system effectively created a digital cartel, allowing competitors to coordinate on higher room rates without direct communication, thereby overcharging customers in violation of federal antitrust law.

The Court's Decision

Wednesday's ruling overturns an October 2024 decision by U.S. District Judge Karen Williams, who had initially dismissed the case. The lower court found that the plaintiffs had not sufficiently shown how the casinos used the confidential data after submitting it to the software.

Ad

The 3rd Circuit panel, however, concluded the claims were adequate to move forward to the discovery phase, where plaintiffs can seek technical evidence. In its opinion, the court noted the potential for modern technology to facilitate anticompetitive behavior, writing, "AI software can facilitate collusion by enabling competitors to coordinate prices and share information without ever communicating with each other."

Context and Market Implications

This ruling places the 3rd Circuit at odds with another federal court, creating a split on the issue of algorithmic price-fixing. In August 2025, the San Francisco-based 9th U.S. Circuit Court of Appeals dismissed a similar lawsuit brought by casino customers in Nevada.

For investors, the revival of the Atlantic City case highlights growing legal and regulatory scrutiny over the use of AI-driven dynamic pricing tools. The outcome could set a significant precedent for how antitrust laws are applied in industries, such as hospitality and real estate, that increasingly rely on algorithms to set prices.
