    The U.S. Court of Appeals for the 3rd Circuit ruled Wednesday that consumers had plausibly alleged an unlawful conspiracy involving casino companies and a revenue-management software platform that allegedly enabled competitors to align room prices. The decision overturns a lower court’s dismissal and sends the case back for further proceedings.

    The lawsuit was brought on behalf of hotel guests who claim they paid artificially inflated room rates because competing casinos relied on the same AI-powered pricing technology to recommend or optimize rates. The plaintiffs argue that the software effectively reduced independent pricing decisions, resulting in higher prices than would have existed in a competitive market.

    The appeals court did not determine whether antitrust violations occurred. Instead, it concluded that the allegations were sufficient for the litigation to continue, allowing the parties to move into discovery and potentially trial.

    The case adds to growing scrutiny over the use of algorithmic pricing systems across multiple industries. Antitrust regulators and private plaintiffs have increasingly questioned whether AI-based pricing tools can facilitate unlawful coordination even when companies do not communicate directly about prices.

    Businesses that rely on revenue-management software have argued that such tools help respond to market conditions more efficiently and do not, by themselves, constitute illegal price-fixing. The legal dispute is expected to test how traditional antitrust principles apply to modern AI-assisted pricing technologies.

    The revived lawsuit could become one of the most significant U.S. cases examining whether shared pricing algorithms expose companies to antitrust liability, particularly as artificial intelligence becomes more deeply integrated into commercial decision-making.
