A U.S. judge has dismissed a proposed consumer class-action lawsuit accusing several major Las Vegas hotels, including Caesars Entertainment, of sharing price information through a third-party platform to artificially inflate room rental rates. Chief US District Judge Miranda Du in Las Vegas ruled that the plaintiffs failed to prove any conspiracy existed. The decision marks a significant victory for the Strip hospitality companies accused of antitrust behavior. The Nevada Federal Court's dismissal of the second version of the lawsuit also raises questions about the legality of algorithmic pricing in the hospitality industry.
