The Ninth Circuit dismissed antitrust claims against Las Vegas hotels and software provider Cendyn, ruling that independent use of algorithmic pricing tools doesn’t constitute unlawful price-fixing under the Sherman Act. The court found no coordinated conduct or restraint of trade, diverging from the DOJ’s broader interpretation. While businesses may adopt pricing algorithms, they must avoid collusion. The decision sets key boundaries for antitrust liability in the context of AI-driven pricing strategies.
