UK watchdog opens probe into three hotel chains and CoStar over data sharing
📈 UK Competition and Markets Authority launched a probe in March 2026 into Marriott, Hilton, IHG, and CoStar for potentially harmful data sharing affecting competitive rates. The investigation examines if sensitive data was shared via CoStar's analytics tool, breaching competition laws. CoStar insists its platform has been used for decades to evaluate market dynamics. IHG and Hilton confirmed cooperation, while Marriott hasn't commented. A similar lawsuit in 2025 was dismissed.
