UK's CMA launches investigation into Hilton, IHG and Marriott
The UK's Competition and Markets Authority (CMA) has launched an investigation into Marriott, Hilton, IHG Hotels & Resorts, and STR's owner CoStar Group over suspected sharing of competitively sensitive information through the use of STR. The initial investigation is expected to run for six months until August. The CMA emphasized no assumptions of law-breaking, but could issue a statement of objections if competition law is infringed. CoStar and IHG said they will cooperate fully. A similar class-action lawsuit in the U.S. was dismissed in August 2025.
