title: UK Regulator Probes Major Hotel Chains for Data Sharing
---

The UK's Competition and Markets Authority (CMA) has launched an investigation into major hotel chains Hilton, Marriott, and InterContinental Hotels Group (IHG). The probe will examine whether these companies have shared competitively sensitive information.

The CMA is scrutinizing the hotel groups' practices to ascertain if they have engaged in behavior that could distort competition within the hotel market. Such practices could potentially include the sharing of pricing or trading data that might allow competitors to coordinate their commercial strategies, thereby harming consumers.

The investigation is at an early stage, and the CMA has not yet reached any conclusions. The companies involved have been notified of the investigation.

## Key Takeaways

*   The UK's CMA is investigating Hilton, Marriott, and IHG.
*   The investigation focuses on potential anticompetitive data sharing.
*   The probe aims to determine if sensitive commercial information was exchanged between the hotel groups.

The CMA has the power to take enforcement action if it finds evidence of competition law breaches. Further updates are expected as the investigation progresses.
