The European Commission opened a formal investigation into Booking.com on October 21, 2026, over concerns it may have failed to adequately address fraudulent listings, phishing scams, and advertising transparency, issues officials described as "absolutely substandard". The probe could lead to fines of up to 6% of the company's annual worldwide turnover if violations of the Digital Services Act (DSA) are confirmed.

This investigation matters to millions of travelers across the European Union who use Booking.com to find accommodation. It shows the Commission's commitment to making Very Large Online Platforms accountable under the Digital Services Act, working to create safer online environments and transparent advertising practices for consumers.
