trivago N.V. (NASDAQ: TRVG) filed an antitrust damages claim against Google LLC and its subsidiaries before the Regional Court of Hamburg, Germany, the company announced.

The claim seeks compensation for damages trivago alleges it suffered due to Google's conduct in the hotel metasearch market. trivago contends that Google systematically favored its own hotel metasearch service in general search results pages, disadvantaging competing services. The claim is based on Article 102 of the Treaty on the Functioning of the European Union and related German competition law provisions prohibiting dominant companies from abusing their market position.

The claim covers January 2014 through December 2025 and seeks monetary damages based on independent expert analysis. trivago also requests disclosure of relevant traffic and revenue data held by Google, plus a declaratory judgment establishing Google's liability for damages from January 2026 onward.

"For more than a decade, we have raised concerns about Google using its dominance in general search to systematically steer millions of travelers away from hotel metasearch platforms like trivago and toward its own competing service," said Johannes Thomas, CEO and Managing Director of trivago.

trivago bases its claim on the EU Commission's 2017 decision in Case AT.39740, where Google was fined for abusing its dominant position by favoring its own comparison-shopping service. The EU Court of Justice upheld this decision in September 2024. The EU Commission is currently investigating Google for potential non-compliance with the Digital Markets Act's ban on self-preferencing.

Several damages claims based on the EU Commission's decision have progressed through European courts, including two first-instance awards by the Regional Court of Berlin II in November 2025.

trivago acknowledged that litigation outcomes are uncertain and the company expects to incur significant legal costs in connection with this claim.
