The UK's Competition and Markets Authority (CMA) has initiated an antitrust investigation into Google Search, which holds over 90% of the market share in the UK. This marks the CMA's first official investigation of 2025, focusing on Google's AI search advancements and its extensive search advertising business. Stakeholders can submit comments until February 3. The CMA aims to assess whether Google creates barriers to competition and innovation while potentially misusing consumer data. Proposed remedies may include increased market access for competitors and even business restructuring.
