Antitrust in 2024 was marked by evolving policy developments, vigorous enforcement, and eye-catching court decisions. In the U.S., an aggressive enforcement approach lead to unpredictability and lengthy merger review process across sectors. In the EU, enforcement of the Digital Markets Act (DMA) intensified scrutiny on digital platforms, while a landmark ruling in the Illumina/GRAIL matter clarified the scope of the EU Commission’s merger jurisdiction. In the UK, the Competition and Markets Authority (CMA) cleared the Vodafone/Three merger with behavioral remedies, signaling a significant departure from its historic practice to require structural remedies. 2025 will see new antitrust leadership on both sides of the Atlantic with an expectation that the U.S. will largely return to a more traditional approach on antitrust under the Trump Administration and that Europe will continue to enforce digital rules and bring cases related to AI with a focus on promoting growth in clean tech and AI sectors.
