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.

The following post was originally included as part of our recently published memorandum “Selected Issues for Boards of Directors in 2024”.

Antitrust in 2023 was marked by a series of policy developments—some still nascent, some ripe for enforcement for the first time.  In the U.S., the FTC and DOJ finalized their drastically transformed merger guidelines.  In the EU, landmark new digital regulations became applicable for the first time.  And the UK government introduced a bill promising major new digital and consumer protection rules. 

Last year we noted that U.S. antitrust enforcement was in a period of nearly unprecedented public attention and policy debate, and also that the Biden Administration seemed likely to launch significant new policy initiatives as the year progressed. 

In the 2021 edition of this memo, we wrote that antitrust in 2020 received more political and media attention than at any recent time. 2021 beat that standard in multiple ways, and 2022 looks to continue that trend. In addition to continuing the major tech cases brought under the Trump administration, 2021 saw unprecedented levels of legislative activity in antitrust (both federal and state), competition policy taking a leading position across federal agencies and startling new approaches at the Federal Trade Commission (FTC) in particular – new approaches that, while they haven’t yet produced a wave of new enforcement actions, have required changes in thinking about and approaching antitrust issues. We expect these trends to accelerate in 2022.
