CMA Opens Chapter II Investigation into Meta's Commercial Terms, Targeting Potential Abuse of Dominant Position Over UK Publishers and Advertisers

The Competition and Markets Authority launched a formal investigation on 30 October 2026 into whether Meta Platforms is abusing a dominant position through the commercial terms it imposes on businesses that use Facebook, Instagram, and its other services. The investigation proceeds under Chapter II of the Competition Act 1998, which prohibits conduct by dominant firms that amounts to an abuse of their market position. The CMA's central concern is that Meta's terms could allow it to collect content from the websites of businesses and publishers that use its platforms, and then use that content to develop and provide its own products and services, including AI features, without those businesses having any meaningful choice. The authority describes this as a potential imposition of unfair trading conditions on thousands of UK businesses that depend on Meta's services to reach customers and audiences. Three entities are formally under investigation: Meta Platforms, Inc., Facebook UK Limited, and Facebook Ireland Limited. The CMA adds that other entities within Meta's corporate group, including relevant UK subsidiaries, may also fall within scope. The investigation was triggered partly by complaints from the News Media Association and the Movement for an Open Web. Meta had originally planned to introduce revised terms on 30 October but had already paused the rollout, moving the effective date first to 20 November and then suspending it entirely on 28 October to consult industry groups. The CMA opened its case regardless, and critically, the scope of the investigation extends beyond the paused revisions to cover Meta's existing commercial terms as well. Evidence gathering from Meta and third parties is scheduled to run from October 2026 through to January 2027. CMA chief executive Sarah Cardell stated that where a company holds a dominant position, it must not use that position to impose unfair terms, and pledged to work towards a swift resolution.
