Meta Platforms stock faces fresh EU test over WhatsApp AI access

Meta Platforms is challenging a European Commission interim order that requires WhatsApp to restore free access for rival artificial-intelligence assistants. The action was published in the Official Journal on Monday, November 9, 2026, under Case T-521/26.

The Official Journal of the European Union identifies Meta Platforms, Inc. as the applicant and the European Commission as the defendant. Meta asks the General Court to annul the Commission's decision in full or, alternatively, to remove provisions requiring free WhatsApp Business API access, banning fees and imposing periodic penalty payments.

Legal challenge targets AI access rules

The dispute follows the Commission's June 9, 2026 decision in Case AT.41034, titled Exclusion of AI Competitors from WhatsApp. The interim measures were adopted under Article 8(1) of Regulation 1/2003 while the Commission's antitrust investigation continues.

Meta argues that the Commission applied the wrong legal framework when assessing market definition, dominance and the potential exclusionary effects on the European Economic Area market for general-purpose AI assistants. The filing also contests the necessity and proportionality of the interim measures and says the order lacks sufficient reasoning for imposing free access.

According to MLex, the appeal argues that there is no prima facie breach of European market-power rules. The legal challenge does not determine the final outcome, but it keeps the conditions for third-party AI access on WhatsApp in focus for investors.

Meta Platforms stock traded at 575.55 euros on Lang & Schwarz at 1:46 p.m. CET on Tuesday, November 10, 2026.
