The European Commission ordered Meta on June 10 to stop blocking rival AI chatbots from the WhatsApp for Business API, declaring on competition grounds that Meta had abused its dominant position in European messaging. The order is interim, in force while a full antitrust investigation runs. It restores the access rules that existed before October 2025.
That October 2025 policy change is what triggered this chain of events. Meta updated its API terms to make Meta AI the only chatbot permitted on the platform, eliminating third-party assistants that had previously been allowed to send notifications, order alerts, and automated messages through WhatsApp. Companies offering competing AI products were locked out of the largest messaging surface in Europe overnight.
The Commission opened an antitrust investigation in December and warned Meta earlier this year that interim measures were possible. Meta attempted to soften the standoff in March by offering paid API access to third-party AI assistants. The Commission rejected that offer. Competition chief Teresa Ribera, as reported by the Wall Street Journal, told journalists she considered the proposed fee too high. The Commission’s published rationale states that paid access is not preferable to the outright ban because the fee itself can function as a foreclosure mechanism.
Engadget reported the Commission’s language on urgency directly: “In rapidly evolving markets, competition can be lost long before a final decision is adopted.” That framing is deliberate. It signals the Commission believes that waiting for a final ruling would allow irreversible market concentration in AI-on-messaging to set in. The interim order is therefore structural, not procedural.
Meta has said it will appeal. Its argument is real and worth taking seriously: the order forces Meta to give some of the world’s largest AI companies free access to infrastructure Meta financed and operates, with no compensation. That is not a frivolous claim. The question regulators and courts will have to answer is whether dominance in a messaging network creates an obligation to subsidize competitors on that network, at least in the short term.
What makes this order different from the agent-distribution battles playing out elsewhere is the mechanism. Apple opening iMessage to third-party agents and Microsoft embedding assistant functionality inside Microsoft 365 are decisions those companies made voluntarily, on their own terms, on their own timelines. The EU did not wait for Meta to choose. A regulator overrode the platform owner and restored a baseline that the platform owner had unilaterally removed. That is a different kind of precedent.
If the investigation concludes with a finding that Meta violated competition law by restricting WhatsApp API access to its own AI product, the precedent extends beyond messaging. The same legal logic could apply to any dominant consumer surface where the platform owner controls both the distribution layer and a competing AI product. Search, mobile operating systems, and app stores each present analogous structures. The WhatsApp order is the first case where that theory has been applied at interim-measures level to an AI distribution dispute.
For teams currently building AI assistants that reach consumers through business messaging channels in Europe, the practical near-term effect is restored API access. The longer-term signal is that regulators are willing to move at speed when they believe AI distribution markets are tipping irreversibly.
