EU Orders Meta To Reopen WhatsApp To Rival AI Chatbots

The European Commission issued an interim measure on June 9, 2026 ordering Meta Platforms to restore access for rival general-purpose AI chatbots to the `WhatsApp for Business API` within five working days, per the Commission press release and Reuters. The order requires reinstatement under the same terms and conditions that applied before Meta restricted third-party assistants, Reuters and BBC report. Reporting by multiple outlets notes this is the Commission's first interim competition measure in approximately 17 years, reflecting the urgency regulators attached to the AI-access dispute. The interim measure follows an antitrust investigation opened in December 2025 after complaints filed by The Interaction Company, French startup Agentik and a Spanish competitor, Reuters reports. The Commission warned that failure to comply could trigger fines of up to 10% of Meta's global turnover, according to Reuters and the Commission statement. EU executive vice president Teresa Ribera was quoted saying, "In rapidly evolving markets, competition can be lost long before a final decision is adopted," Reuters and BBC report. The Commission said the interim order will remain in place while the investigation continues, and at the latest until June 2029, per Reuters.

Meta updated its WhatsApp Business service terms in October 2025 to bar external standalone AI assistants from accessing the WhatsApp Business API infrastructure, per reporting by Reuters and technology.org. This restriction prompted the antitrust complaints that led to the December 2025 investigation and the June 2026 interim order restoring prior access.

Messaging platform APIs such as `WhatsApp for Business API` are commonly used by AI assistants to maintain persistent conversations, deliver notifications, or handle real-time customer queries. Industry-pattern observations note that when a dominant platform changes API terms or access policies, third-party integrators face engineering and compliance work to re-establish connections, manage rate limits, and map message formats to assistant backends. Restoring access under prior terms reduces short-term engineering lift for rivals, but long-term integration stability depends on durable, documented access rules and data-flow agreements between platform and assistant providers.

The Commission framed the intervention as necessary to prevent "serious and irreparable harm to competition" in a market where AI assistants may become primary consumer interfaces, per Reuters. The measure is notable because interim competition orders that force continued commercial access are relatively uncommon - the last such EU interim measure was roughly 17 years prior, multiple outlets note. For practitioners building assistant integrations, the ruling highlights regulatory risk as an axis of platform availability alongside technical and business risks.

The action drew an immediate rebuttal from Meta. Reporting by Reuters, BBC and TechJuice records a Meta spokesperson saying, "The European Commission has decided that OpenAI and some of the largest companies in the world can use the paid-for WhatsApp Business product for free," and adding "We will appeal," in statements circulated to media.

Monitor whether Meta complies within the five working days set by the Commission, and whether restored access mirrors prior API rate limits, message formats, authentication flows and commercial conditions. Industry observers should also watch the investigation outcome, any formal charges or remedies the Commission imposes, and whether similar interim measures are sought against other platform operators. If regulators increasingly use interim measures to preserve market access, companies that rely on closed platform APIs may need to factor legal and policy contingencies into product roadmaps.
