The European Commission issued an interim measure against Meta Platforms on Tuesday, ordering the company to restore rival AI chatbots’ access to the WhatsApp for Business application programming interface within five working days. The measure is the first of its kind from the Commission in 17 years and follows an investigation opened in December 2025 after complaints from three companies: The Interaction Company of California, developer of the Poke.com AI assistant; French AI startup Agentik; and a Spanish rival. The Commission issued formal charges against Meta in February, alleging breaches of EU antitrust rules. The interim measure arrived on the same day as Tuesday’s Anthropic infrastructure announcements and JPMorgan’s AI agent disclosure, making it the enforcement event of a day already dense with AI competition developments.
The specific conduct the Commission is addressing is straightforward. Meta blocked rival AI services from accessing the WhatsApp for Business API in October 2025, while simultaneously exempting its own Meta AI assistant from that restriction. In March 2026, Meta allowed competitors back onto the platform, but charged a fee for the access that had previously been available without one. That fee structure drew the Commission’s objection. Under the interim order, Meta must restore access on the same terms and conditions that applied before October 2025 – free – within five working days. The speed and severity of the instruction, framed as an emergency to prevent irreversible harm to competition, is what NewsTrackerToday picked up as the signal that distinguishes this order from a standard investigation.
Sophie Leclerc, who covers the technology sector, reads the competitive architecture of the ruling: “What the Commission is protecting is specifically the access point. WhatsApp has approximately three billion monthly active users globally, with particularly deep penetration in European markets. For any AI assistant trying to reach European consumers through messaging, being locked out of WhatsApp or forced to pay for access while Meta AI operates for free is not a minor commercial disadvantage. It is a structural entry barrier. The interim measure keeps the market open while the full investigation runs, which could take one to two more years to complete.”
Meta’s response was pointed. A company spokesperson described the Commission’s order as subsidizing OpenAI and some of the largest companies in the world through a paid-for product, at the expense of European companies that pay. The appeal announcement followed immediately. Meta’s commercial argument is that the WhatsApp Business API is a paid product and that forcing free access for competitors amounts to requiring Meta to subsidize its rivals. The Commission’s position is that Meta’s exemption of its own AI from the fee it charges competitors constitutes discriminatory abuse of a dominant messaging position. Both framings are legally coherent, which is what NewsTrackerToday noted as the reason this case will run through the courts regardless of how Meta complies with the five-day deadline.
EU antitrust chief Teresa Ribera’s statement framed the decision in terms that go beyond the specific complaint: “In rapidly evolving markets, competition can be lost long before a final decision is adopted.” That rationale – that the pace of AI market development requires enforcement tools faster than standard investigation timelines allow – is the stated justification for the interim power. The last time the Commission used interim measures was in 2001, against IMS Health, in a data market dispute. Twenty-five years later, the tool is being used again in an AI assistant distribution dispute, and the framing of WhatsApp as critical infrastructure for the AI market is what NewsTrackerToday zeroed in on as the regulatory theory that will define how far the Commission pushes this.
The potential fine of up to 10% of Meta’s global annual turnover for a confirmed antitrust breach, combined with the mandatory five-day compliance window, applies real commercial pressure regardless of appeal. Meta’s turnover for 2025 was approximately $200 billion, making the theoretical maximum penalty $20 billion. That number is ceiling rather than floor, and final fines in EU antitrust cases are typically a fraction of the maximum. But the combination of an emergency interim order, a public appeal announcement, and an investigation that could run for two more years is what News Tracker Today connects to a larger shift in EU digital competition enforcement: Brussels has decided that waiting for markets to settle is no longer the dominant strategy when the market in question is AI.
