Meta opens WhatsApp to rival AI chatbots under EU pressure

Meta’s decision to reopen WhatsApp to rival AI chatbots is a revealing moment in the platform phase of the AI race. For a few months, Meta looked ready to run a classic “walled garden” play: push Meta AI as the only agent sitting on top of a three‑billion‑user messaging network and use that distribution to box out OpenAI, Anthropic and a long tail of vertical bots. EU and Brazilian antitrust regulators have now forced a partial retreat, at least for a year.

Practically, this opens a massive distribution channel for third‑party agents inside one of the world’s most important communication surfaces. Even with API fees and restrictive terms, the ability for non‑Meta models to live inside WhatsApp keeps the multi‑model ecosystem alive on mobile, rather than allowing a single incumbent to lock in users at the UI layer. Longer term, it’s a reminder that competition law is going to shape not just which AI wins on quality, but who gets to sit closest to the end user.
