EU Forces Meta to Let Rivals Use WhatsApp's AI Features

The European Commission has ordered Meta to give competing AI assistants — including OpenAI's — free access to WhatsApp. This is part of an ongoing investigation into whether Meta unfairly locks out rivals from its messaging platform.

Reuters reported on 9 June 2026 that EU regulators formally required Meta to allow competing AI chatbots to work with WhatsApp at no cost. The Commission published its order on 14 April 2026 under case AT.41034, specifically addressing whether Meta's practice of keeping AI rivals off WhatsApp breaks competition law.

How the Investigation Started

The European Commission opened its investigation on 3 December 2025. The core concern: Meta was stopping third-party AI assistants from accessing WhatsApp while allowing its own Meta AI to integrate freely. Since WhatsApp has over two billion active users globally, controlling who gets access to that platform gives Meta a significant advantage.

What stands out is how quickly the Commission moved. It took less than five months to go from opening the investigation to issuing this binding order. Normally, competition cases take years. But the Commission saw an urgent problem: if one company locks up AI integration on a dominant messaging platform now, it may be nearly impossible to break that monopoly later. AI assistants are spreading fast through messaging apps, and whoever owns that territory early has a big head start.

What Meta Now Has to Do

The Commission's order requires Meta to give competing AI assistants the same access it gives its own Meta AI on WhatsApp — and they cannot charge for it. This matters because Meta could technically comply by offering access at impossibly high prices. The "free" requirement closes that loophole.

This creates a technical puzzle. WhatsApp encrypts all messages end-to-end by default, meaning only you and the person you are messaging can read what you send. Building a system that lets other AI assistants access WhatsApp conversations without breaking that encryption is complex engineering work. The Commission's order does not yet spell out exactly how Meta should solve this. That question will likely come up as the case continues.

Why This Matters for AI Distribution

Here is why a company would fight hard to control WhatsApp's AI layer: messaging apps are where most people actually use AI now, not through separate apps or websites. WhatsApp sits at the centre of daily conversation for billions of people. If you can embed your AI assistant there, you get access to real conversations, contact lists, and usage patterns that a standalone app can never have. For OpenAI and other AI makers, that access is worth fighting for not because of direct revenue, but because of the data and real-world learning opportunity that come with operating at WhatsApp's scale.

This is not a new pattern. Two decades ago, the Commission fought Microsoft over bundling its web browser and media player with Windows. The argument then was the same: if you control the platform everyone uses (Windows), you can use that power to win in related markets (browsers, media software) and squeeze out rivals. The WhatsApp case follows identical logic — Meta controls messaging, and it is allegedly using that to dominate AI assistants. The main difference is the Commission is moving much faster this time, perhaps having learned that waiting years for a final decision lets one company's dominance become entrenched.

What Happens Next

Meta has not publicly accepted this interim order as final. The company is expected to fight parts of it as the underlying investigation continues. Interim measures are temporary — they stay in place while the case moves forward, but a company can appeal them to EU courts.

Meta is already juggling other EU rules. The company must comply with the Digital Markets Act and the Digital Services Act, which also impose their own access and transparency requirements. Whether this new WhatsApp order overlaps with those other rules, or runs on parallel tracks, is something EU lawyers will parse carefully. Too many overlapping rules can create confusion and create friction in how they are enforced.

The broader context here is worth noting: this action shows the Commission is willing to use interim relief as a real tool to shape AI market structure in Europe. A company considering an exclusive AI integration strategy on a dominant platform now has to factor in that the EU may move quickly to block it. That changes the calculation significantly.

For Meta operationally, the work is real. Building and maintaining an API (a technical interface) that lets other AI assistants access WhatsApp while preserving WhatsApp's own security is not trivial. Meta will have to staff and fund this alongside its own AI ambitions.

The investigation into whether Meta broke the law is still ongoing. A final decision on whether Meta violated competition rules — and what penalties or structural changes might follow — is still months or years away. But the interim order has already established one critical point: WhatsApp's AI layer is not Meta's private property anymore. It is now a regulated access point. How AI assistants get distributed inside closed messaging platforms across Europe will likely be shaped by this case for years to come.
