The day the EU ordered Meta to
host rival AIs for free.
WhatsApp Business has become the backbone of customer support for European companies. Meta keeping its own grip on which AI chatbots can run there—the European Commission saw this as "shutting out competition" and, for only the second time in 20 years, reached for its emergency powers. We unpack what happened, and why it carries such weight, through diagrams.
From "under investigation"
straight to "corrective order"
In December 2025, the European Commission formally opened an antitrust investigation into Meta. The core issue: the suspicion that Meta was blocking third-party AI chatbots on WhatsApp Business to give its own Meta AI an advantage. At the time it was still only "under investigation," and any corrective measures were expected to be months away.
But this time, as an extension of that investigation, the European Commission ordered Meta, as an interim measure, that "WhatsApp must re-host rival AI assistants for free." The basis for the decision was to prevent "serious and irreparable competitive harm" in the market for general-purpose AI assistants. It is a forceful stance—acting first, without waiting for a final ruling.
| Until now (through end of 2025) | This interim measure |
|---|---|
| Still "under investigation" | A concrete corrective order |
| Rival AIs blocked | Rival AIs hosted for free |
| Remedy expected months away | Acted before any conclusion |
| Meta AI effectively dominant | More freedom to choose a channel |
Regulators pried open the
gateway to competition—without waiting for a final ruling.
The weight of "emergency powers"
used twice in 20 years
The EU has reached for this interim measure only twice in more than 20 years. That alone shows how serious it considers the problem.
A normal antitrust process follows a sequence: investigation → final ruling → remedy. This time, midway through that process, the powerful tool of an interim measure was deployed. "By the time a conclusion arrives, the rivals may have already vanished from the market"—it is an emergency move to avoid that kind of irreparable harm.
If Meta does not comply with the order, it also faces the risk of fines. In other words, this decision confronts Meta's very rollout of its AI business in the EU market with the highest level of regulatory risk it has faced so far.
Who is affected, and how
The contrast in impact is clear. The more you use WhatsApp for work, the more directly the change reaches you.
Marketers
If you use WhatsApp as a channel, room opens up to build customer support around chatbots other than Meta AI. You gain more freedom in choosing your channel.
Engineers
For those building services on the WhatsApp Business API, a path opens for rival AI bots to come in. Your design options expand.
Everyone else
If you don't use WhatsApp for work, the direct impact is light for now. Still, it's worth noting as a sign of where regulation is heading.
A starting gun against
"platform AI lock-in"?
WhatsApp Business was already deeply embedded in the customer-support infrastructure of European companies. On top of that, Meta could centrally control whether AI chatbots running there were allowed to connect—and the EU judged this very structure to be "shutting out competition." Now that general-purpose AI assistants are becoming the gateway to daily life and work, who controls which gateway has become the heart of the competition.
This order is a symbolic move by regulators stepping into the design choices by which giant platforms favor their own AI. Both Meta's response going forward and the uncertainty around AI businesses in the EU market are well worth watching from here on.
