The European Union has escalated its antitrust scrutiny of Meta Platforms, warning it may impose interim measures over the company’s decision to restrict rival artificial intelligence (AI) services from operating on WhatsApp. The move represents one of Brussels’ strongest signals yet that it is willing to act quickly when it believes dominant digital platforms are using their scale to shape emerging markets in their favour.
In this case, the market in question is consumer-facing AI services, where competition is still forming and early advantages can be difficult to unwind. In a statement released on Monday, the European Commission said it had formally charged Meta with breaching EU competition rules by limiting access to WhatsApp’s ecosystem.
Why regulators are moving early
According to the Commission, Meta implemented a policy change on January 15 that allows only its in-house AI assistant, Meta AI, to operate on WhatsApp, effectively excluding competing AI developers from the platform.
The Commission has issued a statement of objections — a formal document outlining its preliminary view that Meta’s conduct violates EU competition law. While Meta is entitled to respond before a final decision is reached, the language used by regulators suggests growing concern that a lengthy investigation could allow irreversible market damage.
“The Commission therefore intends to impose interim measures to prevent this policy change from causing serious and irreparable harm on the market, subject to Meta’s reply and rights of defence,” the EU executive said.
Interim measures are relatively rare and typically reserved for cases where regulators believe delay would entrench dominance. Their use here underlines the Commission’s view that WhatsApp’s scale gives Meta an immediate structural advantage in AI distribution—one that rivals may struggle to overcome if left unchecked.
WhatsApp as an AI distribution choke point
At the centre of the dispute is WhatsApp’s role as one of Europe’s most widely used digital platforms, with hundreds of millions of users across the region.
By restricting AI access on WhatsApp to Meta AI alone, regulators argue that Meta may be leveraging its control of a core communications service to shape competition in an adjacent market. In effect, WhatsApp becomes a privileged launchpad for Meta’s AI ambitions, while rivals are denied a comparable route to users.
For the Commission, the concern is not just exclusion but timing. AI services are still in an early adoption phase, and distribution advantages gained now could translate into long-term market dominance, a pattern the EU has previously sought to prevent in areas such as search, mobile operating systems, and app stores.
A familiar regulatory fault line
This latest clash fits into a broader pattern of intensifying EU oversight of Meta’s business model.
In April 2025, the Commission found Meta in breach of the Digital Markets Act (DMA), a landmark regulation aimed at curbing the power of dominant “gatekeeper” platforms. That ruling focused on how Meta links services and processes user data across Facebook, Instagram, and WhatsApp.
In response, Meta announced plans to give EU users greater control over how their personal data is shared for advertising purposes, including options to limit cross-platform data use. The move followed months of regulatory engagement but did little to slow enforcement momentum.
More recently, the EU entered a tougher phase of DMA enforcement, imposing its first major fines under the law. Apple was fined €500 million, while Meta received a €200 million penalty tied to data-use practices — reinforcing the message that compliance commitments alone may no longer suffice.
What this case could change
For Meta, the immediate risk lies in the Commission’s willingness to impose interim measures. If enforced, Meta could be required to open WhatsApp to competing AI services while the investigation continues, limiting its ability to use exclusivity as a competitive lever.
A final adverse ruling could also bring significant fines and behavioural remedies, potentially shaping how Meta integrates AI across its platforms in Europe.
More broadly, the case could set an important precedent for the AI economy. As dominant platforms race to embed proprietary AI tools into messaging, search, and social products, regulators are signalling that control over distribution channels will be scrutinised as closely as the AI technology itself.
For the EU, the message is increasingly clear: in fast-moving digital markets, waiting for harm to fully materialise is no longer an acceptable regulatory strategy.
