EU Commission imposes interim measures on Meta

On June 9th, 2026, the EU Commission announced that it is imposing interim measures on Meta while the investigation on a possible abuse of dominance is carried out. The antitrust investigation, opened in December 2025, means to evaluate the legality of Meta’s revised policy which blocks access for AI providers, other than Meta AI, to WhatsApp.[1]

INDEX

FACTUAL BACKGROUND

Meta, formerly known as Facebook, acquired WhatsApp in 2014. The merger was given the greenlight by the EU Commission after an extensive study on possible anticompetitive effects in three different relevant markets: consumer communication services, social networking services, and online advertising. The assessment was based on information and promises shared by Facebook regarding the unlikelihood of automated matching between Facebook users’ accounts and WhatsApp users’ accounts following the merger. Nevertheless, in 2016, WhatsApp announced updates to its terms of service and privacy policy, including the possibility of linking WhatsApp users’ phone numbers with Facebook users’ identities.[2] The Commission reacted by fining Facebook €110 million for providing misleading information about the takeover after finding that, contrary to Facebook’s statements from 2014, its staff were aware of the possibility of matching the platforms’ accounts and identities.

Facebook infringed Regulation 1/2003 by intentionally or negligently providing the incorrect or misleading information to the Commission. The fine was meant to act as a deterrent proportional to the nature, gravity and duration of the infringement, after taking into consideration all mitigating and aggravating circumstances. It was the Commission’s first ever decision involving the imposition of fines on a company for providing incorrect or misleading information since the entry into force of the 2004 Merger Regulation. There were no other measures taken aside from the fine and the merger continued to set Facebook (now Meta) on the course toward achieving and maintaining a dominant position status. This is the status that proves problematic for the current event.

In October 2025, Meta announced that it would update its WhatsApp Business Terms, effectively banning third-party general purpose Artificial Intelligence (“AI”) assistants from the consumer communication application. The Commission has considered WhatsApp to hold a dominant position in the market since at least January 2023. Therefore, the update to the Terms is considered, at first sight, to be a possible abuse of dominant position, as competing general-purpose AI assistants are precluded from using the platform’s Business Application Programming Interface (“API”).

Starting mid-January 2026, the only AI assistant available on WhatsApp was Meta’s own AI tool (“Meta AI”). The complete exclusion of all competitors was lessened on March 4th, when a revision of the policy accepted third-party general-purpose AI assistants again on the platform, but levied an access fee which is being classified as a practice possibly equivalent to the previous access ban. Teresa Ribera, executive Vice-President of the Directorate-General for Competition, stated that the fees were so elevated that they could not be economically sustained by competitors.

Formal proceedings were opened by the Commission in December 2025. The decision to initiate antitrust proceedings covered the EEA except for Italy, as the Italian National Competition Authority (AGCM) imposed its own interim measures on Meta in December. Shortly after, a Statement of Objections was released, setting out the Commission’s preliminary view that Meta breached EU antitrust rules by excluding third party AI assistants from accessing and interacting with users on WhatsApp.[3] Meta’s conduct risks blocking competitors from entering or expanding in the rapidly growing market for AI assistants.

April 2026 marked the expansion of the investigation to Italy, allowing the study to analyze conduct changes since the initiation of proceedings.

Meta’s response denounces the opening of the investigation as they find that the Commission’s approach imposes unfair conditions, allowing “OpenAI and some of the largest companies in the world [to] use the paid-for WhatsApp Business product for free,” a Meta spokesperson said in an email.[4] An appeal will be filed by Meta as they find the investigation to be a “regulatory overreach subsidized by many European companies that pay.”

The substantive investigation into the merits of the case is still active and ongoing.

The investigation of case AT.40134 [CD1] is carried out through the lens of the antitrust laws set out in Article 102 TFEU and Article 54 of the EEA Agreement which prohibit the abuse of dominant positions that may affect trade and prevent or restrict competition within the Single Market.

The proceedings are carried out within the rules and limitations set out by Article 11(6) of Council Regulation No. 1/2003 (Cooperation between Commission and National Authorities)[5] and Article 2(1) of Commission Regulation No. 773/2004 (Initiation of Proceedings)[6].

Pursuant to Article 8(1) Regulation 1/2003, interim measures may be imposed in cases of urgency due to the risk of serious and irreparable damage to competition assessed on a basis of a prima facie finding of infringement. Although such measures are always imposed for a limited amount of time, they can be renewed until the end of the investigation (by June 2029 at the latest for the case at hand).

Meta faces a potential fine of up to 10% of its total turnover in the year preceding the alleged infringement if found to have breached the EU antitrust regulation and may also be subject to daily periodic penalty payments not exceeding 5% of the average daily turnover in the business year preceding the infringement if it does not comply without delay.

THE INTERIM MEASURE

The Commission has concluded that interim measures are warranted to prevent serious and irreparable damage to competition in the growing market for general-purpose AI assistants as Meta holds a dominant position in the market for consumer communication applications and is, at first sight, abusing this position by blocking access to the WhatsApp API. The refusal to provide access to an infrastructure developed for and previously open to third parties created an urgent need to prevent damage to the competition structure of the AI assistant market by stalling the growth of smaller players and new entrants that could possibly challenge large incumbents.

The decision orders Meta to re-instate access for third-party general purpose AI assistants to the platform’s Business API and to re-establish the same terms and conditions that were enforced before the policy change in October 2025, when access to the Programming Interface was free of charge. Those terms are meant to be enforced until the Commission adopts a final decision on the case. Compliance must be immediate, as Meta has five days to implement the measure.

Meta may also appeal the decision ordering the interim measures before the EU Courts pursuant to Section 17 of the Commission Antitrust Manual.

IMPORTANCE OF THE DECISION

Although Regulation No. 1/2003 expressly provides for the ability to impose interim measures if, at first sight, there is an infringement of competition law rules, this is only the second decision imposing such measures since 2019. The first and last instance of application of Art. 8(1) was in relation to the Broadcom case (AT.40608). Broadcom was found to have engaged in exclusionary practices and was subject to the first enforcement of interim measures implemented by the Commission. The interim measures decision, which had an implementation duration of three years, was shortly followed by a commitment decision (ex Art. 9 Regulation No. 1/2003) reflecting commitments offered by Broadcom and revised through a market test. Indeed, the commitment decision built on the applied interim measures, extending their effects for an additional seven years. Furthermore, the commitments covered additional areas of the market and more service providers who were in business with Broadcom.[7] Since then, the Commission has only once announced the possible use of interim measures in an investigation on potential competition restrictions on Lufthansa transatlantic routes to and from several airports in the EEA area[8], but it ultimately decided to abandon its request.

We may conclude that interim measures and commitment decisions are connected, as the former appear to suspend problematic behaviors and create incentives for the company under investigation to quickly find a lasting solution to the identified concerns. A commitment decision may also result in the Commission closing the investigation and simply monitoring the status, implementation, and results of said commitments.[9] Although the Commission may, upon request or of its own initiative, reopen the proceedings (e.g. if the undertaking concern acts contrary to their commitments), the prospect of closing the investigation early is a favourable one for the undertakings concerned. No reasonable economic agent wishes to remain involved in an investigation that can span years, under constant hawk-eye monitoring, and possible heavy fines and remedies.

It seems opportune to now start keeping an eye on other future uses of interim measures by the Commission as a tool to push undertakings to step back in line promptly in a way that spares time, money, and other resources that would otherwise be spent on a lengthy investigation. The transition from the monitoring of the implementation of interim measures to the monitoring of commitments is natural and efficient and it is something we are likely to see more of in future antitrust and competition regulation enforcement.
