EU court deals a partial blow to Brussels over Meta
The EU’s top court has annulled Facebook Marketplace’s designation as a “gatekeeper” under the bloc’s landmark Digital Markets Act, ruling that the European Commission failed to adequately justify its decision. The legal setback carries limited immediate consequences — but its procedural implications deserve serious attention.
At a Glance
On June 3, 2026, the General Court of the European Union — the EU’s second-highest court — struck down Facebook Marketplace’s designation as a “gatekeeper” under the Digital Markets Act (DMA), finding that the European Commission had not properly supported its case.
The practical impact is limited: the Commission had already removed Marketplace from its gatekeeper list on April 23, 2025, after Meta restricted the platform’s commercial listings in July 2023, causing it to fall below the user thresholds required for designation.
Meta’s Messenger app retains its gatekeeper designation — keeping significant structural obligations in place, including requirements around interoperability with competing messaging services.

What is a “gatekeeper” under the DMA?
The Digital Markets Act, which entered into full application in March 2024, is the European Union’s primary tool for reining in the power of large digital platforms. It introduces a specific legal category: gatekeepers, defined as companies that control the critical entry point between business users and their end customers online.
The logic is straightforward. If a small business needs to use Facebook Marketplace to reach its potential buyers — because the platform is so dominant that there’s effectively no alternative — then Meta controls the digital front door and can set the terms of entry. Think of it as the online equivalent of a company owning the only highway into a major city.
Gatekeeper designation triggers a set of binding obligations: interoperability requirements, algorithmic transparency, and prohibitions on specific anticompetitive practices. Violations can result in fines of up to 10% of a company’s global annual revenue, and up to 20% for repeat offenses. For Meta, which reported $164.5 billion (approximately €150 billion) in revenue in 2024, the financial stakes are substantial.
What the court ruled — and what it did not
The ruling issued Wednesday in Luxembourg partially annuls the Commission’s September 2023 decision, which had designated Meta as a gatekeeper for both Facebook Marketplace and Messenger.
The court did not rule that Marketplace was not a gatekeeper. It ruled that the Commission had failed to make its case properly: on one hand, the Commission had not taken into account the changes Meta made to Marketplace in 2023 — notably restrictions on commercial listings introduced in July of that year — relying instead solely on data from the preceding three years; on the other, the decision lacked a sufficiently concrete analysis of how Marketplace actually operated after those changes, particularly on whether businesses could still effectively offer goods and services to consumers on the platform.
This is a failure of method, not an acquittal on the merits.
Messenger’s gatekeeper designation, by contrast, was upheld. That distinction matters: Messenger counts several hundred million active users worldwide, which suggests that keeping it within the DMA’s scope could prove more structurally significant in the long run than the fate of Marketplace.
A limited setback — but not a trivial one
The immediate impact of the Marketplace ruling is, in practice, narrow. The Commission had already removed the platform from its gatekeeper list on April 23, 2025, after Meta’s July 2023 restrictions caused it to fall below the required user thresholds. Wednesday’s ruling therefore arrives after the question had already, in effect, been resolved on its own.
But that is precisely where the setback carries deeper meaning. The fact that a core DMA designation was partially struck down by the EU’s own courts — not because Marketplace wasn’t a gatekeeper, but because the Commission failed to demonstrate its position with sufficient rigor — should prompt the EU’s executive arm to seriously examine the robustness of its initial assessments and its capacity to withstand legal challenges from technology companies with vast legal resources.
Meta has already felt the financial teeth of the DMA. On April 23, 2025, the Commission fined the company €200 million for failing to comply with DMA obligations tied to its “consent or pay” model — which regulators found did not give users a genuine choice over how their personal data would be used. Apple was fined €500 million on the same day for separate violations.
Analysis: when procedure becomes strategy
This case illustrates a structural tension that could weigh on DMA enforcement for years to come. The Commission designed an ambitious regulation with a broad scope — but its implementation has proven vulnerable to procedural challenges when individual decisions are not airtight.
American technology companies, whose legal resources dwarf those of the Commission’s enforcement teams, have every incentive to pursue this strategy systematically: not to challenge the DMA’s principles head-on, but to attack individual decisions on the grounds of legal reasoning and methodology.
Wednesday’s ruling hands Meta — and potentially others — a detailed roadmap of the gaps to exploit. It also signals that if the Commission wishes to redesignate Marketplace in the future (which remains possible should the platform again exceed the required user thresholds), it will need to build a significantly stronger factual record.
Messenger’s confirmed designation may ultimately prove more consequential than the Marketplace annulment. The interoperability obligations imposed on Messenger could theoretically, over time, allow users of other messaging services — such as WhatsApp or Signal — to communicate with Messenger contacts without switching platforms. That would represent a structural shift in Europe’s digital communications landscape, provided the Commission has the resources to actually enforce compliance.
The Bottom Line
The DMA is not in danger after Wednesday’s ruling — but it is being tested. The real question isn’t whether Meta won or lost in Luxembourg. It’s whether the European Commission is capable of sustaining a legal war of attrition against adversaries that have the time, the resources, and now a favorable precedent to sharpen their strategy.
Regulating Big Tech is a marathon. And on Wednesday, Brussels stumbled on a point of method.
