BRUSSELS — For two years, Facebook Marketplace was the test case for whether Europe’s signature digital competition law could tame the largest platforms. The European Commission designated it a core platform service under the Digital Markets Act, ordered Meta to change how it treats data, and made it a symbol of the DMA’s ambitions. This week, an EU court took the opposite view of a different part of the law: Marketplace, the court ruled, is not a gatekeeper service at all, and is exempt from the DMA’s obligations.
The ruling is narrow and precise, and that precision is the story. The court found that Marketplace does not meet the DMA’s definition of a gatekeeper platform, even though the same court let the designation stand for Messenger, Meta’s messaging service, which must still comply with the law’s requirements. The two decisions, issued together, show a court applying the statute’s technical definitions rather than its political mood, and the distinction matters to every technology company doing business in Europe.
The practical consequence for Meta is significant. Marketplace can continue to use the data advantages that come from being part of Facebook, including the ability to connect buyers and sellers using behavioral information gathered across the platform. Under the DMA’s original designation, that advantage was exactly what regulators wanted to restrict. The court’s ruling removes the restriction for Marketplace, leaving Meta with more freedom in the classifieds business that has become a meaningful part of its advertising revenue.
The partial nature of the victory is equally instructive. Messenger remains subject to the DMA, and Meta must continue to make its messaging service interoperable with competitors’ services and to comply with data-sharing rules. The company asked the court to overturn both designations and won one. The outcome confirms that the DMA operates case by case, service by service, rather than as a blanket regime for anything a big platform touches.
For the broader technology industry, the ruling is a reference point. The DMA was drafted as a precise instrument, defining gatekeeper status through quantitative thresholds and specific service categories, and the court has now shown it will enforce that precision even when it produces a result regulators dislike. Companies that argued their services were caught by the law by accident have a template for their own challenges. Companies that expected the law to function as a general restraint on platform power have been told otherwise.
The Commission’s response will determine how much the ruling changes in practice. The European Commission can re-designate Marketplace if its characteristics change, and it can pursue the same conduct through other parts of the legal toolkit, including the DMA’s investigations and the older competition rules. Regulators have spent two years building a narrative around the DMA’s success; a court decision that removes one of its flagship cases forces a recalculation of what the law can realistically deliver.
Meta’s broader European posture gives the ruling its context. The company has been in conflict with EU regulators over data transfers, privacy rules, and its advertising model for years, and it has repeatedly argued that European regulation treats American platforms more harshly than European ones. A court victory, even a narrow one, gives Meta a legal foundation for that argument in future proceedings, and it arrives at a moment when the company is investing heavily in AI across its apps.
The competitive angle cuts the other way. Marketplace’s rivals in Europe, including classifieds businesses that operate only on the continent, have watched the case closely, and they argued that Marketplace’s data advantages distort competition. The court’s ruling leaves those rivals without the DMA as a weapon, though they retain the option of complaining under traditional competition law. For them, the case shows that winning a regulatory fight requires more than being on the right side of the argument; it requires fitting the statute’s definitions.
For Messenger, the work of compliance continues. The DMA requires designated messaging services to offer interoperability with smaller rivals, a technical obligation that has taken years to define and is still being negotiated with the Commission. Meta has argued that opening Messenger’s end-to-end encryption to third parties would undermine security, a position that regulators have acknowledged while still requiring progress. The court’s split decision leaves Meta in the unusual position of appealing one ruling and complying with the other, and the company’s engineering teams will now be building to the obligations the court confirmed.
The ruling’s most durable effect may be procedural. Europe has become the testing ground for digital regulation, and every enforcement action, court challenge, and legislative adjustment is studied by regulators elsewhere. The DMA was supposed to be Europe’s answer to the platforms’ power, and the court has now defined the limits of that answer. The lesson, for regulators and for companies, is that the law will be enforced as written, not as imagined, and that precision cuts both ways.
