Europe's General Court in Luxembourg dismissed Apple's challenge to its Digital Markets Act gatekeeper designation on Wednesday, rejecting the company's argument that its five App Stores — spanning iPhone, iPad, Mac, Apple TV, and Apple Watch — should not be treated as a single core platform service. The ruling keeps Apple subject to strict DMA obligations, including a ban on self-preferencing, restrictions on combining user data across services, and a requirement to allow alternative app stores on its devices.

The court also upheld the European Commission's classification of iOS as a gateway platform, meaning Apple must ensure rival services can interoperate with the operating system. Apple had separately contested the labeling of iMessage as a number-independent interpersonal communications service, which would bring it under EU telecom regulations, but the tribunal ruled that challenge inadmissible.

To qualify as a gatekeeper, a company must meet thresholds including €7.5 billion in annual EU revenue or a €75 billion market capitalization, alongside 45 million monthly active users and 10,000 active business users in the bloc. Apple clears these bars comfortably, and the decision reinforces the EU's willingness to enforce structural remedies against dominant platforms.

The loss limits Apple's ability to delay DMA compliance and signals that similar challenges from other designated gatekeepers — such as Meta and Google — face steep odds. For consumers, the ruling accelerates the arrival of third-party app stores and interoperable messaging on iOS, though Apple's implementation timeline and technical restrictions will determine the practical impact.
