The European Commission has decided that AI assistants on smartphones are too important to leave to one company—and that ruling will reshape how the mobile industry works. In a Digital Markets Act decision released Monday, Brussels ordered Google to stop giving Gemini preferential treatment over competing AI services on Android, forcing the company to open system-level AI features to third-party developers by summer. This is not merely a regulatory slap at Google. It is a formal declaration that mobile AI assistants function as platform bottlenecks, the same way app stores and payment systems do under existing DMA rules.
The commission spent months examining how Android handles AI integration and concluded that Google's built-in Gemini enjoys access that no third-party service can match. Users who turn on a Google-powered phone find Gemini already there, embedded at the system level, with capabilities unavailable to alternatives. The commission identified this arrangement as an unfair advantage that violates the DMA's mandate requiring gatekeepers to treat third parties equally on their platforms. Google immediately labeled the decision "unwarranted intervention," but the company has called every DMA requirement unwarranted intervention since the law passed. That objection carries less weight now after years of enforcement.
What makes this ruling significant is its logic, not its immediate scope. The commission is extending the gatekeeper framework from traditional bottlenecks—app stores, browsers, search—to AI assistants, which increasingly serve as the primary interface between users and smartphones. If an AI assistant controls which apps get recommended, which services get invoked, and which data gets processed, then controlling that assistant is controlling the platform itself. The DMA was designed precisely for this kind of leverage, and the commission just drew that circle around Gemini.
Google will appeal, and the changes will not take effect until summer at the earliest, giving the company time to negotiate implementation details. But the direction is clear. Handset makers who want to ship their own AI assistants without Gemini's feature disadvantages now have legal standing to demand system access. Independent developers who have watched Gemini receive deeper OS integration can point to this decision as precedent. The commission is not ordering Google to kill Gemini or stop building AI features. It is ordering that whatever Google builds into Android must also be available to competitors on equal terms.
The deeper stake is whether AI assistants become a new front in platform regulation or remain a Google-controlled channel. Apple's decision to keep its own AI features exclusive to iOS has not yet attracted the same scrutiny, partly because the commission's DMA designation covers Alphabet but not Apple. That asymmetry will not last. Once the commission establishes that AI assistants are gatekeeper bottlenecks subject to competition law, the same logic applies to any dominant player. Google knows this. That is why it is fighting so hard to keep the bottleneck closed.
