Google loses its final appeal on the €4.1 billion Android antitrust fine

The Court of Justice of the European Union has dismissed Google’s final appeal against a €4.1 billion ($4.7 billion) antitrust fine over its use of Android to lock in Chrome and Google Search as the defaults on the world’s dominant mobile OS. It’s the last word on a case that opened in 2018; the penalty stands.

The mechanism the Commission punished — bundling a browser and a search engine into the operating system so the default becomes the market — is the same lever now drawing fresh scrutiny as browsers turn into the surface where agents act. Whoever owns the default owns the funnel, and the EU has affirmed, at its highest level, that it will treat that ownership as an antitrust matter rather than a product decision.

Worth filing less for the number than for the precedent. This is a market-structure marker, not a trust-beat story — but the default-placement power it turns on is exactly what’s in play as the browser becomes the agent’s cockpit.
