Google has run out of road in one of the longest and largest antitrust fights in tech history.

Europe's highest court, the Court of Justice of the European Union, on July 2 upheld an antitrust fine of about €4.1 billion (roughly $4.7 billion) against Google over its Android operating system, Bloomberg reported. The ruling exhausts Google's appeals and locks in what remains the largest antitrust penalty the EU has ever imposed.

What Google was penalized for

The case dates to 2018, when the European Commission — the EU's competition regulator — fined Google €4.34 billion, finding it had abused the dominance of Android (which runs the vast majority of the world's smartphones) to entrench its own search engine, the Commission said at the time. Regulators focused on how Google required phone makers to pre-install Google Search and its Chrome browser as a condition of licensing the Google Play app store, and paid some manufacturers to install Search exclusively — steps that, the EU said, shut out rivals. (Antitrust law polices anti-competitive behavior; in Europe, "abuse of a dominant position" — using market power in one area to squeeze competition in another — is illegal under the bloc's rules.)

The long road to a final ruling

Google fought the penalty for years. In 2022, the EU's General Court largely backed the Commission but trimmed the fine by about €200 million, to roughly €4.1 billion. Google appealed again to the Court of Justice — and lost. The court's decision is final, with no further appeal.

Why it matters

For Google, the fine is manageable relative to parent Alphabet's earnings, but the legal defeat matters more than the money: it cements a precedent that its Android practices broke EU law, and it lands amid other European scrutiny of the company. For Big Tech broadly, the ruling reinforces that the EU will punish "tying" — using control of one product to prop up another — and signals continued aggressive enforcement, now amplified by newer tools like the Digital Markets Act aimed at dominant "gatekeeper" platforms. That marks a sharp contrast with the historically lighter-touch U.S. approach, and it shapes how the world's largest technology companies must operate in a market of nearly 450 million consumers. Boursel takes no side in the litigation, which is now closed; the takeaway is that Europe has, once more, drawn a hard line on how far a dominant platform can go to defend its turf — and made it stick at the highest court.
