Alphabet shares surge after judge rejects DOJ breakup bid

Shares in Google parent Alphabet jumped sharply after a federal judge declined to order the company’s breakup in the Department of Justice’s long-running antitrust case, citing the emergence of new competitive pressures from artificial intelligence tools.

U.S. District Judge Amit Mehta on Wednesday rejected the DOJ’s remedy proposal that would have required Alphabet to divest its Chrome browser and the Android mobile operating system. The decision also allows the company to continue making payments to partners, including Apple, to set Google as the default search engine, a core focus of the government’s claims that Google maintained an illegal search monopoly.

Alphabet shares rose 8.8% on the day, a move that market commentators said added roughly £200 billion to the company’s market value. The stock reaction reflected relief among investors that the immediate prospect of a structural breakup — a remedy sought by the DOJ after a prior finding that Google had maintained an unlawful monopoly in online search — will not occur.

The DOJ had argued that Google’s agreements and conduct, including payments to device makers and browser vendors, foreclosed rivals and preserved its dominant position in online search. The department proposed the sale of Chrome and Android as part of a remedy package intended to restore competitive conditions in search advertising and related markets.

In his ruling, Mehta said that the landscape has been altered by the rapid development of AI-driven search alternatives and chatbots, which create new forms of competition for traditional search engines. The judge concluded that a forced divestiture was not necessary to address the competitive harms identified in the earlier finding.

Analysts lauded the decision for clearing a major regulatory hurdle. Dan Ives of Wedbush Securities described the outcome as a "massive win" for the companies involved, a reference widely interpreted to include both Alphabet and its distribution partners that had been affected by the proposed remedies.

The ruling resolves the immediate question of structural remedies but leaves unresolved broader legal and regulatory scrutiny of major technology firms. Industry observers noted that while the decision removes the threat of a break-up for now, it does not eliminate ongoing concerns by regulators about platform power, search advertising practices and the competitive effects of default search arrangements.

For investors, the judgment removes a headline risk that had weighed on valuations of Alphabet and other large technology companies. For regulators, the decision underscores the influence of rapidly evolving technology — particularly generative AI — on how courts assess market competition and appropriate remedies.

The DOJ may consider its legal options following the ruling. Meanwhile, Alphabet will be able to continue its existing business arrangements as the company and its partners navigate the post-ruling market and regulatory environment.
