Judge rejects Google ad breakup, mandates business practice changes

A federal judge ruled that Google can keep its advertising business but must adjust its practices to benefit competitors. The decision follows an earlier finding that Google illegally maintained a monopoly in ad tech. Specific remedies remain under seal for 14 days, and Google called the outcome a win.
The ruling continues a pattern established in Google's separate search antitrust case, where Judge Amit Mehta also declined to order structural breakups. In both instances, courts found Google had violated antitrust law but opted for behavioral remedies rather than divestiture, leaving the company's core business intact while imposing operational constraints.
The ad-tech case centered on Google's exclusive agreements with device manufacturers and revenue-sharing deals with mobile carriers, which the government argued cemented Google's default search position across phone markets. Judge Brinkema's full remedy order remains sealed for two weeks pending redactions, meaning the specific required practice changes are not yet public.
This decision could shape how antitrust remedies are applied to dominant tech platforms, signaling that courts may prefer targeted behavioral fixes over structural breakups. Small businesses relying on digital advertising may see modest changes in how ad tools operate, though the practical impact remains uncertain. Consumers could experience subtle shifts in search and ad experiences, but the ruling's sealed specifics mean tangible effects may take time to materialize.
