On October 20, 2020, the U.S. Department of Justice and 11 state attorneys general sued Google under the Sherman Antitrust Act, alleging that the company used exclusive or exclusionary agreements with Apple, mobile carriers, and Android manufacturers to preserve its dominance in general search and search advertising. The DOJ estimated that Google controlled about 88% of the U.S. general-search market and more than 70% of search advertising. At trial, witnesses testified that Google paid roughly $10 billion annually to retain default status, including on Apple’s Safari browser. Google denied coercion, arguing that users chose its services because they were superior.
After a trial that began on September 12, 2023, Judge Amit Mehta ruled on August 5, 2024, that Google had illegally maintained monopolies in general search services and general text advertising. The DOJ later sought structural remedies, including possible divestiture of Chrome or Android, while Google called the proposal excessive. In September 2025, Mehta declined to order those divestitures but barred exclusive search-default contracts and required Google to share certain search-index and user-interaction data with competitors. Google and the DOJ appealed different portions of the judgment as of early 2026, leaving the final remedy—and its implications for other Big Tech antitrust cases—unresolved.
