The U.S. Department of Justice (DOJ) has initiated a high-stakes antitrust trial against Google, alleging that the tech giant has illegally monopolized the digital advertising and search markets. In a separate but related case, Judge Amit Mehta ruled that Google had abused its monopoly power over the search industry and set a timeline for determining penalties, with a decision on remedies expected by August 2025. Possible penalties could include breaking up Google's adtech tools or limiting deals that make Google's search engine the default on devices. Prosecutors are also considering the future landscape of AI in search, as they prepare their comprehensive remedial proposals. Google’s defense argues that the DOJ's market definitions are outdated and not reflective of the current digital advertising ecosystem.
