Google defeats U.S. bid to force ad tech sale

In an April 2025 ruling, a U.S. judge found that Google holds illegal monopolies on ad-serving servers and the ad exchanges that connect advertisers and publishers. The decision raises antitrust and potential remedy/regulatory risk around Google’s ad-tech infrastructure, which could pressure business economics and compliance costs. Near-term impact is more likely to weigh on sentiment than to immediately change ad revenues, but it is material for ad-tech competitive dynamics.
