Google Keeps AdX After Antitrust Ruling: What Publishers Should Expect

A US judge rejected the government's demand to force Google to sell its ad exchange, AdX, after an antitrust ruling, though Google must change some business practices. The decision raises questions about regulators' ability to limit Big Tech power. Judge Leonie Brinkema in Virginia declined to order the sale, instead accepting behavioral measures like giving competitors access to real-time bidding information. This follows an April 2025 ruling that Google held illegal monopolies and harmed publishers by pushing them toward AdX. For publishers, AdX remains under Google's control for now, with potential changes to competition unclear. The full ruling is expected to provide more details on how the new rules will affect the advertising market.
