Google avoided the breakup of its advertising-technology business when a federal judge declined to order sale of its AdX ad exchange.
The decision substitutes regulatory constraints for a forced divestiture, endorsing interoperability remedies and other operational limits while leaving Google, the Mountain View search and advertising company, in control of its ad stack.
The ruling closes a long-running antitrust fight that began with a Department of Justice lawsuit in January 2023 and followed an April 2025 finding that Google had illegally monopolised parts of the ad-tech market.
The judge also required immediate technical changes to how the exchange interoperates with rivals and signalled a role for court supervision of compliance.
Industry groups reacted quickly, with the Computer & Communications Industry Association posted a reaction to the court's remedies.
How the ordered interoperability and oversight are implemented will determine whether regulators pursue further structural relief in the case.
