A U.S. federal judge has ruled on antitrust remedies regarding Google’s illegal monopoly in the digital advertising market. While the Department of Justice sought to force the company to divest its AdX advertising exchange, the court rejected a structural breakup.

In a ruling from the Eastern District of Virginia, Judge Leonie Brinkema opted for behavioral remedies instead. These mandates may require Google to restrict self-preferencing tactics, provide competitors with real-time bid data, or end certain exclusivity privileges to ensure its advertising tools are interoperable with competitors. The court found that while Google unlawfully maintained monopolies in the publisher ad server and ad exchange markets, structural separation was not the necessary solution.

The specific details of these requirements will remain under seal for 14 days to allow for the redaction of confidential information, and both parties are expected to submit a joint proposed final judgment within 30 days.

Google expressed satisfaction with the ruling, stating that the rejection of a breakup protects tools that help small businesses grow. The Department of Justice indicated it is evaluating next steps, noting that the court order provides substantial relief toward restoring competition.
