A federal judge has dismissed the U.S. Department of Justice’s bid to compel Google to divest its advertising exchange platform, AdX. This decision permits Google to maintain a crucial component of its advertising technology operations. Judge Leonie Brinkema ruled against the forced sale of AdX but sanctioned most of the proposed limitations on Google’s conduct.
This judgment follows a landmark 2025 ruling that determined Google had unlawfully preserved monopolies within the markets of publisher ad servers and advertising exchanges. The Justice Department, along with several state governments, contended that Google’s historical actions justified its relinquishment of control over AdX. Conversely, Google argued that detaching the platform would pose significant technical challenges and potentially disrupt services for its customers.
The ruling marks another hurdle for U.S. antitrust officials who have been striving to dismantle dominant technology companies. Similar attempts to mandate asset sales in cases involving other large tech giants have also met with limited success.
In allowing Google to retain its advertising exchange, the court imposed behavioral measures designed to address competitive concerns and Google’s interactions with publishers. These measures aim to regulate Google’s conduct without necessitating the divestiture of its advertising technology assets.
