A U.S. judge has decided against mandating Google to divest its advertising exchange platform, AdX, despite the Department of Justice’s push for such a measure. This decision allows Google to maintain control over a significant component of its advertising technology operations. Judge Leonie Brinkema approved most of the proposed limitations on Google’s business conduct but opted not to enforce the sale of AdX.
This ruling comes after a 2025 verdict determined that Google had unlawfully sustained monopolistic positions in the markets for publisher ad servers and advertising exchanges. In light of this, the Justice Department, along with several U.S. states, argued that Google’s historical actions justified removing its control over AdX. However, Google contended that separating AdX would present technical challenges and potentially disrupt their customers’ operations.
The verdict marks another challenge for U.S. antitrust officials who are attempting to dismantle large technology companies. Previous efforts aimed at breaking up other major tech firms have similarly not succeeded in compelling asset sales.
While the ruling permits Google to retain its advertising exchange, it also imposes behavioral conditions designed to alleviate concerns about competition and how Google interacts with publishers. These measures aim to address issues related to Google’s dominance in the advertising sector without necessitating a structural breakup.
