In a significant legal development, a U.S. judge has dismissed the Department of Justice’s proposal to compel Google to divest its advertising exchange, AdX. This decision enables Google to maintain a crucial segment of its ad technology business. Judge Leonie Brinkema’s ruling allows Google to retain ownership of AdX while endorsing most of the restrictions suggested on the company’s conduct. The ruling comes in the wake of a 2025 verdict that determined Google had unlawfully preserved monopolies in the sectors of publisher ad servers and advertising exchanges.
The Justice Department, along with several U.S. states, contended that Google’s prior actions justified removing its control over AdX. However, Google argued against the enforced sale, citing the potential technical challenges and disruptions it could cause to its customers. The company maintained that separating the platform would be a complex process.
This decision marks another defeat for U.S. antitrust authorities in their efforts to dismantle dominant technology firms. Previous attempts to mandate asset sales in cases against other major tech companies have similarly been unsuccessful, reflecting the broader struggles regulators face in curbing the power of tech giants.
While Google’s advertising exchange remains intact, the ruling imposes behavioral measures aimed at addressing competitive concerns and the company’s interactions with publishers. These measures are intended to mitigate issues surrounding competition and ensure fairer treatment of publishers in the digital advertising landscape.
