Google will escape a forced breakup of its advertising technology empire after a US federal judge rejected the Justice Department's bid to compel a sale of the company's AdX exchange.

US District Judge Leonie Brinkema, sitting in the Eastern District of Virginia, issued her remedy decision under seal on Tuesday, accompanied by a short public order. In it, she denied the Justice Department's request to force Google to divest AdX, its flagship ad exchange. Instead, she ordered proposed behavioral changes to Google's business practices, though her order did not describe what those remedies entail. A redacted version of the full decision is expected to be made public later this month.

The ruling marks a pivotal moment in one of the most significant US antitrust cases targeting a major technology company in decades. The case, brought by the Justice Department together with a coalition of states, concerned Google's dominance in the digital advertising technology stack — the tools publishers use to sell ad space and advertisers use to buy it. Ad tech is a significant but smaller revenue driver for Alphabet than search advertising, and the outcome shapes how much regulatory pressure the company's display-advertising business will face going forward.

In April 2025, Brinkema found that Google had unlawfully monopolized key parts of the ad tech market, holding that the company owned the dominant tools on both the publisher and advertiser sides of the transaction as well as the exchange in between, and had tied them together in ways that harmed competition.

The Justice Department had sought sweeping structural remedies, including the forced divestiture of AdX, arguing that behavioral fixes alone would be insufficient to restore competition in a market where Google also operates other major ad tech products. Google countered that its advertising tools are integrated and beneficial to customers, and that a breakup would damage the business and slow innovation.

Behavioral remedies, the path the judge has now chosen, typically impose restrictions on how a company conducts its business — such as requirements around interoperability, data use, or dealings with rivals — rather than forcing the sale of assets. Antitrust enforcers have historically been skeptical of this approach, arguing that such remedies require long-term judicial supervision and can be circumvented; the Justice Department's preference for structural relief in recent tech cases reflects that critique.

The decision spares Alphabet, Google's parent company, from one of the most aggressive antitrust punishments sought against it in recent years, though the specifics of the ordered behavioral changes remain to be seen until the redacted ruling is published. The ad tech case is one of several major antitrust actions against Google in the US, alongside a separate Justice Department case over its search business, meaning the company still faces significant legal exposure on other fronts. What to watch next is the publication of the redacted decision, any appeal by either side, and how the ordered remedies are implemented and enforced.
