Google's Antitrust Trial: Remedies Phase Raises Key Questions
The remedies phase of Google's antitrust trial concluded after 11 courtroom days, offering observers a clearer view of Judge Leonie Brinkema's approach and potential remedies. The DOJ's proposal for a lengthy divestiture—reportedly up to 14 years—faced skepticism about imposing ongoing costs or engineering requirements. Brinkema questioned whether acquirers could offer the same products for free and explored alternative incentives, including vouchers or shifting buy-side products. Testimony from Google publishers and ad-tech executives highlighted burdens on small publishers and questions about open-sourcing Final Auction Logic. Several observers suggested behavioral remedies could be favored over a full divestiture. Next steps include settlement discussions before November's closing arguments, with a decision anticipated in late Q1 2026.

DOJ and Google Clash Over AdTech Remedies Ahead of Verdict
The DOJ and Google have filed updated post-remedy briefs in the ongoing antitrust case over Google's ad tech stack, with the sides sharpening their positions ahead of closing arguments. Google argues that divesting its sell-side AdX would be time-consuming and unnecessary, proposing to integrate Prebid with AdX for open web display ads while allowing bypass for video/CTV/in-app formats and certain programmatic packaging; it also pledges to maintain performance and reduce latency and information loss. The DOJ counters with structural relief to restore competition, including potential divestiture of AdX and DFP and an escrow fund to collect a share of net profits from Google’s ad tech businesses to aid publishers. It also proposed opening the Ad server logic and warned of disruptions to small publishers. Judges Brinkema and Mehta have raised questions about the remedies’ practicality and impact on publishers, shaping the debate over remedies and enforcement.
Judge Weighs Google's Ad Tech Future After Closing Arguments
Closing arguments in the DOJ v. Google ad tech antitrust trial have concluded, and Judge Leonie Brinkema will decide the fate of Google's sell-side ad tech business, AdX. The DOJ pressed for a structural remedy—divestiture of AdX—arguing that behavioral requirements would leave Google room to undermine the ruling, while Google contended that trust is at the core of the matter and that a full divestiture is unnecessary. Google's attorney, Karen Dunn, contrasted the DOJ's approach with the outcomes of the Google Search antitrust trial, suggesting a lighter, behavioral remedy could suffice. The judge voiced concerns about how quickly any remedies could take effect given rapid innovation in ad tech. A potential AdX buyer, such as Microsoft, was mentioned, though no ready acquirer was identified and a divestiture could trigger additional antitrust reviews. A decision is expected next year, with appeals likely.
