Google's Antitrust Battles: Guilty but Unbroken in 2025
AdExchanger assesses Google's 2025 antitrust trajectory: the company faced guilty findings in both a search monopoly and a publisher ad tech monopoly, and Europe imposed fines, but no divestitures materialized. In the DOJ’s search case, Judge Amit Mehta ordered Google to share search data with qualified competitors, yet imposed no divestiture or major changes to Google Search. In the publisher ad tech suit, the DOJ seeks divestiture of AdX and possibly DFP within Google Ad Manager, but remedies phase observers remain skeptical a court will mandate a break-up. European regulators are in a holding pattern pending Judge Brinkema’s decision. The piece notes a possible 2026 divestiture of AdX that could decouple the Ad Exchange from the ad server, reshaping market dynamics. Separately, Europe has eliminated Unified Pricing Rules; the US is eyeing a partial end to UPR for open-web display ads, with potential gains for publishers and developers.

Judge Rules Google Won’t Have to Break Up Ad Tech Business
Judge Leonie Brinkema ruled that Google illegally monopolized publisher ad-server and ad-exchange markets, but rejected the DOJ's proposed structural remedies, including divestiture of AdX and DFP. Instead, she imposed behavioral remedies largely based on Google's own proposals, requiring AdX to bid into Prebid via API integrations, mandating non-discriminatory bidding by Google Ads, eliminating UPR in the US, and banning first/last look. Google must share real-time bid data with publishers and stop AdWords from bidding directly into DFP or favoring Google's tools. The remedies apply globally but exclude video, in-app, and retail media, and do not require open-sourcing auction logic. A technical monitor will oversee compliance for six years with quarterly reporting. The ruling favors large exchanges and publishers with technical resources, while the DOJ lost on including DV360 and video/in-app inventory. Google retains AdX and DFP but intends to appeal. This parallels Judge Mehta's 2024 search decision, marking a second illegal monopoly finding without a breakup. Separate EU fines, state AG cases, and civil lawsuits continue.
