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.
