Overview

• U.S. District Judge Leonie Brinkema opened a two-week remedies hearing in Alexandria after finding in April that Google unlawfully monopolized ad servers and exchanges, with a decision expected in the coming months.
• The Justice Department seeks a divestiture of Google's AdX exchange, open-sourcing of the auction mechanism, and a 10-year bar on operating an ad exchange after any sale.
• Google argues a breakup is "radical and reckless," says divestiture is technically unworkable and harmful to publishers and advertisers, and proposes interoperability and data‑export commitments instead.
• Prosecutors say only structural relief will restore competition, and they propose further action—up to a sale of the publisher ad server—if competition is not restored within four years.
• The court is weighing Judge Amit Mehta's recent search-case remedy that rejected a Chrome divestiture, while EU enforcement—including a €2.95 billion fine and a 60-day fix deadline—adds external pressure.
