Overview

• Proceedings begin in Alexandria, Virginia, to set remedies after an April ruling that found Google monopolized publisher ad servers and ad exchanges through unlawful tying.
• The Justice Department asks the court to force a sale of Google’s AdX exchange, open‑source Google’s auction logic, and impose a 10‑year ban on operating an exchange after divestiture.
• Government filings also contemplate further structural steps if competition does not improve, including a potential future sale of Google’s publisher ad server.
• Google opposes divestiture as disproportionate and technically unworkable, proposing interoperability commitments, deprecating unified pricing rules, and ending first‑ and last‑look advantages instead.
• Executives from publishers and ad tech firms are slated to testify this week, with post‑trial briefing and closings expected by November and a final remedies ruling widely expected in 2026.
