Overview

• Judge Leonie Brinkema ruled Google illegally monopolized publisher ad servers and ad exchanges but did not hold a monopoly in advertiser ad networks.
• The court will now determine remedies, which could include structural changes like divestitures or policy adjustments to restore competition in ad tech markets.
• Google has announced plans to appeal the ruling, which could delay significant changes for years as legal proceedings continue.
• The decision highlights bipartisan antitrust momentum, with both the Biden and Trump administrations supporting efforts to curb Big Tech dominance.
• A separate remedies trial for Google’s search monopoly case begins April 21, potentially leading to broader impacts on its business operations.
