Overview
- U.S. District Judge Leonie Brinkema found Google guilty of monopolizing the publisher ad server and ad exchange markets for open-web display advertising.
- The ruling allows prosecutors to seek structural remedies, potentially forcing Google to divest its Google Ad Manager platform, which includes its ad server and ad exchange tools.
- Google plans to appeal the decision, arguing that publishers have alternative ad-tech options and that its tools are competitive and effective.
- The judge dismissed claims that Google held a monopoly in the advertiser ad network market, citing insufficient evidence from antitrust enforcers.
- This decision follows a separate 2024 ruling where Google was found to illegally monopolize the online search market, with a trial on search remedies set to begin next week.
