News Summary:

Magnite filed a federal antitrust lawsuit against Google on September 16, 2025, seeking financial damages due to Google's alleged illegal monopolization of digital advertising technology markets. The lawsuit alleges Google's anticompetitive conduct harmed Magnite over more than a decade. A US District Court ruled in April that Google “wilfully engaged in a series of anticompetitive acts to acquire and maintain monopoly power” in ad exchange and ad server markets. Magnite, described as the largest independent sell-side platform in the advertising industry, accuses Google of unlawfully monopolising ad exchange and publisher ad server markets. Google denies these allegations. Magnite's lawsuit contends Google systematically rigged digital advertising markets to stifle competition.
