PubMatic, Inc. , an independent technology company delivering digital advertising’s supply chain of the future, filed a lawsuit in the U.S. District Court for the Eastern District of Virginia against Google to seek financial damages and to restore fair competition, following years-long harm caused by Google’s proven and repeated monopolistic and anticompetitive behavior in certain digital advertising markets.

The lawsuit follows the ruling from the U.S. District Court in April 2025, which found that Google had “willfully engaged in a series of anticompetitive acts to acquire and maintain monopoly power in the publisher ad server and ad exchange markets for open-web display advertising.”

PubMatic’s complaint outlines how Google’s illegal actions directly and measurably impacted PubMatic, impeding the Company’s ability to reach its full potential in terms of market share and revenue growth and compete on a level playing field. Google’s dominance both deprived publishers and advertisers of the benefits of fair competition and caused real damage to consumers in the form of higher prices due to advertising cost increases, less diversity of content and voices, and less transparency.

“For nearly two decades, PubMatic has delivered sustainable innovation and efficiency in digital advertising, empowering publishers to maximize their revenue and deliver quality content to users worldwide,” said Rajeev Goel, PubMatic’s co-founder and CEO. “Google’s systematic abuse of its vast resources and immense power has harmed our business and distorted a marketplace that should have rewarded innovation and fueled transparency and competition. Instead, anticompetitive practices limited monetization for publishers, raised costs for advertisers, and ultimately reduced choice for consumers.”

Goel continued, “Since founding PubMatic almost 20 years ago, our vision has been to fuel the endless potential of content creators on the open internet, delivering superior technology and transparent practices. Over that time, we have built our business on industry-defining innovation, differentiated infrastructure, and a relentless focus on delivering better services for publishers and advertisers alike. This litigation positions PubMatic, and the broader industry, for stronger long-term growth by holding Google accountable for its past anticompetitive actions and monopolistic behaviors.”

In addition to holding Google responsible for its unlawful actions, PubMatic also seeks to restore a competitive and fair landscape, where innovation thrives, competition is real, and the open internet remains a source of information and opportunity for everyone.
