Advertisers are starting mass arbitration claims against Google, seeking damages tied to court rulings that found parts of its search and ad businesses were illegal monopolies. (bloomberg.com) Bloomberg reported on April 13 that Chicago lawyer Ashley Keller had signed up a “significant number” of advertisers and expected the first claims to be filed this week. He estimated potential claims tied to search and display ads at $218 billion or more. (bloomberg.com) The claims are being routed into arbitration because many Google advertiser contracts require disputes to be handled outside court. A federal judge in New York ruled on January 24, 2025, that two advertisers who accepted Google’s terms had to arbitrate their antitrust claims. (mediapost.com) Mass arbitration means many separate claimants file at once instead of bringing one class action. ClassAction.org says advertisers who bought Google display ads are being recruited into that process, with lawyers seeking treble damages under antitrust law. (classaction.org) The legal opening came from two federal antitrust defeats for Google. In Washington, a federal court found in 2024 that Google illegally monopolized online search, and in Virginia, the Justice Department said on April 17, 2025, that it had prevailed in its ad-tech monopolization case against Google. (bloomberg.com) (justice.gov) That ad-tech case centered on the tools that place ads on third-party websites. The Justice Department said publishers rely on those tools to buy and sell ad space, and the court held that Google monopolized open-web digital advertising markets. (justice.gov) Private plaintiffs have also gained leverage in court. DLA Piper said Judge P. Kevin Castel ruled on October 27, 2025, that findings from the Virginia case could carry over into consolidated private litigation brought by publishers, advertisers and other plaintiffs in New York. (dlapiper.com) Google has said it plans to fight the claims. Bloomberg reported that the company said in a recent corporate filing that it could not estimate a possible loss from private antitrust damage claims and believed it had “strong arguments” and would defend itself vigorously. (bloomberg.com) The arbitration campaign could take time even if filings begin this week. Keller told Bloomberg that similar mass arbitrations have taken 12 to 24 months from filing to resolution, leaving Google and ad buyers facing a new legal front while appeals and private damages cases keep moving.
