Advertisers Seek Mass Arbitration

Advertisers that bought Google ads are organizing thousands of private arbitration claims after two federal antitrust rulings found parts of Google’s search and ad-tech businesses unlawful. (claimsjournal.com) The first claims are expected to be filed this week, according to Chicago lawyer Ashley Keller, who said he has already signed up a “significant number” of advertisers. Keller told Bloomberg that economists working for the claimants estimate search and display-ad claims could reach $218 billion or more under one calculation. (claimsjournal.com) The cases are going to arbitration because Google’s advertising terms require binding individual arbitration instead of jury trials or class actions, unless customers opted out within 30 days. Google’s current advertising program terms say disputes must be resolved through “binding individual arbitration.” (payments.google.com) Mass arbitration is the workaround: instead of one class action, lawyers file many individual claims at once against the same company. The American Arbitration Association recorded 82 consumer mass arbitrations and 10 employment mass arbitrations in 2024, and Bloomberg reported the Google matter may be the first aimed at corporate claimants. (claimsjournal.com) The legal opening came from two court losses for Google. On August 5, 2024, Judge Amit Mehta ruled that Google illegally maintained monopolies in general search services and general search text advertising. (goodwinlaw.com) A second ruling followed on April 17, 2025, when Judge Leonie Brinkema found Google unlawfully monopolized the publisher ad server and ad exchange markets and unlawfully tied those products together. Those are the tools websites use to manage ad space and the marketplaces that match buyers with that inventory. (stblaw.com) Publishers have already started suing on the back of that ad-tech ruling. Bloomberg Law reported in February that companies including Vox, The Atlantic, Business Insider, McClatchy Media, Slate and Advance Publications had joined or filed private cases seeking damages in New York. (news.bloomberglaw.com) Google says it plans to fight. In a recent corporate filing cited by Bloomberg, the company said it faces private damages claims tied to antitrust cases worldwide, “cannot estimate a possible loss,” and believes it has “strong arguments” against the claims. (bloomberg.com) The immediate question is not whether Google can be sued again over the same conduct, but how many advertisers sign up and how much each says it overpaid. Keller told Bloomberg that similar mass arbitrations have taken 12 to 24 months from filing to resolution. (claimsjournal.com)
