Advertisers seek mass arbitration

Advertisers are trying to force Google into mass arbitration, turning recent antitrust court wins against the company into direct claims for money. (bloomberg.com) The effort targets companies that bought display ads through Google’s systems, including advertisers such as Gannett, the owner of USA Today, and Advance Publications, Bloomberg reported on April 13. Lawyer Steve Berman told Bloomberg potential damages could reach $218 billion or more. (bloomberg.com) Mass arbitration is a process in which many separate claimants file individual arbitration demands at once instead of joining one class action in court. Berman told Bloomberg those cases often take 12 to 24 months from filing to resolution. (claimsjournal.com) The claims build on two major antitrust rulings against Google in the last two years. In August 2024, a federal judge ruled that Google illegally maintained a monopoly in online search, and on April 17, 2025, Judge Leonie Brinkema ruled that Google illegally monopolized key ad-tech markets. (justice.gov, stblaw.com) The ad-tech case focused on the tools that place and sell digital ads: software used by publishers to manage ad space and exchanges that run the auctions. Brinkema found Google monopolized the publisher ad server and ad exchange markets, according to summaries of the ruling. (justice.gov, jenner.com) That matters for advertisers because the argument is not just that Google beat rivals, but that its control over the ad-buying machinery raised the prices buyers paid. ClassAction.org says lawyers are gathering advertisers who used Google’s Display Network to pursue arbitration over allegedly inflated ad costs. (classaction.org) Google has already used arbitration clauses to keep some advertiser disputes out of court. In January 2025, a federal judge in New York sent antitrust claims from two advertisers to arbitration under Google’s terms. (mediapost.com) Private plaintiffs have been moving quickly since the ad-tech ruling. Bloomberg Law reported in February 2026 that publishers were piling on with damages suits after the Virginia decision, and other ad-market companies such as PubMatic have also sued Google. (news.bloomberglaw.com, economictimes.indiatimes.com) Google has said its ad-tech tools are “simple, affordable and effective” and has argued that the government’s case would make it harder for publishers and advertisers to grow. The company said after the April 2025 ruling that it had won part of the case and would appeal the rest. (variety.com, jurist.org) The next fight is less about whether Google broke antitrust law than about how much that conduct cost the companies that bought ads. Mass arbitration is the vehicle those advertisers are now trying to use to collect. (bloomberg.com, claimsjournal.com)
