Advertisers sue Google
A wave of advertisers is pursuing mass arbitration claims that Google maintained illegal monopolies in search and ad tech, with potential damages running into the billions. Legal advisers expect arbitration to take 12–24 months and say the exposure could prompt buyers to re-examine platform dependency. (bloomberg.com)
Advertisers are moving claims against Google out of court and into mass arbitration, seeking payouts that legal advisers say could reach billions. (bloomberg.com) Bloomberg reported on April 13 that companies that bought Google ads, including USA Today Co. and Advance Publications Inc., are joining coordinated arbitration demands tied to Google’s search and advertising technology businesses. Lawyers organizing the claims expect the process to take 12 to 24 months. (bloomberg.com) Mass arbitration means many companies file separate arbitration cases at the same time instead of one class action in court. ClassAction.org, which is recruiting advertisers, says the claims center on allegations that Google suppressed competition in display advertising and drove up ad prices. (classaction.org) The push gained force after two federal antitrust losses for Google. In August 2024, Judge Amit Mehta ruled that Google illegally maintained monopolies in general search and search text ads, and the Department of Justice said a later remedies order barred exclusive distribution contracts and required Google to share some search data with rivals. (justice.gov) A second case hit Google’s ad business on April 17, 2025. The Department of Justice said Judge Leonie Brinkema found that Google unlawfully monopolized key advertising technology used by publishers and ad exchanges, though later coverage of the ruling said the court rejected the government’s claim on advertiser-side buying tools. (justice.gov) (bloomberglaw.com) That split matters for the advertisers’ theory of harm. The publisher-side ruling still described a market structure in which Google controlled important pipes for buying, selling, and auctioning web ads, and claimant lawyers are using that record to argue advertisers paid more than they would have in a competitive market. (simpsonthacher.com) (classaction.org) Google has argued the ad tech market is competitive and that publishers and advertisers use its tools because they are effective and affordable. After the April 2025 ruling, reports on Google’s response said the company pointed to the court’s rejection of one part of the government’s case as support for its position. (variety.com) (bloomberglaw.com) The arbitration campaign also shows how antitrust findings can turn into private damages claims. Bloomberg Law reported in February that large publishers were already piling into separate civil suits against Google after the ad tech ruling, and the advertiser filings extend that pressure to the companies that bought inventory through Google’s systems. (bloomberglaw.com) For advertisers, the immediate question is not whether Google will be broken up this year. It is whether a 2024 search monopoly ruling and a 2025 ad tech monopoly ruling are enough to make thousands of individual claims expensive enough that media buyers start spreading budgets more aggressively beyond Google.
