Teads Sues Google for Damages, Citing 6.88 Trillion Lost Ad Impressions

Teads Holding Co. (Nasdaq: TEAD) said Aug. 3 it has sued Google LLC and Alphabet Inc. (together, "Google") in the U.S. District Court for the Southern District of New York, seeking financial damages and other relief. The lawsuit follows a prior ruling from the Eastern District of Virginia that found Google engaged in illegal anticompetitive conduct and monopolization in certain digital ad-tech markets. As of after-hours trading Aug. 3, Google (GOOGL) was at $373.51, up 4.88% (+$17.38) from the prior close of $356.13, with an opening price of $365.445 and an intraday range of $363.35 to $376.6932.^{[GlobeNewswire]}

The Virginia Antitrust Ruling Is the Backbone of This Case

Teads argues in its complaint that Google's exclusionary ad-tech practices directly stifled fair competition in digital advertising, capping the growth and revenue potential of independent platforms, publishers, and advertisers. As a player in the global ad-tech ecosystem, Teads says it filed this suit to hold Google accountable for historical market distortions and claw back losses tied to Google's alleged illegal conduct.^{[GlobeNewswire]}

The suit leans directly on the April 17, 2025 ruling by Judge Leonie Brinkema of the Eastern District of Virginia, which found Google monopolized the publisher ad server and ad exchange markets for open-web display advertising and illegally tied the two. Per the complaint, that ruling followed a three-week trial with 39 witnesses testifying in person and 20 more providing depositions. The court found Google "willfully engaged in a series of anticompetitive acts to acquire and maintain monopoly power" in those markets.^{[PPC Land]}

Notably, a ruling from this same New York court on Oct. 27, 2025 gave the Virginia findings preclusive effect — meaning private plaintiffs no longer need to prove liability and can move straight to damages and calculation of compensation.^{[PPC Land]}

The Core of the Complaint: 6.88 Trillion Lost Impressions and Seven Claims

According to PPC Land, Teads' complaint runs 85 pages, was filed as Case No. 1:26-cv-06591 in the Southern District of New York, and details how Google's bundling of Google Ads with AdX hurt excluded exchanges — costing Teads roughly 6.88 trillion ad impressions.^{[PPC Land]}

The complaint brings seven claims, two of them under Section 2 of the Sherman Act, targeting the general publisher ad server market and the ad exchange market for open display advertising. Teads is represented by Kellogg, Hansen, Todd, Figel & Frederick, P.L.L.C., with John Thorne signing the complaint, and is demanding a jury trial.^{[PPC Land]}

Teads CEO David Kostman said in a statement: "Teads was founded to help publishers connect with leading advertisers and maximize revenue through innovative formats, premium user experiences, and scalable monetization technology. For years, Google has leveraged its dominance to suppress fair competition and distort the digital ad-tech ecosystem for its own benefit. We are bringing this lawsuit to recover the financial harm Google's illegal conduct has caused our business and to restore a transparent, competitive marketplace for publishers and advertisers."^{[GlobeNewswire]}

The European Front: A $1B Fine and a Wave of Claims

The lawsuit lands as Google faces mounting antitrust pressure globally. Per MediaPost, the European Commission last week fined Google more than $1 billion for violating the Digital Markets Act (DMA), ordering Alphabet to dismantle preferential treatment for its own ad and content services and mandating structural changes across ads, search, and apps.^[MediaPost]

The report notes that over the past decade, the Commission has piled more than €10 billion (roughly $11 billion) in fines on Google, many still under appeal. According to six lawyers and litigation funders interviewed by Reuters, those cases have triggered a wave of suits from smaller rivals across six countries, with more in the works. Private claims could total as much as $10 billion, including a €2.97 billion claim from Italy's Moltiply Group and a roughly $1.97 billion award in the Stockholm PriceRunner case.^[MediaPost]

Thomas Hoppner, a partner at Geradin Partners, told Reuters: "I think this will trigger a new wave of lawsuits." Hoppner advised German price-comparison site Idealo in its market-abuse suit, which yielded a €465 million ruling against Google from a Berlin court last November — the largest antitrust damages award ever handed down by a German court. He expects specialist search companies may reach back to periods before the new rules took effect, seeking damages under Article 102 of the Treaty on the Functioning of the European Union, which bars abuse of a dominant market position.^[MediaPost]
