Teads, the Nasdaq-listed omnichannel ad platform, filed an antitrust lawsuit against Google and Alphabet on August 3 in the Southern District of New York, seeking damages for what it says was years of lost auction volume caused by Google’s ad tech monopoly.
The complaint leans on a federal court’s prior finding, from the Eastern District of Virginia, that Google engaged in unlawful anticompetitive conduct in ad tech markets. Teads’ filing calculates that if Google Ads had bid into rival exchanges the way its own DV360 does, competing exchanges, including Teads’ own SSP, would have won 6.88 trillion more impressions between 2017 and 2023. The complaint also cites Google’s roughly 60% AdX market share and more than 90% share of the publisher ad server market as evidence of the tie it says foreclosed competition. CEO David Kostman said Google “used its dominance to suppress fair competition and distort the digital ad tech ecosystem to its own advantage.”
Why it matters for the marketing leader: Teads is not the first to file. It joins Magnite, OpenX, and PubMatic in bringing private damages claims off the back of the same underlying ruling, and the cases have now been consolidated in the same New York court. That turns a court finding into a reusable damages template, meaning the ad tech supply chain your media team buys through faces active litigation risk, the same pressure already pushing holding companies like Stagwell to build their own supply-side layers.
The original insight here is what is not being litigated yet: none of the four plaintiffs so far represent the DSP side of the market, meaning the remedy fight is currently one-sided toward publishers and sell-side platforms, not the agencies and brands that also transact through Google’s stack.
