Google and Alphabet v. European Commission (Ad Tech Self-Preferencing, Case AT.40670)

On Appeal Regulatory / Competition Technology €2.95B

After a €2.95B EU fine for rigging its ad-tech stack in favor of its own exchange, Google is fighting annulment proceedings at the General Court while the Commission market-tests its proposed fixes against the threat of forced divestiture, and publisher damages claims are already following on in Amsterdam.

A Paris court (Tribunal des Activités Économiques) ordered Google to pay roughly €126M in follow-on ad-tech damages to Le Figaro, Les Echos-Le Parisien, Prisma Media and Dailymotion in a ruling issued around June 29-30, 2026, adding to the earlier M6 and L’Équipe awards. Ad-tech company Teads sued Google and Alphabet in the Southern District of New York on August 3, 2026, alleging rival exchanges lost about 6.88 trillion impressions to AdX between 2017 and 2023, a US follow-on to the E.D. Va. liability ruling that joins the European wave led by the Amsterdam publisher suit and the pending General Court annulment action.

On 5 September 2025, the European Commission fined Google €2.95B in Case AT.40670, finding that since 2014 it abused dominant positions in publisher ad servers and programmatic ad-buying tools in breach of Article 102 TFEU: its ad server DFP gave its own exchange AdX advance information on rivals’ best bids, and its buying tools Google Ads and DV360 steered demand to AdX. The decision ordered Google to end the self-preferencing and to propose remedies within 60 days, with the Commission stating its preliminary view that only a structural remedy, divesting part of the ad-tech stack, would resolve Google’s inherent conflicts of interest. The case is the mirror image of the parallel US litigation in the Eastern District of Virginia, where a federal court found Google illegally monopolized the same markets in April 2025 but, on September 2, 2026, rejected the government’s bid to force divestiture of AdX and ordered behavioral remedies instead.

Google proposed behavioural remedies on 14 November 2025, including publisher-set differential price floors and greater interoperability of its tools, which the Commission is now market-testing with hundreds of stakeholders while keeping the divestiture option open. Google’s annulment action against the decision and the fine, Case T-794/25, was published in the Official Journal on 12 January 2026, and the Commission released the provisional non-confidential decision that month. Private enforcement has begun: in June 2026 more than 20 European news publishers, funded by Prague-based LitFin, filed a €640M follow-on damages claim against Google in Amsterdam.
