UK court clears way for mass advertiser damages claim against Alphabet

A UK tribunal has approved a class action lawsuit representing thousands of advertisers against Alphabet and Google entities. The case, filed by Or Brook Class Representative Limited, accuses Google of leveraging control over mobile systems, app stores, search, and search advertising to maintain supracompetitive pricing while blocking competitors. The tribunal approved an opt-out proceeding structure after dismissing Google's objections regarding case funding and participation rules. Claimants seek compensation pegged at approximately 5 billion euros, equivalent to roughly 5.7 billion dollars, for allegedly inflated advertising costs.

1. UK Competition Appeal Tribunal certified the class action on an opt-out basis on August 5, 2026
2. Or Brook Class Representative Limited filed the suit on behalf of affected advertisers

6. Google mounted multiple challenges including arguments about claimant funding and opt-out structure; the tribunal dismissed each objection
