Advertisers eye mass arbitration; Aptoide sues Google

Google is facing a new two-front antitrust fight as advertisers organize mass arbitration claims and Aptoide sues over Android app-store access. (searchengineland.com) (reuters.com) Search Engine Land reported on April 14 that advertisers are preparing arbitration demands worth billions of dollars, using Google’s own ad-contract dispute clauses to press claims outside court. Bloomberg reported that companies including USA Today owner Gannett and Advance Publications are among those exploring payouts tied to Google’s search and advertising businesses. (searchengineland.com) (bloomberg.com) Aptoide filed its suit on April 14 in federal court in San Francisco, accusing Google of monopolizing Android app distribution and billing and seeking an injunction plus treble damages under United States antitrust law. Reuters described Aptoide as a Portuguese company focused on mobile games that calls itself the world’s third-largest Android app store. (reuters.com) (pocketgamer.biz) The advertiser push follows two major court losses for Google. In August 2024, a federal judge in Washington found Google illegally maintained monopolies in online search and search-text advertising, and the Justice Department said a remedies ruling later barred exclusive distribution deals and ordered some data-sharing with rivals. (justice.gov) (whitecase.com) A second ruling arrived on April 17, 2025, when Judge Leonie Brinkema found Google liable for monopolizing the open-web display publisher ad server market and the ad exchange market, while rejecting the government’s claim on advertiser ad networks. The court also found Google unlawfully tied its publisher ad server and ad exchange together. (justice.gov) (coag.gov) Mass arbitration works by filing many individual claims at once instead of one class action, which can force a company to pay large upfront case fees even before the merits are decided. Search Engine Land said lawyers are pitching advertisers on recovering a share of Google ad spending after the monopoly findings. (searchengineland.com) (webpronews.com) The ad-tech case centered on the software stack that helps websites sell ad space and matches that inventory with buyers in split-second auctions. The Justice Department said publishers depended on Google tools such as DoubleClick for Publishers and Google AdX, and the court found Google preserved power in those markets through exclusionary conduct. (justice.gov) (coag.gov) Aptoide’s complaint targets a different part of Google’s business: the rules that govern how Android users install apps and how developers process payments. Reuters said Aptoide argues Google used technical warnings, contractual limits and billing controls to keep rival app stores from gaining scale. (reuters.com) (wsau.com) Google has denied wrongdoing in both areas. After the 2025 ad-tech ruling, Google said it won half the case and would appeal the rest, and in the Aptoide case Reuters reported Google said Android competes with Apple and that device makers and users can choose among app stores. (searchenginejournal.com) (reuters.com) Google has already agreed to Android changes in a separate fight with Epic Games, according to reports in November 2025, and the new Aptoide suit seeks to press further on the same competitive fault line. The next tests are whether advertisers actually file claims at scale and whether judges or arbitrators turn the monopoly findings into cash penalties and operating changes.
