Advertisers vs Google, Aptoide sues

Google is facing a two-front antitrust fight: advertisers are preparing mass arbitration claims that could seek billions, and app store rival Aptoide has sued in federal court. (searchengineland.com, usnews.com) Attorney Ashley Keller told Search Engine Land the first advertiser filings were expected this week, and he estimated search and display ad claims could top $218 billion based on economic analysis commissioned by his firm. Google said in a recent filing that it faces private damages claims tied to antitrust cases but cannot yet estimate losses and plans to fight them. (searchengineland.com) Those claims are being organized as mass arbitration, a process that sends hundreds or thousands of similar disputes into private arbitration at the same time instead of one class action in court. ClassAction.org says lawyers are signing up advertisers who bought Google display ads and notes antitrust law can allow triple damages if claims succeed. (classaction.org, searchengineland.com) The push follows two major court losses for Google. A federal judge ruled in August 2024 that Google illegally monopolized online search, and a separate federal judge ruled on April 17, 2025 that Google unlawfully maintained monopolies in key ad technology markets. (justice.gov, justice.gov) In the search case, the United States Department of Justice said the court later barred Google from maintaining exclusive distribution contracts for Google Search, Chrome, Google Assistant and the Gemini app, and ordered it to share some search index and user-interaction data with rivals. Google and the government both appealed. (justice.gov) Aptoide’s lawsuit targets a different part of Google’s business: how Android users get apps and how developers get paid. The Lisbon-based company says Google used control over app distribution and billing to shut out rival app stores, even though Aptoide says it had more than 200 million annual users by 2024 and about 436,000 apps in its catalog. (usnews.com) Aptoide filed the case on April 14, 2026 in San Francisco federal court and is seeking an injunction plus treble damages, which means tripling any proven losses under antitrust law. The company said it charges lower commissions to developers and lower costs to users, and argued Google’s conduct kept top developers and key services tied to Google Play. (usnews.com) That suit arrives months after Google agreed in November 2025 to Android and app store changes to settle the Epic Games antitrust case. In that dispute, a jury found in 2023 that Google had unlawfully stifled competition in app distribution. (usnews.com) Google has said it disagrees with the monopoly rulings and is appealing them, while the new advertiser claims and Aptoide’s complaint test whether those court losses turn into direct payouts and operating changes.
