Rosen Law Firm has filed a class action lawsuit on behalf of Duolingo investors who purchased Class A common stock between May 2, 2025 and February 26, 2026. The lawsuit alleges that Duolingo made materially false statements regarding user growth, failed to disclose that increased monetization efforts and ad friction were negatively impacting daily active users, and that AI-generated content was degrading product quality. Investors must move the court by December 7, 2026 to serve as lead plaintiff.
