Investors Invited to Lead Securities Fraud Class Action Against Duolingo, Inc.

Rosen Law Firm is soliciting investors who acquired Class A common stock in Duolingo, Inc. between May 2, 2025, and February 26, 2026, to participate in an ongoing securities class action lawsuit. Investors interested in acting as lead plaintiff must file their applications with the court no later than December 7, 2026.

The lawsuit alleges that Duolingo provided false or misleading information regarding its growth and user retention. Specifically, the complaint claims that the company intensified monetization efforts, such as increasing ad volume and subscription upsells, despite internal A/B testing data showing these tactics created friction that hindered daily active user (DAU) growth. Furthermore, plaintiffs argue that the company's reliance on rapidly generated AI content compromised product quality, impacting user experience and financial sustainability.

The class has not yet been certified. Investors currently retain the right to select their own legal representation or remain as absent class members.
