Class action lawsuit filed against Duolingo over alleged misleading user growth and AI content claims.

Robbins Geller Rudman & Dowd LLP has filed a class action lawsuit against Duolingo, accusing the company and some executives of misleading investors about user growth and product quality. The lawsuit covers purchases of Duolingo stock from May 2, 2025, to February 26, 2026, alleging that Duolingo hid the negative impact of increased ads, subscription upsells, and AI-generated content on daily active user (DAU) growth. Following disappointing financial results and executive departures, Duolingo's stock price dropped significantly. Investors who suffered losses during this period can seek to become lead plaintiffs by December 7, 2026.

As of Oct 08, 2026 07:03 WIB, Duolingo Inc (DUOL) is trading at USD 151.76 on Pluang, showing a positive 1-day change of 2.45%. The stock has a market capitalization of $6.93 billion and an enterprise value of $5.70 billion. Despite the recent class action lawsuit and past stock price drops mentioned in the news, current Pluang order activity heavily favors buying, with 96% of orders being buys.
