Full Analysis
Levi & Korsinsky, LLP has issued a press release regarding a securities fraud class action lawsuit filed against Duolingo, Inc. (NASDAQ:DUOL). The lawsuit alleges that the company made materially false or misleading statements concerning the sustainability of its daily active user (DAU) growth and the quality of its AI-generated content during the class period from May 2, 2025, to February 26, 2026. Plaintiffs contend that Duolingo raised its bookings guidance twice in 2025 while internal A/B testing data indicated that aggressive monetization strategies, including heavier ad loads and friction-inducing upsells, were weighing on user growth. The complaint asserts that management was aware of these issues but continued to project confidence, describing the growth as sustainable despite evidence to the contrary. The alleged misstatements contributed to a significant decline in Duolingo's stock price, which fell from $260.02 in November 2025 to $101.00 by late February 2026, representing a loss of over 61% for investors. The lawsuit specifically highlights the gap between management's public promises of 'growth at scale' and the reality of slowing DAU growth and a strategic shift away from monetization following disclosures in late 2025. Key allegations include that Duolingo deliberately introduced friction into the free user experience to boost revenue, a concession made by management in February 2026. The case was filed in the United States District Court for the Western District of Pennsylvania, with a lead plaintiff deadline set for December 7, 2026, and eligibility based on purchases during the specified class period.
