Full Analysis
A securities fraud class action lawsuit has been filed against Duolingo, Inc. alleging that the company misled investors between May 2, 2025, and February 26, 2026. The complaint asserts that defendants made materially false statements regarding the sustainability of their business operations and prospects during this period. The lawsuit centers on a significant deterioration in Duolingo's performance metrics starting in late 2025. Following a Q3 2025 earnings report showing slowing daily active user (DAU) growth, the company pivoted strategy to prioritize user growth over monetization. Subsequent reports in January and February 2026 confirmed further slowdowns in DAU growth and revealed that the financial effects of this strategic shift would materially harm bookings, revenue, and adjusted EBITDA. The core allegations state that Duolingo failed to disclose that its aggressive monetization tactics, including increased ad volume and subscription upsells, were deliberately introducing user friction. Internal A/B testing reportedly demonstrated that these friction points negatively impacted DAU growth rates and product quality, yet the company continued to issue positive statements about its business momentum. The stock price fell sharply following each negative earnings disclosure, dropping 25.49% in November 2025, another 8.45% in January 2026 after a CFO resignation and weak metrics, and a further 14.01% in February 2026. Investors who purchased securities during the class period may seek to recover losses by filing motions for lead plaintiff status by December 7, 2026.
