Duolingo's AI Surge Drives 0.97% Gain as $1.14 Billion Volume Ranks 74th in Market Activity

On August 6, 2025, Duolingo (DUOL) closed with a 0.97% gain, trading at $1.14 billion in volume, ranking 74th in market activity. The stock’s performance followed a strategic pivot toward AI-driven enhancements, which underpinned a raised 2025 revenue forecast. The company now projects $1.01–$1.02 billion in annual revenue, exceeding prior guidance of $987–$996 million and analyst estimates of $996.6 million. Second-quarter revenue reached $252.3 million, surpassing expectations of $240.7 million.

Duolingo’s AI-powered subscription tiers, including Super and Max, drove user engagement and monetization. Features like video-call conversation practice with chatbots and personalized error analysis expanded to additional languages, accelerating subscription growth. CFO Matt Skaruppa noted reduced AI tool costs and improved ad performance, which supported gross margin resilience despite expanded AI investments. The company also leveraged generative AI to accelerate course development, introducing 148 new programs in one year after 12 years to create its first 100 courses.

User metrics reinforced optimism, with 46.6 million daily active users and 10.3 million paid subscribers in Q1. Subscription bookings rose 44% year-over-year to $232.2 million, fueled by high-value plans. Strategic acquisitions, such as music-based gaming studio NextBeat, signaled diversification beyond language learning into areas like chess and math. CEO Luis von Ahn emphasized the platform’s shift toward “entertainment-grade learning,” aligning with long-term growth ambitions.
