Duolingo Reports Q3 2026 Growth Acceleration Driven by AI Optimizations and User Retention
Duolingo (DUOL) reported strong third-quarter results characterized by a reacceleration in user growth, with Daily Active Users (DAU) increasing 29% year-over-year. This momentum was driven by improved product retention and the successful integration of AI-driven development tools, which allowed for a 90% increase in monthly A/B testing volume. The company also noted significant cost efficiencies in its video call features, with inference costs dropping from $0.30 to under $0.01 per call due to a transition to open-weight AI models. Looking ahead, Duolingo provided optimistic guidance for the fourth quarter, projecting revenue growth of 14% and bookings growth of 13%. While management expects a slight sequential decline in adjusted EBITDA margin and gross margin due to continued investments in AI features, the long-term outlook remains robust. The company is focusing on expanding its learner reach toward a goal of 1 billion people while optimizing subscription tiers by phasing out lower-performing segments in favor of Super Duolingo.
