Duolingo has been a wild ride.
The stock fell 84% from $544 in May 2025 to $88 in April 2026, amid fears that free AI chatbots would replace a language-learning app and a deliberate pause in monetisation. It has since rebounded to $148.
The latest quarter shows why that debate is not settled. Daily active users grew 23% YoY to 58.7 million, faster than the quarter before. However, bookings, the cash customers commit up front, grew only 8% YoY. The users are coming back. The money has not caught up yet.
In this deep dive, I look at what our Multi-model Signals say about DUOL, why user growth and bookings have split apart, what management guided for the rest of 2026, and whether today's valuation leaves room for upside after the crash and rebound.
