Predicted vs. what happened
What happened
Reached 23% of the predicted growth at its peak, without hitting the target.
The thesis — published December 26, 2025
Duolingo is a well-run education app that just reported 50 million daily users, up 36% compared to last year, and subscription sales up 46%. One valuation report says the stock looks cheap. The price has been pushed down a lot, which can cause quick rebounds, but the stock can swing wildly, so buy in steps rather than all at once.
Primary drivers
- Recent results: many more users and subscription growth supports buying dips
- Price was pushed too low and can snap back quickly over weeks
- Good public sentiment plus strong business makes a healthy rebound more likely
- Valuation debate could push price higher if shares stabilize
How it played out
DUOL: the target was never reached
Lyra published DUOL at 180.64 on 2025-12-26 with a short-term thesis for 30% growth. The thesis pointed to 50 million daily users, 36% user growth compared to last year, 46% subscription sales growth, a valuation report that said the stock looked cheap, and the chance of a quick rebound after a sharp pullback.
Inside the window, DUOL peaked at 192.92 on 2026-01-05, a 6.8% gain. It stayed below the 234.83 target and never reached it. By 2026-03-26, it ended at 98.11. The thesis only partially played out at first, then missed.
What happened during the window
On 2026-02-27, Barron's reported that Duolingo had posted Q4 results and said it would prioritize user growth over near-term revenue growth. The article said the stock fell after that report.
