Prediction: This Glorious Growth Stock Is Going to Soar in 2027

Duolingo stock has surged 83% from its 52-week low of $90.03 in April after management's strategy shift to prioritize user growth over monetization proved successful. The company reached a record 64.9 million daily active users in Q3 2026, up 29% year-over-year, while leveraging declining AI costs to expand free features. Trading at a P/S ratio of 6.8 (below its 14.9 historical average), the stock appears undervalued with potential to reach its previous peak of $540 if the company successfully converts its growing user base into paying subscribers.
