Duolingo Inc.'s 2025 annual net income has been reported, with the company reaching $1 billion in revenue and surpassing 50 million daily users. However, the company's stock has fallen significantly, with some reports indicating a 25% plunge and others stating a 70% decline over the past year. The stock's poor performance may be due to the company's prioritization of user growth over other factors, although the potential for a rebound in 2026 is being considered.
