Key Takeaways
DUOL topped 50M daily users in 2025, while surpassing $1B in bookings and $300M in adjusted EBITDA.
Duolingo expanded margins by 90 bps as Gen-AI-powered Max and its vast dataset helped launch 148 courses.
DUOL targets 20% DAU growth in 2026 and approved a $400M buyback while pursuing 100M daily users by 2028.
Duolingo (DUOL - Free Report) closed 2025 with solid momentum, exceeding the 50-million daily active user (DAU) thresholds, generating more than $1 billion in bookings and more than $300 million in adjusted EBITDA for the first time. In doing so, the company’s motive to leverage AI as a vital cog within its growth engine has become more pronounced.
In the fourth quarter of 2025, DUOL witnessed a 90-basis-point year-over-year expansion in the gross margin, fueled by high-tier subscriptions like Duolingo Max, which utilizes Gen-AI for immersive practice. Duolingo holds one of the world’s largest datasets, which enhances personalization and expands into verticals, including math, chess and music. It has allowed the company to spearhead the launch of 148 courses in a single year.
The company has strategically pivoted to user scale over profit maximization. The CEO, Luis von Ahn Arellano, remarked that the company expects 20% year-over-year growth in DAU throughout 2026. The primary objective is to focus on providing better teaching quality, which could clear the path to 100 million DAUs by 2028.
For 2026, the management expects revenues to grow 10-12%, a significant deceleration from the 39% year-over-year jump in 2025. On the same note, the adjusted EBITDA is expected to be 25% in 2026, a let-down from the 29.5% reported in 2025.
While this slowdown raises questions on the company’s ability to squeeze out full potential from AI and data, the $400-million share repurchase program underscores confidence in the long-term growth. The rising demand for quality digital learning requires Duolingo to utilize AI and its proprietary data to gain an edge in the ed-tech market, positioning it as a transformative leader.
