Duolingo Raises 2025 Revenue Forecast as AI Features Boost User Growth

Duolingo (DUOL.O) raised its annual revenue forecast and surpassed second-quarter revenue estimates on Wednesday, driven by increased adoption of its AI-enhanced subscription services. The language-learning app’s shares climbed about 20% in after-hours trading.

Operating on a freemium model, Duolingo offers free basic lessons with premium tiers that provide advanced features through monthly or annual subscriptions. The company now expects 2025 revenue between $1.01 billion and $1.02 billion, surpassing analysts’ consensus of $996.6 million. Previously, the forecast ranged from $987 million to $996 million.

For the April-June quarter, revenue reached $252.3 million, beating analysts’ estimates of $240.7 million.

Duolingo’s two subscription tiers, Super and Max, include AI-powered tools like video-call conversation practice with chatbots, personalized error analysis, and improved feedback. Since launching its AI video-call feature on Android in January, the company has expanded it to more languages to enhance natural conversation practice and drive subscription growth.

The company’s gross margin exceeded expectations this quarter due to lower-than-anticipated AI costs and stronger ad performance, which, while a smaller part of the business, contributed positively to margins, CFO Matt Skaruppa said.

Duolingo uses generative AI to craft and personalize lessons across more than 100 languages. CEO Luis von Ahn noted that after 12 years to develop its first 100 courses, AI tools helped launch 148 new courses in about one year.

Looking ahead, Duolingo expects third-quarter revenue between $257 million and $261 million, exceeding analyst forecasts of $253 million, and projects adjusted core profit for 2025 in the range of $288.1 million to $295.5 million.
