Duolingo helps AI and user growth as profit outlook softens

• Duolingo (NasdaqGS:DUOL) has shifted its focus to user growth and broader access to its AI learning tools, prioritizing free trials over short-term monetization.
• The company is expanding features such as its AI tool Video Call with Lily and investing in new learning areas such as chess, math and music.
• The change in direction was announced along with a $400 million share repurchase program and strong user and booking milestones, but was followed by intense negative reaction from investors and several Wall Street downgrades.

For those who follow Duolingo, the timing of this change is important. Because it comes after a severe decline in stock prices. NasdaqGS:DUOL closed at $101.0 and has returned 10.6% over the past week, 29.3% over the past month, 42.8% year-to-date, and 67.6% over the past year. A value_score of 4 suggests that the market is already pricing in considerable caution.

Duolingo’s decision to lean into free AI tools and new learning categories creates a tradeoff between engagement today and monetization tomorrow. Investors may be interested to see how quickly these AI capabilities impact user activity, and whether the $400 million share buyback will impact the stock base during this period of uncertainty. The key question for you as an investor is how comfortable you are with a growth-first strategy when stock prices are already under long-term pressure.

Duolingo has two known risks. Find out which ones may affect your investment.

For you, the investor, this decision lies at the intersection of product strategy and financial timing. The reset does not come from financial weakness, as Duolingo just reported full-year 2025 revenue of approximately US$1 billion and net income of US$414.1 million. The problem is that management is now pushing more AI-powered tools into the free tier and spending more on marketing, leading to slower booking and revenue growth in 2026. That’s why we’ve seen a sharp reaction in stock prices and a series of downgrades, even though the latest quarter beat expectations.

How does this fit into Duolingo’s story?

• Expansion into chess, math, and music and expanded access to AI tools are consistent with the existing narrative that expanding learning ecosystems can support long-term user growth.
• At the same time, business plans for slower booking growth and pressure on profitability make it difficult to focus early on the monetization benefits of new structures and premium tiers.
• The decision to extend AI functionality to free users and introduce a USD 400 million buyback when applying for ESOP-related shelves may not be fully reflected in previous comments about how product investments and number of shares will change.

Risks and rewards investors should consider

• ⚠️ Management expects booking growth in 2026 to be significantly lower than in 2025, and analysts caution that they expect revenue to decline on average over the next few years.
• ⚠️ While large platforms like Google and Apple’s AI tools improve, the choice to reduce monetization friction could put pressure on Duolingo’s pricing power and user engagement if implementation is delayed.
• 🎁 Duolingo has more than 50 million daily active users and reports strong year-over-year growth in quarterly and full-year net income, giving it more room to invest in product and marketing.
• 🎁 Duolingo is trading at levels suggested by some models, well below internal fair value estimates, while revenue is expected to grow at a double-digit percentage, which some investors may see as an interesting setup.

Future points of interest

The key thing to track from here is whether daily active user growth stabilizes or accelerates as AI capabilities are extended to free and Super Duolingo users, and how quickly management can reintroduce monetization without reversing that progress. Pay close attention to changes in booking growth, adjusted EBITDA trends, and the pace of US$400 million repurchases. These will demonstrate how confidently Duolingo can fund user growth while managing dilution from stock-based compensation. You can also compare Duolingo’s user and revenue trends to other consumer learning and productivity apps like Coursera, Chegg, or language tools bundled in the larger ecosystem to understand how Duolingo’s competitive position is evolving.
