Language learning platform Duolingo (DUOL) saw its shares surge 7.4% to $112.81 in afternoon trading Thursday, as investors weighed strong first-quarter results against a more cautious bookings outlook. The stock's rebound trimmed some of the week's earlier losses, bringing the company's market capitalization to approximately $5.26 billion.
Q1 Results Top Expectations
Duolingo reported first-quarter revenue of $292.0 million, a 27% year-over-year increase, exceeding analyst expectations. Net income came in at $43.5 million, while total bookings reached $308.5 million, up 14% from the prior-year period. Daily active users grew 21% to 56.5 million, and paid subscribers also rose 21% to 12.5 million.
CEO Luis von Ahn highlighted progress on the company's strategic roadmap, noting that Duolingo has "made speaking a core part of the learning experience" as it leans further into voice-driven features. CFO Gillian Munson reported that the company ended the quarter with $1.1 billion in cash and cash equivalents.
Bookings Slowdown Raises Concerns
Despite the strong Q1 performance, investor attention quickly shifted to the company's guidance for the second quarter. Duolingo forecast second-quarter bookings of $283.5 million, representing just a 5.8% increase, a significant deceleration from the 14% growth in Q1. For the full year 2026, bookings are projected at $1.28 billion, up 10.5%.
This slowdown comes as Duolingo ramps up investment in artificial intelligence and content expansion. The company has told investors that 2026 will be a year of investment, focusing on user growth, upgraded speaking features, and AI-generated content, while dialing back emphasis on near-term monetization and conversion of free users to paid subscribers.
AI Investment at the Core
AI sits at the heart of Duolingo's strategy. The company reported publishing 20,500 course units in the first quarter, sharply higher than the 7,100 per quarter in 2025 and well ahead of 1,800 per quarter in 2024. The content now extends through CEFR B2, the upper-intermediate tier on Europe's language scale, across its top nine languages.
Von Ahn told analysts on the earnings call that AI had "fundamentally changed what's possible" for Duolingo. CFO Munson emphasized that "2026 is a key strategic investment year" and projected free cash flow will exceed $350 million this year.
Margin Pressure and Competitive Landscape
The investment comes at a cost to margins. Duolingo now expects gross margin to slip to roughly 69% by the fourth quarter, dragged lower as AI features roll out, compared with 73.0% in the first quarter. Jefferies maintained its Hold rating and $95 price target, noting that first-quarter gains gave way to a second-quarter bookings slowdown and heavier bets on a back-half recovery.
Competition remains intense. Duolingo's latest 10-Q filing flags the usual rivals—Babbel, Rosetta Stone, and Busuu—as well as emerging pressure from AI chatbots offering budget-friendly conversation practice. The company must also stay ahead of the curve in artificial intelligence and machine learning.
Investor Dilemma
The key question for investors is whether more engaged users will ultimately translate into higher bookings. Duolingo projects daily active user growth hovering near 20% this year. But with conversion into paid plans potentially slowing over the next few quarters, the market is debating the real value of that user surge.
The company has repurchased about $50.6 million worth of stock—approximately 514,000 shares—through May 1, under its $400 million buyback authorization announced in February. As of Thursday afternoon, Duolingo's stock was trading around $112.81, still below its recent highs, as investors digest the trade-off between near-term growth and long-term AI-driven expansion.
