Duolingo, Inc. is choosing growth over cash—and Wall Street isn’t clapping

What happened (and why the stock feels so different now)

Duolingo, Inc. (DUOL) has spent the last few years doing the rare internet trick: turning “a thing everyone uses for free” into a subscription machine without totally killing the vibe.

But on February 26, 2026—when Duolingo reported full-year 2025 results and laid out its 2026 outlook—the company basically told investors: we’re intentionally easing off the monetization pedal for a while. The market heard “slower growth,” and the stock reacted like you’d expect.

This isn’t a story about a broken business. It’s a story about a business choosing what it wants to be when it grows up: a lean, highly profitable app… or the default learning platform for a much bigger slice of the world.

The 2025 scoreboard: Duolingo didn’t just win, it lapped people

In 2025, Duolingo posted revenue of $1.04 billion and said daily active users hit 52.7 million, up 30% year over year. Bookings were $1.16 billion (up 33%)—the kind of number that makes a “freemium” model look less like a hope and more like a system.

Profitability wasn’t theoretical either. Duolingo reported adjusted EBITDA of $305.9 million (a 29.5% margin) and free cash flow of $360.4 million for 2025. The balance sheet ended the year with $1.04 billion in cash and cash equivalents and no debt.

This is the part where most tech companies would say, “We’re going to protect margins,” quietly raise prices, and let the app become a little less fun.

Duolingo is doing the opposite.

The pivot: less friction, more people

For 2026, Duolingo guided to revenue growth of 15%–18% and bookings growth of 10%–12%. It also expects its adjusted EBITDA margin to land around 25%.

Translation: management is choosing to spend more (including on AI-related product work and marketing) and to reduce monetization friction, even if that means slower near-term growth and lower margins.

The “why” is straightforward: Duolingo believes the bigger prize is scale. The company has a stated goal of reaching 100 million daily active users by 2028. In the same breath, it acknowledged that previous monetization tactics—more ads, more upsells—may have hurt the user experience and slowed word-of-mouth growth.

If you’ve ever watched a beloved app get more aggressive with pop-ups and nags, you already understand the fear Duolingo is trying to get in front of.

A buyback, plus a reality check about modern tech economics

Duolingo also authorized up to a $400 million share repurchase program. That’s notable not because buybacks are inherently “good,” but because it signals the company thinks it can both invest heavily and still generate enough cash to be flexible.

At the same time, the company expects its fully diluted share count to increase in 2026 (driven by equity compensation). That’s not unusual in tech, but it’s a reminder that “free cash flow machine” and “stock-based comp” often coexist.

What to watch next (without turning this into a spreadsheet)

Over the next few quarters of 2026, the key question isn’t whether Duolingo can squeeze more dollars out of power users. It’s whether it can:

• Keep the product lovable at scale (so user growth re-accelerates)
• Expand into new subjects (like math, music, and chess) without diluting the core experience
• Use AI to improve learning outcomes, not just generate content faster

Duolingo is betting that a slightly less aggressive money grab now leads to a much bigger ecosystem later. Wall Street tends to dislike “trust me” years. But consumer internet winners are often built exactly this way: protect the vibe, earn the right to monetize later.
