When the AI boom took hold, few companies looked more vulnerable than Duolingo Inc. (NASDAQ: DUOL). If a chatbot could teach you a language for free, so the thinking went, why bother with a dedicated app at all?
That fear sent the stock down more than 80% in less than a year, but since bottoming out last April, shares of the language-learning app have been rallying hard. With the stock having gained about 70% through the end of last week, this week’s jump came thanks to a fresh analyst upgrade.
Evercore’s Mark Mahaney has turned bullish, saying the threat from ChatGPT and its peers has been wildly overstated. Alongside a fresh Outperform rating, he raised his price target to $210, indicating more than 30% upside from current levels.
Maheney also reached for an interesting comparison. He likened Duolingo's setup to that of Netflix Inc. (NASDAQ: NFLX) in 2022, when the streaming giant's shares fell more than 75% before a wave of product improvements powered a spectacular recovery. As we head into the final few months of 2026, could Duolingo be setting up for a Netflix-style comeback of its own?
Why the AI Fear Was Overdone
The heart of the bullish case is that the market has fundamentally misjudged the AI threat. Rather than stealing Duolingo's users, tools like ChatGPT appear to coexist with the app, and often the same people use both. The evidence is telling. Evercore's research found that most language learners who use ChatGPT also use Duolingo, and crucially, they use the app just as intensively as Duolingo's most dedicated fans.
Far from cannibalizing the business, the AI-chatbot crowd treats ChatGPT as a casual supplement, reaching for it mostly for light, travel-related dabbling rather than serious study.
Given Duolingo’s stock had more than 80% of its value wiped out on the assumption that this wouldn’t be the case, that distinction matters enormously. It suggests the company’s committed, habit-forming core, the users who log in day after day to keep their streaks alive, remains firmly intact. But with shares still down 70% from last year’s all-time high, it feels like the market still hasn’t quite priced this in yet.
A Business in Good Health
Beyond the AI question, the underlying numbers paint a picture of a company in good health. User growth, for example, has been accelerating rather than fading, with daily active users recently hitting an all-time high. Just as important, those users are sticking around, with retention rates well above 80%. They’re also coming back, with a clever one-off campaign to win back lapsed learners bringing millions flooding back to the app.
That’s not exactly the kind of engagement momentum you’d expect from a product being disrupted by AI. Duolingo is also widening its appeal well beyond languages, pushing into subjects like math, music, and even chess, while using AI to slash the cost of premium features. One of the app's tools saw its cost per use collapse from around 30 cents to less than 1 cent, a neat illustration that, far from being replaced by AI, Duolingo is making it work in its favor.
Where the Bears Still See Risk
For all the renewed enthusiasm, the skeptics have not been entirely silenced, and their concerns deserve a fair hearing. The most pressing is the gap between Duolingo's booming user numbers and the slower pace at which it converts those users into paying subscribers. Strong engagement is one thing; turning it into hard revenue is quite another.
Then there are external risks, from the ever-present threat of new and more capable AI rivals to the regulatory complications of operating in China. This market holds the key to much of Duolingo’s planned growth. In addition, with such a sharp rebound in shares already, investors are right to question whether most of the easy gains have already been made.
Could History Repeat?
So, could Duolingo really deliver the next Netflix-style comeback? The parallel is appealing: a beaten-down favorite, written off too soon, staging a comeback on the back of relentless product innovation. If the comparison holds, today's price could look cheap in hindsight, just as Netflix's did after its own 700% recovery.
Yet caution is warranted. Netflix operated at a vastly greater scale, and the monetization questions hanging over Duolingo are real and unresolved. History, as ever, rarely repeats itself so cleanly, and a single upbeat analyst call doesn’t guarantee a repeat performance.
Still, the direction of travel is hard to ignore. Duolingo seems to have answered its biggest existential question, with strong evidence that AI is proving more friend than foe, and its engagement numbers keep climbing. For investors willing to look past the near-term doubts, this recovering favorite may be at the start of a triple-digit rally of its own.
