Today's stock pick is on me (From Behind the Markets)

Against the odds, language education platform Duolingo Inc. (NASDAQ: DUOL) continues to successfully navigate the threat of AI, for the most part. Despite a sharp share price decline throughout much of 2025 and into 2026, the company has spent the better part of this year gradually but steadily improving its stock performance. Cumulatively, it is up an impressive 55% in the last six months.

This figure got a boost after the company reported overall strong results for Q3 2026 on Nov. 3, 2026, prompting a share price spike of about 31% the following morning. The firm posted robust user engagement metrics, a sure sign that its service remains popular even as AI threatens to revolutionize the ways that people might choose to learn a language. At the same time, though, Duolingo continues to navigate the challenge of monetizing that user base and the risks of potentially slowing its user growth as a result.

A Closer Look at Duolingo's Q3 2026 Earnings

One of the key achievements for Duolingo in Q3 was that it accelerated its active user base growth. Daily active users climbed by 29% year over year (YOY) to almost 65 million, up from 23% YOY growth in Q2 of this year. The growth wasn't concentrated in a single part of Duolingo's customer base, either, and represented increased engagement from eight of its 10 largest markets. Best of all, perhaps, management expects the daily active user base to continue to grow at a similar pace through the end of the year.

It's helpful to see what specifically may be driving that user growth. Duolingo attributes much of this acceleration to product improvements, leading to stronger retention. Gaming partnerships have also appealed to a broader base of users, although these tend to be a bit more sporadic and are not likely a predictable and steady source of user growth.

With a growing user base, investors might rightly expect that Duolingo's revenue would also climb, and indeed the company has boosted its full-year sales guidance to $1.22 billion. On the other hand, profitability through the end of the year is likely to take a hit after the company missed on earnings per share (EPS) estimates by about three cents in Q3. Higher operating expenses are a major factor, but investment costs and employee bonuses are also impacting profits.

The User/Monetization Trade-Off Pressures Revenue

Despite the increase in projected revenue, YOY sales growth of approximately 14% for Q3 may leave some investors hoping for more. Bookings also climbed by 12%, a modest but not outstanding showing. At the same time, adjusted EBITDA margin slipped to 25.5% from 29.5% for the quarter.

All of these figures may reflect management's choice in the past to prioritize user growth over near-term monetization. This pivot may have prompted the major sell-off in DUOL shares that took place in 2025. Still, for other companies that may have opted for monetization over user growth, the outlook is not necessarily brighter.

For Duolingo, the trade-off between user growth and monetization may be worthwhile if it can accelerate its paid subscriber base fast enough. Paid subscribers climbed by 14% YOY to 13.1 million for the last quarter. While noteworthy, this growth rate is only half the rate of overall daily active user expansion, suggesting that there may still be opportunities to entice more paid subscribers than Duolingo has been able to achieve so far. The same can be said of bookings, which saw growth lag behind overall user base gains by an even wider margin.

That said, the company is finding ways to expand monetization. It is moving its video call feature—an AI-based tool that allows users to have real-time conversations to practice their language skills—from the top-tier Max plan to the Super plan as part of a broader move to move Max subscribers to Super at the same price. This suggests that Duolingo may be lumping AI features in with non-AI features at no (or minimal) added cost to the user.

In order for Duolingo to convert user growth to revenue, it will be essential for the company to boost its paid subscriber rates. Video calls being more broadly available may damage gross margins somewhat, so this is a signal that investors should keep an eye on as well.

Despite the many successes Duolingo reported in its earnings, as well as the significant post-earnings share price spike, Wall Street remains cautious about DUOL stock. According to MarketBeat's analyst ratings, 14 analysts rate the company Hold, eight Buy, and one Sell. Analysts are divided on whether DUOL's price will rise or fall. The consensus price target points to roughly 7% downside from recent trading levels, though several analysts raised their targets right after the latest earnings report.
