CHGG vs DUOL: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CHGG and DUOL share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CHGG and DUOL exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.

Chegg, Inc. is an American education-technology company that built its business on subscription study services: homework and expert question-and-answer help, step-by-step textbook solutions, writing and citation tools, and textbook rental and access. For years it grew by charging students a monthly fee for on-demand academic help, and at its peak it was valued in the billions with millions of subscribers.

Duolingo runs the world's most-used language-learning platform, a freemium mobile app built around gamified daily lessons, streaks, and a large free tier that funnels users toward paid subscriptions. It makes money from consumer subscriptions (Super Duolingo and the premium Max tier, which layers in AI-powered features), plus advertising to free users, an English-proficiency test, and in-app purchases. Its economics are attractive for a consumer app: gross margins around 73%, low capital intensity, and strong free cash flow helped by subscription payments collected up front. In the first quarter of 2026 it reported about 56.5 million daily active users and roughly 137.8 million monthly active users, with paid subscribers near 12.5 million.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• CHGG drivers: Building AI into its own products; Deep cost cuts and restructuring.
• DUOL drivers: User growth and engagement scale; Subscription monetization and Max.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The central risk is secular, not cyclical: free generative-AI chatbots and AI-powered search may permanently reduce demand for paid homework-help subscriptions, meaning revenue and subscribers could keep falling regardless of execution. For DUOL, the central risk is that increasingly capable AI translation and tutoring tools reduce the perceived need to learn a language, weakening Duolingo's pricing power and demand over time.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CHGG if you believe its drivers more; DUOL if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CHGG and DUOL guides.

CHGG. These figures are qualitative and directional, not precise or current. Chegg's business is changing quickly amid AI disruption and repeated restructuring, so revenue, subscriber, cash, and profitability figures can move materially between quarters. Always check Chegg's latest filings and earnings releases for exact, up-to-date numbers before making any decision. This is educational information, not investment advice.

DUOL. Duolingo is profitable and cash-generative, with a trailing price-to-earnings ratio around the mid-teens but a forward multiple near 50, reflecting how much the growth-over-monetization pivot compresses near-term earnings. The shares traded around $130 in early July 2026, off their roughly $540 record set in May 2025, a decline of more than 75%. That gap between strong operating metrics and a deflated price captures the market's unresolved debate over AI's effect on the category.

Headline figures (approximate, Jul 2026): CHGG shows revenue (ttm, declining) Falling sharply, with recent quarterly net revenues down roughly by half year over year as academic-services demand erodes., subscribers (declining) Down substantially from peak; hundreds of thousands of subscribers lost since free AI chatbots gained adoption., profitability (pressured) Under pressure amid falling revenue and restructuring charges; the company leans on aggressive cost cuts to defend cash flow., market cap (small, collapsed) A fraction of its pandemic-era peak after the stock fell the vast majority from its highs; now a small-cap.; DUOL shows revenue (ttm) ~$1.1B, q1 2026 revenue ~$292M (+27% YoY), daily active users ~56.5M (+21% YoY), paid subscribers ~12.5M (+21% YoY).

CHGG and DUOL are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined CHGG and DUOL exposure against your real portfolio. It is not an investment adviser.
