Duolingo, Inc. (DUOL)

The panel's take

Verdict: WAIT · Conviction: MEDIUM · Last price: USD 117.96 (as of 2026-06-09)

Almost no one on the panel doubts the franchise — 56.5M daily users, ~73% gross margins, $360M of free cash flow, $1.1B net cash — and almost everyone wants the same thing before committing: proof that the deliberate 2026 "investment year" (bookings growth cut to ~10-12% to push AI features free and chase 100M users) is working. With a broken chart, the stock sitting above the analyst-target cluster, and the AI-tutor question unresolved, the panel converges on waiting for the next data point rather than acting at $118.

Key levels

Key support sits at the ~$108-110 capitulation low (heavy-volume, multi-year accumulation zone), then $90-95 and $78; key resistance runs from ~$155 up through the historical resistance bands at $200 and $300. The analyst consensus target spans roughly USD 85 to 270 with an average near USD 108 — notably, current price is already slightly above that average.

What legendary investors think

We ran Duolingo past a panel of six legendary investors' frameworks.

Where they agree — and where they clash

Common ground

• The business is high-quality and cash-rich: ~73% gross margin, ~$360M FCF (≈35% margin), $1.1B net cash, near-zero debt, 30%+ ROE.
• The ~78% crash was mostly a valuation reset plus a self-inflicted guidance cut (a deliberate choice to grow users over near-term monetization), not a collapse in the franchise.
• The next real proof point is Q2/Q3 2026 — whether DAU growth and bookings re-accelerate as the pivot intends.

The real debate

• Is AI a threat or a tailwind? Wood and Fisher argue Duolingo Max and an AI content engine make it an AI winner; Buffett and Burry argue a free ChatGPT/Gemini conversation structurally erodes the reason to pay.
• Is the bookings cut strategy or symptom? Management (and the bulls) call it a deliberate investment year; Burry reads decelerating bookings as the leading indicator that revenue follows lower in 2027.
• Price: the bulls see today's ~4.5x revenue as cheap for the quality; Damodaran, Buffett, and Burry want $70-80 for a genuine margin of safety — and note the stock now trades above the analyst-target average.

The question it comes down to: Is the 2026 bookings deceleration a temporary, deliberate pivot that re-accelerates in 2027 — or the leading edge of AI commoditizing paid language learning?

The numbers

Metric	Value
Price / Market cap	USD 117.96 / ~5.5B
P/E (TTM / fwd)	~35x (normalized) / ~42x
ROE	~37%
Operating margin	~15% GAAP (~29% adj. EBITDA)
Dividend yield	0% (no dividend)
Debt / equity	0.07
Free cash flow	USD 360M (FY2025, ~35% margin)

Figures as of FY2025 / Q1 2026; sourced from Duolingo IR/SEC filings, GuruFocus, StockAnalysis, Multiples.vc. Note: reported TTM GAAP P/E (~13-14x) is distorted by a one-time FY2025 tax benefit; the normalized figure is used here.

The bottom line

This is the unusual case where the disagreement over the business has a date on it. Duolingo is plainly a quality franchise — dominant brand, world-class margins, fortress balance sheet, a founder who just bought stock alongside his CFO — and its ~78% fall was driven largely by a guidance reset the company chose, layered on top of a genuine but unproven fear that free AI tutors erode the reason to pay. What separates the bulls from the bears is not whether the business is good but whether the 2026 bookings slowdown re-accelerates or keeps bleeding through to revenue in 2027 — and that question gets its first real answer at Q2/Q3 earnings. What would tip it bullish is DAU growth re-accelerating toward 25% with Duolingo Max penetration climbing; what would tip it bearish is bookings staying in the single digits or a credible free, habit-forming AI competitor taking share. Until the data arrives — and with the price sitting above where most analysts peg it — the case for and against hang on a proof point that hasn't printed yet.
