Duolingo shares tanked ~17% after forecasting slower earnings growth and narrower margins to fund a push for user growth (aiming for 100M DAUs). The company is pivoting to an "investment phase" to leverage AI for better teaching. In the current high-rate environment, investors punish companies sacrificing near-term margins for long-term user growth. The "AI tutor" narrative is currently seen as a cost center, not a profit center. AVOID. Sentiment has broken; the market requires proof of margin stability before re-rating. User growth accelerates faster than expected, forcing a short squeeze.
