Duolingo IncDAU growth accelerates to 23%, defying AI threat, with CEO guiding above 20% for rest of year.

Duolingo, Inc. (NASDAQ:DUOL) has seen its user engagement data challenge the narrative that free AI tutoring would make its paid language app obsolete, with daily active users growing 23% to 58.7 million in the second quarter of 2026. The stock, which had fallen more than 50% over the past 52 weeks, jumped about 7% after DA Davidson upgraded it to Buy with a target of $160 on August 18, 2026. CEO Luis von Ahn said DAU growth is likely to remain above 20% for the rest of the year, while paid subscribers rose 17% to 12.7 million. AI has flipped from a threat to a tailwind, as lower AI costs lifted gross margin to 72.6% and allowed Duolingo to expand its Video Call feature to Super subscribers. However, net income fell 26% year over year due to higher operating expenses, and short interest sits near 20.72% of shares, with 19 of 27 analysts still rating the stock Hold. The company trades at approximately 21.6 times forward earnings, and while DAU growth outpaces revenue growth, full-year revenue growth of about 16% is down from nearly 40% a year ago.
