DUOL INVESTOR ALERT: Robbins Geller Rudman & Dowd LLP Files Class Action Lawsuit Against Duolingo, Inc. and Announces Opportunity for Investors with Substantial Losses to Lead the Duolingo Class Action Lawsuit

A class action lawsuit has been filed against Duolingo, Inc. alleging that the company made false statements about Daily Active User growth while deliberately adding friction through increased ads and subscription upsells. The lawsuit covers stock purchases between May 2, 2025 and February 26, 2026. Duolingo's stock declined significantly following revelations of slowing DAU growth (from 49% to 30%) and a strategic shift away from monetization, with stock falling 25%, 8.5%, and 14% on three separate disclosure dates.
