Capital World Investors reports beneficial ownership of 2,343,620 shares of Duolingo common stock, representing 6.0% of the 39,260,633 shares the filer believes are outstanding. The filing discloses sole voting power over 2,335,112 shares and sole dispositive power over 2,343,620 shares, indicating CWI can independently vote and dispose of the shares it holds.
The statement is submitted on Schedule 13G by an entity classified as an investment adviser (IA) and includes a certification that the securities are held in the ordinary course of business and not to change or influence control of the issuer, consistent with a passive ownership stake.
Baillie Gifford & Co has filed a Schedule 13G revealing a 5.6 % beneficial stake in Duolingo, Inc. (DUOL) as of 30 June 2025. The Scottish investment adviser reports ownership of 2,198,891 ordinary shares, crossing the 5 % reporting threshold.
- Sole voting power: 2,018,176 shares
- Sole dispositive power: 2,198,891 shares

The shares are held on behalf of advisory clients and were acquired in the ordinary course of business. As a passive Rule 13d-1(b) filing, Baillie Gifford states no intent to influence control of the issuer.
Key take-aways for investors: the position underscores continuing institutional support for DUOL, but a block of this size could become a liquidity overhang should the firm trim its holdings.
