The investor-rights firm said it is preparing a class action after Financial Times reported Anthropic accused Alibaba of using fake accounts to gain illicit access to Claude.
Rosen Law Firm said it is investigating potential securities claims involving Alibaba Group Holding Limited and is preparing a class action on behalf of shareholders who may have been affected by allegedly misleading business information. The inquiry follows a June 24, 2026 Financial Times article that said Anthropic accused Alibaba of obtaining illicit access to Claude by creating fake accounts to use the AI model, which the American company does not offer to Chinese groups. Alibaba American Depositary Shares, or ADS (U.S.-traded shares representing foreign stock), fell 2.7% on June 24, 2026 after that report, the firm said. Rosen said investors who purchased Alibaba securities may be able to seek compensation through a contingency fee arrangement and directed potential class members to contact the firm for information.
