The firm said Alibaba ADS fell 2.7% on June 24, 2026 after a Financial Times report said Anthropic accused the company of obtaining illicit access to Claude through fake accounts.
Rosen Law Firm said it is investigating potential securities claims on behalf of Alibaba Group Holding Limited shareholders over allegations that the company may have issued materially misleading business information. The notice centers on a June 24, 2026 Financial Times article titled "Anthropic accuses Alibaba of obtaining illicit access to Claude," which said Anthropic accused Alibaba of obtaining illicit access to Claude by creating fake accounts to reach the AI model, which the American company does not offer to Chinese groups. Rosen said Alibaba American Depositary Shares, or ADS, fell 2.7% on June 24, 2026 after the news, and said it is preparing a class action seeking recovery of investor losses on a contingency-fee basis.
