Investors who purchased Alibaba Group Holding Limited (NYSE: BABA) securities between June 26, 2025, and June 24, 2026, have until October 5, 2026, to seek appointment as lead plaintiff in a securities class action filed in the Southern District of New York. The case, Wistisen v. Alibaba Group Holding Limited, et al., No. 1:26-cv-06654, alleges that Alibaba and certain executives violated the Securities Exchange Act of 1934 by misrepresenting and failing to disclose that the company was directly or indirectly controlled by or affiliated with China’s Ministry of Industry and Information Technology, placing it within the National Defense Authorization Act definition of a Chinese military company, and that the risk of Alibaba carrying out distillation attacks on third-party AI models was ongoing rather than hypothetical. Partial corrective disclosures cited include the U.S. Department of Defense adding Alibaba to its Chinese military companies list on June 8, 2026, after which Alibaba ADSs fell $4.69, or 3.9%, over two sessions, and a June 24, 2026 Bloomberg report that Anthropic told U.S. officials Alibaba used thousands of fake accounts to access Claude models for unauthorized distillation, after which ADSs fell $4.73, or 4.7%, to close at $95.07 on June 25, 2026. Hagens Berman Sobol Shapiro LLP is urging affected investors to contact the firm regarding potential recoveries and lead-plaintiff rights.
