Alibaba investors who purchased securities between June 26, 2025, and June 24, 2026, have until Oct. 5, 2026, to seek lead-plaintiff status in a securities fraud class action filed in the Southern District of New York. Hagens Berman Sobol Shapiro LLP alleges that Alibaba Group Holding Limited and certain executive officers violated the Securities Exchange Act of 1934 by failing to disclose alleged ties to China’s Ministry of Industry and Information Technology, or MIIT, and risks associated with alleged distillation attacks on third-party AI models. The case, Wistisen v. Alibaba Group Holding Limited, et al., No. 1:26-cv-06654, follows Alibaba’s addition to a U.S. Department of Defense list of Chinese military companies and a Bloomberg report that Anthropic alerted U.S. officials to alleged unauthorized access to its Claude models through thousands of fake accounts. The release says Alibaba ADSs fell $4.69, or 3.9%, over two trading sessions after the June 8 listing and $4.73, or 4.7%, to $95.07 on June 25 after the June 24 report. An earlier investor notice cited different price-move figures for the same disclosures, creating a discrepancy in reported market impacts. Investors do not need to seek lead-plaintiff status to participate in any potential recovery, and the complaint’s allegations have not been proven in court.
