Hagens Berman Sobol Shapiro LLP said investors who bought Alibaba Group Holding Limited securities between June 26, 2025, and June 24, 2026, have until Oct. 5, 2026, to seek appointment as lead plaintiff in a securities fraud class action. The suit, filed as Wistisen v. Alibaba Group Holding Limited, et al., No. 1:26-cv-06654 in the Southern District of New York, alleges Alibaba and certain executive officers violated the Securities Exchange Act of 1934 by making materially false or misleading statements and omitting adverse facts about the company’s regulatory exposure and business practices. The complaint points to two alleged corrective disclosures: the U.S. Department of Defense adding Alibaba to its list of Chinese military companies under the NDAA on June 8, 2026, and a Bloomberg report on June 24, 2026, that Anthropic told U.S. officials Alibaba used fake accounts to carry out unauthorized distillation attacks on Claude. Hagens Berman said Alibaba ADSs fell 3.9% over two trading sessions after the first disclosure and dropped 4.7% to $95.07 on June 25, 2026, after the second.
