Robbins Geller sets Oct. 5 lead-plaintiff deadline in Alibaba securities case
Robbins Geller says investors in Alibaba securities have until Oct. 5, 2026, to seek lead-plaintiff appointment in a federal class action alleging misleading statements about military-company affiliation and AI conduct.
Robbins Geller Rudman & Dowd LLP said Tuesday that investors who bought or acquired Alibaba Group Holding Limited securities between June 26, 2025, and June 24, 2026, can seek appointment as lead plaintiff in a federal securities class action by Monday, Oct. 5, 2026.
The case, Wistisen v. Alibaba Group Holding Limited, No. 26-cv-06654, is pending in the U.S. District Court for the Southern District of New York. The firm said the suit alleges Alibaba and its chief executive officer violated the Securities Exchange Act of 1934.
Robbins Geller said lead-plaintiff applications can affect who directs a securities class action on behalf of investors. The firm said investors do not need to serve as lead plaintiff to share in any potential recovery.
According to the announcement, the complaint alleges that Alibaba and its executives made false or misleading statements, or omitted material facts, during the class period. The claims center on two issues: whether Alibaba was directly or indirectly controlled by or affiliated with the Chinese Ministry of Industry and Information Technology under the National Defense Authorization Act, and whether the risk that Alibaba would carry out distillation attacks against third-party AI models was ongoing rather than hypothetical or inadvertent.
The announcement said one market-moving event came on June 8, 2026, when the U.S. Department of Defense allegedly updated a list of Chinese military companies to include Alibaba. Robbins Geller said the complaint claims Alibaba American depositary shares declined nearly 4% on that news.
The firm also pointed to a June 24, 2026 Bloomberg article titled “Anthropic Accuses Alibaba of ‘Illicitly’ Accessing AI Models.” The announcement said the article described allegations that operators linked to Alibaba’s Qwen AI lab targeted Claude’s software engineering and agentic reasoning capabilities, and that Alibaba and other Chinese labs were using results from leading U.S. models to build rival chatbots through adversarial distillation. Robbins Geller said Alibaba ADSs fell 2.7% on June 24 and a further 4.7% on June 25, according to the complaint.
Robbins Geller said investors can contact attorneys Ken Dolitsky or Michael Albert by phone or email for more information on the lead-plaintiff process. The firm also included background material stating that it ranked No. 1 in the most recent ISS Securities Class Action Services Top 50 Report, recovered more than $916 million for investors in 2025, and recovered $8.4 billion over five years.
The Oct. 5 deadline is next. After that date, the court can consider lead-plaintiff applications in the Alibaba case.
