The legal action, filed in the Southern District of New York, claims Alibaba executives violated the Securities Exchange Act of 1934 by failing to disclose critical operational risks. Plaintiffs allege the firm concealed its ties to China’s Ministry of Industry and Information Technology, which led to its designation as a Chinese military company under the National Defense Authorization Act. Furthermore, the complaint highlights accusations that Alibaba used thousands of fake accounts to access Anthropic’s Claude AI, conducting unauthorized distillation attacks to train its own proprietary models.

Market confidence faltered following two major disclosures. When the U.S. Department of Defense officially added Alibaba to its military company list on June 8, 2026, shares dropped nearly 4%. A subsequent report on June 24, 2026, detailing the alleged AI model theft, triggered a further 4.7% decline. Hagens Berman partner Reed Kathrein is spearheading the investigation into these practices, focusing on whether management intentionally obscured the company's true risk profile. Investors seeking lead plaintiff status must file by October 5, 2026.
