Investors who suffered significant losses in Alibaba Group Holding Limited between June 2025 and June 2026 now have until October 5 to join a class action lawsuit. The filing, Wistisen v. Alibaba, targets the company’s alleged failure to disclose ties to the Chinese military and unauthorized AI model access.
The legal action, brought by Hagens Berman Sobol Shapiro LLP, centers on accusations that Alibaba executives misled shareholders regarding the company's relationship with the Chinese Ministry of Industry and Information Technology. The complaint asserts that the company failed to disclose its status as a Chinese military entity under the National Defense Authorization Act, a designation that carries significant regulatory weight.
Beyond military ties, the lawsuit highlights allegations of improper conduct in the artificial intelligence sector. Reports indicate that Alibaba utilized thousands of fraudulent accounts to access Anthropic’s Claude AI models. These "distillation" attacks, which the company allegedly framed as hypothetical, were used to train Alibaba’s own proprietary models without authorization.
These disclosures triggered sharp declines in Alibaba’s share price. Following the Department of Defense’s June 8, 2026, announcement regarding the company’s military status, shares dropped nearly 4%. A subsequent report on June 24 concerning the Anthropic AI breach caused a further 4.7% slide. Reed Kathrein, the Hagens Berman partner leading the investigation, stated the firm is examining whether these operational practices were intentionally concealed to manipulate the company's market risk profile. Investors interested in lead plaintiff status or those with non-public information are encouraged to contact the firm before the October deadline.
