Alibaba Faces Class-Action Lawsuit Over Alleged Fraudulent Practices

Alibaba Group Holding Limited, the Chinese multinational technology giant listed on the New York Stock Exchange under the ticker BABA, is facing a significant legal challenge. A class-action lawsuit has been filed against the company, alleging that it engaged in fraudulent practices and failed to disclose crucial information to investors. The lawsuit, titled Wistisen v. Alibaba Group Holding Limited, et al., No. 1:26-cv-06654, was filed in the Southern District of New York and accuses Alibaba and certain of its executive officers of violating the Securities Exchange Act of 1934.

The class period for the lawsuit spans from June 26, 2025, to June 24, 2026. Investors who purchased or acquired Alibaba securities within this timeframe and suffered significant financial losses are encouraged to contact Hagens Berman Sobol Shapiro LLP, a plaintiffs' rights complex litigation firm. The firm is urging investors to submit their losses now and to learn more about their legal options.

According to the complaint, Alibaba and its executive officers made false and misleading statements about the company's business, operations, and prospects. Specifically, the lawsuit alleges that Alibaba was directly or indirectly controlled by or affiliated with the Chinese Ministry of Industry and Information Technology (MIIT), and this information was not disclosed to the public. Additionally, the complaint states that the risk of Alibaba carrying out distillation attacks against third-party AI models was not a mere hypothetical or inadvertent, but ongoing.

The truth regarding Alibaba's regulatory exposure and alleged illicit business practices was revealed in a series of partial corrective disclosures. On June 8, 2026, the U.S. Department of Defense added Alibaba to its list of Chinese military companies under the National Defense Authorization Act (NDAA) due to its ties to the MIIT. This news caused Alibaba's American Depositary Shares (ADSs) to fall by $4.69 per share, or 3.9%, over two trading sessions. On June 24, 2026, Bloomberg reported that Anthropic alerted U.S. officials that Alibaba had fraudulently accessed Anthropic's Claude AI models via thousands of fake accounts to execute unauthorized "distillation" attacks to train its own models. This news caused Alibaba's ADSs to fall by $4.73 per share, or 4.7%, to close at $95.07 on June 25, 2026.

Hagens Berman's investigation suggests that Alibaba's public statements were materially false and/or misleading at all relevant times, leading to substantial financial losses for investors. The firm is urging investors who purchased or acquired Alibaba securities between June 26, 2025, and June 24, 2026, and suffered significant financial losses to submit their information to the firm by October 5, 2026, to ask the court to appoint them as lead plaintiff. Investors do not need to seek lead plaintiff status to share in any potential recovery.

The lawsuit highlights the importance of transparency and accountability in the technology sector, particularly for companies operating in the United States and China. As the legal proceedings continue, the outcome could have significant implications for Alibaba's stock price and its reputation in the global market.
