Bloomberg reported on June 24, 2026, that Anthropic accused Alibaba-linked operators associated with its Qwen AI lab of using thousands of fraudulent accounts to access Claude and target capabilities including software engineering and agentic reasoning; Alibaba ADSs subsequently fell $2.80 per share, according to the complaint notice.

Bernstein Liebhard says representation is offered on a contingency-fee basis, meaning shareholders pay no fees or expenses, and investors can participate without serving as lead plaintiff.
Multiple law firms are recruiting investors for a securities class action against Alibaba Group Holding Limited over alleged misrepresentations spanning June 26, 2025, through June 24, 2026. The lawsuit claims Alibaba concealed major risks: undisclosed ties to China's Ministry of Industry and Information Technology, its listing as a Chinese military company by the U.S. Department of Defense, and accusations that Alibaba-linked researchers improperly accessed Anthropic's AI models. Bernstein Liebhard says shareholders who purchased Alibaba securities during this period may qualify for damages.
Alibaba stock tumbled after each disclosure went public. On June 10, 2026, shares fell $4.69 — about 3.9% — following the Defense Department's military designation. Days later, Bloomberg reported Alibaba-linked operators used thousands of fake accounts to access Claude, Anthropic's AI assistant, triggering a $2.80 share drop. Investors must file for lead-plaintiff status by October 5, 2026, though they may participate without taking that role.
Pentagon Adds Alibaba to Military Company List
On June 8, 2026, the U.S. Department of Defense officially added Alibaba to its updated list of Chinese military companies. The designation carries serious implications: it signals U.S. concerns about the firm's ties to Beijing's defense apparatus. Alibaba stock immediately reacted. Within two trading days, the company's American Depositary Shares fell $4.69 per share, closing at $115.38 on June 10. The lawsuit claims Alibaba failed to warn investors about this risk beforehand.
Alibaba Researchers Accused of AI Model Theft
On June 24, 2026, Bloomberg reported a serious allegation: Anthropic accused Alibaba-linked operators tied to Qwen, Alibaba's AI lab, of running a coordinated attack. The scheme involved thousands of fraudulent accounts designed to infiltrate Claude, Anthropic's AI system. The attackers targeted sensitive capabilities including software engineering and "agentic reasoning" — AI's ability to plan and execute tasks independently. The lawsuit alleges these were not isolated incidents but part of ongoing "distillation attacks" meant to steal AI model secrets.
After the Anthropic accusation became public, Alibaba ADSs fell $2.80 per share according to the complaint notice. The lawsuit claims Alibaba deliberately hid the risks of conducting such attacks from shareholders. The company allegedly knew the practice was happening and concealed it — not merely failing to disclose a hypothetical danger, but covering up real, active theft attempts.
How Investors Can Join the Lawsuit
The proposed class action names Alibaba and several senior officers as defendants and alleges violations of the Securities Exchange Act of 1934. Bernstein Liebhard is representing shareholders on a contingency-fee basis — meaning investors pay zero fees or expenses upfront. Lawyers collect only if the case wins or settles. Anyone who bought Alibaba stock during the class period qualifies automatically as a potential member.
Shareholders have two options: sit out quietly as "absent class members," or fight for lead-plaintiff status and help direct the case. The deadline to request lead-plaintiff status is October 5, 2026. Lead plaintiffs face extra responsibility but gain a voice in settlement negotiations. Either way, all class members share in any recovery. No action is required to stay in the class — investors are automatically included if they meet the purchase criteria.
