Kaplan Fox and Hagens Berman filed investor alerts this week urging shareholders who bought Alibaba Group Holding (BABA) stock to come forward. The claim follows a June 24 Bloomberg report that Anthropic told U.S. officials the Chinese e-commerce giant used thousands of accounts to extract Claude data through distillation, an alleged disclosure that Kaplan Fox says caused shares to fall.

What The Case Alleges And What It Means

Distillation is a process in which one company trains a smaller model to mimic a larger rival’s outputs using its responses as training data.

It threatens frontier models’ commercial value because training them costs enormous sums, if the company’s engineers extracted Claude outputs at scale, they could cheaply improve competing models without replicating Anthropic’s underlying research spend.

Anthropic’s original complaint described access through thousands of accounts, suggesting a coordinated scraping operation rather than isolated misuse.

The Hagens Berman alert says the complaint centers on undisclosed Chinese military ties alongside the AI claims, arguing public statements omitted material risk from both. The Kaplan Fox notice identifies the same June 24 report as the triggering disclosure event.

Bloomberg’s report was the first public account of Anthropic flagging the alleged access to U.S. officials, escalating a commercial dispute into a national-security framing.

This month’s alerts combine the distillation claim with the military-ties allegations, broadening the securities case beyond an AI dispute.

Investors are not suing over traditional financial fraud, but over whether the company adequately disclosed a technology dispute that could carry export-control or national-security exposure. For the valuation to make sense, the alleged undisclosed risks must be material to investors.

The October 5 deadline determines who leads the litigation, not whether it proceeds.

If the case survives early motions, a class-certification ruling could set precedent for how AI companies’ allegations translate into shareholder liability elsewhere.
