Alibaba Faces U.S. Securities Class Action With October 5 Lead Plaintiff Deadline

Securities class action filed over June 2025–June 2026 disclosures

Two plaintiffs' firms notified shareholders that a securities class action has been filed against Alibaba Group Holding Limited (NYSE: BABA), covering investors who purchased or otherwise acquired Alibaba securities between June 26, 2025 and June 24, 2026. Kaplan Fox & Kilsheimer LLP issued its reminder on September 22, 2026, and Schall, Brown & Schwartz LLP also announced the same action on September 22, 2026. The complaint alleges violations of §§10(b) and 20(a) of the Securities Exchange Act of 1934 and SEC Rule 10b-5, asserting that Alibaba's public statements during the class period were false and materially misleading.

Alleged catalysts: Pentagon list and Anthropic accusation

According to the complaint summarized by Kaplan Fox and reproduced by SBS Law, the U.S. Department of Defense released an updated list of identified Chinese military companies after market hours on June 8, 2026, and Alibaba was included on the list because of alleged direct or indirect control by, or affiliation with, the Chinese Ministry of Industry and Information Technology (MIIT). The complaint further alleges that, on June 24, 2026, Bloomberg published an article titled "Anthropic Accuses Alibaba of 'Illicitly' Accessing AI Models," reporting that Anthropic PBC accused Alibaba of a large-scale effort to "illicitly" access its Claude artificial intelligence model through thousands of fraudulent accounts. SBS Law framed the alleged distillation risk against a Western AI model as "an actual ongoing activity" rather than a hypothetical risk.

Share-price impact alleged in the complaint

Kaplan Fox stated that on this news Alibaba shares fell $7.53 per share, or 7.4%, over two trading days to close at $95.07 per share on June 25, 2026. Both Kaplan Fox and SBS Law framed the alleged decline as the market reaction that triggered investor damages and supported the false-and-misleading-statement allegations.

Lead plaintiff motion deadline and procedural posture

Kaplan Fox and SBS Law notified putative class members that any motion to serve as lead plaintiff must be filed no later than October 5, 2026. Both firms stressed that seeking lead-plaintiff status is not required to share in any potential recovery. SBS Law noted that the class has not yet been certified and that investors who take no action will remain absent class members. Kaplan Fox separately identified its offices in New York, Oakland, Los Angeles, Chicago, and New Jersey, and listed [email protected] and (646) 315-9003 as contact channels; SBS Law listed partners Brian Schall, Andrew Brown, and David Schwartz at 2049 Century Park East, Suite 2460, Los Angeles, CA 90067, phone 310-301-3335, and email [email protected].

Unresolved factual questions

The reporting consists of plaintiffs' counsel summaries of an unverified complaint; the ledger does not include any court filing number, a response from Alibaba or its counsel, or any independent confirmation that the cited June 8, 2026 Pentagon list or the June 24, 2026 Bloomberg article contained the specific characterizations the complaint attributes to them. The ledger also does not show whether the case has been formally docketed beyond the firms' announcements.
