Z.AI is trading 4.6% lower at HK$611.50, with no clear company-specific catalyst identified for the October 2, 2026 decline.

  • Recent coverage mentions remediation for the ZCode user-trust controversy, which began before this session and does not establish the cause of the move.
  • A reliable report tied a separate September 23 selloff in Chinese AI shares to regulatory-probe concerns around DeepSeek and Moonshot; it does not explain this decline. Broad-market indices provided were flat, leaving no clear market-wide driver.
