What happened
Shares of Chinese AI companies Z.AI and MiniMax Group declined in Hong Kong trading following a report concerning DeepSeek and Moonshot, according to The Business Times.
Z.AI's shares dropped by as much as 7.4%, while MiniMax Group's shares fell by as much as 6.3%.
Why it matters
The size of the intraday moves suggests investors are treating the reported probe as a material risk for Chinese AI listings, at least in the short term.
Because the source material does not specify the nature or scope of the reported probe, the market reaction appears to be driven by uncertainty as much as by confirmed details.

What to watch next
