Chinese artificial intelligence startup Moonshot AI unveiled Kimi K3, a new open-weight model it claims can rival leading offerings from OpenAI and Anthropic. The announcement sent shares of Nvidia and other major technology companies sharply lower.

Investors are increasingly worried that cheap, open Chinese AI models could quickly erode the technological edge long held by leading US AI firms. The concern fueled a broad sell-off in chip stocks, overshadowing expectations for semiconductor demand.

Analysts said Kimi K3's real-world performance has not yet been independently verified, but noted that its open-source nature could push down the global cost of AI development. Markets are now watching closely for how US companies respond.
