Shares of major US technology companies, including Nvidia and SpaceX, declined in trading following the announcement of a new artificial intelligence language model from China.

The development signals an intensifying competitive landscape for US tech giants as Chinese firms accelerate their AI capabilities.

The new model was unveiled by Moonshot AI, a startup backed by Alibaba.

The release of the Kimi K3 model represents a significant step in China's push to develop domestic AI infrastructure and reduce reliance on US technology providers.

This move aligns with broader strategic efforts by Chinese entities to displace US firms like Nvidia, Anthropic, and OpenAI from their domestic AI supply chains.

The market reaction reflects growing investor concern over the competitive threat posed by Chinese AI advancements.
