DeepSeek's AI Breakthrough Triggers Unprecedented $1 Trillion US Stock Market Loss

In January 2025, Chinese startup DeepSeek unveiled its AI assistant, surpassing ChatGPT in the US App Store. 

DeepSeek's R1 model demonstrated advanced reasoning skills, developed cost-effectively using lower-performance Nvidia H800 chips. 

This innovation led to a 17% drop in Nvidia's stock, erasing $1 trillion from US tech stocks. 

DeepSeek's open-source approach and Test Time Scaling distinguish it from competitors like OpenAI. 

The company's success challenges US dominance in AI, highlighting China's rapid advancements in technology. 

DeepSeek's emergence marks a pivotal moment, prompting reassessment of strategies in the US tech industry.
