DeepSeek just shook up the artificial intelligence (AI) world in the biggest way since OpenAI launched ChatGPT in late 2022. The Chinese company's new R1 large language model (LLM) reportedly matches or beats OpenAI's o1 model on some benchmarks.

In a matter of days, DeepSeek proved to be so popular as to climb to the top of Apple's App Store, surpassing OpenAI's ChatGPT as the most downloaded app. But for owners of Nvidia stock, and stock traders in general, DeepSeek is on track of becoming a black swan — an unexpected event with extreme consequences.
