Nvidia was falling early Friday as politicians and Big Tech firms comment on the effects of Chinese firm DeepSeek’s apparently low-cost AI.

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.

Chinese state-linked social media accounts amplified narratives celebrating the launch of Chinese startup DeepSeek's AI models last week, days before the news tanked U.S. tech stocks, according to online analysis firm Graphika.

The little-known artificial intelligence firm has emphasized research, even as it emerged as the brainchild of a hedge fund.
