Nvidia's market value plummeted by a staggering $592.7 billion, setting a new record for the largest single-day loss in US stock market history.

On January 27, local time, stocks with the theme of artificial intelligence were sold off in European and American stock markets. In the US market, the Nasdaq Composite Index fell 3.07%. Shares of Nvidia Corp., a leading US stock in the artificial intelligence theme, plunged nearly 17%, erasing $59.27 billion in market value, setting a record for the largest single-day loss in US stock market history. Shares of Broadcom Corp. fell 17%, Advanced Micro-fabrication Equipment Inc. (AMD) fell 6%, and Microsoft Corp. (MSFT.US) fell 2%. Moreover, derivatives in the field of artificial intelligence, such as power suppliers, were also severely hit. Shares of United Energy Corp. (LNT.US) in the US fell 21%, and Vistra (VST.US) fell 29%. US media analysis believes that this is mainly due to the impact of DeepSeek, a Chinese AI startup. It is reported that DeepSeek's artificial intelligence assistant has replaced OpenAI's ChatGPT to become the most downloaded free application in the US Apple App Store. It is reported that the model developed by DeepSeek performed better than OpenAI in multiple tests and cost less than $6 million. At the Nasdaq exchange, a reporter interviewed Michael P. McDermott, vice chairman of Nasdaq, on the spot. McDermott said he believed that DeepSeek would be an important part of the revolution in the field of artificial intelligence.
