Nvidia Corp. lost more than $500 billion as the US stock market plunged amid the investor concern over Chinese artificial intelligence (AI) startup DeepSeek

The S&P Index also plummeted as much as 2.3 per cent on Monday over Deep Seek. Major concerns have been voiced over the low-cost Chinese AI model threatening dominance in the current AI leaders' world.
The DeepSeek startup had last week launched a free AI assistance that it said uses less data at a fraction of the cost of incumbent services, taking over its US rival ChatGPT in Apple store downloads by Monday.

Owing the weight that Nvidia carries in major indexes, throughout the day the US market saw the shares value dropping and rippling through the rest of the market.
