Nvidia’s $465 bn plunge triggered by DeepSeek, largest in market history

Nvidia Corp.’s plunge, fueled by investor concern about Chinese artificial-intelligence startup DeepSeek, erased a record amount of stock-market value from the world’s largest company.

Nvidia shares tumbled as much as 13 per cent soon after the opening bell Monday, erasing about $465 billion from the company’s market capitalization. That eclipsed the previous record — a 9 per cent drop in September that wiped out about $279 billion in value — and was the biggest in US stock-market history.
