Nvidia shares fell less than 2% in premarket trading Monday. The stock is among the hottest on the market, surging nearly 200% this year as the AI boom has fueled demand for the company's chips. Its market value is more than $3 trillion, second only to Apple.

China's government retaliated last week by banning the sale of materials essential for manufacturing the chips, including germanium and gallium.
