Nvidia says it will build up to $500bn of US AI infrastructure as chip tariff looms

Plan comes after Donald Trump reiterated import threats and chipmaker's CEO dined at US president's resort

The chip designer Nvidia has said it will build up to $500bn (378bn) worth of artificial intelligence infrastructure in the US over the next four years, in a sign of manufacturers investing in operations on American soil amid Donald Trump's tariffs.

The announcement comes after Trump reiterated threats on Sunday to impose imminent tariffs on the semiconductors that Nvidia makes mostly in Taiwan, and after the chipmaker's chief executive, Jensen Huang, dined at the president's Mar-a-Lago resort earlier this month.
