Chipmaker Nvidia has become the world’s first $5tn company.

The surge in its share price follows an announcement from CEO Jensen Huang that the firm will build seven supercomputers for the US Department of Energy. It has also secured an order for $500bn in chips. 

President Donald Trump said he will discuss potential Nvidia exports to China with President Xi.

The AI boom has also seen Apple and Microsoft close on $4tn valuations.
