As regulators close in, Nvidia scrambles for a response

Nvidia rocketed to the top of the tech industry by providing the computer chips essential to building artificial intelligence. By the end of last year, it had more than a 90% share of those chips sold around the world.

That success has quickly brought government scrutiny. Authorities with the European Union, Britain and China asked the company for information about its sales of those important chips, allocation of supplies and investments in other companies, according to Nvidia’s financial filings.
