Nvidia to build up to $500bn of AI gear in US, a first

Nvidia Corp, the dominant player in chips for AI models, plans to produce as much as half a trillion dollars' worth of AI infrastructure in the US over the next four years through manufacturing partnerships.
Production of Nvidia's latest generation AI chip, known as Blackwell, has begun at Taiwan Semiconductor Manufacturing Co's new plant in Phoenix, the company said..
Nvidia also said the effort would mark the first time that AI supercomputers are produced in the US, a development that President Trump touted on Monday. He said Nvidia made the decision because of tariffs. "It's one of the biggest announcements you'll ever hear - because Nvidia, as you know, controls that almost the entire sector."
