The creator of ChatGPT, OpenAI, is teaming up with another US tech giant, a Japanese investment firm and an Emirati sovereign wealth fund to build $500bn (£405bn) of artificial intelligence (AI) infrastructure in the United States.

The new company, called The Stargate Project, was announced at the White House by Trump who billed it “the largest AI infrastructure project by far in history.”

The venture, which began before Trump took office, announced $100bn of funding was being made available immediately, with the rest to come over four years, creating an estimated 100,000 jobs.

It is a partnership between OpenAI, Oracle, Japan’s Softbank and MGX, a tech investment arm of the United Arab Emirates government.
