Trump AI investment with OpenAI, Oracle, Softbank

President Donald Trump announced on Tuesday the formation of a joint venture with OpenAI, Oracle AND Softbank invest billions of dollars artificial intelligence infrastructure in the United States.

The project, called Stargate, was presented at the conference White House by Trump, Softbank CEO Masayoshi Son, OpenAI CEO Sam Altman and Oracle co-founder Larry Ellison.

Management has pledged to invest an initial $100 billion and up to $500 billion over the next four years in the project, which will be established as a separate company.

“We want to keep it in this country,” Trump said of artificial intelligence, noting that China is a major competitor in the nascent industry.

Stargate's first joint venture will be to build data centers in Texas – work that is already underway, Ellison said in the Roosevelt Room.

OpenAI later stated in Post X that the project “will not only support the reindustrialization of the United States, but also provide a strategic capability to protect the national security of America and its allies.”

Softbank's son will become CEO of Stargate, and semiconductor company Arm, Microsoft, NVIDIA, Oracle and OpenAI will be “key initial technology partners,” OpenAI said in a post.

The son has already been announced a four-year, $100 billion investment in artificial intelligence in the United States in December, when he visited then-President-elect Trump's Mar-a-Lago resort.

Trump joked at the time that he was pressuring Son to increase his commitment to $200 billion.

“Now I'm back with $500 (billion),” Son joked at the White House on Tuesday.

In his remarks, Trump suggested the $500 billion figure would be separate from Son's previous promise.

“The $500 billion Stargate project is in addition to a separate commitment of $100 to $200 billion, as we know, from Mass,” Trump said.
