A plan to build a system of data centers for artificial intelligence has been revealed in a White House press conference, with Masayoshi Son, Sam Altman, and Larry Ellison joining Donald Trump to announce The Stargate Project. Their companies, Softbank, OpenAI, and Oracle (respectively), along with MGX are listed as “initial equity funders” for $500 billion in investments over the next four years, “building new AI infrastructure for OpenAI in the United States.”

According to a statement from OpenAI, “Arm, Microsoft, NVIDIA, Oracle, and OpenAI” are the initial tech partners, with a buildout “currently underway” starting in Texas as other sites across the country are evaluated. It also says that “Oracle, NVIDIA, and OpenAI will closely collaborate to build and operate this computing system.”

Separately, Microsoft announced an update to its partnership with OpenAI, saying that the key elements of their deal remain in place through 2030, covering “our access to OpenAI’s IP, our revenue sharing arrangements and our exclusivity on OpenAI’s APIs all continuing forward.”

In a press conference announcing the project, which has been rumored since early last year, Son and Altman spoke directly to Trump, insisting that the project only happened because of his election victory.
