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 OpenAIs IP, our revenue sharing arrangements and our exclusivity on OpenAIs APIs all continuing forward. What is changing is that Microsoft says OpenAI has made a new, large Azure commitment that will continue to support all OpenAI products as well as training. However, their exclusive arrangement for new capacity is changing so that now Microsoft has a right of first refusal over OpenAI building new capacity.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.
