US tech titans Elon Musk, Mark Zuckerberg and Jeff Bezos are taking a prominent place in the new Trump era, but another player from another era -- Oracle boss Larry Ellison -- is making a surprise return.

President Donald Trump talked up a joint venture investing up to $500 billion for infrastructure tied to AI by a new partnership formed by OpenAI, Oracle and SoftBank.

OpenAI CEO Sam Altman called Stargate, “the most important project for this era” and promised that all of the new investment his company was making would help cure diseases. Altman was actually prompted by Trump to talk about the medical advances that AI would supposedly figure out.

Masayoshi Son, the Japanese tycoon helming U.S. President Donald Trump's big new AI push, is the son of an immigrant pig farmer with a spectacular but also sketchy investment record. Trump's "friend Masa" was born in Japan in 1957 to ethnic Korean parents who scratched a living rearing chickens

Trump announced Tuesday that OpenAI, Softbank and Oracle would join forces to create Stargate, a new company investing $500 billion in AI infrastructure.

Last month, Trump announced with SoftBank's Son in Mar-a-Lago that SoftBank would invest $100 billion in US projects over the next four years, creating 100,000 jobs. Those investments will focus on infrastructure that supports AI, including data centers, energy generation, and chips, according to a source.

President Donald Trump said Tuesday he is open to Elon Musk buying TikTok, and floated a proposal that the United States jointly own half the company. “I would be, if he wanted to buy it, yes,” Trump told reporters at a White House event announcing a new AI infrastructure private sector partnership with tech leaders,

On Tuesday afternoon, President Donald Trump held a press conference to announce Stargate, a $500 billion artificial intelligence (AI) infrastructure project in the United States. He called it the "largest AI infrastructure project, by far, in history."

Musk's stance on the issue also contradicts Trump's announcement, who on Tuesday at a White House news conference along with Oracle Chief Technology Officer Larry Ellison, Softbank CEO Masayoshi Son and Open AI CEO Sam Altman,

Altman took to X to dispute Musk's characterisation on Wednesday, calling it wrong and suggesting Musk was upset because the pact could rival the billionaire's own AI efforts

The $500 billion Stargate project will be critical to "maintain American leadership in AI," one of the partners said in a statement.
