At a press conference capping his first full day back in the White House, Donald Trump stood beside three of the most influential executives in the world—Sam Altman of OpenAI, Larry Ellison of Oracle,

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.

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.

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.

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

Masayoshi Son of SoftBank, Sam Altman of OpenAI and Larry Ellison of Oracle joined Trump for the $500 billion announcement.

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.

We're learning more about a massive artificial intelligence infrastructure bill announced Tuesday by President Donald Trump.

Elon Musk and Sam Altman publicly dispute the feasibility of 'Stargate,' a $500 billion AI infrastructure project in the US. Musk claims the necessary capital isn't available, while Altman defends the project's viability.

President Trump and a host of tech leaders (Softbank's Masayoshi Son, OpenAI's Sam Altman, and Oracle's Larry Ellison) teamed up to announce "Stargate" on Tuesday, an AI mega-project that includes a $500 billion investment in AI infrastructure to build data centers in the U.

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