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.

The $500B Stargate Initiative, led by Trump, OpenAI, SoftBank, and Oracle, is set to revolutionize U.S. AI infrastructure.

Sam Altman, CEO of OpenAI, sparred Wednesday with Elon Musk over funding for a Trump-backed AI infrastructure project one day after he stood with the president in the White House to announce the project.

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.

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

At the White House on Tuesday, SoftBank CEO Masayoshi Son confidently predicted that “artificial superintelligence” will kick off America’s “golden age.” President Donald Trump beamed as Son, OpenAI’s Sam Altman and Oracle’s Larry Ellison announced a $500 billion investment in an American scheme to unlock the potential of super-powerful AI.

OpenAI and SoftBank have both committed $19 billion each to the Stargate venture worth $500 billion to build AI data centres in the U.S.

Some of the biggest names in technology have clashed after President Donald Trump unveiled his $500 billion private AI investment project. Earlier this week, Trump announced a joint venture with OpenAI,

Masayoshi Son founded SoftBank in 1981. It has invested millions in some of Silicon Valley's biggest tech companies.

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.
