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.

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

Trump Administration announced Stargate AI infrastructure joint venture, investing $500 billion over 4 years. SoftBank, Oracle, OpenAI, and Abu Dhabi's MGX involved.

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,

President Donald Trump said he is in favor of Elon Musk or Larry Ellison buying TikTok as he offered his latest thinking on what a deal might look like to save the US operations of the social media platform.

The new president needs the tech industry more than it needs him.

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

Trump unveiled the Stargate project, set up by Oracle, OpenAI and SoftBank, to build giant data centers for the next generation of AI. The project will invest $100 billion immediately, rising to $500 billion by 2029.
