Jan 21 (Reuters) - President Donald Trump is due to

announce private sector investment of up to $500 billion of

artificial intelligence infrastructure on Tuesday, two sources

told Reuters.

OpenAI, SoftBank and Oracle plan a joint

venture called Stargate, and have committed $100 billion

initially and then up to $500 billion into Stargate over the

next four years, the sources said.

CBS first reported the expected announcement.

SoftBank CEO Masayoshi Son, OpenAI's Sam Altman and Oracle's

Larry Ellison are due at the White House on Tuesday, according

to the CBS report.

Oracle and SoftBank did not immediately respond to requests

for comment.

Oracle shares were up 6% on the reports. Nvidia ( NVDA ),

Arm Holdings and Dell shares also rose.

In March 2024, The Information, a technology news website,

reported OpenAI and Microsoft ( MSFT ) were working on plans for a $100

billion data center project that would include an artificial

intelligence supercomputer also called "Stargate" set to launch

in 2028. It was not immediately clear if the announcement was an

update to this previously reported venture.

Investment in AI has surged since OpenAI launched ChatGPT in

2022, as companies across sectors seek to integrate artificial

intelligence into their products and services. AI requires

enormous computing power, pushing demand for specialized data

centers that enable tech companies to link thousands of chips

together in clusters.
