The investment brings together an alliance of tech giants. While SoftBank and OpenAI are lead partners—with SoftBank handling financials and OpenAI managing operations—Oracle and MGX have also joined as equity funders.

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.

SoftBank shares surged — on five times the previous day’s volume — on Wednesday after the Japanese investment group landed a starring role in an U.S. artificial intelligence infrastructure buildout package backed by President Donald Trump.

SoftBank, OpenAI, and Oracle are launching a $500 billion joint venture named Stargate to fund AI infrastructure in the U.S. The initiative, praised by President Trump, aims to deploy $100 billion immediately for projects like data centers and cancer research.

The president said it will be the largest AI infrastructure ever built and that it will help counter technology threats from China and other countries.

Donald Trump has announced the "Stargate Project." Backed by major tech companies, the project aims to boost AI infrastructure in the U.S.

Trump was joined by Oracle founder Larry Ellison, OpenAI CEO Sam Altman, and SoftBank CEO Masayoshi Son, who said the investment would start with $100 billion, plus a goal of $500 billion over the course of four years.

Shares in Japanese tech behemoth SoftBank Group soared more than eight percent on Wednesday after US President Donald Trump announced a major investment to build AI infrastructure.

SoftBank CEO Masayoshi Son's plan to invest billions in AI in the United States shows one way to handle the new Trump administration: go big and deal with the details later.
