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.

Hours after returning to the White House, President Donald Trump made a symbolic mark on the future of artificial intelligence by repealing former President Joe Biden's guardrails for the fast-developing technology.

Both the Stargate announcement and the revocation of the AI safeguard Biden had put in place sparked widespread criticism from privacy and security experts.

SoftBank Group Corp., OpenAI, and Oracle Corp. are forming a $100 billion joint venture to fund artificial intelligence infrastructure, an effort unveiled with President Donald Trump aimed at speeding development of the emerging technology.

President Trump hosted executives from Softbank, OpenAI and Oracle at the White House Tuesday to announce “Stargate,” a $500BN private-sector plan to build new AI data centers.

President Donald Trump called Stargate, a new joint venture by OpenAI, Oracle, and SoftBank, "the largest AI infrastructure project in history."

The executive order directs the Department of Defense and the Department of Energy to lease federal sites to companies building AI infrastructure.

When Biden's AI Order was established, half a dozen US politicians applauded the measure alongside industry executives like Microsoft President Brad Smith, who called it a "critical step forward in the governance of AI technology" (In October, Microsoft founder Bill Gates quietly supported Kamala Harris for president with a $50 million donation).
