President Donald Trump announced Tuesday a joint venture called Stargate, which will pump billions of dollars of private funding into artificial intelligence infrastructure in the United States.

President Trump dismissed Elon Musk's doubts about the $500 billion “Stargate” AI project, citing personal differences. OpenAI CEO Sam Altman defended the project and invited Musk to visit the construction site.

Shares of SoftBank Group Corp. jumped as much as 8.1% after US President Donald Trump announced a multi-billion dollar push by the Japanese company, OpenAI and Oracle Corp. to build AI infrastructure in the US.

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

The initiative announced by President Donald Trump will aim to "secure American leadership in AI" while also creating jobs and economic benefit.
