Tesla Inc. CEO Elon Musk cast doubt Wednesday on the ambitious $500 billion Project Stargate, hours after its announcement, claiming lead investor SoftBank Group SFTBY -0.36% + Free Alerts SFTBF + Free Alerts has “well under $10B secured.”

U.S. President Donald Trump announced Stargate, a $500 billion AI infrastructure project that's expected to provide 100,000 jobs and boost the American economy, but Elon Musk believes the three companies leading the project don't have the funds.

SoftBank Group shares jumped after the company and ChatGPT-maker OpenAI announced plans to invest up to half a trillion dollars in artificial-intelligence infrastructure in the U.S. Shares rose 8.8% to 10,060 yen, or equivalent to $64.69, on Wednesday in Tokyo, after climbing as much as 9.2% earlier, to their highest level since July.

US President Donald Trump announced that OpenAI, SoftBank Group and Oracle will unveil Stargate and invest $500 billion over the next four years to help the United States stay ahead of China and other rivals in the global AI race.

President Donald Trump is talking up a joint venture investing up to $500 billion for infrastructure tied to artificial intelligence by a new partnership formed by OpenAI, Oracle and SoftBank.
