Tesla and SpaceX CEO’s comments came hours after the President’s inauguration Donald Trump On his first day in office, he unveiled the massive project at the White House.

“They literally have no money,” Musk wrote on his social platform X in response to an OpenAI post about a new project called Project Stargate.

“SoftBank has secured far less than $10B in guarantees. I have it on good authority,” Musk added in a subsequent post.

Musk is Trump’s biggest financial backer so far in the 2024 election and currently serves as chairman of the White House’s major government efficiency project.

On Wednesday morning, OpenAI CEO Sam Altman responded directly to Musk.

“I sincerely respect your achievements and consider you to be the most inspiring entrepreneur of our time,” Altman wrote on X.

However, Musk’s claims about SoftBank’s liquidity “are wrong, as you surely know,” Altman wrote in a follow-up post.

“I realize what’s good for the country isn’t always what’s best for your company, but in your new role, I hope you’ll put (American flag emoji) first,” he added .

OpenAI and Oracle did not immediately respond to CNBC’s request for comment on Musk’s claims. SoftBank declined to comment.

Musk’s posts about SoftBank are “completely baseless,” according to a person familiar with the AI ​​project who was asked to remain anonymous to discuss the situation.

The person added that there was “no doubt” that tensions between Musk and Altman were the catalyst for his Stargate posts.

Musk’s comments undermined Trump’s announcement Tuesday afternoon that Stargate would “invest at least $500 billion” and create “more than 100,000 American jobs almost immediately.”

“I think it’s going to be something very special. It’s going to lead to the biggest thing possible,” Trump said.

Trump spoke as he was flanked by Altman, Oracle co-founder Larry Ellison and SoftBank CEO Masayoshi Son.

Ellison said at that event that 10 data centers of 500,000 square feet each are already under construction in Abilene, Texas, with 10 more under construction.

Musk leads Trump’s new administration effectiveness advisory committee dogand has a tense relationship with Ultraman.

In March this year, Musk and his artificial intelligence startup xAI sued OpenAI, alleging breach of contract. Musk later dropped that lawsuit and in August Sue Ultraman in federal court.

Altman’s response to X was consistent with his previous public tone toward Musk.

Asked in December if he was worried about Musk’s influence in the White House, Altman said: “I could be wrong, but I have no doubt that Elon will do the right thing.”

OpenAI said in an announcement on Tuesday that Stargate “will begin deploying $100 billion immediately.”

The post stated that Masayoshi Son will serve as chairman of the new company, whose initial equity backers are SoftBank, OpenAI, Oracle and Emirates bank MGX.

News of the infrastructure plan sent Oracle shares up 7% on Tuesday.

OpenAI posts are also listed Microsoft Serves as one of Stargate’s key initial technology partners. The company said earlier in January that it planned to invest $80 billion in data centers to support artificial intelligence in the next fiscal year.

“I don’t know much about the details of their investment,” Microsoft CEO Satya Nadella said Wednesday when asked about Stargate on CNBC’s “Squawk Box.”

Asked about Musk’s post questioning Stargate’s funding, Nadella responded: “Look, all I know is I’m happy with my $80 billion.”
