Musk torches $500B Stargate AI plan, Altman strikes back

OpenAI boss tell world's richest man money is there to fund infrastructure project

Updated The world has been treated to tech bros squabbling over Stargate, the alleged $500 billion artificial intelligence infrastructure project led by OpenAI, while the grown-ups look on.

The Stargate Project was made public on Tuesday during a White House briefing. The plan is to spend the money over the next four years building new AI infrastructure in the US for OpenAI to use to create new machine-learning models. An initial commitment of $100 billion is set to be deployed immediately.

The initial equity funders are SoftBank, OpenAI, Oracle, and MGX. OpenAI and SoftBank are leading the project, according to the ChatGPT super lab.

At least, that's the plan. Yesterday, Elon Musk, now part of the US administration via DOGE, upended a bucket of scorn on the announcement with a terse message on his social media mouthpiece, X. "SoftBank has well under $10B secured. I have that on good authority," he claimed.

Thus you had the US President Donald Trump heralding a project that his right-hand-man is within hours already trashing.

OpenAI boss Sam Altman responded to the Tesla tycoon, "wrong, as you surely know," before inviting Musk to a tour of the first Stargate site in Texas, which he said was already under construction.

Musk had earlier said, "They don't actually have the money," to which Altman retorted with the slightly bizarre response: "I genuinely respect your accomplishments and think you are the most inspiring entrepreneur of our time." Perhaps he used ChatGPT to come up with something to soothe the ego of a billionaire who is used to getting his own way.

Musk is certainly no friend of OpenAI these days, given the lawsuits he's filed against the organization, which he initially helped set up until a falling out, as it moves toward a for-profit future.

Elon also operates xAI, which provides the ChatGPT-rival Grok model to Twitter/X. In short, Musk is in competition with OpenAI, doesn't get on well at all with Altman, and couldn't wait to drag the biz and its Stargate plan, which had just been talked up by his boss, Trump.

Microsoft is listed by OpenAI as a key technology partner in its AI initiatives. When asked to comment on the furor during a CNBC interview, Microsoft CEO Satya Nadella wouldn't be drawn on Musk's comment or speculate on who might or might not have the funds in place for Stargate.

He said, "All I know is ... I'm good for my $80 billion."

Nadella was referring to Microsoft's planned capital expenditure to continue building out Azure, although he was responding to a question regarding Musk's suggestion that the Stargate money was not there.

Later, Musk commented, "On the other hand, Satya definitely does have the money," to which Nadella responded with a "tears of joy" emoji and the words, "And all this money is not about hyping AI, but is about building useful things for the real world!"

While the unfolding spat is unedifying – Musk's frustration with OpenAI is clearly sufficient to override his loyalty to President Trump in this instance – Nadella's words could be read a different way.

We asked Microsoft's Copilot how best to spend a billion dollars. Oddly, it didn't mention AI infrastructure at all. Instead, its top suggestion was philanthropy. ®

President Trump has signaled he's OK with squabbling billionaires as presumably it's all part of the show. Asked about Musk taking a pop at Stargate, the commander in chief said:

He hates one of the people. I’ve spoken to Elon; spoken to all of them, actually. The people in the deal are very, very smart people, but Elon, one of the people he happens to hate. But I have certain hatreds of people, too.

"He" being Musk, the "deal" being Stargate, and "one of the people" being OpenAI's Sam Altman.

Not to be outdone in the I'm-considerably-richer-than-you stakes, Saudi Arabia says it wants to put $600 billion into the United States over the next four years, though where exactly was not disclosed.
