'I'm good for my $80 billion': Satya Nadella's epic remark amid Elon Musk-Sam Altman spat over $500 billion AI project

Tech titan Elon Musk cast doubt on a $500 billion AI project announced by Donald Trump, saying the money promised for the investment actually wasn't there.

Billionaire Elon Musk reacted to a statement by Microsoft CEO Satya Nadella who was asked about the public spat between the Tesla chief and OpenAI CEO Sam Altman over the $500 billion AI project announced by US President Donald Trump.

Elon Musk reacted to a comment by Satya Nadella on the Stargate project.

It began when Elon Musk cast doubt on the Stargate project announced by Trump, saying the money promised for the investment actually wasn't there.

“They don’t actually have the money,” Musk wrote on his social platform X. “SoftBank has well under $10B secured. I have that on good authority.”

Altman responded Wednesday to say Musk was “wrong, as you surely know” and inviting Musk to come visit the first site in Texas that is already under construction.

Meanwhile, in an interview on CNBC, Microsoft CEO Satya Nadella was asked about Musk questioning value of the investment in the Stargate project.

“I’m not particularly in the details on what they’re investing," Nadella said about Stargate.

When asked about Musk’s posts on X claiming the money was not there for the project, Nadella said, “Look, all I know is, I’m good for my $80 billion.”

Reacting to a clip of the Nadella interview, Elon Musk said on X, “On the other hand, Satya definitely does have the money.”

Nadella replied to Musk's post, stressing on the larger goal of the project: “And all this money is not about hyping AI, but is about building useful things for the real world,” the Indian-origin tech leader said.

The comments by Elon Musk on the Trump-backed project marked a rare instance of a split between the world's richest man and Trump.

Microsoft is a key investor in OpenAI which listed the Nadella-headed software giant as one of its key initial partners in the Stargate project.

What is the Stargate AI project?

In his first full day in the White House, Donald Trump announced a major investment to build infrastructure for artificial intelligence led by Japanese giant SoftBank and ChatGPT-maker OpenAI.

Trump said the venture, called Stargate, "will invest $500 billion, at least, in AI infrastructure in the United States."
