Tech titan Elon Musk cast doubt on Wednesday on a US$500 billion AI project announced by US President Donald Trump, saying the money promised for the investment actually was not there.

The comments marked a rare instance of a split between the world’s richest man and Trump, with Musk playing a key role in the newly installed administration after spending US$270 million on the election campaign.

In his first full day in the White House, Trump on Tuesday 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 US$500 billion, at least, in AI infrastructure in the United States”.

But in a post on social media, Musk said the main investors “don’t actually have the money”.
