Elon Musk has objected to a lack of reciprocity in the US-China tech relationship, a rare criticism from the billionaire on issues sensitive to Beijing after US president-elect Donald Trump prepared to offer a reprieve to TikTok on a ban in the US.

Elon Musk has cast doubt on Donald Trump’s $500 billion AI project by questioning whether it has enough financial backing. “They don’t actually have the money,” the MAGA billionaire wrote on X in a rare public dig at Trump just hours after the president made a big announcement about the privately funded initiative.

OpenAI CEO Sam Altman fact-checked Elon Musk on Wednesday after the Donald Trump adviser attacked the company for being broke. President Donald Trump and OpenAI announced the Stargate Project, a partnership with Microsoft and others in AI that includes a "$500 billion investment over the next four years in building new AI infrastructure.
