Microsoft and OpenAI defended the USD500bn Stargate AI infrastructure project after Elon Musk criticized its funding, claiming SoftBank secured less than USD10bn. Musk’s ongoing feud with OpenAI CEO Sam Altman and Microsoft escalated, with Altman calling Musk’s claims false. Stargate, unveiled by Trump, promises 100,000 jobs and aims to secure the US’s AI dominance, partly funded by SoftBank, Oracle, OpenAI, and Abu Dhabi’s MGX fund. Initial funding is expected to include equity and debt, with USD100bn ready for deployment. Investors like Nvidia and Oracle saw share price jumps, signalling market confidence in the project.
