Oracle founder Larry Ellison said the Stargate project, a joint venture with OpenAI and Softbank, will help to fuel the development of a cancer vaccine.

Yes, that's the name of a 1994 Roland Emmerich movie. It's now a big infrastructure project to help power tech giants' foray into AI.

OpenAI CEO Sam Altman called Stargate, “the most important project for this era” and promised that all of the new investment his company was making would help cure diseases. Altman was actually prompted by Trump to talk about the medical advances that AI would supposedly figure out.

Stargate is supposed to spend $500 billion on AI infrastructure, President Trump said. But Elon Musk suggested that the venture had much less cash.
