Elon Musk and OpenAI CEO Sam Altman are fighting on X about Stargate, the infrastructure project to build data centers for OpenAI in the U.S.

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

The Stargate project has big implications for U.S. AI leadership, but also for who's winning the new president's ear.

Trump announced a $500 billion joint venture between OpenAI, Softbank, MGX and Oracle to build new datacenters to power the next wave of AI.

Under the Trump administration, OpenAI and other members of the tech sector are making a push to establish AI dominance in the U.S.

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.
