Sam Altman, CEO of OpenAI, sparred Wednesday with Elon Musk over funding for a Trump-backed AI infrastructure project one day after he stood with the president in the White House to announce the project.

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.

Elon Musk doesn’t miss an opportunity to take a dig at OpenAI — even when the news item in question is supposed to be favorable to President Trump. Just a few hours after yesterday’s White House presser on The Stargate Project wrapped up, Musk posted on X that “they don’t actually have the money.”
