Since then, Musk hasn’t hidden his anger with Altman and OpenAI. He’s currently suing the company over its decision to become a for-profit corporation, and he regularly trolls the company on X—the platform he bought for $44 billion back in 2022. All of which is why the past week has been hilarious.

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.

Altman and Musk were OpenAI’s founding co-chairs in 2015, but their relationship has devolved into name-calling and lawsuits.
