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.

Though Altman said he likely wouldn’t agree with Trump on “everything,” the OpenAI CEO said he believes “he will be incredible for the country in many ways.”
