Elon Musk asked a judge to block OpenAI's attempt to transition from nonprofit to for-profit. It's not the first time he's feuded with CEO Sam Altman.

Sam Altman, the CEO of OpenAI, has announced a shift in his previously critical perspective on President Donald Trump. Newsweek has contacted OpenAI and the White House for comment via email.

Sam Altman's comments came amid a flurry of online exchanges between himself, Musk, and Microsoft over the $500 billion Stargate Project announced by Trump.

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.

The latest spat began after Altman joined Trump, SoftBank CEO Masayoshi Son, and Oracle Chairman Larry Ellison in a White House ceremony on Tuesday to announce the launch of Stargate, a $500 billion venture to advance the United States’ artificial intelligence infrastructure.

Musk’s criticisms have escalated into legal actions. In February, he filed a lawsuit against OpenAI, accusing it of breaching its nonprofit mandate. Although the lawsuit was withdrawn in June, Musk refiled it in August, further intensifying the conflict.

President Donald Trump spoke with OpenAI CEO Sam Altman by phone Friday, ahead of the AI infrastructure announcement, CNBC has learned.

OpenAI CEO Sam Altman announced on Thursday that the new o3-mini reasoning model will power ChatGPT chat sessions for free tier users.

Fortune reported that this announcement has put Sam Altman in the spotlight, much to the frustration of his former collaborator, Elon Musk. Musk, who has long been a major backer of Trump, was once close with Altman when they co-founded OpenAI in 2015. However, their relationship has soured over time, evolving into a fierce rivalry.

A new crack has appeared in the alliance between President Donald Trump and tech billionaire Elon Musk, who helped bankroll much of Trump's voter outreach operation and now heads up his "Department of Government Efficiency" task force.
