OpenAI CEO Sam Altman's decision to join President Trump's "Stargate" AI initiative marks a stark reversal for the tech CEO, who previously was a vocal critic of Trump.

OpenAI Chief Executive Officer Sam Altman briefed US policymakers on the need to continue investing heavily in physical infrastructure to support future artificial intelligence development, days after the frenzy around Chinese upstart DeepSeek cast new doubt on AI spending.

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.

SoftBank is in talks to invest as much as $25bn into OpenAI, in a deal which would make it the ChatGPT maker’s biggest financial backer, as the pair partner on a massive new artificial intelligence infrastructure project.

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.

Three major business leaders—SoftBank Group CEO Masayoshi Son, OpenAI CEO Sam Altman and Oracle Corp. Chairman Larry Ellison—joined President Donald Trump on Tuesday afternoon at the White ...

OpenAI chief executive Sam Altman has welcomed the debut of DeepSeek’s R1 model and has promised to deliver better AI models. The Chinese artificial intelligence start-up that rocketed to global prominence has delivered an “impressive model, particularly around what they’re able to deliver for the price,” Altman wrote.

President Trump and Elon Musk aren’t an exclusive item. That point was clear this week when the president welcomed OpenAI Chief Executive Sam Altman to the White House on the second day of Trump 2.0—a visit that left “First Buddy" Musk publicly fuming.

Donald Trump and three top tech firms announced on Tuesday that they would create a new company called Stargate to grow artificial intelligence infrastructure in the U.S. The President also said the three companies will collaborate and invest $500 billion in the AI infrastructure project.

Altman said that a project like Stargate might not have been possible with "a different president."
