Tech leaders should have a visible presence at Trump’s inauguration, with Jeff Bezos, Elon Musk, Mark Zuckerberg, Tim Cook, Shou Zi Chew, Sundar Pichai, and Sam Altman all reported to be present. Musk is also scheduled to speak at a pre-inauguration rally, and Zuckerberg will reportedly host a black-tie event on Inauguration Day.

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.

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.

Trump's inauguration drew several business and tech CEOs, including Jeff Bezos, Mark Zuckerberg, Elon Musk, Tim Cook, and TikTok's Shou Zi Chew.

The inauguration guestlist features unlikely names including MMA fighter Conor McGregor and influencer Jake Paul.

Tuesday marks President Donald Trump's first full day in office and similar to Inauguration Day, the president and his team are moving quickly to make change.

About 20,000 Trump supporters have gathered at Capital One Arena in Washington Monday afternoon, where Trump and Vice President JD Vance are expected to address the crowd later in the day. Trump is also expected to sign several executive actions at the area during his on-stage appearance.

Dana White, Logan and Jake Paul, Joe Rogan, Theo Von, and Javier Milei were among those spotted attending Trump's inauguration ceremony.

The inauguration of Donald Trump saw political leaders, industrial barons and far-right world leaders attend. Here's who was in the audience.

Four days before Donald Trump's second presidential inauguration, OpenAI CEO Sam Altman shared on X a threatening letter he had received from Sens. Elizabeth Warren (D–Mass.) and Michael Bennett (D–Col.). In the letter, the senators expressed dismay that the tech entrepreneur had donated $1 million to Trump's inaugural fund.

With Trump now taking the oath of office inside the U.S. Capitol Rotunda, only a few hundred people will be able to see the ceremony in person.

Such announcements aren’t without political risks, as OpenAI learned when Trump adviser Elon Musk criticized the deal on the social network he owns.
