International leaders will be present at Trump’s inauguration for the first time ever in American history.

President-elect Donald Trump’s second inauguration will have an attendee list that includes some of the wealthiest individuals in the world, prominent American politicians, international leaders, and celebrities who support Trump.

Due to the ceremony taking place in the U.S. Capitol Rotunda, only a limited number of individuals will be able to witness the event live. It remains uncertain which notable figures will be present, but here are the key individuals expected to be at the inauguration activities and galas.

President Joe Biden and Vice President Kamala Harris will be present at the inauguration, continuing the tradition of former presidential candidates joining the newly elected leaders on stage. The only recent exception to this custom was Donald Trump, who did not attend his successor’s inauguration four years ago.

Former Presidents Barack Obama, Bill Clinton and George W. Bush will also be in attendance. It’s set to be the first presidential inauguration featuring all of the living men who also held that office since President Obama’s first inauguration in 2009. 

Members of Congress will be among those allowed in the Capitol Rotunda to view the ceremony. 

For the first time in U.S. history, a president-elect will welcome foreign leaders for one of the most American political traditions — the peaceful transfer of power.

Argentine President Javier Milei and Italian Premier Giorgia Meloni are expected to be in Washington, but Chinese President Xi Jinping is sending his vice president as his representative. No heads of state have previously made an official visit to the U.S. for the inauguration.

Georgia President Salome Zourabichvili, Ecuadorean President Daniel Noboa and Paraguayan President Santiago Peña say they also will attend while French President Emmanuel Macron announced he won’t be there. 

The world’s three richest men were poised to sit on the dais as Trump is sworn in for a second term: Elon Musk, Amazon founder Jeff Bezos and Meta CEO Mark Zuckerberg. 

The three men are worth nearly $1 trillion combined and will be joined at the inauguration by the chief executive officers of OpenAI and the social media platform TikTok. Meta, Amazon and OpenAI CEO Sam Altman donated $1 million to Trump’s inauguration fund.

Other tech executives who’ll reportedly be in attendance are Sundar Pichai, the CEO of Google; Tim Cook, the CEO of Apple; and Dara Khosrowshahi, the CEO of Uber.

According to TMZ, other confirmed celebrity guests on the Trump inauguration list include Logan and Jake Paul, podcaster Theo Von, UFC founder Dana White, Amber Rose, Caitlyn Jenner, New York Jets running back Bryce Hall and Megyn Kelly. 

There’s also a handful of celebrities who’ll be performing at Trump’s inauguration, his weekend rally and inaugural balls. Country singer Carrie Underwood will perform “America the Beautiful” at the inauguration. 

The lineup of performers for the inaugural balls include Rascal Flatts, Gavin DeGraw, Jason Aldean, The Village People and Nelly. Rapper Snoop Dogg performed at a pre-inaugural “Crypto Ball” on Friday night. 

Former House Speaker Nancy Pelosi and former first lady Michelle Obama are among those planning to skip the inauguration events. Neither of their offices offered explanations for their absences. Michelle Obama also missed former president Jimmy Carter’s state funeral in Washington this month. 

While dozens of Democratic members of Congress boycotted Trump’s inauguration in 2017, according to the Washington Post only 20 Democrats in Congress have confirmed they won’t be attending Monday’s swearing-in.
