Three of the richest men in the world, foreign dignitaries, tech and business executives, former presidents and an assortment of performers and other celebrities are on the guest list for President-elect Donald J. Trump’s inauguration on Monday, even as much of the midday ceremony has been moved indoors amid forecasts of extreme cold.

It is unclear what impact, if any, the relocation of Mr. Trump’s second swearing-in ceremony into the Capitol Rotunda will have on the seating arrangements. Unlike the outdoor venue, the Capitol Rotunda only seats about 600 people.

Four years ago, Mr. Trump skipped President Biden’s inauguration in a snub to his political rival. Every living former president is set to witness his return to power, but some prominent Democrats are opting out.

Here’s the list of those who are planning to attend the inauguration, and notable no-shows.

Going

Billionaires, businessmen and tech executives

Elon Musk, Mark Zuckerberg and Jeff Bezos, three of the world’s wealthiest men, were reported to be among the major tech executives who would sit in a position of honor on the dais at Mr. Trump’s inauguration — before the event was moved indoors. Tim Cook, the chief executive of Apple, and Shou Chew, the chief executive of the imperiled social media app TikTok, had also been invited to sit on the dais.

Seating for other high-dollar donors from the business world was already highly competitive even before the last-minute move indoors. Some offered donations to Mr. Trump’s inaugural committee as high as $1 million without receiving any access to the inauguration or accompanying receptions in return.

World leaders

China’s vice president, Han Zheng, will attend the inauguration on behalf of Xi Jinping, whom Mr. Trump had invited to the inauguration.

Unlike at the inaugurations of President Biden and former President Barack Obama, a number of other world leaders will be in attendance. Many of them share Mr. Trump’s ideology and policy preferences.

From Latin America, Javier Milei, the right-wing populist president of Argentina, is reportedly planning to make an appearance. Jair Bolsonaro, the former president of Brazil and another right-wing populist, had intended to attend, but his passport was previously seized by federal police in Brazil and his request to a Brazilian Supreme Court justice to make the trip was denied.

From Europe, Giorgia Meloni, the right-wing prime minister of Italy, affirmed that she planned to attend. The press secretary of Viktor Orban, the prime minister of Hungary who has a friendly rapport with Mr. Trump, told a Hungarian media outlet that the prime minister had received an invitation but would not be attending.

Three representatives from key U.S. allies in the Asia-Pacific region will also be attending: S. Jaishankar, the external affairs minister for India; Penny Wong, the foreign minister of Australia; and Takeshi Iwaya, the foreign minister of Japan.

Trump’s presidential predecessors

Mr. Obama, George W. Bush and Bill Clinton will all attend Mr. Trump’s inauguration — as they did his first inauguration, eight years ago. They will not, however, attend a traditional lunch with the president-elect on that day, according to NBC News.

Former Vice President Mike Pence is also planning to attend the inauguration, according to two people with knowledge of the planning. He received an invitation, as is the custom for all former presidents and vice presidents.

Celebrity invitees

Carrie Underwood will sing “America the Beautiful” at Mr. Trump’s inauguration, according to a program of events. Victor Willis, the last surviving founding member of the Village People — whose music Mr. Trump frequently plays at this political rallies — announced on Facebook on Monday that the group had accepted an invitation to participate in Mr. Trump’s inaugural activities.

NBC News also reported that several athletes and musicians would be in attendance: They include Antonio Brown, the football player; Mike Tyson, the boxer; Jorge Masvidal, the martial arts fighter; and Evander Kane, the hockey player. The musicians Anuel AA, Justin Quiles, Rod Wave, Kodak Black and Fivio Foreign will also attend, NBC said.

Not Going

Michelle Obama

Mr. Obama is scheduled to attend, but Michelle Obama, the former first lady, will not. A statement from Mrs. Obama’s office did not specify a reason for the scheduled absence but noted that she had not attended another event this month: She did not accompany her husband to the funeral of former President Jimmy Carter, which every other living former president and first lady attended.

Nancy Pelosi

Representative Nancy Pelosi, the former speaker of the House and a chief antagonist of Mr. Trump during his first term in office, will also skip the inauguration. Ms. Pelosi, 84, is still recovering from a hip replacement after falling while on an official trip to Luxembourg, but she has been attending votes in the House. A spokesman would not specify why she would not attend, but there is long-running acrimony between Mr. Trump and Ms. Pelosi.

A number of House Democrats are also skipping the inauguration

Democratic members of Congress who have announced or told reporters of their plans to skip the inauguration include: Representative Adam Smith of Washington, Representative Judy Chu of California, Representative Delia Ramirez of Illinois, Representative Donald S. Beyer Jr. of Virginia, Representative Steve Cohen of Tennessee, Representative Jasmine Crockett of Texas, Representative Ilhan Omar of Minnesota and Representative Veronica Escobar of Texas.

President-elect Donald J. Trump and his family on Friday started selling a cryptocurrency token featuring an image of Mr. Trump drawn from the July assassination attempt, a potentially lucrative new business that ethics experts assailed as a blatant effort to cash in on the office he is about to occupy again.

Disclosed just days before his second inauguration, the venture is the latest in a series of moves by Mr. Trump that blur the line between his government role and the continued effort by his family to profit from his power and global fame. It is yet another sign that the Trump family will be much less hesitant in this second term to bend or breach traditional ethical boundaries.

Mr. Trump himself announced the launch of his new business on Friday night on his social media platform, in between announcements about filling key federal government posts. He is calling the token $Trump, selling it with the slogan, “Join the Trump Community. This is History in the Making!”

The venture was organized by CIC Digital LLC, an affiliate of the Trump Organization, which already has been selling an array of other kinds of merchandise like Trump-branded sneakers, fragrances and even digital trading cards.

But this newest venture brings Mr. Trump and his family directly into the world of selling cryptocurrency, which is regulated by the Securities and Exchange Commission. Mr. Trump recently disclosed he intended to name a cryptocurrency advocate as S.E.C. chairman.

A disclosure on the website selling the tokens says that CIC Digital and its affiliates own 80 percent of the supply of the new Trump tokens that will be released gradually over the coming three years and that they will be paid “trading revenue” as the tokens are sold.

The move by Mr. Trump and his family was immediately condemned by ethics lawyers who said they could not recall a more explicit profiteering effort by an incoming president.

“It is literally cashing in on the presidency — creating a financial instrument so people can transfer money to the president’s family in connection with his office” said Adav Noti, executive director of Campaign Legal Center, a nonprofit ethics group. “It is beyond unprecedented.”

Eric Trump, who helps run Trump Organization business operations, said on Saturday that this offering was part of a new and growing business sector that the Trump family has entered.

“I am extremely proud of what we continue to accomplish in crypto,” Eric Trump said in a statement to The New York Times. “$Trump is currently the hottest digital meme on earth.” He added: “This is just the beginning.”

But even some in the cryptocurrency industry were quick to criticize the new token.

“Trump owning 80 percent and timing launch hours before inauguration is predatory and many will likely get hurt by it,” wrote Nick Tomaino, a crypto venture capitalist and former executive at Coinbase, one of the largest crypto trading platforms, in a social media posting on Saturday.

The president-elect and his three sons had, as of late last year, already lent their name to another cryptocurrency startup called World Liberty Financial, an arrangement that included a cut of token sales for the Trump family in exchange for helping promote the new brand.

But the members of the Trump family, with World Liberty Financial, were not actually owners of the platform or officers in the company.

There are other crypto currency coins in the marketplace based on Mr. Trump that are not directly affiliated with his family like the new Trump Meme. Typically, these so-called meme coins — which were born when coins were created as a joke inspired by an internet meme or cartoonish animal faces — are largely worthless and traded more like a hobby.

With this new venture, companies associated with Mr. Trump’s family have a direct financial stake in the value of the new tokens and in the volume of their sales, which quickly surged after going on the market.

“GetTrumpMemes.com is not political and has nothing to do with any political campaign or any political office or governmental agency,” the venture’s website says, adding, “Trump Memes are intended to function as an expression of support for, and engagement with, the ideals and beliefs embodied by the symbol ‘$TRUMP.’”

The legal disclosures say the tokens are not intended to be seen as “an investment opportunity, investment contract or security of any type.” But trading of them on cryptocurrency markets began immediately, driving up the value of each token from $7 to nearly $30 as of noon on Saturday.

This suggested that the so-called fully diluted value of all the tokens as of Saturday at noon was $30 billion, a number achieved less than a day after the token went on the market, according to CoinMarketCap, a site that tracks cryptocurrency trading.

Mr. Trump and his family are clear in the marketing of the new token that the image picked for the coin had been inspired by the July assassination attempt in Butler, Pa.

“President Trump faced death and came up fighting!” the website promoting the tokens says.

Cryptocurrency markets tend to be highly volatile, in part because tokens are not backed by any tangible assets. The website for Mr. Trump’s new venture includes an extensive collection of disclaimers limiting the ability of anyone buying the token to file a class-action lawsuit related to it and warning buyers that “Trump Memes may be extremely volatile, and price fluctuations in cryptocurrencies could impact the price.”

Mr. Trump has already made clear that he will be working to promote the cryptocurrency industry.

He has announced his intention to appoint regulators who will lift restrictions on the sale of new tokens and ties between cryptocurrency companies and other more traditional financial enterprises.

This stands in contrast to efforts by Biden-era regulators to tightly regulate the industry, out of a concern that a sudden crash in the value of cryptocurrency could potentially lead to a future financial crash.
