• Citadel CEO Ken Griffin's Stegosaurus fossil will be displayed at the American Museum of Natural History.
• Griffin purchased the fossil — dubbed Apex — for $44.6 million in July.
• The fossil is 150 million years old and nearly 80% complete.

Citadel CEO Ken Griffin's Stegosaurus fossil has found a temporary home at the American Museum of Natural History.

The 150-million-year-old fossil known as "Apex" will be displayed at the Manhattan-based museum starting December 8. It will arrive at the American Museum of Natural History as part of a special loan from Griffin, who purchased it during a Sotheby's auction for $44.6 million in July.

Commercial paleontologist Jason Cooper discovered Apex in May 2022 at Morrison Formation near Dinosaur, Colorado. It is 11.5 feet tall, 27 feet long, and nearly 80% complete. Apex is thought to be the largest and one of the most complete Stegosaurus specimens discovered so far.

Sotheby's, which initially expected the fossil to go for about $6 million, said in a statement that Apex set off a "bidding battle" and was "the most valuable fossil ever sold at auction."

At the time, some paleontologists argued it shouldn't have been privately sold but rather used for educational purposes.

"We are thrilled to have Apex on view at the Museum and grateful to Ken Griffin for his commitment to sharing this magnificent specimen with the public and for partnering with our Museum to do so," Sean M. Decatur, President of the American Museum of Natural History, said in a press release.

The press release said Griffin's decision to loan the fossil will allow scientists in the museum's Division of Paleontology to study it as part of a new research initiative.

A representative for Griffin said he also provided sampling needed for scientific research and funding for educational programming. A postdoctoral fellow will also have the opportunity to research Apex alongside other Stegosaurus specimens.

"Apex offers a unique window into our planet's distant past, and I'm so pleased to partner with the American Museum of Natural History to showcase it at one of our country's preeminent scientific institutions," Griffin said in a statement to Business Insider. "I am grateful that millions of visitors and researchers will now be able to see and learn from this magnificent specimen of the Late Jurassic Period."

He added: "The joy and awe every child feels coloring a Stegosaurus with their crayons will now be brought to life for the millions of people who have the opportunity to see this epic dinosaur in person."

• Billionaires are relocating more since the COVID-19 pandemic, per a report from Swiss bank UBS.
• UBS said that Switzerland, the UAE, Singapore, and the United States are popular destinations.
• "The shock of the pandemic put a premium on first-class healthcare," UBS wrote.

Billionaires have increased the frequency at which they are relocating overseas since the COVID-19 pandemic struck, the annual Billionaire Ambitions Report from UBS says.

The Swiss banking giant's report, which tracks sentiment among the world's superrich, found that since 2020, 176 billionaires have relocated around the world. With a global population of 2,682 as of April 2024, this represents around one in 15 billionaires, or roughly 6.5%.

The outflow of billionaires between 2020 and 2024 was most pronounced in Eastern Europe, where there was a net outflow of 29 billionaires, likely reflecting ultrarich citizens leaving the region amid the conflict between Russia and Ukraine.

Central and South America, Oceania, and Southeast Asia also saw net outflows of billionaires, UBS said.

Meanwhile, billionaires have been moving to countries including Switzerland, the UAE, Singapore, and the United States.

The Middle East and Africa region has also attracted new billionaires, with individuals with a combined net worth of over $400 billion moving to the region in the past four years.

UBS notes that one driving factor behind the superrich relocating is the increased value of good healthcare in the post-pandemic world.

"The shock of the pandemic put a premium on first-class healthcare," the report's authors wrote.

"As a group, billionaires are ageing, and their families are growing. Naturally, healthcare and education become more important."

Another driver, UBS said, is moving to "jurisdictions where legal structures support wealth transfer."

In other words, living in a place where the transfer of wealth through inheritance and other means is not subject to high levels of taxation.

"People are relocating to jurisdictions not just for tax benefits, but also for safety and political reasons," one American billionaire told the authors of the survey.

"I moved several years ago with my family to a country, state and city that affords the benefits most seek," the unnamed billionaire added.

"Unless the political divide addresses failed policies that have yet to curb crime, lack of rule of law and safety, as well as fostering an economic climate that unleashes potential, I fear the trend will continue."

Billionaires also value locations that support business — especially with geopolitical tensions remaining elevated globally, the report said.

According to UBS, total billionaire wealth rose by 121% worldwide from $6.3 trillion to $14 trillion between 2015 and 2024. At the same time, the number of billionaires grew from 1,757 to 2,682. This number peaked in 2021, when there were 2,686 — and has flatlined since.

• President-elect Donald Trump's net worth is estimated to be $5.6 billion, according to Forbes.
• The entire Trump family could be worth over $6.7 billion, including the reported net worths of the Trump children.
• The Trumps spend their money lavishly, from a hefty real-estate portfolio to an aviation fleet and designer clothes.

President-elect Donald Trump's net worth is currently estimated to be $5.6 billion, according to a Forbes report from November 2024.

And that's not to mention the individual net worths of his adult children: a reported $25 million each for both Donald Trump Jr. and Eric Trump, according to Forbes estimates from 2019; and a reported $10 million for Tiffany Trump, according to Celebrity Net Worth. Ivanka Trump, who runs her own business, has the largest net worth of all the children. She and her husband Jared Kushner are estimated to be worth around $1.1 billion, as best ascertained by ethics filings reflecting the couple's real estate holdings and additional investments.

Combined, that means the entire Trump family's fortune could be well over $6.7 billion.
