Ken Griffin recently bought a $90 million waterfront estate in St Tropez.
Griffin currently has a net worth of $41.8 billion, per the Bloomberg Billionaires Index.
Griffin is a top art collector and philanthropist, donating over $2 billion to various causes, according to Citadel.
Billionaire hedge fund founder Ken Griffin has broken records for some of his purchases — from previously buying the most expensive property in Miami history to acquiring a stegosaurus skeleton that made for the most valuable fossil to sell at auction.
The Citadel boss is currently the world's 33rd richest person, with a net worth of $41.8 billion, according to the Bloomberg Billionaires Index.
Some of his fortune was recently spent on a waterfront estate worth over $90 million in the highly exclusive St. Tropez, according to a Wall Street Journal report.
Griffin is also a high-profile philanthropist. A spokesperson for Griffin said he has donated over $2 billion to education, opportunity, and health science initiatives.
Here are some of his more unusual and extravagant purchases:
1. A $90 million St. Tropez estate
The St. Tropez waterfront estate, once owned by photographer Gunter Sachs, was reportedly sold to Griffin for over $90 million, a source familiar with the matter told The Wall Street Journal.
Located on Tahiti Beach, the property spans about two acres with multiple buildings. This purchase adds to Griffin's global collection of luxury properties, including homes in London, New York, and South Florida.
2. A $45 million Dinosaur Skeleton
Griffin purchased Apex, the $44.6 million Stegosaurus skeleton, at a Sotheby's auction this year, setting new fossil auction records.
The nearly 27-foot-long and 11-foot-high skeleton is among the most Stegosaurus skeletons ever found, according to Sotheby's.
Griffin plans to explore lending it to a US institution.
Following the sale, he said, "Apex was born in America and will stay in America."
"[Griffin] shares the art, Constitution, dinosaurs with the public so they can enjoy and learn about them and plans to keep them in the US for future generations," Zia Ahmed, a spokesperson for Griffin, told Business Insider.
3. A $43 million first edition US Constitution
Griffin paid $43.2 million for a first-edition copy of the US Constitution at a Sotheby's auction in 2021, outbidding a group of crypto investors.
This purchase more than doubled its estimated value. This was one of only 13 known copies. Griffin plans to lend the document to a free art museum in Arkansas, a Citadel spokesperson said.
4. $500 million for two art pieces
Griffin spent $500 million in 2016 on Willem de Kooning's "Interchange" and Jackson Pollock's "Number 17A," acquired from David Geffen, according to CNBC.
5. A $238 million penthouse in NYC
In 2019, Griffin bought a $238 million penthouse in New York City's 220 Central Park South, making it the most expensive home ever sold in the US.
This 23,000-square-foot residence adds to Griffin's extensive high-value real estate portfolio. He previously bought a $122 million London mansion and spent a reported $84 million on buying Clavin Klein's former Southampton house.
6. Land in Palm Beach
Griffin broke the Miami property price record in 2022 when he spent more than $100 million on a four-acre estate in exclusive Coconut Grove.
