Mirror, mirror on the wall, who's the richest of them all? In Illinois, it's still Citadel's Ken Griffin, according to Forbes 31st annual World's Billionaires List.
The hedge fund founder leads a pack of 16 Illinois billionaires who made this year's list. Also making the Illinois list are five Pritzkers, scions of the family that founded the Hyatt Hotel chain; real estate mogul Sam Zell; the father of Beanie Babies, Ty Warner; and Groupon's Eric Lefkofsky, to name a few.
The Illinois list is composed mostly of the same cast of characters as last year, with all but two people increasing their wealth.
Griffin's $8 billion net worth ranks him No. 166 on the international list. He remains at the top of the list for Illinois and increased his wealth $500 million since last year.
Zell is right behind him in the Illinois rankings, with a $5 billion net worth, and J.B. Pritzker, who is exploring a 2018 Democratic bid for governor, landed the No. 3 spot, with a net worth of $3.4 billion.
Other notable names include Warner, who's tied for sixth in Illinois with $2.5 billion, and Morningstar founder Joe Mansueto, tied at No. 10 in Illinois with $2.2 billion. He's followed by Lefkofsky at No. 12 with $1.9 billion.
Pritzkers who made the Illinois list include Thomas Pritzker with $3.2 billion, Jean (Gigi) Pritzker with $2.5 billion, Jennifer Pritzker with $1.8 billion and Nicholas Pritzker II with $1.4 billion.
Tied with Nicholas Pritzker and CDW founder Michael Krasny for the final spot on the Illinois list is Bulls and White Sox Chairman Jerry Reinsdorf.
What do these billionaires have to thank for their good fortune? It varies, said Chase Peterson-Withorn, a Forbes reporter who helped compile the list.
Griffin's wealth is up because Citadel did well, for example, and Lefkofsky's increase likely came after Uptake Technologies, the predictive analytics startup he helped found, raised $40 million and was valued at $2 billion in the deal.
Overall, the strong markets since the election likely fueled the boosts, Peterson-Withorn said.
"The stock market is doing well, commodity prices are up, and the world is just minting new billionaires," he said.
The only folks who didn't build their wealth this year were real estate and casino magnate Neil Bluhm, whose net worth fell by $200 million to $3.2 billion, and Nicholas Pritzker, whose wealth stayed the same.
Penny Pritzker also isn't on the Illinois list this year because Forbes changed her place of residence to Washington, D.C., in its database. She served as the U.S. secretary of commerce until January. She still made the overall list, coming in at No. 814 with $2.5 billion, up $200 million from last year.
The Forbes list this year has 2,043 billionaires, the most it's ever had. It has 233 more billionaires than 2016's list.
Forbes uses stock prices and exchange rates from around the world to calculate net worths for its list. It's a snapshot of wealth taken Feb. 17, and the company warns that some net worths have since changed. It lists only individuals, steering clear of multigenerational wealth.
Worldwide, Bill Gates took the No. 1 spot for the fourth year in a row. But Amazon's Jeff Bezos had the best year, adding $27.6 billion to his fortune, up to $72.8 billion. He moved into the top three, up two spots from last year's No. 5 ranking. Warren Buffet had the biggest gain in wealth since Donald Trump was elected president in November, and he snagged the No. 2 spot from Zara founder Amancio Ortega, who fell two spots to No. 4.
And President Trump? He's the 544th richest person in the world, according to the list, with a net worth of $3.5 billion.
