That’s in addition to a range of other businesses interests, from energy to real estate.

Hawaii: Pierre Omidyar

Sanford has donated over $1 billion of his wealth to charity. Much of it has gone toward Sanford Health, a non-profit health-care delivery system named after Sanford for his generosity.
Maine: Susan Alfond
Estimated net worth: $1.5 billion
Susan Alfond and her siblings inherited a massive fortune after their father sold Dexter Shoe Company to Warren Buffett’s holding company Berkshire Hathaway in 1993 for $433 million in Berkshire stock.
Their father, Harold Alfond, had transformed an old mill into a flourishing shoe factory. He’s sometimes credited with opening the first factory outlet store, selling the rougher shoes that rolled off the line at discount prices.
The company later went out of business in 2001. Buffet said the deal was the worst he’d ever made, but the Alfond family couldn’t be happier with their winnings.

If you’re wondering why the absurdly wealthy Bill Gates doesn’t appear on this list, just ask his even wealthier neighbor.

In 2019, a high-profile divorce saw Jeff Bezos lose a quarter of his Amazon stock to his former wife of 25 years. That still wasn’t enough to knock him off the top spot.
Maryland: Mitchell Rales
Estimated net worth: $4.9 billion
There comes a time when every businessman must make a decision: Work for the man or go his own way? In Mitchell Rales’ case, “the man” was his dad.
In 1979, he left his father’s real estate firm to co-found Equity Group Holdings along with his brother. The duo began plucking up businesses, investing in everything from vinyl siding manufacturers to auto shop suppliers.
After the company adopted a new name, Danaher, in 1984, the acquisitions continued. Today, Danaher owns 24 subsidiaries, including microscope maker Leica and color wizard Pantone.

Arizona: Ernest Garcia II
Estimated net worth: $8.3 billion
It’s a well-worn trope, the billion-dollar business born out of a garage, but it’s a fitting one for used car tycoon Ernest Garcia II.
In 1991, Garcia II swooped in to buy a bankrupt car rental service called Ugly Duckling and merged it with his own finance company. The new Ugly Duckling — later rebranded to DriveTime Automotive Group — specialized in selling and financing cars to people with bad credit.
Forbes says DriveTime is now the fourth-largest used car retailer in America.
The automotive business runs in the Garcia family. In 2012, Ernest Garcia III followed in his father’s footsteps by founding Carvana, bringing affordable used cars to the online marketplace.
If you try to be frugal with your own vehicle, don't forget to look around and save money on car insurance, too.
Michigan: Hank & Doug Meijer
Estimated net worth: $10 billion
Hendrik Meijer, a Dutch immigrant barber, saw an opportunity to make money from clients who needed a bite more than a cut.

She uses some of her fortune to support various environmental causes, including the Galapagos Conservancy.
California: Mark Zuckerberg
Estimated net worth: $88.2 billion
While kids today look at Facebook as that platform their grandparents use, the social network has only grown more popular and powerful with time. Much of that success is thanks to its famous co-founder, Mark Zuckerberg.
If you haven’t seen the story dramatized in the movie The Social Network, the platform with over a billion users started as a pet project Zuckerberg coded in his Harvard dorm in 2003.
Zuckerberg started the website, then known as FaceMash, as a directory for Harvard students. The concept expanded to the other Ivies, then to colleges across the U.S. and Canada, and eventually became the Internet giant we know, love and sometimes fear.
But Zuckerberg hasn’t stopped there. His tech giant keeps busy, bringing notable startups like Instagram and Whatsapp under the Facebook umbrella. The company also took a step into the world of virtual reality with the acquisition of Oculus VR.

Phil Knight used to run track at the University of Oregon before teaming up with his former coach to build one of the biggest footwear companies in the world.
Knight’s Nike makes more than $39 billion in annual revenue and sponsors many high-profile athletes and sports teams around the world. Seems like naming the company after the goddess of victory had the desired effect.
The company’s chairman has donated millions of dollars to his alma maters to support education, athletic programs and renovations.

Estimated net worth: $1.8 billion
Dubbed the “stealth mogul” for keeping a low profile despite his firm’s massive holdings, Jonathan Nelson runs the private equity giant Providence Equity Partners.

Bloomberg has also donated more than $5 billion to causes such as gun control and climate change.
Utah: Gail Miller
Estimated net worth: $1.7 billion
