The Walmart heirs' combined estimated net worth is nearly $380 billion.
All three of Sam Walton's surviving children have now made it into the $100 billion club.
In public, the Waltons live relatively modest lifestyles despite their wealth.
All three of Walmart founder Sam Walton's surviving children have made it into the $100 billion club as the retail giant's share price continues to soar.
The combined wealth of the Walmart heirs — which include founder Sam Walton's children, Rob, Jim, and Alice, as well as his grandson Lukas — is nearly $380 billion, according to the Bloomberg Billionaires Index.
Together, they're significantly ahead of the top individual names on the list, such as Jeff Bezos, Bernard Arnault, or Mark Zuckerberg, though Elon Musk has recently seen his fortune outstrip their collective net worth.
While some have worked in the family business — whether that's serving on the company board or working to manage the family's wealth — others chose to pursue areas of personal passion.
Sam Walton, the original man behind the company that now encompasses both Walmart and Sam's Club, set his family up for financial success when he divided the ownership before he died.
Most recently, the Walton children have expanded voting control to their own, giving eight of Sam's grandchildren a say in the family holdings.
Sam wasn't a man of flashy luxury, but you can see how his children are living a slightly more lavish life now. Here's a look at how the Walton family empire spends its money:
Sam Walton opened the first Walmart store in Rogers, Arkansas, in 1962.
He married Helen Robson on Valentine's Day in 1942.
Together, they had four children: Rob, John, Jim, and Alice.
By the time Sam died in 1992, he had set up the company ownership in a way that minimized the estate taxes anyone on the receiving end would have to pay.
He set up his ownership of Walmart's stock in a family partnership — each of his children held 20% of Walton Enterprises, while he and Helen each held 10%. Helen inherited Sam's 10% tax-free when he died.
John served in Vietnam as a Green Beret. When he returned from the war he held a series of jobs — like the Walmart company pilot, a crop duster, and the owner a few yachting companies — before becoming a Walmart board member.
In 2013, Christy decided to sell their Jackson Hole mansion. She also sold the family's ranch for an undisclosed price in 2016 after listing it for $100 million in 2011.
James "Jim" Walton is the youngest son of Walmart founder Sam Walton. He is 76 years old.
He is chairman of the board of the family's Arvest Bank Group. One of the state's largest banks today, Arvest Bank has assets totaling more than $26 billion.
He also served on the Walmart board, starting in 2005 to fill the vacancy after his brother John died. Jim Walton's son, Steuart, took over his father's seat on the board in 2016.
Now, he presides over Walton Enterprises — the private company that deals with the investments and finances of the Walton family only — from modest offices in Bentonville, Arkansas.
The youngest of founder Sam Walton's children, Alice Walton is worth $112 billion, according to Bloomberg. She has been divorced twice and has no children. She is 75 years old.
Alice has never taken an active role in running the family business.
Instead, she became a patron of the arts, which she fell in love with at a young age.
When she was 10, she bought her first work of art: a reproduction of Picasso's "Blue Nude" for about $2, she told The New Yorker.
She has an immense private art collection, with original works from Andy Warhol and Georgia O'Keeffe. Alice opened a museum in Bentonville called Crystal Bridges in 2011 to house her $500 million private art collection.
The collection includes a Georgia O'Keeffe painting that Alice spent $44.4 million on in 2014 — the biggest sale for a woman's piece of art in history.
Her Millsap, Texas, property, Rocking W Ranch, sold to the Three Amigos Investment Group of Kermit, Texas, in September 2017 for an undisclosed amount.
It had an initial asking price of $19.75 million, which was reduced to $16.5 million. The working ranch had over 250 acres of pasture and outbuildings for cattle and horses.
In January 2016, Alice donated 3.7 million of her Walmart shares — worth about $225 million at the time — to the family's nonprofit, the Walton Family Foundation.
Sam and Helen started the foundation as a way to teach their children how to give back and how to work together.
The charity awards millions of dollars in grants to causes that align with the foundation's values.
The foundation has three main areas of focus:
The foundation's focus on education was led by John. His brother Jim said John was really interested in being able to give parents choices when it came to their child's schooling.
Rob spearheaded the foundation's venture into environmental protection. One of the first grants they gave helped develop a sustainable fisheries label.
A commitment to the family's home of Arkansas is another large part of the foundation. The website says this area of focus is about "advancing our home region of Northwest Arkansas and the Arkansas-Mississippi Delta."
Walmart Inc., which owns Walmart and Sam's Club, is the largest retailer in the US in terms of revenue.
Even though the Walton family is raking in billions as a result of the company's success, they remain relatively under-the-radar in terms of flashing their wealth — much like their patriarch, Sam, did in the early years.
In December, Walmart disclosed that Sam's children had granted voting rights to eight of their own children, bringing the total number of voices in the family fortune from three to eight, and keeping with Sam's vision for his legacy.
