A pandemic hasn’t stopped many of the planet’s wealthiest dynasties from adding to their fortunes
For once the seats were empty in the Bud Walton Arena, home to basketball’s Arkansas Razorbacks and, each summer, host to fathomless wealth.
Covid-19 had come to Walmart Inc. country, canceling the retailer’s “Associate Celebration.” Gone were the thousands of employees, the cameos by Katy Perry or Tom Cruise and the traditional appearance by the heirs of Sam Walton, the world’s richest family.
But even a pandemic hasn’t stopped the relentless growth of their fortune. The Waltons are richer than ever, adding $25 billion in the past year to take their combined fortune to an estimated $215 billion. Years of investment in Walmart’s supply chain and e-commerce capabilities saw a surge in first-quarter sales despite widespread carnage in the U.S. retail sector.

With that much money, you could pile $1 million onto each of the 19,368 seats in the Walton arena and still have enough left to give Walmart’s 2.2 million associates about $90,000 each. The family’s unprecedented fortune is almost $100 billion more than the Mars candy clan in second place.
Kiki McLean, a spokeswoman for the Waltons, declined to comment.
The Ozark clan aren't the only ones to have prospered this year even as the overall net worth of the planet's richest 25 dynasties held steady at $1.4 trillion.

India’s Mukesh Ambani has pulled in more than $20 billion of investment for his digital platforms since April, boosting Asia’s biggest fortune by 61% in the past year even as brother Anil struggled. Switzerland’s Oeri-Hoffmann dynasty added 24% to its net worth with Roche Holding AG shares boosted by sales of Covid-19 tests. Fidelity’s Johnson family rose $9 billion this year to $46 billion.
The concentration of gains mirrors Bloomberg’s ranking of individual billionaires, where Jeff Bezos is similarly pulling away from the rest. Bezos, who would rank second if featured, doesn’t qualify for the family list as his wealth is first generation (see methodology).
These outsized fortunes have sharpened calls for wealth taxes at a time when a pandemic and the Black Lives Matter protests have highlighted runaway inequality. Politicians on the left including Alexandria Ocasio-Cortez and Bernie Sanders have delivered blistering attacks on widening inequality and the growing wealth of billionaires. Former Vice President Joe Biden, the presumptive Democratic nominee, hasn’t embraced a wealth tax, but he’s campaigning on higher rates on the rich and corporations, as well as the closing of estate-tax loopholes.
Even this year’s fallers, including the Kochs who were hit by the oil price crash, and the Kwoks, whose property empire is reeling from the Hong Kong protests, will endure.
“One of the powerful things about intergenerational wealth is they have very long-term time horizons,” said Karen Harding, who heads up the private-wealth group at Boston-based NEPC, which advises ultra-high-net-worth families. “Most family offices are in a position to accept markets go up and markets go down.”
That’s partly testament to long-standing advantages vast wealth affords. Bolstered by years of strategic diversification and family offices that can rival investment banks in their scope and sophistication, the 0.001% can weather economic and social turmoil.
“Of course there was concern when the market sold off,” Harding said. “But quite frankly a lot of families viewed it as an opportunity.”

For one, it made some investments far cheaper. Valuations had become so high that putting capital to work was often prohibitively expensive. Some families were able to act before the markets rebounded. The Kochs may have shed $15 billion this year, but still made a $200 million bet on rental homes in May.
The selloff also created opportunities for succession planning by enabling assets to be transferred to the next generation at depressed valuations.
These considerations are impossibly distant for most in a year when U.S. unemployment is spiking and the federal government resorted to mailing its citizens checks. But the Waltons’ record pile is a telling illustration of the long-lasting impact of that kind of forward planning.
In 1953, almost a decade before he opened the first Walmart, Sam Walton put his assets into a partnership and gave a 20% stake to each of his four children, leaving the remainder for himself and his wife.
“The best way to reduce paying estate taxes is to give your assets away before they appreciate,” he explained in his autobiography.
Walmart is the world's largest retailer by revenue, with sales of $524 billion from more than 11,000 stores worldwide. The Walton family owns about half the retailer, a stake that’s the foundation of the world's biggest fortune.
Frank Mars learned to hand-dip chocolates as a schoolboy. The business he went on to establish is best known for M&Ms and Milky Way and Mars bars, though pet-care products make up about half of the company's more than $38 billion in revenue. The closely held business is owned by members of the Mars family.
Brothers Frederick, Charles, David and William inherited father Fred’s oil firm. A fraternal feud over control of the company in the early 1980s led Frederick and William to leave the family business while Charles and David stayed. It has since grown into Koch Industries, a conglomerate with annual revenue of about $115 billion. The family manage a portion of their wealth through family office 1888 Management.
The 88-year-old monarchy after which Saudi Arabia is named can credit the nation's unrivaled oil reserves for seeding its collective fortune. This net worth estimate is based on cumulative payouts royal family members are calculated to have received over the past 50 years from the Royal Diwan, the executive office of the king. The total wealth controlled by its estimated 15,000 extended members is likely much higher. Many royals have made money through brokering government contracts and land deals and by founding businesses that service state companies, such as Saudi Aramco. Crown Prince Mohammed bin Salman, son of Saudi's seventh monarch, King Salman, personally controls assets worth more than $1 billion.
Dhirubhai Ambani, the father of Mukesh and Anil, started building the precursor to Reliance Industries in 1957. When Dhirubhai died in 2002 without leaving a will, his widow brokered a settlement between her sons over control of the family fortune. Mukesh is now at the helm of the Mumbai-based conglomerate, which owns the world's largest oil refining complex. He lives in a 27-story mansion that’s been called the world’s most expensive private residence.

The Boston mutual-fund empire was founded by Edward C. Johnson II in Boston in 1946. It is now run by his granddaughter, Abigail.

Theo’s side of the family also owns Trader Joe’s, which it bought in 1979.

The collective enterprise of these three Belgian beermaking families has roots in the 14th century. The Van Damme family joined the others when the 1987 merger between Piedboeuf and Artois led to the creation of Interbrew, which merged with Brazil’s AmBev in 2004.
