There are 45 American families worth at least $10 billion, and the richest one is wealthier than Elon Musk, Forbes says, Report informs, citing Business Insider.
The Walmart founder Sam Walton's heirs still own about 45% of the retail giant, giving them a combined net worth of $267 billion as of January 16, a new Forbes ranking of decabillionaire families shows. That figure dwarfs the Tesla and SpaceX CEO's net worth of about $202 billion.
Forbes estimates the 45 superrich families are collectively worth about $1.3 trillion, or roughly 10 times Warren Buffett's personal fortune.
The Mars family is a distant second to the Waltons, with a $117 billion fortune spread across the confectionery clan. There are plenty of other well-known families on the list, with names such as Koch, Lauder, Hearst, and Marriott.
Other household names, including Carnegie, Vanderbilt, and Getty, have dropped out of the rankings, for reasons ranging from stock-price performance and costly legal disputes to taxes on stock sales and charitable giving.
The descendants of John D. Rockefeller, the nation's richest man in his prime, barely made Forbes' list, with a $10.3 billion fortune.
