The wealth of the Waltons, the world’s richest family, is up $32 billion so far this year to $475 billion, according to the Bloomberg Billionaires Index. The only person ahead of them is Elon Musk, whose net worth is up $62 billion to $682 billion in 2026.
The Waltons are unusual among the mega-rich because they inherited their wealth. Most of the people at the top of the rich lists are founders or early employees, usually of tech firms. These include Elon Musk of Tesla, Larry Ellison of Oracle, Bill Gates of Microsoft, Jensen Huang of Nvidia, Mark Zuckerberg of Meta, and Larry Page and Sergey Brin of Alphabet. And, of course, there is Warren Buffett.
Musk’s net worth has risen primarily because of a new valuation of SpaceX, which was recently pegged at $1.5 trillion. That is $800 billion more than late last year. Furthermore, SpaceX is a candidate to go public in 2026, and Musk owns 40% of the company.
The Walton math is simpler. The family and its foundations own 44% of Walmart Inc. (NYSE: WMT | WMT Price Prediction). Its stock price is up 7% this year, and its market cap is $950 billion. For the most recent quarter, Walmart reported revenue of $180 billion, which was up 6% from the same quarter a year earlier. Earnings rose 35% to $0.77 per share. Those figures beat Wall Street estimates, which has helped the stock.
Forbes and Bloomberg provide the most well-respected billionaire data. Last year, each rated the Waltons as the world’s richest family. Again, both media pointed out that none of its members has done anything to build the fortunes. They are simply descendants of Sam Walton, Walmart’s founder. He started the company in 1962. It is America’s largest company by revenue (about $720 billion this year) and number of U.S. employees (1.6 million).
There should probably be two rich lists rather than one. The division should not be between families and individuals. It should be between builders and inheritors. They come from different places and are divided largely by those who took risks and those who did not.
