How does the U.S. list compare?

That is nearly double its 2024 figure of $267 billion. Koch follows at $157 billion and Mars at $129 billion. Both Bloomberg and Forbes put the Waltons first despite different totals.
For U.S. peer comparison, Koch and Mars are the next closest dynasties. Readers can use the Forbes U.S. list for domestic peers and Bloomberg for global peers.
Why are Musk and Bezos missing?
According to Bloomberg methodology summaries, the global family ranking requires about $46.4 billion minimum. It excludes first-generation, single-heir and opaque-source fortunes.
That rule keeps Jeff Bezos and Elon Musk off the family list. Their wealth counts as founder wealth rather than multi-heir dynastic wealth. A high individual net worth does not place a name on this peer table.
What will shift future peer rankings?
According to Reuters on the UBS Billionaire Ambitions Report, 91 heirs inherited a record $298 billion in the 12 months to April 2025. That was up more than one-third from 2024 and the most since UBS tracking began in 2015.
Reuters also reports UBS projects at least $5.9 trillion will pass to heirs over the next 15 years Reuters report on the UBS findings. Peer rankings will increasingly turn on succession, trusts and asset preservation rather than founders' operating results.
