The first year of the second Trump administration was a very happy new year for the US billionaire class. The richest 15 billionaires, all with assets more than $100 billion, saw their combined wealth surge 33 percent, from $2.4 trillion to $3.2 trillion. This is double the growth of the S&P 500 over 2025, which was 16.4 percent.
Over 2025, the combined wealth of all US billionaires climbed to $8.1 trillion, a 21 percent increase over 2025, up from $6.7 trillion exactly a year ago.
Based on an Institute for Policy Studies analysis of data from the Forbes real time billionaire list from 2025, there are 935 billionaires in the United States with combined wealth totaling $8.1 trillion at the close of 2025 markets. This is an increase from 813 US billionaires at end close of 2024 markets, with combined wealth of $6.7 trillion.
The richest three American wealth dynasties — the Waltons, Mars, and Koch families — saw their wealth accelerate from $657.8 billion to $757 billion in one year.
[Note: Bloomberg reported global billionaire wealth increased $2.2 trillion over 2025, in an analysis released several days before the market closed at 4pm on Dec. 31. The market fluctuated considerably in the final days of 2025.]
