The United States continues to dominate global wealth, holding the top position among countries with the most millionaires in 2025, according to newly released data from sources including the UBS Global Wealth Report.
The latest figures show the U.S. is home to about 23.8 million dollar millionaires, representing nearly 40% of the world’s total millionaire population—a lead that places it far ahead of all other nations.
Why the US Leads the World in Millionaires
Analysts attribute America’s strong lead to a combination of factors, including a resilient stock market, a mature investment ecosystem, high levels of home ownership, and a steady flow of new wealth from technology and financial services.
By comparison, Mainland China ranks second, with 6.3 million millionaires, reflecting continued growth in private wealth despite broader economic headwinds.

Although the U.S. leads in total numbers, Switzerland and Hong Kong stand out for having the highest concentration of millionaires relative to their adult populations. Wealth experts note that financial stability, tax efficiency, and global investment access play a major role in these rankings.
What This Means for Global Wealth in 2025
