The United States added 441,078 new millionaires in 2025 — more than 1,200 a day and nearly half of all new millionaires worldwide — marking the fastest expansion of seven-figure wealth on record, according to the UBS Global Wealth Report 2026.

The Swiss bank's annual survey across 56 markets put the total U.S. millionaire population above 23.6 million, more than 40% of the global tally.

Global personal wealth jumped 10.8% last year, the strongest pace since 2017 and more than double the rate posted in either 2023 or 2024.

Close to 1 million people joined the millionaire ranks worldwide, and every market in the UBS sample finished the year with more millionaires than it had at the start.

A strong year for U.S. stocks helped drive the increase. About 79% of U.S. household wealth is held in financial assets — the fourth-highest share in the UBS survey — allowing the market rally to disproportionately boost the wealth of invested households.

A weaker dollar lifted the rest of the field.

The euro rose nearly 9% against the dollar, boosting Europe's wealth totals when measured in U.S. dollars.

The United Kingdom added more than 43,000 millionaires. France, Spain, Japan, and India each added more than 30,000.

Eastern Europe led the percentage rankings, with Lithuania up 8% and Turkey, Latvia, and Hungary each up more than 5%.

UBS reported that median wealth, the figure closer to that of a typical household, fell in most countries it tracks, even as averages climbed.

Households worth between $5 million and $100 million have seen the fastest wealth growth since 2000, with inflation-adjusted wealth rising an average rate of 6.1% a year. By comparison, households worth $1 million to $5 million saw average annual growth of 4%.

The share of adults with less than $10,000 in wealth fell from nearly 75% in 2000 to just over 41%. At the same time, about 1.5% of adults in the countries and territories surveyed had at least $1 million in wealth.
