The number of millionaires worldwide surged by nearly one million in 2025, primarily driven by strong stock market performance, according to UBS. The Swiss bank reported that approximately half of the new millionaires originated in the United States, contributing to an average of over 1,200 new millionaires daily, for a total yearly increase of about 441,000.
Global personal wealth rose by 10.8%, marking the most significant increase since 2017 and more than double the growth witnessed in 2024 and 2023. In contrast, there was a notable decline in median wealth across many of the 56 markets analyzed by UBS, highlighting an increasing wealth gap. In the U.S., median wealth per adult decreased by nearly 20% from 2020 to 2025, while average wealth grew by roughly 10% during the same period, adjusted for inflation.
The total population of millionaires globally stands at around 58 million, holding nearly half of the world’s wealth, estimated at $250.6 trillion. UBS economist James Mazeau noted that wealth creation is more pronounced among affluent individuals who have greater exposure to financial markets, particularly as the U.S. stock market experienced an 18% upswing in 2025. The report also indicated uneven wealth growth, with the assets of everyday millionaires (worth $1 million to $5 million) increasing by 170% since 2000, compared to a 343% rise for wealthier individuals.
The report highlighted that the collective net worth of billionaires rose by roughly 25% in the year ending April, with increases partly attributed to a growing number of billionaires. Additionally, the depreciation of the U.S. dollar impacted global wealth creation, as tracking was done in USD. While the U.S. millionaire population grew by only 1.9% in 2025, regions like Europe and the Middle East reported higher gains.
Why this story matters:
- The millionaire increase underscores the widening wealth gap and stock market reliance.
Key takeaway:
- While millionaires increased globally, median wealth declined, indicating disparities in economic recovery.
Opposing viewpoint:
- Concerns remain about the sustainability of wealth growth amid geopolitical tensions and potential economic shifts.
