10 Countries with the Fastest-Growing Ultra-Rich Populations

The global landscape of extreme wealth is changing rapidly. According to Knight Frank’s latest wealth analysis, the population of ultra-high-net-worth individuals (UHNWIs)—people with a net worth of more than US$30 million—is expanding particularly quickly in a number of emerging and established economies.

Globally, the number of UHNWIs increased from 551,435 in 2021 to 713,626 in 2026, highlighting the remarkable pace of wealth creation worldwide.

Leading the growth rankings is Indonesia, where the ultra-rich population is projected to increase by 82%. The country’s expanding economy, growing private sector and rising domestic wealth are helping create a new generation of wealthy entrepreneurs and investors.

Saudi Arabia and Poland follow, each with projected growth of 63%, reflecting significant wealth creation in both the Middle East and Central Europe.

Vietnam and Australia are next, with their UHNWI populations expected to grow by 59%. Vietnam is benefiting from rising private wealth, international investment, tourism and infrastructure development, while Australia continues to attract and generate substantial high-level wealth.

Knight Frank also highlights Vietnam as an increasingly important luxury-property market as domestic wealth expands.

Sweden is projected to record 55% growth, followed by the United States at 54%. Although the US has a lower percentage growth rate than several emerging markets, its sheer scale makes it the world's dominant wealth-creation engine.

Knight Frank says the US accounted for 41% of all new individuals worth at least US$30 million created during the five years to 2026.

Completing the top ten are Romania, with 50% growth, the Philippines, at 49%, and Singapore, at 46%. These figures demonstrate that the expansion of extreme wealth is no longer concentrated solely in traditional financial centers.

Instead, rapidly developing economies and established markets alike are producing more individuals with substantial investable wealth.

Overall, Knight Frank’s findings point to a broader geographical diversification of global wealth. Indonesia, Saudi Arabia, Poland and Vietnam stand out as particularly dynamic markets, while countries such as the US and Australia combine strong growth with already substantial wealthy populations.

As this trend continues, the growing number of UHNWIs is likely to influence luxury real estate, investment, entrepreneurship and private capital flows around the world.
