Countries with the Fastest Billionaire Growth
These countries have the fastest growth of billionaires for the next five years.
According to the latest edition of Knight Frank’s Wealth Report 2026, the global billionaire landscape is set for dramatic change between 2026 and 2031.
While traditional wealth centers such as the United States and Western Europe will remain influential, some of the fastest growth in billionaire populations is expected to come from emerging and rapidly transforming economies.
Leading the ranking is Saudi Arabia, where the number of billionaires is forecast to surge by an extraordinary 183% by 2031. The kingdom’s economic diversification efforts under Vision 2030, combined with large-scale investments in technology, infrastructure, tourism, and real estate, are helping create new opportunities for wealth generation.
In second place is Poland with projected billionaire growth of 123%. Poland’s strong economic expansion, growing entrepreneurial sector, and increasing integration with global markets have positioned it as one of Europe’s most dynamic wealth-creation hubs.
Several developed economies are also expected to record remarkable gains. Sweden is projected to see billionaire growth of 81%, followed by Australia at 77% and Denmark at 75%. Their success is supported by innovation-driven industries, stable financial systems, and strong investment environments.
Across Asia, several nations are forecast to experience substantial growth. Japan is expected to expand its billionaire population by 65%, while both Philippines and India are projected to grow by 63% and 51% respectively. Indonesia is also expected to post a strong 49% increase, reflecting the region’s expanding middle class, digital economy, and investment activity.
Elsewhere, notable growth is forecast in Mexico (63%), Norway (53%), Austria (50%), South Africa (40%), and Spain (40%). Meanwhile, Malaysia (39%), Singapore (35%), Italy (34%), Canada (33%), Turkey (31%), and Brazil (31%) complete the top 20 list.
The report highlights a broader shift in global wealth creation, with new economic centers emerging across Asia, the Middle East, Eastern Europe, and Latin America. As technology, entrepreneurship, and capital investment continue to reshape economies, the next generation of billionaires is expected to come from a far more diverse range of countries than ever before.
