The number of billionaires reached a record 3,795 in 2025 as artificial intelligence investments significantly boosted market valuations and personal fortunes.
What Happened
Record Wealth Accumulation: The global billionaire population expanded to 3,795 individuals in 2025, representing an 8.2% increase in headcount. Total combined net worth for this group climbed by 12.8% to reach an unprecedented $15.1 trillion, fueled largely by the rapid expansion of the artificial intelligence sector.
AI Market Impact: Altrata identified that companies investing at least $30 million in AI over the last five years outperformed peers by 23% in market capitalization growth. This concentration of wealth in tech-centric firms has created significant volatility, with major fortunes fluctuating sharply alongside swings in chip stock valuations.
Concentration of Capital: The report highlights a growing divide within the billionaire class, noting that 29 'superbillionaires' now control $4.1 trillion, or 27% of total billionaire wealth. This represents a substantial shift from 2017, when a smaller group of ten individuals held only 7.2% of the total wealth.
Regional Growth Trends: North America led the world in billionaire growth with an 11.6% rise, bolstered by the region's dominance in both public and private technology markets. While Europe and Asia also saw gains, the report emphasizes that 2025 was a uniquely positive year across all major asset classes despite ongoing geopolitical trade tensions.
