Billionaire wealth reaches $15.1 trillion in 2025: Altrata report
Key Points:
- The global billionaire population reached a record 3,795 in 2025, driven largely by the artificial intelligence (AI) boom, marking an 8.2% increase and the largest annual rise in five years, according to Altrata.
- Combined billionaire wealth surged 12.8% to $15.1 trillion, with 150 publicly listed companies investing heavily in AI outperforming others by 23% in market capitalization growth from 2024 to 2025.
- The number of "superbillionaires" worth over $50 billion grew to 29, holding 27% of all billionaire wealth, up from 10 individuals representing 7.2% in 2017, highlighting growing wealth concentration at the top.
- Despite rapid wealth gains, AI-related tech stocks remain volatile, causing significant fluctuations in billionaire net worth, exemplified by multi-billion-dollar single-day losses for figures like Elon Musk and Larry Ellison.
- North America led regional billionaire growth with an 11.6% increase, followed by Europe (7.9%) and Asia (6.5%), aided by strong tech markets and broadly positive returns across major asset classes in 2025.
