Global Billionaire Population Poised for Dramatic 25% Increase by 2031
The number of billionaires worldwide is projected to surge by a staggering 25% over the next five years, according to new analysis from the estate agency Knight Frank. This rapid expansion could see the global billionaire count reach nearly 4,000 individuals by 2031, up from the current total of 3,110.
Tech and AI Supercharge Wealth Creation
Liam Bailey, head of research at Knight Frank, attributes this explosive growth to the "supercharged" effect of technology and artificial intelligence on wealth generation. "The ability to scale a business has never been higher," Bailey explained. "That has fed into the ability to make big fortunes quickly, supercharged by tech and AI."
The analysis reveals that the multimillionaire class is expanding even more rapidly. The number of individuals with a net worth of at least $30 million has skyrocketed from 162,191 in 2021 to 713,626 today – representing an increase of more than 300%.
Regional Growth Patterns and Wealth Concentration
Significant regional variations are expected in billionaire population growth:
- Saudi Arabia: Forecast to more than double from 23 billionaires in 2026 to 65 by 2031
- Poland: Expected to more than double from 13 to 29 billionaires
- Sweden: Projected to see an 81% increase from 32 to 58 billionaires
This growth occurs against a backdrop of increasing wealth inequality. Last year's World Inequality Report found that fewer than 60,000 people – representing just 0.001% of the global population – control three times as much wealth as the entire bottom half of humanity.
Geographic Shifts in Billionaire Distribution
Knight Frank's research indicates a significant geographic shift in billionaire populations. While North America currently hosts just under one-third of the world's billionaires, the Asia Pacific region is expected to overtake it by 2031. By that time, billionaires from Asia Pacific are forecast to account for 37.5% of the global total, compared to 27.8% from North America.
Mobility and Investment Patterns of the Ultra-Wealthy
Rory Penn, who chairs the private office business at Knight Frank, noted that wealth creation is accelerating despite a "more complex global economic backdrop." He observed that "the ultra-wealthy are becoming markedly more mobile, yet the list of markets where they feel genuinely comfortable investing or basing their families has narrowed."
Bailey added that political volatility, tax reform, and tighter regulation are pushing the super-rich toward a smaller group of cities that offer both "opportunity and predictability." This trend has been particularly noticeable in the UK, where reports of wealthy individuals relocating have proliferated following the abolition of the non-dom regime.
Current Wealth Leaders and UK Trends
According to the Forbes rich list, Tesla CEO Elon Musk remains the world's wealthiest individual with a net worth of $785.5 billion. Google co-founder Larry Page ranks second with $272.5 billion, while Amazon founder Jeff Bezos holds third place with $259 billion.
In Britain, The Sunday Times rich list identified the Hinduja family as the wealthiest, with a net worth of £35 billion. The UK billionaire count stood at 156 in 2025, marking the biggest decline in the list's 37-year history, down from 165 the previous year.
The charity Oxfam reported that billionaires collectively hold $18.3 trillion in wealth, with a record number created last year that pushed the total above 3,000 for the first time. These findings have intensified calls for global leaders to implement higher taxes on the super-rich, amid concerns about their growing political influence.
