Global Billionaire Population Set to Surge by 2031

According to a recent analysis by the real estate firm Knight Frank, the number of billionaires worldwide is projected to rise from 3,110 in 2026 to approximately 3,915 by 2031, marking a 25% increase. This growth is part of a broader trend in wealth accumulation, particularly among multimillionaires, whose numbers have surged from 162,191 in 2021 to 713,626 today. Liam Bailey, head of research at Knight Frank, attributes this rapid wealth accumulation to advancements in technology and artificial intelligence, stating, “The ability to scale a business has never been higher... supercharged by tech and AI.”

The forecast indicates that the most significant growth in billionaire numbers will occur in oil-rich Saudi Arabia, where the count is expected to increase from 23 in 2026 to 65 by 2031. Other countries projected to see substantial increases include Poland, with a rise from 13 to 29 billionaires, and Sweden, which is expected to grow from 32 to 58. While North America currently houses nearly a third of the global billionaire population, projections suggest that by 2031, the Asia Pacific region will surpass it, accounting for 37.5% of the total compared to North America's anticipated 27.8%.

The increasing mobility of the ultra-wealthy is influenced by various factors, including political volatility, tax reforms, and tighter regulations. Rory Penn, chairman of the private office business at Knight Frank, noted that the ultra-wealthy are gravitating toward urban centers that offer economic opportunities and regulatory stability. He remarked, “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.”

The rapid accumulation of wealth among billionaires has raised concerns about growing economic inequality. The World Inequality Report highlighted that fewer than 60,000 individuals, representing 0.001% of the global population, control three times the wealth of the bottom half of humanity. This disparity has prompted calls for increased taxation on the super-rich, with organizations like Oxfam reporting a record number of billionaires created last year, pushing the total above 3,000 for the first time.

While Knight Frank's analysis presents a clear picture of rising billionaire numbers, it contrasts with reports of declining billionaire counts in certain regions, such as the UK, where the number fell from 165 to 156 in 2025. This decline has been attributed to the abolition of the non-dom regime, leading to speculation about the super-rich relocating to more favorable tax environments.
