Global Billionaire Boom: Wealth, AI Growth, and Rising Inequality Forecast for 2031
Kazi Abul Monsur#
In the coming years, the number of ultra-rich individuals (billionaires) in the global economy, along with their total wealth, is expected to increase at an extraordinary pace. According to a comparative report by Visual Capitalist based on the latest “Wealth Report” from the international real estate and wealth advisory firm Knight Frank, these striking findings have emerged.
Between 2026 and 2031, this five-year forecast shows that driven by remarkable technological advancement and economic diversification, the number of billionaires worldwide will rise by 25% from the current 3,110 to approximately 3,915. Their combined wealth is projected to reach around $18.3 trillion. In terms of percentage growth, Saudi Arabia is expected to experience the highest increase in both wealth and billionaire numbers by 2031. Due to Crown Prince Mohammed bin Salman’s “Vision 2030” mega project, which focuses on economic diversification and massive investment in non-oil sectors, the country’s billionaire wealth is projected to increase by about 183% by 2031. Currently (in 2026), Saudi Arabia has 23 billionaires, but this number is expected to nearly triple to 65 by 2031.
Top 10 Countries: Europe and Asia Dominate
In the ranking of the top 10 countries by projected percentage growth in billionaire wealth, Poland stands second after Saudi Arabia with a projected growth rate of 123%, largely driven by the expansion of its emerging technology sector. The top 10 list for overall wealth growth by 2031 is as follows:
1st Saudi Arabia – 183%
2nd Poland – 123%
3rd Sweden – 81%
4th Australia – 77%
5th Denmark – 75%
6th Japan – 65%
7th Mexico – 63%
8th Philippines – 63%
9th Norway – 53%
10th India – 51%
The presence of three Nordic countries (Sweden, Denmark, and Norway) in the top 10 highlights the strong concentration of wealth accumulation in Northern Europe.
India Leads in Absolute Numbers
While India ranks 10th in percentage growth (51%), it is expected to lead the world in the total number of billionaires by 2031. In 2026, India has 207 billionaires, and this number is projected to increase by 106, reaching 313 by 2031.
Knight Frank’s Head of Global Research, Liam Bailey, stated:
“We are witnessing one of the most significant global wealth redistributions in modern history. While the United States and China remain the dominant powers, India and several rapidly growing economies are reshaping the global landscape.”
What Is Driving Wealth Growth?
According to economic analysts, the biggest driver behind this “supercharged” wealth creation among billionaires is the technology sector and artificial intelligence (AI). Digital platforms and AI-driven startups are enabling individuals to build massive businesses and empires in a very short time.
In addition, industrialization, rapid infrastructure development, strong stock market performance, and the resilience of private capital despite pandemics and geopolitical crises are also playing key roles in generating billionaire wealth.
Rising Inequality and Global Concerns
Alongside this rapid increase in billionaire wealth, global economic inequality is also intensifying, raising concerns from international organizations such as Oxfam.
According to the latest “World Inequality Report,” fewer than 0.001% of the global population (less than 60,000 ultra-wealthy individuals) collectively hold three times more wealth than the bottom half of humanity—around 4 billion people.
As a result, many are calling for increased taxation on the ultra-wealthy, including proposals for a global wealth tax to help regulate their growing economic and political influence.
Final Outlook
This Knight Frank report is primarily based on current market dynamics and economic trends. However, these projections may change due to domestic political conditions, global market volatility, inflation, or unexpected geopolitical crises.
Nevertheless, overall, there is little doubt that the coming era will be shaped significantly by technology-driven billionaires.
