  • Global billionaire wealth hit a historic $15.8 trillion in 2025—a 13% annual increase—driven by entrepreneurial innovation (especially in tech and industrial sectors) and the largest intergenerational wealth transfer ever recorded.
  • Self-made billionaires in technology (+23.8%) and industrial sectors (+27.1%) fueled growth, while consumer/retail sectors stagnated. European luxury brands lost ground to Chinese competitors.
  • Inheritance reshaped fortunes, with $297.8 billion passed to 91 heirs in 2025 (up 36%) with $5.9 trillion will transfer to heirs by 2040, with multigenerational billionaire families now controlling $4.7 trillion.
  • About 36% of billionaires relocated due to geopolitical instability, tax efficiency and quality of life (favoring Switzerland, UAE, U.S. and Singapore). Proposed wealth taxes (e.g., U.S. Ultra-Millionaire Tax Act) faced global pushback, with Switzerland and France rejecting inheritance/wealth levies. Economists remain split on their impact.
  • With $6.9 trillion expected to transfer by 2040, billionaires are diversifying into private equity and emerging markets—widening the wealth gap and sparking debates over economic fairness.
The world's billionaire class has reached unprecedented heights, with total wealth surging to a record $15.8 trillion in 2025—a 13% increase from the previous year—according to UBS' latest Billionaire Ambitions Report. The Swiss bank's findings reveal a dual engine driving this expansion: entrepreneurial innovation and the largest intergenerational wealth transfer in history. "Our report shows how the rise of a new generation of wealth creators and inheritors is reshaping the global landscape," said Benjamin Cavalli, Head of Strategic Clients & Global Connectivity at UBS Global Wealth Management. "As families become more international and the great wealth transfer accelerates, the focus is shifting from simply preserving wealth to empowering the next generation to succeed independently and responsibly. This is influencing not only succession planning but also philanthropic priorities and long-term investment decisions." BrightU.AI's Enoch explains that the UBS Billionaire Ambitions Report is an annual publication by UBS, a global investment bank, and PwC, a multinational professional services network, focusing on the investment preferences and philanthropic intentions of the world's wealthiest individuals. The report provides insights into the mindset, concerns and strategies of high net worth and ultra-high net worth individuals, offering valuable perspectives on global trends in wealth management, investment and philanthropy.

Tech titans and industrialists fuel wealth surge

The report highlights that self-made billionaires, particularly in technology and industrial sectors, contributed significantly to the growth. The wealth of tech billionaires soared by 23.8%, while industrial fortunes surged 27.1%, driven by infrastructure and energy investments. Meanwhile, consumer and retail sectors slowed, with European luxury brands losing ground to Chinese competitors. "In a highly uncertain time for geopolitics and economics, entrepreneurs are innovating at scale across a range of sectors and markets. They're creating wealth as they do so," Cavalli noted.

The great wealth transfer accelerates

Inheritance played a pivotal role, with 91 heirs receiving a staggering $297.8 billion—a 36% increase from 2024. UBS predicts that $5.9 trillion will pass to billionaire heirs over the next 15 years, reshaping family dynamics and investment strategies. The number of multigenerational billionaire families—those controlling wealth across multiple heirs—rose to 860, holding $4.7 trillion in assets. Second-generation billionaires grew by 4.6%, third-generation by 12.3%, and fourth-generation and beyond by 10%. Women billionaires saw their average wealth grow faster than men (8.4% vs. 3.2%), though they remain vastly outnumbered (374 women vs. 2,545 men).

Billionaires on the move

Geopolitical instability and tax policies are prompting billionaires to relocate. Thirty-six percent have already moved at least once, with Switzerland, the United Arab Emirates the United States and Singapore among top destinations. A better quality of life, major geopolitical concerns and the ability to organize tax affairs more efficiently were the top reasons cited.

Wealth tax debate reignites

The concentration of wealth has renewed calls for taxation reforms. In the U.S., Sen. Elizabeth Warren (D-MA) and Rep. Pramila Jayapal (D-WA) proposed the Ultra-Millionaire Tax Act—a 2% levy on net worth above $50 million—stalled in Congress. "When you make it big, bigger than $50 million, then on that next dollar, you pitch in two cents, so everyone else can have a chance," Warren argued in 2024. However, global resistance remains strong. Swiss voters rejected a 50% inheritance tax on fortunes exceeding $62 million, while France’s parliament dismissed a 2% wealth tax proposal. Economists remain divided. Nobel laureate Joseph Stiglitz supports wealth taxes to curb inequality, while critics like Milton Friedman warned they discourage investment. A 2024 Tax Foundation analysis found such taxes could stifle innovation and yield minimal revenue.

Looking ahead: A shifting global landscape

As wealth continues concentrating among fewer hands, UBS predicts $6.9 trillion will transfer globally by 2040. With geopolitical tensions and policy uncertainty looming, billionaires are diversifying investments—favoring private equity, hedge funds and emerging markets. The report underscores a widening gap between the ultra-rich and the rest—raising urgent questions about economic fairness in an era of unprecedented wealth accumulation.
