A powerful rebound in global markets, a resurgence in corporate dealmaking, and a wave of inherited wealth helped create 287 new billionaires this year, pushing the worldwide billionaire count to more than 2,900, according to the newly released UBS Billionaire Ambitions Report 2025.

The report shows that total billionaire wealth climbed to a record high of $15.8 trillion by the end of the third quarter, reflecting a 13 percent increase from the previous year. Among the 2,919 billionaires identified, 2,059 accumulated their fortunes through their own enterprises, while 860 inherited substantial estates or family businesses.

This year marks the second-largest annual increase in billionaires since UBS began tracking the data. Only 2021 outpaced it, with 360 newcomers during the height of the post-pandemic market boom. Over the last four years, 727 individuals joined the billionaire ranks—an overall expansion of 27 percent in the global population of ultra-wealthy individuals.

While stories often highlight artificial intelligence breakthroughs and digital technology moguls, the 2025 class of new billionaires reflects broader economic forces. This year’s group spans industries such as software, genetics, hospitality, infrastructure finance, and natural gas. The diversity underscores the fact that wealth creation is occurring far beyond Silicon Valley or the AI sector.

Several newly minted billionaires stand out. Ben Lamm, co-founder of Colossal, a genetics and bioscience startup known for its groundbreaking work on species de-extinction, entered the list following rapid valuation gains. Michael Dorrell, co-founder and CEO of Stonepeak, joined after his infrastructure investment firm expanded aggressively in global energy and transportation assets. Meanwhile, Bob Pender and Mike Sabel, co-founders of the liquefied natural gas exporter Venture Global, became billionaires after their company’s public debut in January.

According to Judy Spalthoff, head of the UBS Family Office Solutions Group, these stories illustrate how fertile the global landscape remains for entrepreneurial wealth creation. “There is still tremendous opportunity for new founders to build significant wealth,” she said.

The United States continues to lead the world in producing billionaires. Ninety-two self-made Americans crossed the billion-dollar threshold this year, collectively adding $180 billion in wealth. The U.S. is home to nearly one-third of the world’s billionaires—924 in total—and their combined wealth surged 18 percent to $17.5 trillion. Roughly three out of every four American billionaires built their fortunes rather than inherited them.

However, inheritance is playing an increasingly prominent role in the continued expansion of global billionaire wealth. UBS found that 91 people became billionaires this year through inheritance alone, receiving close to $300 billion in transferred wealth. Of these inheritors, 64 were men and 27 were women. Over the next 15 years, the total value of wealth expected to pass from today’s billionaires to their families is estimated at $5.9 trillion, most of it within the United States.

Yet the approach to generational wealth transition is changing. Many wealthy families are rethinking the once-traditional expectation that children should take over the family business. Instead, more are hiring professional management teams or selling their companies entirely, allowing children to pursue independent careers. One European billionaire interviewed for the report noted that rapid globalization and constant business disruption have made the old model less reliable. Families now prioritize adaptability, education, and personal development over automatic succession planning.

In investment strategy, billionaires remain enthusiastic about public equities despite concerns about overheated valuations and the dominance of AI-driven megacap stocks. According to UBS, 43 percent of surveyed billionaires plan to increase their exposure to publicly traded stocks in the next year, while only 5 percent expect to reduce those holdings.

Private equity sentiment is more nuanced. Half of respondents intend to expand their direct private investments, and 37 percent expect to allocate more to private equity funds. However, 28 percent plan to scale back their commitments to private equity funds, partly due to weaker recent returns and limited exit opportunities. Most plan to maintain current levels of cash, while roughly one-third anticipate increasing their real estate investments.

Confidence in U.S. investment opportunities, however, has slipped. The share of billionaires who consider the U.S. a prime investment destination dropped from 80 percent last year to 64 percent. Conversely, enthusiasm for Europe and China rose significantly. Europe saw its confidence level climb from 18 percent to 40 percent, while China increased from 11 percent to 34 percent.

Daniel Scansaroli, head of portfolio strategy at the UBS Chief Investment Office, explained that global volatility, shifting policies, and high U.S. market valuations are encouraging wealthy families to diversify into markets they perceive as undervalued. “There remains a strong belief in America’s long-term potential,” he said. “But some of the shine has certainly worn off in the process.”

Beyond financial portfolios, billionaire mobility is also reshaping global wealth patterns. UBS found that 36 percent of billionaires have relocated to a different country, and a quarter of them have moved more than once. An additional 9 percent are considering relocating in the near future. Quality of life was cited as the primary reason for moving, with considerations ranging from climate and healthcare access to proximity to family members. Some also pointed to geopolitical stability and tax efficiency as influential factors.

Looking ahead, UBS expects the growth in both the billionaire population and overall billionaire wealth to continue in the coming year. Spalthoff noted that rapid advances in technology and industrial productivity, particularly in the U.S., remain strong catalysts for wealth creation. “We continue to see momentum building,” she said. “With the pace of innovation in tech and manufacturing, especially in the United States, we don’t anticipate a slowdown in billionaire wealth growth anytime soon.”

As global markets evolve and the flow of inherited wealth accelerates, the billionaire class appears poised for another year of expansion—driven not just by technology and finance, but by a broad mix of industries and transformative economic forces worldwide.
