Here's something remarkable: the world's wealthiest people added $2.2 trillion to their collective fortune in 2025. That's trillion with a T. The combined net worth of the 500 richest individuals hit roughly $11.9 trillion, driven largely by Big Tech and the frenzy around artificial intelligence possibilities.
The gains were heavily concentrated at the top. Just eight individuals accounted for about a quarter of all the wealth gains tracked by Bloomberg's index. Meanwhile, global billionaire wealth overall reached a record $15.8 trillion, powered by self-made entrepreneurs and what's shaping up to be the largest intergenerational wealth transfer in history.
But here's where things get interesting. Despite the impressive performance of U.S. equity markets, more ultra-wealthy individuals are exploring opportunities beyond American borders. The number of wealthy people who see North America as the best short-term opportunity for returns plummeted from 80% to 63% year over year. That's a significant shift in confidence.
This isn't just about investment strategy. Some are voting with their feet. The IRS recorded approximately 4,820 high-net-worth individuals renouncing U.S. citizenship in 2024, a 48% increase from 2023. High-profile figures like George Clooney have relocated their families overseas, seeking safety, privacy, and a different pace of life.
The trend extends beyond billionaires. The number of "everyday millionaires" has quadrupled since the start of the millennium, reaching nearly 52 million by the end of 2024. Even as wealth creation accelerates, perceptions about where to build and preserve that wealth are changing.
Now, before you write off America entirely, the country still leads in wealth creation. The U.S. produced 92 new self-made billionaires in 2025, generating $179.9 billion in fortunes from American innovation. That's more than any other country. And when UBS surveyed billionaires about long-term investment destinations, 65% still ranked North America as the top spot.
So what gives? The disconnect between short-term pessimism and long-term optimism among the ultra-wealthy suggests something more nuanced than a simple exodus. While North America remains a preferred destination for capital, the growing trend of wealth migration could reshape future investment patterns and economic growth trajectories.
For the U.S. to maintain its position as the premier destination for the world's wealthiest individuals and their capital, addressing whatever's driving this shift in sentiment will be crucial. Because when billionaires start looking elsewhere, even temporarily, it's worth paying attention to why.
