The numbers are genuinely staggering, and the consulting firm that produces the most comprehensive annual accounting of global wealth made sure you'd hear them: 25.3 million people on earth now hold $1 million or more in investable assets, a jump of nearly 2 million in a single year. Total high-net-worth wealth hit $98.3 trillion in 2025 — an 8.7% increase year over year and the largest single-year gain since 2018. The United States alone minted roughly 736,000 new millionaires, the fastest clip since 2021. The headline practically writes itself: the AI boom is making people rich.

It is. Just not most people.

The mechanism is straightforward and worth saying plainly: stock market gains drive roughly two-thirds of high-net-worth wealth growth. Wealthy Americans, who already had larger equity positions than their peers, increased their equity allocations by approximately five percentage points last year — from roughly 22% to 27% of their portfolios — precisely as AI-related stocks were surging. The bet paid off in extraordinary fashion. The S&P 500 top 10 holdings now represent 40% of the entire index's weight, dominated by a short list of AI-adjacent megacaps — Nvidia, Microsoft, Alphabet, Apple, Amazon, Meta, and Tesla among them — that accounted for more than half of the benchmark's total 2025 return, according to Goldman Sachs's own equity research. The rally was real. It was also extraordinarily narrow.

Here is the number that doesn't make the wealth-management press releases: the bottom 50% of American households own approximately 1% of all corporate equities and mutual fund shares, according to Federal Reserve flow-of-funds data. The wealthiest 1% own 50% of stocks — roughly $29 trillion worth as of late 2025. The top 10% control 87% of all equity wealth. This is the arithmetic behind the millionaire boom: when the stock market rises 20%, the people who own almost all of it get almost all of the gains. Everyone else gets the vibes.

The geographic picture is equally clarifying. North America was the decisive winner, its high-net-worth population rising 7.3%. Europe lost ground — the United Kingdom shed 14,000 millionaires, France 21,000, Germany 41,000 — as a stronger dollar and sluggish domestic equity markets eroded local wealth. Latin America fared worse still, its high-net-worth population declining 8.5% as currency depreciation and fiscal instability hammered portfolios. The Middle East contracted too. AI wealth is American wealth, for now, concentrated in jurisdictions that happen to house the companies whose valuations are doing the minting.

Inside the already-rich, the internal stratification is sharpening. Ultra-high-net-worth individuals — those with $30 million or more — grew their ranks by 9.4% and their collective fortunes by 9.7%, outpacing even the broader millionaire class. That 1% sliver of the high-net-worth universe controls 34% of total high-net-worth wealth. So the rally is minting new millionaires, yes, while simultaneously making the centi-millionaires and billionaires richer at a faster clip than those newly minted millionaires. Wealth accelerates at the top of the distribution regardless of market conditions; a bull market just turns up the speed.

The wealth management industry, which exists to service this class, is confronting its own awkward reckoning. Despite overseeing a record pool of assets, firms are losing clients faster than the asset growth implies they should be. According to the same Capgemini data, 97% of wealth management firms still segment their clients primarily by the size of their bank account rather than by their actual goals, needs, or values. Only 17% of high-net-worth investors describe their advisory experience as both seamless and personalized — and 42% report having to re-explain their financial goals to the same firm more than once. The industry is, in other words, getting richer while annoying its customers. That's a structural problem no bull market fixes.

The deepest tension in this story is one that never appears in the Capgemini press release. The AI rally is conjuring wealth by inflating the valuations of companies whose technology is, simultaneously, reducing demand for the kind of labor that allows ordinary workers to build savings in the first place. Stanford economists tracking early-career workers in the most AI-exposed jobs have found a 13% relative employment decline in that cohort. The stock market gains and the labor-market disruption share the same source. What the equity markets give to those who own them, the productivity revolution can take from those who don't.

None of that is hidden. It is in the Federal Reserve data, in the market concentration reports, in the labor studies. The millionaire count is a real number. So is the 1%. Both belong in the same sentence.
