The richest sliver of American society, a group so small it rounds to zero, now commands 12% of US national income. We’re talking about roughly 19 to 34 households. They’d control more wealth than most countries produce in a year.

Research from economists Gabriel Zucman and Emmanuel Saez puts this figure at three times the concentration seen during the peak of the Gilded Age in 1910, when the equivalent elite held about 4%.

The numbers behind the superlative

The collective wealth of America’s top 0.00001% reached approximately $2.6 trillion by the end of 2024. This group added about $1 trillion in wealth in a single year.

Their share of total US household wealth climbed from 0.1% in 1982, when the group numbered just 11 households, to 1.8% by the end of 2024. That’s an 18x increase in share over roughly four decades.

How we got here

The post-1980s era reshaped the mechanics of wealth accumulation in the US. Stock market surges, enhanced corporate valuations, and a tax environment increasingly favorable to capital over labor created the conditions for this kind of extreme concentration.

The data, drawn from distributional financial accounts and tax records, paints a picture of how the extreme tail of wealth distribution evolved. Zucman and Saez have been tracking this trend for years, and the trajectory has been remarkably consistent: up, and to the right, at an accelerating pace.

What this means for investors and markets

The absence of any meaningful crypto or digital asset allocation in the coverage of these ultra-wealthy households is notable. It suggests that, at the very top of the wealth pyramid, conventional asset classes, equities, private markets, real estate, remain the primary vehicles for wealth accumulation.
