About This Ranking

Billionaires under 40 represent the fastest wealth-creation trajectories in modern economic history. For those in their 30s, accumulating a billion dollars in assets means having grown a business (or inherited one) at an extraordinary rate. Many on this list are tech founders who benefited from rapid user growth, early venture backing, and successful IPOs.

All net worth figures are estimated from publicly available data including SEC filings, stock exchange prices, and company financial reports. Rankings are updated daily. Read our full methodology.
