How the World’s Richest Person Changed Over 40 Years
Key Takeaways
- Bill Gates held the title of world’s richest person in 18 of the 40 Forbes lists since 1987, including 13 consecutive years.
- Yoshiaki Tsutsumi ranked first in six of the first eight annual lists, reflecting the scale of Japan’s real estate fortunes in the late 1980s and early 1990s.
- Elon Musk’s 2026 fortune reached levels far beyond earlier inflation-adjusted records, with Forbes estimating his wealth at $923 billion in September.
Over the last 40 years, the title of world’s richest person has shifted from Japanese real estate tycoons to U.S. tech billionaires.
The progression also reflects a broader shift in the sources of extreme wealth. Microsoft, telecom, e-commerce, luxury goods, and more recently electric vehicles and space technology have each produced the world’s largest fortunes.
The data for this visualization comes from Forbes’ World’s Billionaires lists. Historical net worth estimates have been adjusted for inflation using U.S. CPI data, while the 2026 figure uses a real-time Forbes estimate from September 2026.
Because billionaire wealth is closely tied to asset prices, these estimates can move dramatically even over short periods. Forbes’ annual 2026 list, for example, valued Elon Musk at $839 billion using prices from March, while its real-time tracker placed his fortune at $923 billion in September.
Bill Gates Dominated the Rankings for More Than a Decade
Bill Gates appears at the top of this 40-year dataset more often than anyone else. The Microsoft co-founder ranked first in 18 annual lists, including an uninterrupted 13-year stretch from 1995 through 2007.

Japan’s Real Estate Fortunes Ruled the Early Years
Yoshiaki Tsutsumi ranked first in six of the eight annual lists from 1987 through 1994, while real estate magnate Taikichiro Mori took the top spot in 1991 and 1992.
Tsutsumi’s inflation-adjusted fortune stood at roughly $58 billion in 1987. These fortunes were closely associated with Japanese property and real estate holdings during the country’s late-1980s asset boom.
Tsutsumi built his fortune through the Seibu business empire, which included extensive railway and real estate holdings across Japan. At his peak, he controlled one-sixth of Japan’s land.
By 1995, Gates had moved into first place, marking the beginning of a major shift in the source of the world’s largest fortunes—from property toward technology.
Elon Musk Pushes Billionaire Wealth Into New Territory
More recently, the scale of wealth at the top has accelerated sharply. Jeff Bezos became the world’s richest person for four consecutive annual lists from 2018 to 2021, with his inflation-adjusted fortune reaching about $215 billion in 2021.
Musk reached $246 billion in 2022, while Bernard Arnault and his family took the No. 1 position in 2023 and 2024. Musk returned to the top in 2025 and remained there on Forbes’ 2026 annual list.
Forbes valued Musk at a record $839 billion for its March 2026 list, more than three times the $257 billion fortune of second-ranked Larry Page.
His wealth has also proved volatile. Forbes reported that it briefly reached $1.45 trillion in June following SpaceX’s public listing before subsequently falling.
Musk also ranks as the world’s highest-paid CEO. In 2025, his total compensation reached $132.3 billion, driven by a long-term Tesla stock award tied to ambitious market capitalization and operating targets.
