NO

While measurements of net worth are inexact, there are individuals widely believed to have possessed more wealth than Elon Musk, whose net worth, derived from the value of companies he helped build, peaked at $340 billion in November 2021, according to Bloomberg.

Ancient rulers form the bulk of those wealthier than Musk. Roman emperor Augustus Caesar, whose control of powerful states allowed him to amass personal riches, may have had a net worth as high as $4.6 trillion. Mansa Musa, who ruled the gold-rich Mali Empire in the early 1300s, possessed an estimated $415 billion. Visual Capitalist notes these are rough figures given the difficulty of valuing historical wealth in current U.S. dollars.

In the modern world, oil magnate John D. Rockefeller amassed as much as $400 billion, according to Investopedia. This estimate is a measure of net worth as a percentage of GDP.

This fact brief is responsive to conversations such as this one.

Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs.
