The Richest People Of All Time – Inflation Adjusted

By on April 14, 2014 in ArticlesEntertainment

Back in 2010, Celebrity Net Worth published a list of the richest humans in history, adjusting for inflation. That original list, which was published right here on this URL, spawned countless copycat versions, wikipedia pages and clickbait galleries. It was referenced in songs, books, podcasts and television series. We spent a month compiling that first list. It was the first major long-form article (non net worth estimate) that we published.

To compute historical fortunes into modern present-day net worths, we used a combination of basic inflation calculations, the relative purchasing power of wealth to GDP over time, and finally, the historical value two primary assets: gold and land. We started with over 100 historical and present-day figures who were known to be exceptionally wealthy. Business tycoons, kings, queens, emperors, landowners, tyrants… We ended with 25 individuals. Those 25 individuals were the richest people of all time, at that point.

A lot has changed since 2010. In our original list, Warren Buffett's then-peak $64 billion net worth was enough to make him the 25th richest person in history. Today $64 billion would barely be enough to make you one of 25 richest richest people on the planet right now!

In 2010, Facebook was two years away from being a public company. At that point, the company's 26-year-old founder Mark Zuckerberg, was worth around $5 billion on paper based on Facebook's most recent private valuation. In September 2021, Mark's net worth peaked at $140 billion.

In 2010, a $100 billion fortune was extremely significant. Only a handful of people had ever produced a net worth greater than $100 billion, even after adjusting for inflation. Today people don't even blink at a $100 billion fortune. In July 2021, all 10 of the richest people in the world had net worths exceeding $100 billion. Even $200 billion has become somewhat unremarkable.

Perhaps most amazingly of all, our 2010 list did not feature the following two names:

Back in 2010, Jeff Bezos was worth an extremely respectable, but not exactly earth-shattering, $20 billion. Thanks to Amazon's incredible growth in the last decade, Jeff Bezos slowly and steadily established one of the largest personal fortunes in history. And that's true even after losing a sizable chunk of that fortune to his ex-wife.

And then there's Elon.

In the last decade, no billionaire has seen a more extreme explosion in wealth than Elon Musk. By total coincidence, we published our original 2010 list just a few weeks before a very important event in wealth history: On June 29, 2010, Tesla went public.

Tesla ended its first day of trading as public company with a total market cap of $1.77 billion. That is not a typo. $1.77 billion.

In November 2021, Tesla's market cap hit $1.2 trillion. At that level, thanks additionally to the increased valuation of his other company, SpaceX, Elon's net worth hit a truly historic level.  To find out just how historic, you'll have to keep reading…

Who is the Richest Person In History?

Mansa Musa I –  $400 Billion

Mansa Musa I of Mali is the richest human being in history with a personal net worth of $400 billion! Mansa Musa lived from 1280 – 1337 and ruled the Malian Empire which covered modern day Ghana, Timbuktu and Mali in West Africa. Mansa Musa's shocking wealth came from his country's vast production of more than half the world's supply of salt and gold. Musa used his wealth to build immense mosques that still stand today, nearly 700 years later. His kingdom and wealth didn't last much longer after his death. His heirs were not able to fend off civil war and invading conquerors. Just two generations later, his world record net worth was gone.

The Rothschild Family – $350 Billion

The Rothschild family are the richest people on earth today with assets that total at least $350 billion. Their net worth is difficult to peg because their holdings are so vast, but without question they are the most powerful family in the world. Many people believe they control over $1 trillion in real estate and banking assets alone.

Elon Musk – $341 billion

On November 4, 2021, with Tesla's stock price soaring to an all-time high, Elon Musk's net worth briefly topped $341 billion. For several hours that day, Elon was officially worth more than John D. Rockefeller's inflation-adjusted wealth record of $340 billion which hstood for 80 years.

John D. Rockefeller –  $340 Billion

John D. Rockefeller is the richest American who ever lived. At the time of his death in 1937, Rockefeller was worth the equivalent of $340 billion in today's dollars. His company Standard Oil dominated American Oil production and was eventually broken up by The US Government for being a monopoly. Standard Oil was broken into smaller companies that you probably recognize today: Amoco, Chevron Conoco, and ExxonMobil. Rockefeller was the first American to ever have a net worth over $1 billion.

#4 Andrew Carnegie –  $310 Billion

Andrew Carnegie made his vast fortune when he sold his Carnegie Steel Company to JP Morgan for $480 million in 1901. That equates to a peak net worth equivalent to $310 billion in modern dollars. When he sold his company to JP Morgan, Carnegie took home $230 million worth of gold bonds and received a 5% annual coupon to top it off. The bonds sat in a bank in New Jersey which Carnegie never visited. After selling his company, Carnegie retired from business life and dedicated his time to charity. He gave away the majority of his fortune during his lifetime and his final $30 million was donated after his death. Many universities and foundations still bear his name today.
