Mega-Rich Got So Much Richer During Pandemic the English Language Didn't Have a Word to Describe Them
The word “billionaire” didn’t even exist until 1844. Fifty years later, we got “multibillionaire,” and for the next 127 years, that was enough. But in 2020, the rich got so much wealthier, we needed a new word: “centibillionaires.”

The word “billionaire” didn’t even exist until 1844. Fifty years later, we got “multibillionaire.” And for the next 127 years, that was enough.
But in 2020, while the working class faced near-record unemployment during the COVID pandemic, the wealthiest Americans faced a different problem. Some of them had gotten so rich, there was no longer a word to describe just how rich they were.
That’s why I want to bring you one of the newest additions to the English language: “centibillionaires,” people with $100 billion or more.
What’s it like being one of history’s first centibillionaires? It’s hard to even imagine, but let’s try it by comparing them to the less fortunate. By which I mean just … regular … billionaires.
