There are only 15 people on the earth with 12-figure fortunes of $100 billion or more, Fortune reports. Most of them made their vast amounts of money in technology.

Combined, their wealth is worth $2.2 trillion, more than the $2 trillion market capitalization of Google parent Alphabet and Amazon’s $1.8 trilllion.

Topping the list is Elon Musk, who has amassed an estimated net worth of $245 billion through his myriad of companies including Tesla, X, SpaceX, Boring and Xai, according to the Bloomberg Billionaires Index.

Jeff Bezos is the second-richest person on the earth, having made his fortune by founding online retail powerhouse Amazon.com.

Bernard Arnault, CEO and founder of luxury goods maker LVMH is the third-richest person in the world.

Only two European centibillionaires make the cut: Arnault and Amancio Ortega, the Spanish founder of the Inditex fashion group, which owns Zara, Massimo Dutti, and Berksha.
