Many of the world's richest people have seen their wealth balloon since this year during the coronavirus pandemic. Per Bloomberg, the richest 500 people have made a cumulative gain of $809 billion. Musk's wealth has increased by more than $73 billion since January, according to the Bloomberg Billionaires Index, and Bezos' by $87 billion.

Musk's wealth increase largely comes down to Tesla's stock soaring 400% this year. As of June, Musk owned 40.4 million Tesla shares, which would account for $87 billion of his net worth. At the beginning of 2020, Musk owned roughly 38.7 million shares, worth $16.2 billion.

In May, Musk also hit the first in a series of executive milestones meant to eventually allow him to unlock a $55 billion bonus package. The first milestone allowed him to unlock one of 12 "tranches" of stock options.

Besides Musk and Bezos, just two other people have a net worth above $100 billion: Bill Gates, worth $124 billion, and Mark Zuckerberg, $115 billion.
