Jeff Bezos added $13 billion to his net worth on Monday, July 20, the largest single-day jump for an individual since the Bloomberg Billionaires Index was created in 2012.

Amazon.com shares surged 7.9%, the most since December 2018 on rising optimism about web shopping trends, and are now up 73% this year, according to TIMES.

Bezos, 56, who is the world’s richest person, has seen his fortune swell $74 billion in 2020 to $189.3 billion, despite the U.S. entering its worst economic downturn since the Great Depression during the 1930s.

According to the publication, the American Billionaire is now personally worth more than the market valuation of giants such as Exxon Mobil Corp., Nike Inc., and McDonald’s Corp.

Jeff’s ex-wife, Mackenzie Bezos, who is Amazon’s second-largest individual shareholder, following her divorce from the Amazon CEO also gained $4.6 billion Monday and is now the 13th-richest person in the world. She is worth over $55 billion.
