It was the most significant single-day increase in personal wealth since the index started in 2012, Bloomberg reported, after analysts raised their targets for Amazon's stock, which jumped 7.9 percent Monday, ahead of the company's second-quarter earnings report.
So far this year, his wealth grew by a total of $74 billion to more than $189 billion, according to the index.
Amazon's stock has swelled 73 percent year-over-year. The e-commerce giant has seen an unprecedented boom in business since the coronavirus pandemic started as more people began shopping from home, particularly as stay-at-home orders were implemented by local governments.
Amazon temporarily delayed orders for nonessential items in March and April due to a surge in orders for cleaning products, personal protective equipment and other coronavirus-related products.
Bezos' personal wealth is now more than some of the most valuable companies in the world, including Wells Fargo, Costco and Oracle.
The Amazon CEO became the wealthiest man in modern history in 2018; Microsoft founder Bill Gates' net worth briefly surpassed Bezos' in October 2019 after Amazon's stock took a steep fall, but his worth has since remained on top.
