It was gathered that Bezos' fortune went up $2.4 billion to $100.3 billion, as the online retailer's shares jumped more than 2 percent on optimism for Black Friday sales.
According to the analysts, the online spending shoots up 18.4 percent over the last year and the remaining festive days of the year will continue to boost the online purchases.
It also makes him the most recent person to rack up a 12-figure fortune since Bill Gates managed the milestone nearly two decades ago, in 1999. Bezos's fortune grew tremendously this year and on Thursday, registered the highest surge, accumulating $32.6 billion to his name as shown onBloomberg Billionaires Index, the daily ranking of World's 500 richest people.
Mr Bezos started Amazon in his basement in Seattle 22 years ago, after he quit his job as a hedge fund manager in NY.
Topping $100 billion makes Bezos the first billionaire to amass a 12-figure fortune since Microsoft co-founder and philanthropist Bill Gates achieved the feat in 1999. Investor Warren Buffett is third at around $78.9 billion. That said, Gates has given a significant amount of his fortune away to charity and in acts of philanthropy.
Gates, who now has a net worth of $86.8 billion, is estimated to have had a net worth of $150 billion had he not given so much of his fortune to charity. Over the summer, he tweeted a request for short-term philanthropic ideas aimed at helping people in the here and now.
