Jeff Bezos has a lot to be thankful for after this year's Thanksgiving. 

The Amazon.com Inc. (AMZN) CEO is now worth more than $100 billion after a record-setting online shopping weekend kicked off the holiday retail season. That puts him ahead of the previous leader, Microsoft Corp. (MSFT) co-founder Bill Gates, who is worth $89.1 billion.

Early Monday, Bezos was worth $99.6 billion, according to Forbes. By the opening bell, Bezos surpassed the $100 billion mark, according to the Bloomberg Billionaires Index.

Bezos made almost $2.4 billion on Black Friday alone. His 78.9 million shares of Amazon are worth about $95 billion Monday, and that's not taking into account any wealth accumulated from his ownership in space exploration company Blue Origin or in the Washington Post. 

Adobe Analytics found that Black Friday and Thanksgiving Day online sales jumped 17.9% over last year to a record $7.9 billion for 2017. The firm forecasts Cyber Monday, on Nov. 27, could become the largest U.S. online shopping day ever with $6.6 billion in total sales.

Amazon is expected to capture 50% of all online sales growth Monday, according to Bain & Co.

Amazon stock increased 1.8% to $1,206 just after the market open Monday. Since the start of the year, Amazon stock is up about 61%. During the same time, Bezos' wealth has increased 53%.
