According to Forbes, Amazon.Com IncShares closed up 1.2% on Tuesday, boosting the value of the company's founder and CEO Jeff Bezos by $2.2 billion to a record $199.7 billion, close to becoming the world's first $200 billion billionaire.

Note: Bezos was worth more than $200 billion in intraday trading on Monday, but the value of the rich on the Forbes list is based on the recent closing share price.

Because Mr Bezos owns 11.1 per cent of Amazon.Com Inc and the company has a market capitalization of $1.68 trillion, any small fluctuation in the share price could increase or decrease his worth by billions of dollars.

Amazon.Com Inc's share price has risen more than 55 per cent since the outbreak began in mid-February, thanks to a surge in demand for online shopping under home quarantine orders. Mr Bezos's wealth has risen by nearly $86 billion in less than a year, and when Forbes released the US 400th rich list last October, he was worth $114 billion, based on Amazon.Com Inc's share price in early September.

If he hadn't divorced his ex-wife Mackenzie, Bezos would have been worth more than $200 billion. In July last year, Bezos and Mackenzie divorced and gave her about 4 per cent of Amazon.Com Inc.
