Amazon's Jeff Bezos first after Bill Gates to have net worth of $100 Bn

Jeff Bezos, the world’s richest man, saw his net worth exceeding $100 billion on Friday after the company’s shares jumped more than 2 percent on optimism for Black Friday sales.

The online sales on Black Friday rose by 18% from last year, according to data from Adobe Analytics.

This is the second time when any billionaire’s wealth has crossed the 12-digit figure after Microsoft’s Bill Gates who touched the mark in 1999.

In July this year, Bezos' net worth topped $90 billion and he became the world’s richest man. He dethroned Gates for a brief period of time as an afternoon dip in Amazon's stock price caused Bezos to end up with $88.8 billion.

Last month, Bezos emerged as the clear winner in the world’s richest race when he left Gates behind some billion of dollars.

Bezos’ fortune rose $32.6 billion this year, the largest increase ever observed in a year. Amazon have climbed 5 percent this week alone.

Besides Amazon’s Jeff Bezos, Alibaba’s Jack Ma is another e-commerce player who is gradually rising in the billionaire list.

According to Bloomberg Billionaires Index, Alibaba’s founder net worth climbed $8.5 billion this year to $41.8 billion. The sales growth of his company topped every analyst’s estimate in spite of China's decelerating economy. Alibaba has ventured into new areas from cloud computing services to streaming music and video.

The company has captured more digital advertising spending by incorporating social elements such as video in its shopping sites.
