Amazon founder Jeff Bezos has become the world's richest person after soaring Black Friday sales and a banner year for his company. Bezos would be the first billionaire to pass the $100-billion mark since 1999, when Microsoft's Bill Gates accomplished the same. Earlier this year, Bezos overtook Gates as the world's richest person.
In fact, the 62 year-old founder of Microsoft would would be worth more than $150 billion (£112.4bn) if he hadn't donated nearly $700 million (£524.91m) Microsoft Corp. shares and $2.9 billion (£2.17bn) of cash and other assets to charity since 1996.
Bloomberg says Bezos fortune now totals $110.3 billion.
At the beginning of the year, Bezos cracked the top four, surpassing Inditex founder Amancio Ortega and US investor Warren Buffett at the time.
The increase, to $100.3bn, is thanks in part to the clamour for Black Friday deals - Amazon shares have gone up 5% this week alone. He also owns the Washington Post, which he purchased for $250 million in 2013, and he owns shares in a number of other companies.
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.
Unlike Gates and Buffett, Bezos has given relatively little of his fortune to charitable causes.
Bezos started Amazon as a well to sell books online, and now Amazon's stature among investors reflects its growing dominance in the retail world, where it accounts for roughly a third of all e-commerce transactions, and its ambitions to push into other sectors of the economy.
But Mr Bezos has to date has not given away any of his wealth, but in June he tweeted that he wanted the help people with his fortune and was looking for ideas for how to share it.
