Bill Gates has unseated Amazon CEO Jeff Bezos for the top spot of world's richest people.
Gates, the co-founder of Microsoft has a net worth of US$110 billion ($171.7b), which currently tops Bezos' US$109b, according to the Bloomberg Billionaires Index.
It's the first time Gates has held the top spot in over two years, according to CNN.
According to Bloomberg Billionaires Index, Gates has added US$19.5b to his fortune so far this year, while Bezos has lost US$16.2b.
Gates' rise to the top has been spurred by a 48 per cent increase in Microsoft shares this year.
Bezos' wealth has been impacted by his divorce from wife of 25 years MacKenzie. MacKenzie is due to keep 25 per cent of the couple's Amazon stock (a 4 per cent stake in the company) worth roughly US$35.7b, according to a securities filing in April.
