WASHINGTON - As Amazon marked its Prime Day with price cuts across a range of products, founder and chief executive Jeff Bezos saw his net worth hit new peaks, increasing his lead over fellow billionaires.
Bezos's net worth topped US$150 billion (S$205 billion) on Monday (July 16), according to the Bloomberg Billionaires Index, making him the world's richest person in decades.
The surge in the share price for Amazon - in which Bezos holds a stake of some 16 per cent - has lifted his wealth by some US$50 billion this year.
And Bezos has moved into a wealth category all by himself, far ahead of Microsoft founder Bill Gates, worth an estimated US$95 billion, according to the Bloomberg ranking.
Gates saw his net worth briefly hit US$100 billion in 1999, but since then, Bezos appears to be the only person to top that milestone.
Historically, Bezos still trails other wealthy individuals such as oil magnate John D. Rockefeller and steel baron Andrew Carnegie, whose inflation-adjusted net worth would be more than US$300 billion.
Yet his rise has been nothing less than spectacular since 2014 when his fortune was estimated at around US$32 billion.
