Amazon founder Jeff Bezos is now worth $150bn (£113bn), according to the Bloomberg Billionaire Index.
Jeff Bezos's net worth has increased by over $60bn in the last 12 months, which makes him the world's richest man.
This places his worth higher than that of Microsoft co-founder Bill Gates, who has previously topped the rich lists - even at his peak in 1999. Then Gates was worth $100bn - which would be around $149bn today, when adjusted for inflation. Gates is currently in second place with a worth of $95bn.
It's not the first time Jeff Bezos has topped the world's rich list - in July 2017, he briefly overtook Bill Gates to become the world's richest man according to Forbes when Amazon's shares surged - but returned to second place when their value dropped again.
