Jeff Bezos, the founder of online retail giant Amazon, is now the fourth richest person in the world, according to Bloomberg.
The retail leader overtook Mexico’s Carlos Slim after Amazon’s (AMZN) stock price skyrocketed this year.
The latest increase in Amazon’s stock value means Bezos is now worth $58.2 billion according to Bloomberg’s index of world billionaires. Slim, meanwhile, is only worth $57.2 billion. Slim’s worth has fallen by around $15 billion this year.
The three people above Bezos are Microsoft (AMZN) co-founder Bill Gates, Spanish clothing retailer Amancio Ortega, and billionaire investor Warren Buffett.
This isn’t the only wealth list Bezos has climbed this year, Bloomberg notes. He also recently passed Charles and David Koch—leaders of Koch Industries and notorious Republican Party donors—to clinch third place on Bloomberg’s list of the richest people in the United States, coming in behind Gates and Buffett.
Amazon’s share price has risen 116% this year, climbing from around $310 a share to around $670 a share.
