Facebook CEO Mark Zuckerberg has passed Charles and David Koch to become the sixth richest person on the planet, according to the Bloomberg Billionaires Index.

No, Zuck didn't win the Powerball. Facebook reported record revenue on Wednesday during its fourth quarter earnings call, thanks largely to mobile growth.

That boosted Zuckerberg's net worth by $5.5 billion to a new grand total of $47 billion — placing him ahead of the Koch brothers, who are currently worth $45.3 billion, according to Bloomberg. Zuckerberg still has some work to do to crack the top five.

Bill Gates ($77.9 billion) Amancio Ortega ($70.2 billion) Warren Buffett ($59.1 billion) Jeff Bezos ($51.9 billion) Carlos Slim ($47.1 billion)

Zuckerberg has promised to give most of his fortune away through the Chan Zuckerberg Initiative, a private limited liability company (LLC) he set up with his wife, Priscilla Chan, to fund philanthropic causes, lobby for political change, and invest in companies.

One place Zuckerberg isn't spending money is on a personal stylist. On Monday, Zuckerberg announced he was returning from paternity leave after the birth of his daughter, Max, with a post showing off his monochromatic wardrobe.
