Facebook CEO Mark Zuckerberg surpassed the Oil magnets Charles and David Koch to become the sixth wealthiest person in the world. His company’s stock soared 13% on Thursday which made him become one of the richest persons in the world. Mark Zuckerberg earned a cool $1.6 billion in a single day, putting his new net worth at $33.3 billion.

These earnings beat street estimates, resulting in the rise in shares. The social networking company reported a 52% rise in fourth-quarter sales on Thursday while its net income saw a two-fold increase to $1.56 billion. As most of Zuckerberg’s fortune is tied to his holdings in Facebook, the stock price increase made him richer by $6 billion in one day.

Now the 31-year-old Facebook CEO is now worth $47.9 billion. The only people wealthier than Zuckerberg, according to Bloomberg data, are: Microsoft co-founder Bill Gates ($78 billion), Zara founder Amancio Ortega ($69.7 billion), the Oracle of Omaha Warren Buffett ($59.4 billion), Amazon founder & CEO Jeff Bezos ($55.8 billion) and telecom magnate Carlos Slim Helu ($47.5 billion).
