Mark Zuckerberg is in position to overtake Jeff Bezos as the world's fifth richest person.
After Facebook's strong earnings report this week, the value of Zuckerberg's 428 million shares soared by more than $7.3 billion, and are now worth close to $48 billion.
Meanwhile, on the back of weaker-than-expected earnings, the value of Bezos' 83 million Amazon shares plunged by more than $3.7 billion, making them worth nearly $49 billion. Which means, purely in terms of stock ownership in their respective companies, Zuckerberg is less than $1 billion from overtaking Bezos on the billionaire list.
Of course, Bezos has a number of other assets contributing to his total net worth. Forbes' real-time index puts his net worth at $51.6 billion. Meanwhile, the Bloomberg billionaires ranking pegs Bezos' wealth at $55.8 billion.
It's unclear how much of the stock moves are baked into either ranking, since they are as of Thursday, and both still have Bezos at No. 4.
