Mark Zuckerberg is now the world's fourth-richest person

Need a loan? Consider reaching out to Facebook founder Mark Zuckerberg, who just passed Amazon CEO Jeff Bezos to become the fourth richest person in the world.

Forbes estimates that Zuckerberg, as of Tuesday, is worth $50 billion, while Bezos is worth about $48.9 billion. Zuckerberg, 31, is making his way up the ladder fast — a year ago, he was 15th on the Bloomberg Billionaires Index. Zuckerberg has been propelled by Facebook's strong stock performance, which is up 9.5 percent in 2016.

If Zuckerberg wants to capture the top spot, he has a ways to go — Microsoft founder and philanthropist Bill Gates, estimated by Forbes to be worth $75.6 billion, currently holds the title.
