(JTA) — Facebook founder Mark Zuckerberg, the richest Jewish person in the world, has become the sixth-wealthiest overall.

Zuckerberg, 31, has a net worth of $47.5 billion, according to the Bloomberg Billionaires Index, slightly ahead of the Koch brothers’ fortune valued at $45.9 billion, Bloomberg Business reported last week.

He moved past the Kochs when his fortune rose $6 billion in trading Thursday, when Facebook reported record earnings. In October, Zuckerberg was listed No. 8 on the Bloomberg index.

In December, Zuckerberg and his wife, Priscilla Chan, announced plans to donate 99 percent of their Facebook shares to charity over their lifetimes.
