Already the richest Jewish person in the world, Zuckerberg, 31, has a net worth of $47.5 billion. That puts him slightly ahead of the Koch brothers, whose fortune stands at $45.9 billion, Bloomberg Business reported last week.
The Facebook CEO moved past Charles and David Koch last Thursday. His fortune rose $6 billion in trading when Facebook reported record earnings that day. Zuckerberg was number eight on the Bloomberg index last October.
Bill Gates, Amancio Ortega, Warren Buffett, Jeff Bezos and Carlos Slim are the top five on the index.
Among Jews, Zuckerberg is ahead of Oracle’s Larry Ellison, who is number 10 overall.
Zuckerberg and his wife, Priscilla Chan, announced plans last December to donate 99 percent of their Facebook shares to charity over their lifetimes.
