Mark Zuckerberg is now richer than Google Inc. co-founders Sergey Brin and Larry Page, despite the company’s contentious IPO just 2 years ago with lead investment banker and brokerdealer Morgan Stanley.

According to Bloomberg, the Facebook Inc. chairman has added $2 billion (USD1.6 billion) to his fortune after the world’s largest social network closed at a record $74.98, and a rose further to $75.07 in after-hours trading.

The stock surge has pushed Zuckerberg’s net worth to $33.3 billion, taking him past Brin, 40, and Page, 41.

He has also surpassed Amazon CEO Jeff Bezos, 50, on the Bloomberg Billionaires Index.

The index ranks Zuckerberg at No. 16 now with the Google founders at 17th and 18th respectively. Bezos occupies the 20th spot.

“He’s just getting started,” David Kirkpatrick, author of “The Facebook Effect,” told Bloomberg in a telephone interview. “He’s going to become the richest person on the planet.”
