Zuckerberg richer than Google guys after stock rally

While Facebook and Google duke it out for Internet ad dominance, Facebook CEO Mark Zuckerberg has already beaten Google co-founders Sergey Brin and Larry Page in one key metric — net worth.

The 30-year-old Zuckerberg added $1.6 billion to his personal fortune on Thursday after the world’s largest social network closed at a record high, fueled by blowout second-quarter results.

The gains pushed his net worth on paper to $33.3 billion, catapulting Zuckerberg past Brin, 40, and Page, 41, as well as Amazon boss Jeff Bezos, 50, according to the Bloomberg Billionaires Index.

Zuckerberg is now the 16th-richest man in the world, while the Google founders occupy the 17th and 18th spots. Bezos checks in at No. 20 on the list.

The Menlo Park, California-based company recorded second-quarter sales that jumped 61 percent, to $2.91 billion — surpassing analysts’ average estimate of $2.81 billion — thanks to Facebook’s robust mobile ad business.

Facebook shares, which topped $75 on Friday, are trading at almost twice the $38 price set for its initial public offering two years ago.

The stock has soared 183 percent in the past 12 months, the biggest rally in the S&P’s 500 Index, while Google is up only 7.5 percent for the year.
