Zuckerberg’s Stake Worth $28.4B at Highest Range

Facebook Inc. (FB)’s initial public offering, heralded in a regulatory filing today, is poised to widen the ranks of the world’s billionaires.

Chief Executive Officer Mark Zuckerberg, 27, is the biggest stakeholder in the company as it prepares to go public, with 28.4 percent ownership, while investment firms Accel Partners and Digital Sky Technologies own a combined 16.8 percent.

Zuckerberg, who started Facebook in his Harvard University dorm room in 2004, owns 533.8 million shares of the largest social network, according to a filing with the U.S. Securities and Exchange Commission. Co-founder Dustin Moskovitz, whose work on the company was depicted in the Oscar-winning 2010 film “The Social Network,” owns 133.8 million shares, or 7.6 percent.

Facebook said in its prospectus that it plans to raise as much as $5 billion in an initial public offering. The company is discussing a valuation of $75 billion to $100 billion, two people familiar with the matter said last week. Assuming the Menlo Park, California-based company is valued at the top end of the range, Zuckerberg will own stock worth $28.4 billion.

By comparison, Google Inc. co-founders Sergey Brin and Larry Page are each worth more than $15 billion based on their ownership of that company’s shares. Larry Ellison owns stock worth about $31 billion in Oracle Corp., the software company he founded in 1977.

Facebook Chief Operating Officer Sheryl Sandberg owns 1.9 million shares, or 0.1 percent. Peter Thiel, who provided a seed investment for Zuckerberg in 2004, owns 44.7 million shares, or 2.5 percent.
