Facebook is offering about 337.4 million shares for $28 to $35 each, according to a regulatory filing. At the upper end of that range, the co-founder’s stake would be $17.6 billion, making him richer than Microsoft Corp.’s Steve Ballmer and Russian steel billionaire Vladimir Lisin, who are both twice his age, according to the Bloomberg Billionaires Index.
Zuckerberg, who began the service for Harvard classmates as a 19-year-old in his dorm room, built Facebook into the most popular social-networking site in the world, topping 900 million users last quarter. Now he has to prove he has the leadership skills to deliver enough growth to justify the company’s valuation, said Paul Saffo, managing director at Discern Analytics in San Francisco.
