In news reported by my colleague Tomio Geron yesterday, publicly-traded closed-end mutual fund GSV Capital (nasdaq GSVC) bought 225,000 shares of the social networking giant Facebook at an average price of $29.28 per share or a valuation of about $70 billion. Its stock is up about 40% since the news.
The $70 billion valuation is also a 40% premium to the $50 billion we used to measure the fortunes of the six Facebook billionaires back in February when we were putting together our list of World’s Richest People. Its shares have traded even higher on secondary markets.
At the time we valued Facebook’s chieftain Mark Zuckerberg’s net worth at $13.5 billion. Today, based on the new numbers, Zuckerberg’s mostly paper fortune (we figure he has quietly sold about $1 billion worth of shares) jumps past $18 billion. The other Facebook billionaires including Dustin Moskovitz, Eduardo Saverin, Sean Parker, Peter Thiel and Yuri Milner are all richer too.
