“Facebook founder Mark Zuckerberg’s net worth is now at its lowest since his company’s May 17 initial public offering, as the company’s shares hit a new low on Thursday. Facebook shares sagged 6.3 percent as it put millions more up for sale; the day’s drop personally cost Zuckerberg $600 million. His net worth is now down to $10.2 billion, according to Bloomberg, while other Facebook founders have also lost big. Chris Hughes, the new owner of The New Republic, lost $400 million since the IPO, Dustin Moskovitz $2.4 billion, and Eduardo Saverin, $960 million.”
OUCH. Those co-founders have each lost nearly half of their net worth.
