"Shareholder trading values Facebook at more than $33bn" The Guardian--August 25, 2010: This reference does not confirm Thiel's percentage stake, implied to be 5.2% i.e. 33 divided by 1.7. The 5.2% is also independently asserted in the Facebook section of this Wikipedia article, but without citation. The imputed valuation of Facebook has, also, moved up to $50bn in an early-2011 transaction with Goldman Sachs (Craig, Susanne and Andrew Ross Sorkin, "Goldman Offering Clients a Chance to Invest in Facebook", The New York Times Dealbook, January 2, 2011, 11:31 pm ET.) A 5.2% share of $50bn would be worth $2.58bn. For its part, by March 2010, Forbes had actually reduced its estimate of Thiel's net worth to $1.2bn (#828 on list of world's billionaires), though the higher Facebook valuation makes this even more undervalued. Footnote expanded 2011-01-11.
