Facebook has been valued at $33.7bn (£22bn) - which is higher than eBay and Yahoo - ahead of its expected initial public offering (IPO) of stock.
Based on how much initial investors are selling their private stakes for, the Financial Times reported common stock is trading as high as $76 a share.
While Facebook is unlikely to sell stock through an IPO until 2012, investors are acquiring stakes in the social network while its still private in the hope that an IPO will boost share prices further, said the FT.
According to analysts, a Facebook IPO may attract the same high level of attention as Google's share sale in 2004.
The price of Facebook stock jumped 42% from July to November last year, with shares selling on private exchanges at around $21 each, putting the value of common shares at $9.5bn.
