On Second Market, Facebook worth more than Yahoo

Facebook Inc. would reportedly be worth about $25 billion, higher than the $21 billion market cap of Internet giant Yahoo Inc., if SecondMarket's valuations are accurate.

That's what the TechCrunch blog reported Friday, basing its estimate on information provided by SecondMarket — an exchange for shares of private company stock — and from its sources.

Facebook shares passed $50 a share on the relatively limited number of shares that have actually changed hands using SecondMarket.

SecondMarket’s chief strategy officer Jeremy Smith told Beet.TV this week that about $100 million worth of Facebook stock has been traded through his exchange.

This makes estimates and comparisons to what the company might be worth on the public market highly speculative.

But real shares are being exchanged for real money in the belief that the valuations are legitimate.
