For the sake of comparison, the biggest business built on Facebook's platform, Zynga, was last reported to be valued at $5.51 billion. Two other new social network companies, Twitter and Groupon, were both recently looking for new funding at a mere $3 billion valuation each.
Given that Facebook has yet to go public, it's not fair to compare its valuation to the market caps for the biggest and most successful publicly traded technology companies. Still, we'll show you the numbers anyway: Yahoo ($21 billion), eBay ($39 billion), Amazon ($81 billion), Google ($186 billion), Microsoft ($217 billion) and Apple ($291 billion).
The $50 billion milestone, although unofficial because Facebook is private, still shows that many investors seem to have faith in the company's ambitions. Here's the letter reportedly sent out to SecondMarket auction participants:
To All Facebook Market Participants:
Thank you for your feedback and participation in last weeks Facebook auction. As we had hoped, there was robust seller and buyer participation the auction fully cleared at a per share price of $20.76. In addition, there was overwhelmingly positive feedback on the auction process. As a result, we will be continuing to conduct these auctions for the foreseeable future. For this week, the process will remain reasonably similar, with slight tweaks to the timeline. The reserve price for this week will be $20.60, the same as last week.
