Update: What is Facebook Worth After LinkedIn IPO?

Although Facebook competes with LinkedIn (NYSE:LNKD), there must’ve been cheers in the hearts of The Social Network’s employees today. If LinkedIn is able to make a market near $100 a share, LinkedIn is roughly worth $9.45 billion. So what does that make Facebook worth?

Probably ~$100 billion, or twice as much as what Goldman Sachs (NYSE:GS) claimed merely a few months ago. To arrive at that figure, we look at today’s closing market value of $8.91 billion for LinkedIn which equals 24 times projected 2011 revenue, then apply that multiple to Facebook’s projected 2011 revenue.

That means Mark Zuckerberg has already built a more valuable business than Ray Kroc’s McDonald’s (NYSE:MCD) which has a market cap of only $85.6 billion. It also means Facebook has already created a more valuable business than Anheuser-Busch InBev NV (NYSE:BUD) — a company that has been nurturing college kids much longer than social media.
