WSJ:

The social networking firm is now targeting a time frame of April to June 2012 for an initial public offering, said people familiar with the matter. The company is exploring raising $10 billion in its IPO—what would be one of the largest offerings ever—in a deal that might assign Facebook a $100 billion valuation, a number greater than twice that of such stalwarts as Hewlett-Packard Co. and 3M Co.

That’s just an unbelievable amount of money.
