In its filing, Facebook, which has more than 845 million users worldwide, said it was seeking to raise $5 billion, according to a figure used to calculate the registration fee. The Wall Street firms underwriting the I.P.O. are Morgan Stanley, JPMorgan Chase, Goldman Sachs, Bank of America-Merrill Lynch, Barclays Capital and Allen & Company. When Facebook was valued at $23 billion, Forbes magazine estimated his wealth at $6.9 billion.

At that lofty valuation, Facebook would be much bigger than many longer-established American companies, including Abbott Laboratories, Caterpillar, Kraft Foods, Goldman Sachs and Ford Motor.
