Just how much will it cost to buy into Facebook?

(CNN) — We now know how much it will cost investors to buy into Facebook, 38-dollars a share.

The company hopes to raise 16-billion dollars with its initial public offering. If it does, that will be the largest tech I-P-O in history.

Facebook’s underwriters will start selling shares to their clients at that 38-dollar price tonight. Those clients, typically hedge and mutual funds or large institutional investors, can then sell them on the open market Friday morning.

Average investors will be able to buy shares Friday after the NASDAQ opens
