Is Facebook's IPO Mark Zuckerberg's Birthday Gift To Himself?

Facebook's chief executive turns 28-years-old today and many expect the young hot shot is planning a huge b-day gift for himself.

The young entrepreneur, famous for his hoodies and jeans attire, is expected to make his company's IPO public on Friday (May. 18).

Sources believe Facebook's stock will hit the Nasdaq market for the first time at the end of the work week. The IPO could value Facebook at nearly $100 billion, which would make it larger than mega brands like Disney and Kraft.

Talk about a birthday present.
