You may soon be able to buy a stake in Facebook.

The Wall Street Journal is reporting that the social networking giant is preparing an initial public offering (IPO) of stock, and could file regulatory papers as early as Wednesday.

The report said the move could earn Facebook as much as $10 billion US with the company valued between $75 billion to $100 billion.

Comparatively, Google raised $1.67 billion with its IPO in 2004.

Facebook spokesman Larry Wu has so far declined to comment on the IPO speculation.
