The long-awaited tech IPO of the year — perhaps of the decade — is on. Facebook will file its paperwork for an Initial Public Offering on Wednesday, according to a report from the Wall Street Journal.

If it comes to pass, this will be the largest tech IPO in history, yielding around $10 billion for the social network. The next-largest tech IPO is Infineon, a German company that raised $5.9 billion in 2000. Google’s 2005 IPO, as big a deal as it was, didn’t even reach the $2 billion mark.

Details are scarce, Facebook isn’t commenting, and the WSJ’s source is unnamed. But the Journal has a track record on such stories that is hard to dispute. The $10 billion share offering would yield the company a total valuation of $100 billion, the paper says, which is right in line with where we expected it to be.

Facebook halted its trading in secondary markets for three days earlier this week — the strongest signal yet that an IPO is coming soon.

The WSJ also reports that Wall Street giant Morgan Stanley will manage the offering, and that Goldman Sachs will be “intimately involved.” That’s a blow for Goldman, which managed a billion-dollar private share offering for Facebook this time last year.

Check back in later — we’ll add more details as we get them.

An initial public offering (IPO) or stock market launch, is the first sale of stock by a private company to the public. It can be used by either small or large companies to raise expansion capital and become publicly traded enterprises. Many companies that undertake an IPO also request the assistance of an investment banking firm acting in the capacity of an underwriter to help them correctly assess the value of their shares, that is, the share price.
