Rumor has it that there was an all hands meeting at Facebook yesterday. To discuss what? Nobody has the details but early the morning the New York Post says that the announcement of an investment in Facebook by Google or Microsoft is likely to be announced in the next 24 to 48 hours. According to the article, Microsoft is prepared to pay any price to keep Google out of the magical land of Facebook.

This apparently could result in a $15 billion valuation of the extremely hyped social network. As Peter Lauria states in the article, this would result in a $1.5 billion investment for a 10 percent stake or $750 million for a 5 percent stake. Not a bad of financing for Facebook! Given that the current employees all have stock options and the executive team surely doesn’t want to piss anybody off, my guess is that employees were given notice of the impending news and also given the option to sell some shares at the current valuation.

That would be a fun meeting to be sitting in on. While all I can do is speculate about what took place in the meetings yesterday, the amount of chatter going around in the industry means something is surely about to happen in the coming days. What it is, I can’t tell you but according to the New York Post, it is going to be a serious investment by Microsoft or Google.
