As if $240 million from Microsoft wasn’t enough, it looks like Facebook might be courting another significant chunk of money. This is purely on rumor status for the time being, but word on the streets is that the company might be seeking as much as $500 million from two unnamed hedge fund sources. New York-based investment groups have reportedly already signed on for a combined $500 million investment, that would place a total of $740 million of equity at the hands of the social networking powerhouse. That would give them more than enough money to fund their increasing stable of employees, as well as continue along the road towards expansion and world domination. As with all rumors, we’ll wait until we’ve seen concrete confirmation to call it, but this sounds just crazy enough to be true.
