If today’s announcement that Facebook was acquiring Instagram wasn’t hot enough already, here’s a little fuel for the picture-sharing fire: Instagram had just closed a $50 million round, at a valuation of $500 million.

According to TechCrunch, Sequoia, Thrive, Greylock and Benchmark were all in on the round. Now here’s the mind-blowing part – The investors doubled their money in less than 2 business days, as the funds were apparently wired to Instagram on Thursday night.

The company had previously raised a seed, Series A and Venture round, totaling $47.5 million. Adding in the present $50 million round for a total of $97.5 million Instagram walks away with the lion’s share of over $900 million; a huge chunk of cash for anyone, but even bigger for Instagram and its 12 employees.

Regardless of whether Instagram is just the YouTube of photos or not, the move is still huge.
