Cloud storage provider Dropbox has reportedly received over $500 million in debt financing led by J.P. Morgan. The infusion comes very soon after the company raised a behemoth $350 million Series C round at a $10.4 billion valuation in February of this year. It also comes shortly after Box, one of Dropbox's main competitors, filed for a $250 million IPO. Is Dropbox's next move to go public? It's reported that the company doesn't have specific plans for how it will use the new capital, but a 2014 IPO is highly likely.
