Dropbox's latest filing with the U.S. Securities and Exchange Commission has the blogosphere in a tizzy this afternoon.
That's because the Form D filed on Monday revealed that the San Francisco-headquartered company raised another $325 million or so -- a sum that is only going to fuel more rumors about an initial public offering at some point this year.
Fortune reported that the cloud storage business actually raised closer to $350 million. Dropbox has not commented publicly on the matter.
According to the filing, the ceiling for the fundraising round is actually $450 million, meaning Dropbox might shoot even higher.
Allen & Company and Goldman Sachs were listed as brokers for the deal.
This week's SEC filing followsabout fundraising closer to $250 million, supporting speculation that Dropbox's valuation hovers around $10 billion.
Dropbox raised approximately the same amount during a Series B round back in 2011.
