Twitter revealed yesterday that it officially filed paperwork to go public. According to the most recent estimates, the company is valued at around $11 billion, and is able to file the IPO confidentially thanks to the Jumpstart Our Business Startups act, which allows companies to do precisely what Twitter is doing at the moment. The documents filed at the moment, though, mean that the company isn’t going public immediately, only that it has signaled its intent to do so in the next few weeks. It seems like a shrewd move by the company to get ahead of any potential rumors of the offering happening in the first place, and it’ll be important to keep a close eye on this story as it develops.
