After months of speculation, Twitter has finally set its initial public offering in motion.
Twitter sent out a tweet on its own Twitter account saying that it had "confidentially submitted an S-1 to the SEC for a planned IPO."
A Twitter spokesperson confirmed the tweet but declined to elaborate.
We've confidentially submitted an S-1 to the SEC for a planned IPO. This Tweet does not constitute an offer of any securities for sale.— Twitter (@twitter) September 12, 2013
