Twitter on Thursday announced that it has filed documents with the Securities and Exchange Commission for an Initial Public Offering, or IPO. “We’ve confidentially submitted an S-1 to the SEC for a planned IPO,” Twitter said in a post on its popular social networking site. “This Tweet does not constitute an offer of any securities for sale.” Twitter is able to file its S-1 confidentially because its annual revenue is less than $1 billion, and the document will remain confidential until three weeks prior to the offering as a result.

According to Bloomberg, Goldman Sachs will be the lead underwriter on Twitter’s IPO.

At last count, Twitter had approximately 200 million monthly active users. Twitter will become the latest social networking giant to take its company public; Facebook last year went public with the biggest Internet IPO in history, raising $105 billion.
