Twitter plans stock market flotationFriday 13 September 2013 09.44
Social networking site Twitter has submitted documents ahead of a planned flotation on the stock market.
The announcement was made on the site itself and explained that a form had been submitted to the US Securities and Exchange Commission (SEC) ahead of a planned initial public offering (IPO).
The tweet read: "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."
The firm followed up the tweet with a picture of the Twitter offices and a message reading: "Now, back to work."
Twitter was founded in 2006 and is based in San Francisco. There are 200 million users worldwide.
400m tweets are sent a day.
It is one of the largest and most powerful social media platforms in the world and disseminates a huge volume of information.
As it has grown, it has been used as a tool by celebrities, journalists and millions around the globe.
The announcement to float on the stock market has been long-expected.
It is expected to be valued at up to $10bn.
The company, which recently installed a "report" button following a number of complaints of abuse on the site, has been using adverts to boost income ahead of the announcement.
The move comes after Facebook floated on the US stock market in May 2012 for $104bn.
Despite seeing an initial slump in shares, it has since had a resurgence.
