The company made the announcement in a tweet, though details were as limited as the 140-character count beyond the initial announcement.
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
The IPO may still be a while in the making, but analysts have begun studying it to determine whether it will be a good investment or whether it will flop in the way Facebook did.
Twitter's value has jumped as more users utilize the 'sponsored tweets' section. With more than 200 million users, many believe the sky is the limit with Twitter, with an estimated value at $10 billion.
There is still a question of whether Twitter will be profitable when it is up for an IPO or if it will continue to become profitable as it tries to keep up with its hype. Both LinkedIn and Facebook have been gaining value in recent months, but buyers will have to determine for themselves whether Twitter is a trend or a long-term investment.
