The original expected range of $23 to $25 per share. With 70 million shares to be issued, the company—which is not yet profitable— will raise $1.82 billion, valuing the company at $18.3 billion, fully diluted.



"The fact that they started with a range, they were able to raise it and they were able to price it above the range means that there was unprecedented demand, lots of demand for this IPO and we'll see how well they do tomorrow," said Carol Roth, a former investment banker and CNBC contributor, on Wednesday evening after Twitter's stock priced.



The social media company said in its statement that it has also granted underwriters a 30-day option to purchase up to 10.5 million additional shares of common stock.
