Micro blogging site, Twitter has priced its issue at the upper range and is aiming to raise as much as $1.8 billion indicating that the investors have created demand for the shares.

The company has priced its shares at $26 per unit and will sell a total of 70 million shares. The price is above the target range of $23 to $25. The IPO is already oversubscribed several times at the rate of $25 a share, which is the higher end of the issue range. Underwriters for Twitter's IPO will stop taking orders at noon tomorrow in New York before a final price is determined by the company.

Twitter has reportedly chosen TWTR as its ticker symbol for the shares. The social blogging network with more than 200 million members worldwide had earlier said that it has filed S-1 to the Securities and Exchanges Commission for its planned initial public offering. Twitter is expected to be valued at up to $20 billion after its shares starts trading.

According to analysts, the stock might be priced in the range of $29 to $54 in the coming two months after the stock makes its debut on Thursday.
