In a recent regulatory filing, Twitter Inc had increased the share price for its initial public offer by 25%. At this rate, it would be able to raise nearly USD1.75 billion as demand increases.

The microblogging site is now offering 70 million shares at a price range between USD23 and USD25 per share. The market valuation at the upper range would put Twitter at USD13.6 billion. In a previous filing, the price range was between USD17 and USD20 per share.

According to many quarters, Twitter has attracted sufficient interest to be able to sell all of its offered shares before bankers start booking orders for them. Twitter CEO Dick Costolo had been travelling all over the United States to justify its claim that as an unprofitable company, it would need to invest in itself to improve its advertising products as well as expand its user base and further improve its existing infrastructure.

At the top of its price offer range, the San Francisco based social media site would be valued at 11.8 times the company's projected sales for 2014, which has been pegged at USD1.15 billion. This valuation is 9.5 times worth its initial estimates. Comparatively, Facebook Inc was at 11.5 times while LinkedIn Corp was at 12.2 times.
