Twitter Inc is set to close the books on its $1.75-billion initial public offering a day earlier than scheduled, on Tuesday at 12:00 p.m. ET (1700 GMT), amid strong demand for shares, two sources with knowledge of the process said. The microblogging network still intends to price shares on Wednesday, which will commence trading on the New York Stock Exchange on Thursday, said the sources, who declined to be named because the process is not public. Goldman Sachs Group Inc is leading Twitter’s initial public offering, alongside Morgan Stanley and JPMorgan Chase & Co. A spokesperson for Goldman declined to comment. A spokesperson for Twitter could not be reached immediately for comment.
