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. EST (1700 GMT) amid strong investor demand for shares, according to two sources with knowledge of the process.

The microblogging network still intends to price shares on Wednesday for trading on the New York Stock Exchange on Thursday, the sources said.

The sources declined to be named because the process is not public.
