Twitter got off to a pretty big start as a public company, opening up at $45.10 (73.5% higher than its set price of $26). That price values Twitter just shy of $32 billion.

Also, Patrick Stewart helped ring the opening bell.

As of the time of this writing, TWTR is trading at $45.85.

So yeah, a pretty good start for a company not expected to be profitable until 2015.
