"We’ve confidentially submitted an S-1 to the SEC for a planned IPO. This Tweet does not constitute an offer of any securities for sale."
And with that tweet, Twitter announced that is going public and will offer stock to the general public.
But not just yet.
That doesn't mean, however, that you can't get your hands on some shares before the stock offering. It's just a bit more complicated.
Like Facebook before it, there is a vibrant market for shares of Twitter on what's known as the "secondary market." WNYC's Ilya Marritz reported about this pre-Facebook's IPO. It's worth a listen. So is the story about how Twitter co-founder Jack Dorsey almost called the company "Twitch" (luckily, he didn't).
While the confidential nature of Twitter's filing with federal regulators doesn't give us a clear picture of the share price, if you can get your hands on some shares (which is getting tougher) the New York Times quotes Michael Pachter, an analyst at WedBush Securities who says, “Over the last couple of months, shares in the secondary market have risen to between $20 and $30. That’s what the private market values it right now, not that investors have any information, but that’s what they are willing to pay.”
