Boom! From Twitter Alone, Jack Dorsey Is A Billionaire

When Twitter stated its $26 price per share yesterday, co-founder Jack Dorsey was expected to make a lot of money.

He'd have made north of $600 million at that price, but he wouldn't have been a billionaire.

Now, Twitter is trading at $45.

So Jack Dorsey and his 23,411,350 shares are now worth about $1.05 billion. If Square, his other company, goes public next year, his billionaire status will be solidified.

Congrats!
