Twitter announced Thursday that it has privately filed for its first public sale of shares.
In a message sent on the corporate account of its own service, Twitter said Thursday afternoon,
“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.”
Twitter was founded in 2006 by Jack Dorsey and Biz Stone, and has grown to more than 200 million users who share their thoughts in bursts of no more than 140 characters at least once a month, with estimates of total users surpassing 500 million.
