Twitter announced Thursday, in a tweet, that it has submitted papers for a stock offering, the most hotly anticipated in the tech sector since Facebook's last year.
"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," the company tweeted.
Twitter has become one of the fastest-growing and most influential social media services, used widely by celebrities, journalists and others.
The company said earlier this year it had "well over 200 million" active users, although some analysts say the figure is much higher.
