Goldman Sachs ( GS ) is the lead underwriter, sources told CNBC. Other underwriters are expected to be named when the S-1 filing is made public.

Shares of social media companies like Facebook ( FB ) and LinkedIn ( LNKD ) ticked slightly higher in after-hours trading after Twitter disclosed it had filed.

The company did not reveal any additional details, including any information on timing, other than to confirm the tweet is authentic.

Twitter has been valued at around $10 billion. The IPO is likely to be Silicon Valley's most anticipated debut since Facebook went public last year.
