Internet phone firm Skype hopes to raise up to $US100 million in a stock market flotation.
The Luxembourg-based company plans to list in on the Nasdaq, the BBC reports.
Skype's software lets computer and mobile phone users talk to each other for free and make cut-price calls to mobiles and landlines.
The company, which has 560 million registered users, has not specified when its shares will go on sale, or at what price.
The online auction site, eBay, bought Skype for $US2.6 billion in 2005, but sold 70% of the company for $US2 billion last year.
Skype says it made a net profit of just over $US13 million in the first six months of the year.
