The Japanese subsidiary of Internet search portal Naver, which operates the Line mobile messaging service, plans to list the service on the U.S. stock market as well as the Nikkei, Bloomberg reported Friday.
It is unclear whether Line will be listed on the New York Stock Exchange or Nasdaq.
Naver said in a notice to the Korea Exchange that the timing and the specific exchange has yet to be decided.
Line has some 480 million registered users around the world and is particularly popular in Japan with over 50 million users.
Analysts forecast that it would be valued at between W10 trillion to W20 trillion if it goes public in the U.S. and Japan (US$1=W1,030).
