Japan's Line has priced its IPO at the top of its marketed range, putting the messaging app firm on course to raise up to $1.3 billion and reflecting demand from investors keen on a rare opportunity to invest in a high-profile tech startup.

Line's initial public offering (IPO), the world's biggest for a technology firm this year, offers access to a growth area of tech invariably monopolized by private equity. It also comes as political and economic uncertainty following Britain's vote to exit the European Union pushes money toward relative stability in Asia.
