Who's Next in Line for an IPO?

With Dropbox, Spotify and Xiaomi, 2018 has already seen several prominent unicorns take the plunge and go public. And while Sonos never really made it into the Unicorn Club before last week’s IPO, the maker of wireless multiroom speakers is the latest example of a well-known private company deciding to become a publicly traded one, with all its pros and cons.

Looking at CB Insights' current ranking of the most valuable startups in the world, several names catch the eye that could soon follow suit. Uber, its Chinese rival Didi Chuxing, Airbnb and SpaceX have all been linked with IPO rumors in the past, but none has announced any definitive plans as of yet.
