Many start-ups with big names and even bigger valuations are planning to go public in 2019.

Lyft, Slack, Pinterest and Postmates have already filed. Uber and Airbnb are expected to join before the end of the year. But even with this anticipated consumer tech IPO bonanza, there is strong evidence that the traditional IPO is dying. These companies themselves have stayed private longer than they have in previous decades. And instead of chasing a listing on public markets, the next batch of superstar start-ups are likely to stay private longer.
