It’ll be interesting to see what’s in store for the IPO market in 2019, considering the possible impact of the recent government shutdown. Major companies such as Uber, Lyft, Pinterest and Airbnb have all indicated plans to go public and the shutdown is unlikely to derail their plans. For smaller companies, however, the window of opportunity might be more narrow and some companies may choose alternative capital access routes.
