How many unicorns will exit before the market turns?

Hello and welcome back to our regular morning look at private companies, public markets and the grey space in between.

Today we're digging into unicorns: how many will find an exit through an acquisition (selling themselves to a larger company) or an IPO (starting to trade as a public company) before the market turns?

When the business cycle does eventually turn ill, it's generally expected that private capital will become scarcer, something that could harm yet-unprofitable unicorns. In turn, backers of private companies worth at least $1 billion could see the value of their investments decline or implode. The number of unicorns that manage to exit before a market turn is, therefore, something to keep an eye on.

This is doubly true as the number of un-exited unicorns continues to rise. Despite unicorn IPOs and acquisitions (more on that in a moment), the number of private companies worth $1 billion (unicorns that need an eventual exit to return capital to their backers who expect eventual, profitable liquidity) has risen each quarter for years now.

This has led to hundreds of unexited unicorns worth more than $1 trillion in total, according to the Crunchbase leaderboard. That's a lot of corporate value to shift before the business cycle heads negative, possibly closing the IPO window and bringing winter to the sort of private finance that unicorns have long depended on.

In Q3 of 2017, there were 250 unexited unicorns according to the leaderboard, 39 unicorns that had gone public and 24 more that had been acquired. A year later those numbers rose to 307 unexited unicorns, 79 unicorns that had gone public and 40 more that had been sold.

In its most recent update for Q3 2019, the same dataset indicates that there are 400 unexited unicorns, 112 that have gone public and 50 that have been sold.

Doing the math, in Q3 2017 80 percent of unicorns were still private and independent (unexited). In Q3 2018, that improved to 72 percent. And, at the end of Q3 2019, the percent improved modestly to a little over 71 percent.

We can see, then, that the portion of unicorns that have managed to find an exit has improved over the last few years. Less encouraging, however, is that the raw number of unicorns still in hunt of an exit has grown by leaps and bounds.

In chart form, it looks like this:
