Betty Liu, Executive Vice Chairman for NYSE Group, explains:

Why have SPACs been so popular recently?

Well, that's because companies are embracing newer ways to tap the public markets outside of the traditional IPO. You've heard me talk about direct listings, for instance. And now SPACs are having a very big year, this year. In fact, nearly a third of all US IPO proceeds raised have been raised through SPACs in the first half of 2020.
