SPACs have been around for decades and often existed as last resorts for small companies that would have otherwise had trouble raising money on the open market. But they’ve recently become more prevalent because of the extreme market volatility caused, in part, by the global pandemic.

While many companies chose to postpone their IPOs due to the pandemic, others chose the alternate route to an IPO by merging with a SPAC. A SPAC merger allows a company to go public and get a capital influx more quickly than it would have with a conventional IPO.
