More companies went public via special purpose acquisition companies, or SPACs, during 2020 and 2021 than in all previous years combined. Also known as blank-check companies, SPACs brought many high-profile companies to the public markets, including Lucid Motors (NASDAQ: LCID) and DraftKings (NASDAQ: DKNG), as well as many early-stage businesses that likely wouldn't have gone public without the SPAC route. During this massive SPAC boom, no sponsor of blank-check companies has received more attention than Chamath Palihapitiya.
