SPAC
A SPAC (special purpose acquisition company) is a shell company that raises IPO capital to acquire a private company within 18 to 24 months. Also called a "blank-check company," the SPAC merges with its target so the target becomes publicly traded without going through a traditional IPO, or liquidates and returns capital to investors if no acquisition is completed. SPACs have existed for decades but exploded in 2020 to 2021 before collapsing sharply, and now occupy a smaller niche than at peak.
The mechanic, simplified: a SPAC sponsor (typically a well-known executive, investor, or operator) forms a shell company and IPOs it, raising capital from public investors who buy "units" (typically $10 each) consisting of one share and a fraction of a warrant. The capital sits in a trust earning low yield while the sponsor searches for a target. When a target is identified, shareholders vote on whether to approve the combination; those who vote no can redeem their shares for the trust value plus interest. Approved deals close and the combined company trades under the target's identity. The 2020 to 2021 boom: 248 SPAC IPOs in 2020 raised $83 billion, then 613 SPAC IPOs in 2021 raised $162 billion (SPAC Research / Refinitiv data), driven by retail enthusiasm, low interest rates, and sponsor incentive structures that paid sponsors regardless of post-deal performance. The 2022 to 2024 bust: SPAC IPOs collapsed to fewer than 90 in 2022 and below 30 in 2023; many completed SPAC mergers traded at large discounts to combination value; high-profile failures (Lordstown Motors, Lucid below combination price, WeWork) damaged investor confidence; SEC enforcement actions tightened sponsor incentive disclosure. The post-2024 SPAC market is much smaller, more selective, and focused on companies where the SPAC route offers genuine advantages (faster timeline, forward-looking projections allowed under PSLRA safe-harbor that traditional IPOs disallow, complex businesses that fit poorly with conventional IPO marketing).
Ryan's Take
SPACs were a useful financial instrument that got captured by a frenzy and produced a lot of bad deals. The structural problems were always obvious if you looked: sponsor incentives didn't align with public shareholders, projections were dramatically more aggressive than would have been allowed in a traditional IPO, and many of the targets were companies that traditional underwriters wouldn't have brought to market. The 2020 to 2021 boom let a generation of mediocre companies go public who shouldn't have, and most of them got punished accordingly. The instrument isn't dead, but it's specifically useful now for a narrow set of cases where the traditional IPO process doesn't fit, not as the default it briefly became.
What founders get wrong: Considering a SPAC because traditional IPO timelines feel slow, without modeling the post-combination shareholder dynamics. SPAC mergers often see significant redemptions before close (sometimes 80 to 95 percent of public shareholders redeem), which means the company gets dramatically less capital than the headline trust size suggests. Plan for redemption scenarios, not the headline number.

FAQ
What is a SPAC?
Special purpose acquisition company. A shell company that raises capital through a traditional IPO with the sole purpose of acquiring a private company within 18 to 24 months. The target then merges with the SPAC and becomes publicly traded, bypassing the traditional IPO process. Also called a blank-check company.
Why did SPACs boom and then crash?
The 2020 to 2021 boom was driven by retail enthusiasm, low interest rates, and sponsor incentive structures that paid sponsors regardless of post-deal performance. 613 SPAC IPOs raised $162B in 2021. The 2022 to 2024 bust came from poor post-merger performance, high-profile failures (Lordstown, WeWork), and tightening SEC enforcement on sponsor incentives.
Are SPACs still relevant?
Yes, but in a much smaller, more selective form. SPAC IPOs dropped below 30 in 2023 from 613 in 2021. The post-2024 market focuses on cases where the SPAC route offers genuine advantages: faster timeline, forward-looking projections allowed under PSLRA safe-harbor, or complex businesses that fit poorly with conventional IPO marketing.
