Introduction
In 2020 and 2021, a strange new acronym started showing up everywhere in financial news: SPAC. Companies like DraftKings, Lucid Motors, and Virgin Galactic all went public not through the traditional IPO process, but through something called a Special Purpose Acquisition Company. Retail investors piled in, hoping to catch the next big thing before Wall Street did. Some made money, but many didn’t. Studies of the 2020–2021 SPAC wave later found that a large share of these companies were trading below their $10 starting price within a year of merging.
If you’ve ever wondered what a SPAC actually is, how it works, and whether it’s worth your money, this guide breaks it down in plain language, no finance degree required.
What Is a SPAC?
A SPAC, or Special Purpose Acquisition Company, is a publicly traded shell company created with one purpose: to raise money from investors and then use that money to buy or merge with a private company, effectively taking it public.
Think of it as a company with no actual business operations. It doesn’t sell products, employ a sales team, or generate revenue. Its only job is to find a private company worth acquiring and complete that deal within a set time frame, usually two years. That’s why SPACs are often nicknamed “blank check companies”, investors are essentially writing a blank check to the SPAC’s management team, trusting them to find a good deal.
Key SPAC Terms You Should Know
Before going further, here are the terms you’ll run into constantly when reading about SPACs:
Sponsor: The individual or group that creates the SPAC, raises the initial capital, and leads the search for a company to acquire. Sponsors are often experienced executives, investors, or even celebrities lending their name and credibility to attract investors.
Trust Account: The money raised from the SPAC’s IPO doesn’t sit in the sponsor’s pocket. It’s placed in an interest-bearing trust account, untouched until a merger is approved or the SPAC fails to find a deal and has to return the money to shareholders.
Warrants: Many SPAC shares come bundled with warrants, which give investors the right to buy additional shares at a fixed price in the future. Warrants can boost returns if the deal goes well, but they also dilute existing shareholders.
Redemption Rights: If shareholders don’t like the company the SPAC wants to merge with, they can usually redeem their shares for a portion of the trust account instead of becoming part of the new company.
De-SPAC: This is the industry term for the actual merger event, when the SPAC combines with the private target company and that company becomes publicly traded under a new ticker symbol.
How Does a Special Purpose Acquisition Company (SPAC) Work?
At its core, a SPAC is a two-step bet. First, you’re betting on the sponsor’s ability to find a good company to acquire. Second, once a target is announced, you’re betting on whether that company is actually worth investing in.
The sponsor typically puts in a small amount of their own capital and then raises the bulk of the funds through an IPO, selling shares to public investors, usually priced around $10 each. That money goes into the trust account while the sponsor searches for a target. Once a target is found and shareholders approve the deal, the private company merges with the SPAC and starts trading under its own name and ticker, skipping the traditional IPO roadshow process entirely.
The SPAC Process: From IPO to Merger
Formation and IPO
A sponsor forms the SPAC, files paperwork with the Securities and Exchange Commission, and takes the shell company public through an IPO, much like any other stock. Shares are usually sold in units priced at $10, often including a warrant.
Funds Held in Trust
Once the IPO closes, typically 100% of the money raised is placed into a trust account managed independently of the sponsor. This is meant to protect investors: even if the SPAC never finds a deal, shareholders are entitled to get their money back, plus accrued interest.
Searching for a Target Company
This is where the sponsor’s expertise matters most. They typically have 18 to 24 months to identify and negotiate a deal with a private company looking to go public. This is also the phase where speculation runs highest, and SPAC shares can swing based on rumors about which company might be the target.
The Merger (“De-SPAC”)
Once a target is identified, shareholders vote on whether to approve the merger. If approved, the private company merges into the SPAC’s public shell, and the combined entity begins trading under a new ticker symbol. Shareholders who don’t approve of the deal can redeem their shares for cash instead of holding onto the new stock.
A well-known example: in 2020, DraftKings merged with a SPAC called Diamond Eagle Acquisition Corp, allowing the sports betting company to go public faster than a traditional IPO would have allowed. By contrast, electric-truck maker Nikola’s 2020 SPAC merger with VectoIQ became a cautionary tale after the company’s founder was later convicted of fraud related to misleading investors about its technology. Not every deal is so dramatic in either direction, many are ordinary mid-market companies. For instance, in 2021 Sandbridge Acquisition Corporation merged with babytech company Owlet Baby Care in a deal valued at over $1 billion, taking Owlet public on the NYSE.
Why Do Companies Choose to Go Public via SPAC?
For private companies, merging with a SPAC offers a few real advantages over a traditional IPO. The process tends to be faster, often taking a few months compared to the year or more a traditional IPO roadshow can require. It also gives the company more control over valuation, since the price is negotiated directly with the SPAC rather than set through investor bidding during a roadshow.
SPACs are particularly attractive to early-stage or capital-intensive companies, like electric vehicle makers or space companies, that may not yet have the consistent revenue history traditional IPO investors expect. Lucid Motors and Virgin Galactic both used this route to access public markets and raise growth capital while their businesses were still pre-revenue or early-revenue.
SPAC vs. Traditional IPO: What’s the Difference?
A traditional IPO involves a company hiring investment banks to underwrite the offering, conducting a roadshow to pitch the business to institutional investors, and setting a share price based on that demand. It’s a rigorous, often lengthy process with significant regulatory scrutiny on the actual operating business before it goes public.
A SPAC merger flips that order. The “company” going public initially, the SPAC itself, has no operations to scrutinize. Regulatory review happens, but much of the detailed business analysis occurs after the deal is structured, during the merger announcement and shareholder vote, rather than before. This means retail investors often have less information available when they first buy into a SPAC compared to a company nearing a traditional IPO.
Pros of Investing in SPACs
Access to early-stage growth: SPACs let retail investors buy into companies at a stage usually reserved for venture capital or private equity firms.
Downside protection while waiting: Until a merger is announced and you choose to stay in, your money sits in the trust account, often earning interest, and you usually retain the right to redeem your shares for close to your original investment.
Speed to market: Because the process is faster than a traditional IPO, investors can gain exposure to a company sooner.
Cons and Risks of Investing in SPACs
Dilution: Sponsor compensation, warrants, and additional share issuances can significantly dilute the value of shares once a merger closes.
Poor post-merger performance: Many SPAC mergers have underperformed the broader market after the deal closes. Several high-profile 2020 and 2021 SPAC mergers, including some EV and clean energy companies, saw their stock prices fall sharply within a year of going public as growth projections failed to materialize.
Limited due diligence time: Shareholders often have only weeks to evaluate a proposed merger target before voting, far less scrutiny than a traditional IPO process typically allows.
Sponsor incentive misalignment: Sponsors are often financially motivated to complete a deal, any deal, before their time runs out, which doesn’t always align with finding the best possible target for shareholders.
How to Evaluate a SPAC Before Investing
Before putting money into a SPAC, whether pre- or post-merger, consider these questions:
Who is the sponsor, and what is their track record with previous deals or businesses? A sponsor with a strong operating history in the target industry is generally a better sign than a celebrity name attached for marketing purposes.
What is the merger target’s actual financial health? Once a deal is announced, look at revenue, profitability timeline, and competitive position, just as you would for any other stock, rather than relying on the company’s own growth projections.
How much dilution will shareholders face from warrants and sponsor shares? Read the merger proxy statement for details on share structure.
What’s the redemption rate among existing shareholders? High redemption rates can signal that informed investors don’t believe in the deal.
Conclusion: Key Takeaways
SPACs offer retail investors a faster, sometimes more accessible path to investing in private companies before they hit the broader public markets. But that access comes with real trade-offs: less due diligence time, sponsor incentives that don’t always match shareholder interests, and a track record of mixed post-merger performance.
If you’re considering a SPAC investment, the safest approach is to treat the pre-merger period as a waiting game backed by the trust account, and to apply the same rigorous research to the post-merger company that you would to any other stock before deciding whether to stay invested.
Frequently Asked Questions
Is a SPAC the same as an IPO? Not quite. A SPAC is a shell company that goes public first and then merges with a real operating business. A traditional IPO is when an operating company lists its own shares directly. The end result is similar, a company becomes publicly traded, but the path and the level of upfront scrutiny differ.
What happens to my money if a SPAC never finds a company to buy? If the SPAC fails to complete a merger within its deadline (usually about two years), it liquidates and returns the money held in trust to shareholders, typically close to the original $10 per share plus interest.
Are SPACs a safe investment? No investment is “safe.” SPACs offer some downside protection before a merger because of the trust account, but after a merger closes they carry the same risks as any stock, and historically, many post-merger SPAC companies have underperformed.
