What is a SPAC in simple terms?

A SPAC, or special purpose acquisition company, is a shell company with no operations that raises money in an IPO for one purpose: to merge with a private company and take it public. It's also called a blank-check company because investors usually don't know which business it will acquire when they buy in.

How is a SPAC different from an IPO?

In a traditional IPO, a private company itself files to go public and sells shares directly to investors. With a SPAC, an empty shell company goes public first, then merges with a private business (a "de-SPAC" transaction) to bring it to market. A SPAC can be faster and gives the target more certainty over its valuation, though the SEC's 2024 rules narrowed some of those differences.

What happens if a SPAC doesn't find a company?

If a SPAC fails to complete a merger within its deadline (typically about two years) it's liquidated and the money held in trust is returned to investors, usually close to the $10 per share they paid.

Can I get my money back from a SPAC?

In most cases, yes. SPAC shareholders typically have redemption rights, meaning you can hand back your shares for your pro-rata share of the trust (around $10 plus any interest) before a merger is completed, whether or not you support the deal. This is a key feature that limits your downside while the SPAC searches for a target.

What is a de-SPAC transaction?

A de-SPAC is the merger between a SPAC and its target company that takes the target public. Once it completes, the combined business usually adopts the target's name and a new ticker symbol, and the shell company effectively becomes the operating company.

Why did SPACs become so popular and then crash?

SPAC issuance surged in 2020 and 2021, peaking at 613 IPOs in 2021, about 63% of all US IPOs that year. This boom was fueled by low interest rates, celebrity backers and retail enthusiasm. The boom proved unsustainable: many deals were low quality, post-merger performance was poor, interest rates rose and regulatory scrutiny increased, causing issuance to collapse in 2022 and 2023 before a more disciplined revival began in 2024.

What is a SPAC? Risks and how to invest

Finder makes money from featured partners, but editorial opinions are our own. Advertiser disclosure

A SPAC (special purpose acquisition company) is a shell company that raises money in an IPO for the sole purpose of merging with a private company and taking it public.
SPAC shares are typically priced at $10, and your money sits in a trust until the SPAC finds a target — usually within about two years, or it liquidates and returns your cash.
SPACs boomed in 2021, then collapsed. Most companies that went public this way now trade below their $10 starting price, though a more disciplined revival began in 2024-2025.
Before a merger, you can usually redeem your shares for your share of the trust (around $10), which limits your downside while you wait.

A special purpose acquisition company (SPAC) is a publicly traded shell company created for one reason: to raise money and merge with a private business, taking it public without a traditional IPO. SPACs have existed since the 1980s, but they exploded in popularity in 2020 and 2021 before crashing just as dramatically, so understanding both the mechanics and the risks matters before you buy in.

What is a special purpose acquisition company (SPAC)?

A SPAC is a company that goes public with no commercial operations of its own. Its only purpose is to acquire or merge with an existing private company and bring it to market. Because investors who buy in usually don’t yet know which company the SPAC will target, SPACs are also called shell or blank-check companies.

Most SPAC shares are priced at $10 at IPO, on the general assumption that the price will rise once a target is acquired and starts trading. Whether that actually happens is another matter entirely and one we’ll cover below.

The SPAC boom, bust and revival

SPAC activity is highly cyclical, and the numbers tell the story. Issuance peaked in 2021, collapsed through 2022 and 2023, and has staged a more measured comeback since 2024.

Period	US SPAC IPOs (approx.)	Context
2021 (peak)	613	Around 63% of all US IPOs that year
2023 (trough)	31	Issuance nearly dried up
2024	57	Early signs of a revival
2025	138	Roughly 40% of US IPO deal count

The 2024-2025 rebound is widely described as a more disciplined era: experienced sponsors, stronger institutional backing and tighter regulation, but far smaller volumes than the 2021 frenzy.

How do SPACs work?

SPACs follow a distinct path to market. Here’s the process step by step.

1. The SPAC is formed

A group of investors, known as the sponsors, begins the process of forming the SPAC. Like any company going public, the SPAC must complete an IPO registration with the US Securities and Exchange Commission (SEC) before it can list on a US exchange.

2. The SPAC goes to market

After its IPO, the SPAC trades publicly under its own ticker symbol and the public can buy shares. The proceeds raised are placed in a trust or escrow account, where they stay until a deal closes.

3. The SPAC seeks a target company

The sponsors search for a private company to merge with. A target must typically be found within about two years, or the SPAC is liquidated and the money in trust is returned to investors. Notably, that search has been taking longer lately and by 2024-2025, most SPACs needed more than two years to complete a merger.

4. The SPAC merges with its target

Once a target is named and the merger (known as a “de-SPAC” transaction) completes, the combined company usually takes on the target’s name and a new ticker symbol. At that point you can hold your shares or sell them.

SPACs vs. traditional IPOs

SPACs and IPOs are often mentioned together, but they’re not the same. In a traditional IPO, a private company files extensive paperwork with the SEC, courts institutional investors and negotiates pricing, which is a slow, uncertain process. A SPAC flips the sequence: the shell company goes public first, then merges with a private business, which can be faster and offers the target more certainty over its valuation.

The gap between the two has narrowed, though. In January 2024, the SEC adopted rules designed to bring de-SPAC transactions closer to the investor protections of a traditional IPO.

Why do companies use SPACs?

Private companies often choose a SPAC because it can be quicker and more predictable than a traditional IPO. The target negotiates its valuation directly with the sponsor rather than leaving pricing to volatile IPO demand, and smaller or earlier-stage companies can reach public markets with less friction. The trade-off is dilution from sponsor shares and warrants, plus, since 2024, tighter disclosure obligations that have reduced some of the speed advantage.

How to invest in SPACs

You can buy SPAC shares through a standard brokerage account, but the process differs from buying an established stock:

Research the sponsors. When you invest in a SPAC, you’re largely betting on the sponsors’ judgment. Look into their track record: have they run SPACs before, and were those deals successful?
Open a brokerage account. You’ll need one to invest. Compare brokerage account options by features and fees to find the right fit.
Search for the ticker. Use your platform’s search or stock screener to find the SPAC by ticker or company name.
Submit your order. Enter how many shares you want and choose a market or limit order.
Wait. After investing, you’ll wait for the SPAC to announce a target, which can take two years or more.
Hold, redeem or sell. Before the merger you can usually redeem your shares for your share of the trust (around $10). After the merger, you can hold or sell like any other stock.

How do I find SPACs to invest in?

SPACs aren’t advertised the way traditional IPOs are, so staying informed is key. You can follow investment news, track SPAC-focused research sites, or look on exchange listings for ticker symbols ending in “U”, which is a common identifier for SPAC units.

Are SPACs safe to invest in?

SPACs carry real risks, and recent history makes that clear. In the 1980s they earned a poor reputation for illiquid penny stocks and pump-and-dump schemes. Regulation has improved since, but the 2021 boom exposed a new set of problems: on average, companies that went public via SPAC lost roughly two-thirds of their value afterward, and more than 90% of de-SPAC companies now trade below the $10 reference price.

The core risks to weigh:

It’s a blind bet. When you buy in early, you often don’t know which company the SPAC will acquire and you’re trusting the sponsors.
Your money can be tied up. It can take two years or more for a SPAC to close a deal, during which your funds sit in trust.
Post-merger performance is often poor. The combined company may underperform badly once it hits the market, as the 2021-2023 wave showed.
Dilution. Sponsor shares and warrants can dilute the value of your holding after the merger.

On the protection side, in January 2024 the SEC adopted rules (new Subpart 1600 of Regulation S-K) requiring fuller disclosure of sponsor compensation, conflicts of interest and dilution, and making the target company a co-registrant, which means it shares legal responsibility for the deal’s disclosures. The stated aim is to give de-SPAC investors protections closer to those in a traditional IPO. And because you can typically redeem your shares for your share of the trust before a merger, your downside while you wait is limited.

What happens after a SPAC merges with another company?

After a de-SPAC merger, the new company usually takes the operating company’s name and a new ticker. From there, you can hold or sell your shares like any other security but outcomes vary enormously, as two well-known examples show.

DraftKings went public in April 2020 by merging with Diamond Eagle Acquisition Corp. It’s become one of the rare SPAC success stories, growing into a multibillion-dollar company that has traded well above its $10 debut price.

Virgin Galactic shows the other side. The spaceflight company went public via a SPAC merger with Social Capital Hedosophia in 2019 and its shares topped $50 during the 2021 mania. They then fell sharply, and in June 2024 the company carried out a 1-for-20 reverse stock split just to keep its share price high enough to stay listed on the NYSE. Several other space SPACs did the same.

The lesson: there’s no reliable way to predict how a de-SPAC stock will perform. Before investing, check whether the SPAC has flagged a target industry or sector, which can at least hint at what you may end up holding.

Bottom line

SPACs give retail investors a way to buy into a company as it goes public, and redemption rights limit your downside while you wait. But your money can be locked up for years, most de-SPAC companies have historically traded below their $10 starting price, and there’s no guarantee the merged company will succeed. The 2024-2025 revival is more disciplined than the 2021 boom, but the risks remain real. Compare brokerage account options to find a platform that fits how you want to invest.
