SPAC, or special purpose acquisition company, is a shell company that raises money through an IPO with the sole purpose of acquiring a private company.
Often called blank check companies, SPACs offer an alternative path to public markets that has reshaped how companies go public.
After a dramatic boom and bust cycle, SPACs have entered a new era of disciplined investing with stronger regulations. Understanding how they work is essential for any investor evaluating opportunities in today's market.
What Is a SPAC and How Does It Work
A SPAC is formed by a group of sponsors, typically experienced investors or industry executives, who raise capital through an IPO. The funds raised are placed in a trust account, usually invested in U.S. Treasury securities, until the SPAC identifies a private company to acquire.
Investors purchase SPAC units during the IPO, typically priced at $10 per unit, which include common shares and warrants. The warrants give investors the right to buy additional shares at a set price in the future, adding potential upside beyond the share price itself.
If the SPAC fails to complete an acquisition within its deadline, usually 18 to 24 months, the trust is liquidated. Investors receive their pro-rata share of the trust funds back, making the $10 floor a built-in downside protection mechanism.
The SPAC Lifecycle: From IPO to Merger Target
Phase one, IPO and target search
After going public, the SPAC sponsor team searches for a suitable acquisition target that aligns with their stated investment thesis.
This phase requires identifying undervalued or high-growth private companies willing to merge rather than pursue a traditional IPO.
Phase two, de-SPAC transaction
Once a target is identified, shareholders vote on whether to approve the merger, known as the de-SPAC transaction. Shareholders who disagree with the proposed deal can redeem their shares at the trust value, typically around $10 per share.
Phase three, post-merger trading
After the merger closes, the combined entity trades as a regular public company on the stock exchange.
This is where the real test begins, as the company must now deliver on the growth projections that justified the deal.
SPACs vs Traditional IPOs: Key Differences
Speed and certainty
Traditional IPOs require months of SEC review, roadshows, and bookbuilding before a company can list on exchanges. SPACs can take a private company public in as little as three to five months, offering a faster and more predictable timeline.
Pricing dynamics
In a traditional IPO, the offering price is set through investor demand during bookbuilding, which can lead to underpricing or volatility.
SPAC mergers allow the target company to negotiate a fixed valuation directly with the sponsor, providing more pricing certainty.
Regulatory alignment
Since July 2024, the SEC has adopted rules that align SPAC disclosure and liability requirements with traditional IPOs. De-SPAC transactions are now treated as a "sale" under the Securities Act, removing the safe harbor for forward-looking projections.
Risks of Investing in SPACs
Sponsor conflicts of interest
SPAC sponsors typically receive 20% of the post-IPO equity, known as the "promote," creating an incentive to complete any deal rather than the best deal. This misalignment of interests is one of the most significant investment risks that SPAC investors face.
High redemption and dilution
When a large percentage of shareholders redeem before a merger, the remaining investors face significant dilution from sponsor shares and warrants. This dilution effect means the actual cost basis per share can be far higher than the initial $10 IPO price.
Post-merger performance
Historically, more than 90% of de-SPAC companies have traded below their $10 IPO price after completing mergers. Sectors like electric vehicles, space technology, and biotech saw particularly high failure rates during the 2021-2023 SPAC bubble.
Notable SPAC Deals and Lessons Learned
Success stories
SoFi went public via SPAC in 2021 and used the proceeds strategically to acquire a bank charter and diversify its portfolio. By 2024, SoFi achieved sustained GAAP profitability, proving that disciplined capital allocation can overcome SPAC structural challenges.
DraftKings also merged through a SPAC in 2020 and has since become the dominant player in U.S. online sports betting. These successes share a common thread of credible sponsors, real operating businesses, and clear paths to profitability.
Cautionary tales
Nikola, once valued at $27.6 billion through its SPAC merger, became the poster child for SPAC-driven hype. Allegations of fraud, production delays, and financial shortfalls culminated in its bankruptcy filing in February 2025.
The SPAC 4.0 era
The market has evolved significantly since the bubble, with 2025 seeing over 120 SPAC IPOs raising more than $22 billion in aggregate.
Today's SPACs feature experienced repeat sponsors, performance-based incentives, and higher revenue thresholds for target companies.
Conclusion
SPACs remain a viable path for private companies seeking public market access, but they require careful evaluation from investors. The combination of stronger SEC regulations, more disciplined sponsors, and lessons from past failures has created a healthier SPAC ecosystem.
For investors looking to build a diversified portfolio, understanding SPACs adds another tool for evaluating opportunities.
