In 2021, 613 blank-check companies went public and raised $162.5 billion - more money than every previous year of SPACs combined.1 None of them made anything. None of them sold anything. Each was an empty shell with a name, a banker, and a promise: trust us to find a private company worth merging into, and you can ride the deal as if you'd gotten in early. For a few months, the most fashionable thing in finance was a company that didn't exist yet. Then the floor fell out.
The official story is that the SPAC was a clever democratization of the IPO that overheated and crashed - a good idea ruined by a frenzy. That story is wrong. The crash wasn't the structure failing. It was the structure working exactly as designed, and the design had a built-in answer to the only question that matters: when the music stops, who is left holding the loss?
The sponsor gets paid for the merger, not the outcome
Start with the person who builds the shell. A SPAC sponsor puts up a small amount of seed capital and, in return, typically receives founder shares worth a large slice of the eventual combined company - the 'promote' - for almost nothing. Here is the load-bearing detail everyone glossed over in 2021: that promote pays out when a merger closes, not when it succeeds. The sponsor's incentive is to do a deal, any deal, before the clock runs out and the trust has to be returned. A great target and a terrible target both trigger the same payday. The structure rewards motion, not judgment - and motion is exactly what a market awash in cheap capital produced.
That promote doesn't materialize out of thin air. It dilutes the shares of everyone else in the deal. So does the warrant overhang. The economics have to land on someone, and the genius - if that's the word - of the SPAC is that it offered a clean way for the sophisticated to step out of the way before the bill arrived.
The redemption right protected the people who least needed protecting
The selling point pitched to retail was a guarantee: every SPAC holds investor cash in trust at around $10 a share, and you can redeem at that floor plus interest if you don't like the merger. Downside protected. What the pitch left out is that this right is a trap door, and the people who knew where it was used it. Institutional arbitrageurs bought in, collected the near-riskless $10 floor at redemption, and - crucially - kept their warrants for free.9 They took the protection and left. The merger risk they walked away from didn't vanish. It got concentrated onto the shareholders who held, which is to say the retail investors the whole instrument was marketed to as a democratizing on-ramp.
Read that number carefully, because it is the whole thesis in one figure. Northwestern's Kellogg researchers found non-redeeming holders lost an average of about a quarter of their stake the moment the dilution they'd inherited got priced in.7 The $10 floor was real - it just belonged to whoever was clever enough to step out at $10. Everyone else was buying the right to absorb the promote.
| Sponsor | Redeeming arbitrageur | Retail holder | |
|---|---|---|---|
| Gets paid when | The merger closes | Before the merger, at $10 + interest | Only if the company performs |
| Bears dilution | No — creates it | No — redeems out | Yes — inherits it |
| Keeps warrants | Yes | Yes (for free) | Yes, but on a falling stock |
| Typical outcome | Guaranteed promote | Near-riskless return | ~25% devaluation[[cite:s7]] |
Why the missing quiet period let a truck company sell a video
There's a second structural quirk that turned a flawed instrument into a fraud machine. A traditional IPO comes with a 'quiet period' - rules that restrain what a company can hype while it's going public. A SPAC merger has no equivalent. That gap is not a footnote; it's the difference between a careful prospectus and a CEO posting promotional claims to social media while the deal is live.
Nikola is the case study prosecutors reached for. The electric-truck startup went public by merging with the SPAC VectoIQ in June 2020 and rocketed to a peak market cap of nearly $30 billion - and its founder, Trevor Milton, exploited precisely the absence of a SPAC quiet period to make fraudulent statements online.5 The company later settled SEC fraud charges for $125 million; Milton was convicted of securities and wire fraud and sentenced to four years and $168 million in restitution.4 The fair distinction is that the SPAC didn't commit the fraud - a person did. But the vehicle handed him the open microphone that a traditional IPO would have switched off. The structure was the enabler, not the actor.
“Milton exploited features of the SPAC structure different from a traditional IPO.”5
The cliff, in two numbers
Watch how fast it unwound. SPAC IPOs peaked in the first quarter of 2021 with nearly $100 billion raised across roughly 300 deals. By the first half of 2022, the same machine raised just over $12 billion, and the full-year SPAC IPO count collapsed to 86.6 That is not a market cooling. That is a market discovering, all at once, that the thing it was buying was structured to pass losses downstream - and refusing to be downstream anymore.
Didn't the SEC fix it - and didn't the rules just kill the market?
Two honest objections deserve answers. The first: the SEC stepped in. In January 2024 it adopted final rules, by a 3-2 vote, forcing disclosure of sponsor compensation, conflicts of interest, and dilution, and stripping away the legal safe harbor that had let de-SPACs publish rosy projections with little liability; the rules took effect that July.23 Good rules. But look at the dates. The disclosures that would have warned a retail buyer about the promote and the dilution arrived in 2024 - three years after the 2021 cohort had already bought in and been diluted. The fix protected a future investor. It could not refund the one the structure was built to find.
The second objection cuts the other way: dissenting commissioners warned the rules would extinguish SPACs entirely, and the doom didn't come. By 2025, 138 SPACs raised $25.8 billion - nearly triple 2024's $8.7 billion - and into early 2026 SPACs were again outpacing traditional IPOs by deal count.8 So the structure survived its own regulation. That's the most damning part, not the most reassuring: an instrument can keep raising billions while still being engineered to route risk toward whoever understands it least. Surviving and being sound are not the same claim.
Any time someone offers you 'access' to an opportunity, trace the incentive of the person packaging it. The dangerous structures are the ones where the promoter's payday is triggered by the transaction itself - the merger closing, the loan originating, the policy being sold - rather than by the outcome you actually care about. When the architect gets paid regardless of whether you win, you are not the customer of the deal. You are the inventory. And the cleaner the 'downside protection' sounds, the more carefully you should ask who is positioned to use it first - because a floor that the sophisticated can step onto before you usually means the dilution is waiting for whoever stays in the room.
The SPAC was sold as a democratized IPO - a way for ordinary investors to get in early on the next big thing. It delivered something close to the opposite: a structure where the sponsor was paid for motion, the smart money was paid for leaving, and the people invited in to feel like insiders were the ones holding the dilution when the merger priced. The boom wasn't an accident the market made and then corrected. It was a machine for moving risk to the people who couldn't see it - and it worked beautifully, right up until everyone could.
Disruption Vulnerability Assessment
An assessment that rates a company across the dimensions that predict disruption: how cheaply a challenger can serve the unsexy bottom of the market, how trapped you are by margins and a satisfied core. Blank to score your own position before the cliff; filled as the worked example showing where the story's incumbent was already exposed while the numbers still looked great.

- 6SPAC IPOs peaked in Q1 2021 with nearly $100 billion raised from approximately 300 IPOs; by contrast, SPAC IPOs over the first two quarters of 2022 raised just over $12 billion, and the number of SPAC IPOs in 2022 fell to 86.
- 7Non-redeeming SPAC shareholders experience an average post-merger devaluation of approximately 25.2% (from the $10 SPAC share price to an average of $7.48), because sponsor founder shares and warrant dilution are offloaded onto those who do not exercise the redemption right.
- 8After the 2020–2021 boom produced over $220 billion in capital raised and the subsequent collapse left the average de-SPAC down 40% by late 2022, a 2025 recovery saw 138 SPACs raise $25.8 billion — nearly 3x the $8.7 billion raised in 2024 — and in the first two months of 2026, 50 SPACs raising $10 billion outpaced 24 traditional IPOs raising $7 billion.
- 9SPAC IPO investors who redeem their shares collect the $10 floor plus accrued interest and keep their warrants for free, generating a near-riskless annualized return while offloading merger dilution onto non-redeeming shareholders.
- 10Federal prosecutors stated in the indictment that Milton was able to make fraudulent public statements because Nikola went public via a SPAC rather than an IPO, and Milton was therefore not subject to quiet period restrictions.
