SPAC Mania: When Blank Checks Went Mainstream
In 2021 more than 600 empty shell companies raised over 160 billion dollars to buy businesses nobody had picked yet. Part of our Looking Back series on 2020 to 2026, written from 2026.
The Blank Check Machine
A SPAC, a special purpose acquisition company, is a shell with no business at all. A sponsor raises money in an IPO, typically at 10 dollars a share, parks it in a trust, and promises to find a private company to merge with within about two years. The merger, called a de-SPAC, makes the target instantly public without the traditional IPO gauntlet. SPACs existed for decades as a backwater. Then in 2020 they raised 83 billion dollars across 248 deals, more than the previous decade combined, and in 2021 they went vertical, 613 SPAC IPOs raising about 162 billion dollars. At the peak, celebrities from athletes to musicians had their own blank check vehicles, and this entry is about why that happened and why it ended the way it did.
Why Everyone Loved the Structure
Every party had a reason. Private companies got a faster route to public markets and, unlike in a traditional IPO, could legally market themselves with multi year financial projections, a gift for pre revenue businesses with great stories. Sponsors got the promote, typically 20 percent of the SPAC\'s shares essentially for free once a deal closed. Retail investors got access to venture style companies they were never allowed to touch. And hedge funds got a nearly risk free trade, buy at 10, collect interest in trust, and use the built in redemption right, the option to take your 10 dollars back instead of funding any merger you dislike, while keeping free warrants as a bonus.
Read that list again and notice what is missing. Nobody in the chain was paid for the merged company performing well after the deal. That absence is the entire story.
The sponsor earned their 20 percent promote for closing a deal, any deal, before the clock ran out. When someone is paid for activity rather than outcomes, you will get activity. Outcomes are optional.
The Incentive Math Plays Out
The structure\'s flaws surfaced in exactly the order the incentives predicted. Sponsors facing deadlines paid rich prices for whatever was available, electric vehicle startups, flying taxi companies, space ventures, many with projections but no products. The hedge funds redeemed their cash and left, meaning the actual money delivered to targets was often a fraction of the trust. And post merger shareholders, the only party whose returns depended on the business, inherited companies burning cash at valuations set in the most forgiving market ever. Nikola, an electric truck SPAC once worth more than Ford, became the emblem when its founder was convicted of fraud after, among other things, a promotional video showed a truck rolling downhill in neutral.
Regulators arrived mid party. In April 2021 the SEC issued accounting guidance requiring most SPAC warrants to be treated as liabilities and restated, a technical change that froze issuance almost overnight, and later rules stripped away the safe harbor that had allowed rosy projections. By 2022, with rates rising and speculative appetite gone, redemption rates on pending deals routinely exceeded 90 percent, and hundreds of SPACs simply returned their trusts and dissolved.
The Scorecard From 2026
The aggregate performance of companies taken public by SPAC in the boom is among the worst of any asset cohort of the decade, with the median deal losing most of its value from the 10 dollar baseline. A handful of real businesses, DraftKings among them, used the route successfully and survive today, which matters because it shows the structure itself is a tool, not a fraud. The mania was not the tool, it was the pricing, the deadline pressure, and the projections. SPACs still exist in 2026, in smaller numbers, with tighter rules and sponsors who accept more accountability, which is roughly the epitaph of every financial innovation that gets ahead of its incentives.
The Bottom Line
SPAC mania was an incentive design lesson conducted with 250 billion dollars of real money. A structure that paid sponsors for closing, let hedge funds ride for free, and marketed projections to retail produced exactly what it was built to produce, hundreds of mergers and very little value. Before joining any hot financial product, trace who gets paid, when, and for what. The SPAC boom is the decade\'s cleanest proof that the diagram of incentives is the forecast.
