## What it is

A Special Purpose Acquisition Company (SPAC), also called a blank-check company, is a shell corporation with no operating business. It goes public on a US exchange, typically Nasdaq or the New York Stock Exchange, at US$10 per unit, with proceeds held in a trust account. The sponsor then has a fixed window to identify and acquire a private company in a transaction called a de-SPAC merger. Shareholders who dislike the chosen target may redeem at US$10 plus interest before the deal closes; if no deal closes in time, the trust dissolves and shareholders are refunded. The sponsor receives 20 per cent of post-IPO shares, known as the "promote", at near-zero cost, creating a structural incentive to close a deal regardless of terms. PIPE investors (private investment in public equity) often supply additional financing at the de-SPAC stage. Key players: sponsors (typically former executives or fund managers), growth-stage private companies as targets, underwriting banks, and institutional PIPE funds.

## History

David Nussbaum of GKN Securities underwrote the first thirteen SPACs in 1993 and 1994, designing the vehicles to comply with US SEC Rule 419, which had barred blank-check penny stocks from exchange listings. GKN was later fined US$725,000 by the National Association of Securities Dealers for overcharging investors. The structure remained a niche of roughly 60 deals per year through the 2010s.

COVID-era zero-interest-rate conditions triggered the SPAC 3.0 explosion: 248 SPACs raised US$83 billion in 2020; 613 raised US$162 billion in 2021, representing 64 per cent of all US IPOs that year. High-profile de-SPAC mergers brought DraftKings, Lucid Motors, Virgin Galactic, and Opendoor to market. Performance was dismal. By 2023, 75 per cent of listed SPACs were trading below their US$10 issue price, and de-SPAC stocks had lost an average of 67 per cent of value from their merger price. Yale Law professor John Morley noted the pattern replicated 1920s closed-end fund collapses driven by the same double-dip fee structure.

## Current state

The US SEC adopted final SPAC rules on 24 January 2024, effective 1 July 2024, by a 3-to-2 vote. The rules mandate disclosure of dilution, conflicts, and sponsor compensation in SPAC IPOs and de-SPAC mergers, and strip SPACs of the Private Securities Litigation Reform Act of 1995 safe harbor for forward-looking projections, exposing optimistic target forecasts to the same litigation risk as traditional IPO disclosures. SPAC IPO volume stabilized at approximately 57 in 2024, near the pre-boom 2019 level of 59. A SPAC 4.0 cohort has emerged with performance-tied sponsor compensation, extended deal windows of 30 to 36 months (up from 18 to 24), and higher target quality bars, including minimum US$50 million revenue thresholds. The US traditional IPO market recovered in parallel: 354 equity offerings in 2025 raised more than US$47 billion. SPACs remain a secondary path, not the dominant channel.

## Relationships

SPACs give venture capital and private equity sponsors a liquidity option for portfolio companies not yet profitable enough to sustain a traditional IPO roadshow. The US Federal Reserve's interest-rate stance directly shapes SPAC economics: near-zero rates in 2020 to 2021 pushed investors into speculative vehicles; rising rates from early 2022 both raised trust redemption yields (making inaction attractive for shareholders) and compressed growth-stock multiples. Singapore Exchange and Abu Dhabi Securities Exchange have introduced SPAC frameworks, creating non-US alternatives if the SEC's 2024 rules raise costs further. Neither [Quantinuum's June 2026 Nasdaq listing](/zh/n/quantinuum-ipo-2026) nor [OpenAI's planned 2027 IPO](/zh/n/openai-ipo-2027-tender-2026) used a SPAC vehicle; both chose traditional underwritten offerings, reflecting the reputational constraints the structure now carries.

## What to watch

Whether the SPAC 4.0 cohort's post-merger track record through 2026 to 2027 validates the reformed sponsor-compensation model or repeats earlier cycles. The SEC's 2024 rules face legal challenges, and any narrowing by US federal courts would loosen disclosure requirements. Pre-revenue AI infrastructure companies remain natural SPAC targets given their capital intensity and long profitability horizons. The sponsor promote model is under pressure from a growing minority of 2025 and 2026 SPACs launching with reduced or deferred promotes to win institutional demand.
