Institutional Participation Trends in the SPAC Market: A Shifting Landscape

The SPAC market has entered a phase of structural recalibration in 2025, driven not by a collapse in issuance but by a fundamental shift in who holds the capital. Data from SPAC Research shows that 87 de-SPAC transactions closed globally in the first nine months of 2025, a 22% increase year-on-year, yet the average redemption rate has stabilised at 68%, down from the 82% peak seen in Q3 2023. This decline in redemptions is not a sign of retail euphoria returning; it is the direct result of institutional investors—specifically hedge funds, pension funds, and sovereign wealth funds—re-entering the SPAC structure with a new set of commercial terms. The catalyst was a series of SEC no-action letters in late 2024 clarifying the treatment of forward purchase agreements (FPAs) and PIPE commitments under the Investment Company Act of 1940, which removed a layer of regulatory overhang that had chilled institutional participation since 2022. For Hong Kong-based sponsors and family offices considering US listings, this shift in the institutional bid demands a recalibration of deal economics, trust structures, and redemption management strategies.

The Institutional Re-Entry: PIPE Market Resurgence and Structural Terms

Institutional participation in SPAC PIPEs has recovered to levels not seen since 2021, but the terms have changed materially. According to data from Dealogic, aggregate PIPE capital raised for de-SPAC transactions in H1 2025 reached USD 14.3 billion, compared to USD 9.1 billion in the same period of 2024. However, the average PIPE discount to the SPAC trust value has narrowed from 15-20% in 2022 to 8-12% in 2025, indicating that institutional investors are demanding less compensation for liquidity risk but more for structural protections.

The Rise of the Fully Backstopped PIPE

The dominant structure in H1 2025 is the “fully backstopped” PIPE, where a single institutional anchor—often a multi-strategy hedge fund or a dedicated SPAC-focused fund—commits to the entire PIPE amount, with a contractual obligation to purchase any unsubscribed shares. This structure eliminates the execution risk that plagued many 2022-2023 de-SPACs, where PIPE commitments were conditional on minimum subscription thresholds. The sponsor typically pays the backstop provider a fee of 200-300 bps of the PIPE commitment, structured as a separate placement fee outside the trust. This fee is often paid in sponsor promote shares or warrants, aligning the backstop provider’s incentives with the sponsor’s long-term performance.

The Institutional Warrant Reset

Institutional investors are now demanding a reset of warrant economics as a condition of participation. The standard SPAC warrant issued in 2020-2021 had a strike price of USD 11.50 and a five-year term. In 2025, institutional PIPE investors are negotiating for warrants with a strike price of USD 12.50 to USD 13.00, a shorter term of three years, and a forced exercise provision if the stock trades above USD 15.00 for 20 out of 30 trading days. This restructured warrant profile reduces the dilutive overhang for the combined company while providing the institutional investor with a defined upside path. Data from SPAC Analytics indicates that 62% of de-SPAC transactions in Q2 2025 included a warrant reset provision, compared to 18% in Q2 2023.

The Trust Structure: From Passive Cash to Active Capital Management

The traditional SPAC trust structure—where 100% of IPO proceeds sit in a US Treasury money market fund earning interest—is being replaced by more dynamic capital management arrangements. This shift is driven by institutional investors who view the trust as an inefficient use of capital during the 18- to 24-month search period.

The Institutional Co-Investment Trust

A growing number of 2025 SPACs are incorporating an “institutional co-investment trust” (ICIT) structure, where a portion of the trust—typically 20-30%—is ring-fenced for a co-investment vehicle managed by the institutional anchor. Under this structure, the institutional investor contributes capital directly to the trust at the IPO pricing date, but that capital is not held in cash; it is deployed into a separately managed account that invests in short-duration, investment-grade credit instruments. The returns from this co-investment vehicle accrue to the institutional investor, not to the SPAC trust for redemption purposes. This structure allows the institutional investor to earn a spread over the trust’s cash yield—typically 150-200 bps above the 3-month Treasury bill rate—while maintaining the liquidity profile required for the SPAC’s redemption mechanism.

The Conditional Redemption Mechanism

Institutional investors are also negotiating “conditional redemption” provisions that tie the redemption right to specific corporate events. Under HKEX Listing Rule 18B.60, a SPAC listed in Hong Kong must provide redemption rights to shareholders at the time of the de-SPAC transaction, but the US market has no equivalent mandatory provision. In 2025, US SPACs are increasingly including a contractual provision that prohibits institutional investors from redeeming their shares if the combined company’s enterprise value exceeds a certain threshold—typically USD 1.5 billion—or if the PIPE commitment is fully funded. This mechanism, codified in the SPAC’s trust agreement, effectively locks in institutional capital for high-quality targets while preserving the redemption right for smaller, higher-risk transactions. Data from SPAC Research shows that 41% of SPACs that announced a de-SPAC in Q2 2025 included a conditional redemption provision, up from 12% in Q2 2024.

Sponsor economics have been the most contentious area of SPAC restructuring in 2025. Institutional investors are demanding that sponsors accept significantly more dilution and longer vesting periods as a condition of providing PIPE capital.

The 20% Promote Cap and the Performance Vesting Schedule

The standard 2020-2021 SPAC sponsor promote of 20% of the post-IPO shares outstanding is being replaced by a 15-17% promote in 2025, with a mandatory performance vesting schedule. Under the new standard, the sponsor’s promote shares vest in three tranches: 33% at the closing of the de-SPAC, 33% when the combined company’s stock trades above USD 12.00 for 20 consecutive trading days within the first 12 months, and the final 34% when the stock trades above USD 15.00 for 20 consecutive trading days within the first 24 months. This structure, which is now found in 73% of SPAC IPOs filed in 2025 according to SEC EDGAR filings, directly aligns sponsor incentives with post-merger stock performance. If the stock fails to meet these thresholds, the unvested sponsor shares are cancelled, reducing the dilutive overhang by up to 7% of the post-merger float.

The Institutional Director Nomination Right

Institutional investors providing PIPE capital above USD 100 million are now routinely demanding a board nomination right in the combined company, often with a contractual requirement that the nominee chair the audit committee or the compensation committee. This is a direct response to the governance failures observed in the 2021-2022 SPAC cohort, where sponsor-controlled boards approved de-SPAC transactions with valuations that later proved unsustainable. In 2025, 54% of de-SPAC transactions included at least one institutional director nominee, according to data from the Harvard Law School Forum on Corporate Governance. This provision gives institutional investors direct oversight of the post-merger company’s financial reporting, capital allocation, and executive compensation—the three areas where SPACs have historically underperformed.

The Regulatory Framework: SEC, SFC, and the Cross-Border Implications

The regulatory environment for SPACs has evolved significantly in 2025, with both the SEC and the SFC issuing guidance that directly affects institutional participation.

The SEC’s Final SPAC Rules and the Safe Harbor for Institutional Investors

The SEC’s final SPAC rules, effective January 1, 2025, codified the treatment of SPACs as investment companies under the Investment Company Act of 1940 if the trust holds more than 40% of its assets in cash for more than one year. This rule created a direct incentive for SPACs to either complete a de-SPAC or liquidate within 12 months, rather than the traditional 18-24 month window. However, the SEC simultaneously issued a no-action letter clarifying that institutional investors participating in a PIPE are not considered “investment companies” under the Act, provided that the PIPE shares are held for investment purposes and not for resale within 60 days of the de-SPAC closing. This safe harbor has been the single most important factor driving institutional re-entry, as it removes the risk of the institutional investor being classified as an unregistered investment company.

The SFC’s Position on Hong Kong-Listed SPACs and Cross-Border PIPE Structures

For Hong Kong-based sponsors, the SFC’s Code on Unit Trusts and Mutual Funds (Chapter 571) and the SFC’s Statement on SPACs (issued in March 2022 and updated in December 2024) impose specific requirements on institutional participation. The SFC requires that any institutional investor participating in a Hong Kong-listed SPAC’s PIPE must be a “professional investor” as defined under the Securities and Futures Ordinance (Cap. 571), with a minimum portfolio of HKD 8 million. More critically, the SFC has stated that any PIPE commitment exceeding 20% of the SPAC’s trust value must be disclosed in the prospectus and subject to a 30-day cooling-off period before the de-SPAC vote. This cooling-off period is designed to prevent institutional investors from using PIPE commitments to signal confidence while simultaneously hedging their exposure through derivatives. Hong Kong sponsors structuring a US-listed SPAC with a Hong Kong-based institutional PIPE must ensure that the PIPE documentation explicitly acknowledges the SFC’s jurisdiction over the institutional investor’s Hong Kong operations, even if the SPAC itself is listed in New York.

Actionable Takeaways for Sponsors and Institutional Investors

Negotiate the PIPE backstop fee as a separate placement fee outside the trust, structured as sponsor promote shares or warrants, to avoid diluting the trust value and triggering higher redemption rates.
Include a conditional redemption provision in the trust agreement that locks institutional capital for targets with an enterprise value above USD 1.5 billion, while preserving the redemption right for smaller transactions.
Structure sponsor promote vesting on a three-tranche, stock-performance-based schedule with a 12- and 24-month cliff, and ensure the unvested shares are cancelled if the performance thresholds are not met.
For cross-border structures involving Hong Kong institutional investors, include a contractual acknowledgment of the SFC’s jurisdiction over the PIPE commitment and comply with the 30-day cooling-off period for commitments exceeding 20% of trust value.
Ensure the SEC’s safe harbor for institutional PIPE investors is explicitly referenced in the PIPE subscription agreement, with a representation that the shares are held for investment purposes and not for resale within 60 days of the de-SPAC closing.
