SPAC 4.0: Is This Time Different? (Probably Not)

After the catastrophic collapse of 2022-2023, SPACs are staging a quiet comeback. In 2024, 57 SPAC IPOs raised $9.7B. In 2025 (year to date), 100 SPACs have raised $20.8B. The numbers are a fraction of the 2021 peak — 613 IPOs and $162.5B — but the trend is unmistakable. SPACs are back.

The question is whether "SPAC 4.0" has fixed the problems that made SPAC 3.0 a disaster. The answer, based on the structural evidence, is almost certainly no.

What's Changed

Lower volumes: The days of 613 SPACs in a single year are over. Current volumes are roughly 10% of the 2021 peak. This means less competition among SPACs for targets, which should theoretically improve deal quality.

SEC regulations: The 2024 rules eliminated safe harbor for projections, enhanced disclosures, and increased liability for misstatements. New SPACs operate under stricter rules than the 2020-2021 vintage.

Modified promotes:Some newer SPACs have reduced promotes to 10-15% or tied them to performance milestones. A few have adopted "earnout" structures where the sponsor only receives full promote shares if stock price targets are met.

Smaller trust sizes: New SPACs tend to be smaller, raising $100-300 million instead of the $500M+ mega-SPACs of 2021. Smaller trusts mean smaller absolute losses if deals go wrong.

What Hasn't Changed

The promote still exists: Even at 10-15%, the sponsor promote creates the same fundamental incentive problem. The sponsor still profits from closing any deal, and still has negligible capital at risk relative to the potential gain.

The adverse selection problem:Good companies still prefer traditional IPOs. The companies that choose SPACs still tend to be those that can't survive traditional underwriting scrutiny.

Bank incentives: Underwriting fees are still structured with deferred components contingent on deal completion. Banks still profit from closing deals regardless of quality.

Redemption dynamics: Institutional investors still use SPACs primarily as arbitrage vehicles, collecting risk-free returns and redeeming at merger. Retail investors still bear the risk of post-merger declines.

Retail targeting: SPACs are still marketed to retail investors through social media, celebrity associations, and thematic narratives.

The Historical Pattern

This isn't the first SPAC "comeback." The SPAC market has gone through multiple boom-bust cycles:

Each cycle follows the same pattern: a period of modest, somewhat functional SPAC activity; escalating volumes as success stories attract more sponsors; a mania phase where quality deteriorates and losses mount; a crash; and a quiet rebuilding that eventually starts the cycle again.

What Would Need to Change

For SPACs to genuinely work for investors, several structural changes would be needed:

1. Eliminate or cap the promote at 5% and tie it entirely to post-merger stock performance over 3+ years.

2. Require sponsor co-investment of at least 5-10% of the trust size, with a multi-year lockup. Skin in the game.

3. Independent fairness opinions from advisors without contingent compensation. No more banks opining on deal fairness while collecting deferred fees.

4. Mandatory institutional co-investment where institutional investors must commit to hold through the merger, not just provide liquidity.

5. Extended holding periods for all insider shares — sponsor, PIPE, and target company management — of at least 2-3 years post-merger.

None of these reforms have been implemented. The SPAC 4.0 structure is incrementally better than SPAC 3.0, but the fundamental incentive misalignment remains.
