How Much Did the Bankers Actually Make on the SpaceX IPO?
CJ Gustafson's primary-research read of SpaceX's 424B4 prospectus (the vFinal amendment to the S-1), focused entirely on underwriting fee structure. Paired with the recurring weekly SaaS valuation/efficiency data section (9 peer groups, sourced from Koyfin).
⚠️ Sponsorship
Abacum (third-party paid sponsor): FP&A/financial planning software. Promoted a whitepaper on AI in FP&A. Standard enterprise software sponsor for a CFO/finance audience — bias is commercial, not editorial, but positions Abacum as the "AI-native FP&A" frame throughout. Koyfin appears as a data partner/affiliate link in the recurring metrics section — not a paid editorial sponsor but a referral relationship.
Why this is in the vault
SpaceX raised $75 billion in the largest IPO on record — and negotiated the underwriting commission down to a 0.67% gross spread, far below the 4–5% typical for raises in the $500M–$1B range. CJ walks through the math directly from the prospectus: the total fee pool was $500 million (a deliberately round number), with Goldman Sachs and Morgan Stanley each holding 20% allocations (~$100M each pre-greenshoe).
The key structural move: SpaceX zeroed out the per-share commission on greenshoe (over-allotment) shares entirely. Banks distributed an extra ~$11 billion of stock and collected nothing on it. That drops the effective spread from 0.67% to 0.58% — less than most retail financial advisor fees. CJ's closing observations: this is still the largest absolute IPO fee pool ever but roughly one quarter of Goldman's entire equity underwriting revenue for a single quarter; the "real" return for the banks comes via future trading commissions from the institutional funds let into the deal; and the greenshoe zero-out is a SpaceX-only flex that has now set the pricing benchmark for OpenAI and Anthropic's eventual offerings.
The secondary half of the issue is the weekly recurring SaaS peer group data (NTM Revenue multiples, Rule of 40, Revenue per Employee, CAC Payback) across 9 categories — boilerplate template content, not unique to this issue.
Key figures:
- SpaceX gross raise (fee-bearing): $75B; total distributed including greenshoe: ~$86B
- Gross spread: 0.67% on $75B = $500M commission pool; effective spread on $86B: 0.58%
- Goldman Sachs and Morgan Stanley: 20% each ≈ $100M pre-greenshoe, ~$115M post if greenshoe had been normal
- Foregone greenshoe commission across the syndicate: ~$75M
- Goldman's equity underwriting revenue last quarter for context: ~$535M
- Typical IPO fee range at $500M–$1B raise size: 4–5%
- CoreWeave and Cerebras paid higher spreads than SpaceX on their large deals
Mapping against Ray Data Co
Medium mapping. The direct RDCO hook is the benchmarking signal, not the banking mechanics: the SpaceX deal has set a new pricing floor for mega-IPOs, which means Anthropic and OpenAI S-1 breakdowns (a known RDCO content play via Sanity Check) should include an underwriting fee section using these numbers. This is source material for the SpaceX IPO lead magnet in progress on the board.
Secondary relevance: CJ's method here — reading the 424B4 line by line and surfacing a non-obvious angle (the greenshoe zero-out) — is the exact "junior analyst IC memo" format that the SpaceX Sanity Check lead magnet is targeting. The article is a live competitive benchmark for tone and depth.
No direct data engineering / AI agents / prediction market angle.
