SpaceX has earmarked 30% of the offering for retail investors — roughly $22.5B worth. This is unprecedented for a deal this size. The mechanics: participating brokers (likely Robinhood, Fidelity, Schwab) will receive allocation from the syndicate. Express interest with your brokerage now — availability is first-come, first-served at the offering price. This is the only way to buy at the IPO price, not the opening market price.

  Elon Key-Man Risk

  SpaceX's valuation is inseparable from Musk's operational involvement. A distraction — regulatory, personal, or political — could compress the multiple. The S-1 will be required to disclose key-man provisions, but there's no structural protection beyond what's disclosed.
• 🏛️
  SEC Scrutiny on xAI Merger Valuation

  Merging two privately-held entities ahead of a public offering at these valuations is unusual. Expect SEC comment letters specifically on how xAI was valued, how goodwill is treated, and related-party disclosure requirements. Could delay effectiveness by 3-6 weeks.

  Starship Commercial Milestone Risk

  Multiple forward revenue projections in the S-1 will be tied to Starship commercial launch cadence. A failure or significant delay between S-1 filing and listing day could require material amendment and investor re-education — potentially repricing the deal downward.
• 📊
  Valuation at $1.75T Has No Comp

  There is no public comparable at this scale in the aerospace/tech hybrid category. Institutional investors will apply both DCF and precedent transaction analysis. The multiple compression risk is real if public market investors disagree with the private valuation established pre-IPO.
• 🌍
  Geopolitical Government Contract Dependency

  A significant portion of revenue is U.S. government contracts (NASA, DoD, NRO). A change in administration policy, contract award protest, or international sanction scenario affecting Starlink could materially impact revenue visibility.

If SpaceX (Starlink specifically) can demonstrate four quarters of profitability in its IPO financials, it may be eligible for expedited inclusion review as early as Q3 2026. A $1.75T company added to the S&P would require index funds and ETFs tracking it to buy an estimated $40–80B in SpaceX shares — creating a structural demand surge independent of organic investor interest. This would be the largest single S&P inclusion impact in history.

Standard underwriter fee on a deal this size: 1.5–2.5% of gross proceeds. At $75B raised, that's $1.1–1.9B in underwriter fees — among the largest in history. Both banks have managed the two largest IPOs ever. Neither has managed anything close to this scale simultaneously.
