SpaceX IPO: Full Institutional Underwriting Framework

SpaceX is an extraordinary strategic asset with real launch scale, a profitable Starlink/Connectivity engine, and rare optionality across Starship, direct-to-device connectivity, government services, terrestrial AI compute, and long-dated orbital AI infrastructure. The public-market setup remains demanding: a reported $1.75 trillion valuation would require investors to underwrite not only Connectivity's current profitability, but also Starship execution, AI infrastructure profitability, disciplined capital allocation, and durable founder-led execution across several capital-intensive domains. The S-1 makes the debate sharper: Connectivity generated $11.387 billion of 2025 revenue and $4.423 billion of operating income, while AI generated $3.201 billion of revenue, a $(6.355) billion operating loss, and $12.727 billion of capex. Consolidated operating cash flow was positive at $6.785 billion in 2025, but PPE purchases were $20.737 billion, and Q1 2026 capex accelerated to $10.107 billion. The note should therefore be valued as a segmented infrastructure and option-value underwriting exercise, not as a simple high-growth technology IPO. Additional diligence priorities are deal mechanics and technical demand, AI contract durability and supply-chain bottlenecks, Musk-ecosystem related-party cash flows, and a capital-commitments/use-of-proceeds waterfall.
