The Verdict, Up Front
Neutral / Avoid at the IPO price. Buy on a correction to the $90–105 range. SpaceX is a genuinely exceptional business priced for perfection and then some: the $135 offering implies a 35–40% premium to Prof. Damodaran's post-prospectus intrinsic value of $1.25–1.30T (~$100/share).

Three Businesses in One Trench Coat
SpaceX operates three segments with radically different economics (FY2025):
| Segment | Revenue | Adj. EBITDA margin | Read |
|---|---|---|---|
| Space (launch) | $4.1B (22%) | 16.0% | 80%+ launch share, ~67% gross margins, bears Starship R&D |
| Connectivity (Starlink) | $11.4B (61%) | 62.9% | The cash engine — 10.3M subscribers, +49.8% YoY |
| AI (xAI) | $3.2B (17%) | −38.6% | $(6.4)B operating loss; $7.7B capex in Q1 2026 alone |
The launch business has a moat no competitor can replicate within a decade — Falcon 9 boosters reflown up to 34 times, ~650 launches at >99% success, 9,600 satellites in orbit (~75% of all active maneuverable satellites). Starlink has telecom-like recurring economics with exceptional incremental margins. The AI segment is where the thesis strains: Grok trails ChatGPT, Claude and Gemini in enterprise adoption, while consuming the majority of the company's $20.7B capex+R&D.
Consolidated FY2025: $18.7B revenue (+33% YoY), but a $4.9B net loss and free cash flow of −$13.95B. The Connectivity segment's $7.2B EBITDA is masking an AI cash furnace.
The TAM Problem
The prospectus claims a combined addressable market of ~$28 trillion — including $26T for AI. A credible AI products/services TAM is $3–4T by 2035 (Damodaran). Buyer beware:
| Segment | Prospectus TAM | Credible TAM | Assessment |
|---|---|---|---|
| Space launch | Not specified | $100B by 2036 | Credible |
| Connectivity | $1.4T+ | $160B by 2036 | Inflated |
| AI | $26T | $3–4T by 2035 | Fantasy |
Structure: The Good and the Ugly
- Good: 100% fresh issue — no promoter or PE exit; ~$74.4B net proceeds stay in the company, earmarked for AI compute, launch infrastructure and the V3 Starlink constellation.
- Ugly: Dual-class shares give Musk ~82.4% of votes post-IPO. Minority shareholders have zero effective governance power, there is no disclosed succession plan, and the same person runs at least five major entities. Colossus is leased to Anthropic — a direct Grok competitor — for $1.25B/month.
Bottom Line
SpaceX sits at the intersection of three megatrends and two of its three businesses are extraordinary. But at $135 the IPO embeds all of that optimism and more, while attaching a governance discount the market seems unwilling to charge. The stock needs to grow into its valuation — public investors get a better entry when reality reprices the AI segment.
