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):

SegmentRevenueAdj. EBITDA marginRead
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:

Structure: The Good and the Ugly

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.
