How this 2028 SPCX forecast is built
Every SPCX price target on this page comes from a sum-of-parts DCF: launch services, Starlink, Starship cargo, AI1 orbital compute, and defence/national-security contracts. Each segment has its own revenue trajectory, margin curve and discount rate, and the base case blends them at probability-weighted terminal multiples.
The base case for 2028 sits at $260. The bull case ($360) requires flawless Starship cadence and AI1 monetisation ahead of consensus. The bear case ($180) prices in Starship delays, Starlink ARPU compression from LEO competition, and a market-wide multiple de-rate.
Segment assumptions
The material drivers:
- ▸Starlink: subscribers, ARPU, gross margin, capex per satellite
- ▸Starship: flights per year, payload per flight, $/kg to LEO
- ▸AI1: MW deployed, effective GPU-hours sold, downlink capacity
- ▸Launch services: commercial + national security manifest
What breaks the base case
Two things sink the base case fastest: a Starship mishap that delays commercial cargo by 18+ months, or Starlink ARPU compression as regional LEO competitors go live. Both are trackable in real time — every Starship IFT and every quarterly Starlink subscriber print re-prices the model.
The upside path is symmetrical: sustained Starship cadence and AI1 hitting first commercial milestones both compress the risk premium and push SPCX towards the bull case.
Key takeaways
- 2028 base case: $260; bull $360; bear $180
- Model each segment separately — SPCX is not one business
- Track the operational catalysts, not chart patterns
