What Viasat actually does vs SpaceX
Viasat (VSAT) operates in GEO broadband and mobility. Investors default to treating any listed space name as a SPCX substitute, and the tape often trades them in correlation — but the businesses are not the same and the multiples reflect very different things.
Verdict: losing share to Starlink in mobility (maritime, aviation).
Revenue mix, margins, moat
SPCX is a Starlink and AI1 story with launch as the reusable-cost engine. VSAT is GEO broadband and mobility. The overlap that matters for the P&L is narrow.
On margins, SPCX benefits from vertical integration and internal launch economics that no competitor can replicate. That is the entire defensibility of the SOTP valuation.
Which to own
For a single-name space exposure, SPCX carries the deepest optionality — Starship, AI1, Mars — but also the fattest multiple. VSAT is a cleaner pure-play on its niche and, in pair-trade terms, can hedge SPCX-specific risk (launch mishap, ARPU miss) while keeping sector beta on.
Key takeaways
- SPCX and VSAT are not substitutes — different revenue drivers
- Use VSAT as a pair-trade hedge, not a replacement
- Own SPCX for optionality, own the pure-play for the niche
