Five businesses. One ticker.
SPCX is not a launch company with a side internet bet. The 2025 income statement makes Starlink the majority of revenue and the only segment producing meaningful operating income. Falcon & Dragon is a steady cash-and-credibility engine. Starshield is a defense-margin story with limited disclosure. Starship is the $3B+ R&D bet that the company is funding through the other segments. xAI — added in the February 2026 all-stock merger — is the narrative engine. Investors are buying the whole portfolio, not picking one.
The five segments, with the headline number on each.
Starlink
The cash engine. World's largest satellite broadband network. Only segment producing meaningful operating income. ~38.6% segment op margin in FY2025.
Falcon & Dragon
The credibility engine. Falcon 9, Falcon Heavy, Crew Dragon. ~90% of global commercial launch market. NASA Commercial Crew and CRS-2 incumbent.
Starshield
Classified government constellation. NRO, USSF, DoD, allied buyers. Defense-margin profile. Disclosure narrower than other segments by design.
Starship
The $3B+ R&D bet. First commercial payload targeted H2 2026. Multiplier on Starlink V3 unit economics. NASA Artemis HLS contracted revenue line.
xAI
Added through the February 2026 all-stock merger. Combined entity valued at $1.25T at closing. Grok, the X platform, orbital AI research.
Every segment, every key number on one row.
| Segment | FY2025 revenue | FY2025 op income | YoY revenue | Disclosure depth |
|---|---|---|---|---|
| Starlink | $11.4B | $4.4B (~38.6%) | +48% | Full |
| Falcon & Dragon | $4.2B (external) | ~$0.9B | +15% | Full |
| Starshield | ~$1.8B | Redacted (high margin) | ~+80% | Narrow (classified) |
| Starship | ~$0.05B (HLS milestones) | -$3.0B (R&D) | n/m | Full |
| xAI (partial year) | ~$1.3B (11 months post-merger) | Loss (compute ramp) | n/a (new segment) | Full |
| Consolidated | $18.67B | Net loss $4.9B | +33% | — |

How each segment feeds the others.
The five segments are not independent product lines. The S-1 is explicit that vertical integration is the company's structural advantage. The flywheel:
- Falcon & Dragon launches Starlink satellites at internal cost — every other constellation has to pay a third-party launch provider (often SpaceX itself).
- Starlink generates the operating cash flow that funds Starship development.
- Starship, once operational, enables Starlink V3 deployment at materially better unit economics — and unlocks future Starshield generations and the orbital AI thesis inside xAI.
- Starshield reuses the Starlink V2 chassis but with classified payloads — fixed engineering cost is amortized across the consumer and government constellations.
- xAI (Grok) already runs Starlink network optimization, contributing to Starlink's gross margin lift. The X platform provides distribution for Starlink and xAI products.
The flywheel is real, but it concentrates execution risk: a major Starship anomaly affects four of the five segments. A Falcon stand-down affects Starlink deployment, Starshield launches, and external commercial revenue simultaneously.
