In the current landscape (early 2026), the “money” in the satellite industry is split between two distinct but increasingly intersecting models: the high-margin, mission-driven contracts of the Space Development Agency (SDA) and the high-volume, recurring revenue of LEO constellations like Starlink.
While the SDA provides the most reliable “lump sums” for manufacturers, commercial LEO constellations have proven that a massive subscriber base is the only way to achieve truly industrial-scale revenue.
The SDA “Industrial” Model: Massive Fixed-Price Contracts
The Space Development Agency’s Proliferated Warfighter Space Architecture (PWSA) has become the single most important revenue driver for traditional and “new space” manufacturers. Unlike legacy cost-plus programs, the SDA uses firm-fixed-price contracts, treating satellites like industrial products rather than bespoke science projects.
- The Scale of Capital: In December 2025 and early 2026, the SDA finalized its Tranche 3 Tracking Layer awards, totaling approximately $3.5 billion for 72 satellites.
- Key Beneficiaries: * Lockheed Martin: $1.1 billion (Tranche 3)
- L3Harris: $843 million (Tranche 3)
- Rocket Lab: $805 million (Tranche 3) — a significant “graduation” for the firm into prime contractor status.
- Northrop Grumman: $764 million (Tranche 3)
- The SDA Rationale: The SDA “buys by the tranche” (every two years). This provides a predictable revenue “conveyor belt” for industrial-scale satellite builders who can meet the agency’s strict schedule and interoperability standards (e.g., Optical Inter-Satellite Links).
Commercial LEO Constellations: The Firehose of Recurring Revenue
If the SDA is about contracts, LEO constellations like Starlink are about cash flow. By late 2025, Starlink had moved from an experimental service to a utility-scale dominant player.
- Subscriber Growth: Starlink reported ending 2025 with 9.2 million active customers, doubling its base every 12–15 months.
- Revenue Powerhouse: * 2025 Actuals: Starlink passed the $10 billion revenue mark in 2025.
- 2026 Projections: Analysts at Quilty Space and Bloomberg project Starlink revenues will hit $15.9 billion to $24 billion in 2026.
- Vertical Diversification: The “money” is no longer just in residential $120/month plans. High-margin verticals now include:
- Maritime: Over 150,000 vessels (commercial ships pay $2,000+ per month).
- Aviation: 1,400+ aircraft added in 2025 alone.
- Direct-to-Cell: 12 million people connected to emergency/text services, with 150Mbps broadband targets set for 2027-2028.
Comparison: Where is the Better Margin?
| Metric | SDA “Industrial” Satellites | Commercial LEO (Starlink) |
| Primary Revenue | Government Contracts (Firm-Fixed Price) | Monthly Subscriptions (Recurring) |
| Individual Sat Value | ~$40M – $60M per bus | ~$250K – $500K (Estimated internal cost) |
| Revenue Stability | Extremely High (Multi-year tranches) | Variable (Churn/Expansion) |
| Customer Base | 1 (The U.S. Government) | 9M+ (Individuals, Airlines, Ships) |
| Current Market Cap/Value | Reflected in Prime stock prices | ~$200B – $400B (SpaceX valuation) |
The “Hybrid” Trend of 2026
The most significant trend this year is the blurring of these two categories. In February 2026, the SDA awarded a $30 million “HALO Europa” contract to explore using commercial constellations for tactical military communications “as-a-service.”
The Verdict: For stability and high-unit profit, the money is in SDA contracts (The “Industrial” model). For valuation and absolute scale, the money is in the subscriber-based constellations. Most successful space firms (like Rocket Lab and SpaceX/Starshield) are now aggressively pursuing both.
