TL;DR¶
SpaceX's S-1 IPO filing reveals Starlink has 10.3M paid subscriptions (doubled YoY from 5M), generated $11.3B revenue in 2025 (+50%), with $4.4B operating income (+120%). ARPU fell to $66/mo (from $86) due to international expansion and cheaper plans. Starlink now accounts for 60% of SpaceX's total $18.7B revenue, though SpaceX overall posted a $4.9B net loss. Terminal costs are down 59% since 2022. Starlink Mobile (direct-to-cell) has 7.4M monthly devices across 30 countries. Total addressable market: $870B for Starlink, $26T for AI enterprise.
Subscriber Numbers¶
- 10.3 million paid subscriptions in Q1 — 105% YoY growth from 5M
- Definition: a "unique Service Line" assigned to a Starlink.com account (Residential, Roam, Local Priority, Global Priority)
- Excludes managed enterprise and government customers (aviation, maritime, land mobility, fixed sites, government entities)
- Note: one household/business can have multiple service lines, so this is not equivalent to individual customers
Financials¶
| Metric | Value | YoY Change |
|---|---|---|
| Starlink Revenue (2025) | $11.3B | +50% |
| Starlink Operating Income (2025) | $4.4B | +120% |
| Connectivity share of SpaceX revenue | 60% | — |
| Total SpaceX revenue (2025) | $18.7B | — |
| ARPU (Q1) | $66/mo | Down from $86 |
| Q1 connectivity income | $1.19B | Up from $1.03B |
| SpaceX net loss (2025) | −$4.9B | — |
SpaceX is not profitable overall despite Starlink's strong segment performance — likely due to Starship R&D expenditure, explaining the need for an IPO.
Cost & Performance¶
- 59% reduction in average manufacturing cost of a Starlink Kit since 2022
- Median peak‑hour download speed: 225 Mbps globally (vs US fixed broadband median of ~129 Mbps per Ookla)
Starlink Mobile (Direct-to-Cell)¶
- 7.4 million monthly unique devices across ~30 countries via partner carriers (e.g. T‑Mobile)
- $632 million revenue in 2025
Assets & Scale¶
- $12.9 billion in satellite assets
- ~9,600 satellites in the current constellation
Addressable Markets & Future Plans¶
- Starlink TAM: $870 billion
- AI enterprise TAM: $26 trillion — SpaceX sees this as a far larger opportunity
- Next major project: orbiting data centers to support AI compute demand
Key Takeaway¶
The S-1 filing provides the first rigorous look at SpaceX's most valuable business unit. Starlink is growing fast and profitable on a segment basis, but the parent company's heavy R&D spending (presumably Starship) keeps it unprofitable overall — explaining the IPO push. The ~$12.9B satellite asset base and 9,600-satellite constellation represent a formidable moat that competitors will struggle to replicate.
