SpaceX S-1: Starship Reusability Not Needed for Starlink

- SpaceX's S-1 filing acknowledges for the first time that full reusability of Starship is not necessary to launch the next generation of Starlink satellites, though the filing notes that without reusability, launch costs will be higher.
- Tim Farrar, a satellite market analyst, warned that without Starship reusability, launch costs could run as much as $100 million per flight, roughly $1,000 per kilogram, while tempo remains constrained by second-stage manufacturing and first-stage refurbishment rates.
- SpaceX's third Starship test flight encountered issues relighting Raptor engines on both the booster and the upper stage — the maneuver required for controlled reentry and reuse — though the vehicle did deploy dummy satellites and two test payloads.
- Starlink's average revenue per user fell from $99 in 2023 to $66 in the first quarter of 2026, as SpaceX expanded into international markets where it cannot charge developed-economy prices, and new-user ARPU continues to decline.
- Starlink subscriber growth crossed 10 million users but the quarterly growth rate fell during Q1 2026, making Quilty Space's projection of 16.8 million subscribers by year-end dependent on roughly doubling the current growth rate.
- Amazon's Leo network is approaching the scale needed to compete with Starlink, though it is awaiting an FCC extension on a July deadline requiring it to launch 1,600 internet satellites.
- SpaceX's capex treadmill is visible in the filing: the company must replace roughly a fifth of its Starlink satellites annually and has invested $11.4 billion in the satellite business since 2023 versus $8.4 billion in Starship and launch infrastructure.
Why it matters: Starlink now accounts for the bulk of SpaceX's $11.4 billion in annual revenue, yet its growth rate is decelerating and per-user revenue has dropped 33% since 2023. If the new generation of Starlink satellites launches on expendable Starships at up to $100 million per flight, SpaceX's path to the cheap-launch economics underpinning Musk's lunar and orbital-data-center ambitions narrows considerably — and a slowing market leader signals trouble for the entire space-broadband thesis.
