SpaceX AI1 Orbital Data Center Costs Remain Unproven
Key insights
- SpaceX AI1 spans 70 meters with 150 kW peak compute and operates at 600 km using a 110-square-meter liquid radiator for cooling.
- Two AI1 prototypes are slated for early 2027 launches, with the Bastrop, Texas Gigasat factory targeting full operation by end of 2027.
- SpaceX IPO targets a ~$75 billion raise at a ~$1.75 trillion valuation, while Morningstar pegs fair value at approximately $780 billion.
Why this matters
SpaceX AI1 is the first serious attempt to move AI compute infrastructure to orbit, betting that solar power and vacuum cooling can offset launch and maintenance costs at scale. The gap between SpaceX's implied ~$1.75 trillion valuation and Morningstar's ~$780 billion fair value estimate signals the market is pricing in orbital AI ambition that has not yet been operationally validated. For infrastructure decision-makers, the credibility of a million-satellite AI compute constellation changes long-term supply planning, even if near-term orbital costs remain higher than terrestrial alternatives.
Summary
SpaceX unveiled the AI1 on June 8, 2026, a satellite data center with a 70-meter wingspan, 150 kW peak compute, and liquid radiator cooling at 600 km altitude.
Two prototype launches are set for early 2027, with a Gigasat factory in Bastrop, Texas operational by end of 2027. SpaceX filed plans for up to one million satellites.
Essentially: (SpaceX, Morningstar) sit far apart on what this is worth.
- SpaceX IPO targets a ~$75 billion raise at a ~$1.75 trillion valuation; Morningstar's fair value estimate is ~$780 billion.
- Anthropic reportedly pays $1.25 billion monthly and Google ~$920 million monthly for AI compute capacity.
- Ian Dahl, director of satellite engineering, detailed the 110-square-meter deployable radiator and ~70 kW/ton power density.
Whether orbital compute can beat ground-based costs remains the unresolved question underneath the entire venture.
Potential risks and opportunities
Risks
- Morningstar's ~$780 billion fair value versus ~$1.75 trillion reported valuation means IPO investors could face a steep correction if orbital compute economics fail to materialize before the 2027 launch milestones.
- Any AI1 prototype launch failure in early 2027 would push the operational Gigasat constellation back by years and undermine the IPO narrative at a critical fundraising moment.
- If orbital compute costs remain higher than terrestrial alternatives at scale, major AI compute buyers like Anthropic and Google may redirect spend to ground-based capacity and bypass the orbital product entirely.
Opportunities
- Liquid space radiator suppliers and thermal management specialists gain a high-value design reference as AI1's 110-square-meter radiator sets a new scale benchmark for orbital compute.
- Bastrop, Texas aerospace and manufacturing suppliers gain a significant long-term anchor with the Gigasat factory targeting end-of-2027 operations.
- Independent valuation and research firms willing to publish rigorous cost models for orbital compute gain credibility as SpaceX's IPO forces the $780 billion versus $1.75 trillion question into public markets.
What we don't know yet
- Whether the reported Anthropic and Google monthly compute payments cited in the article are for SpaceX orbital capacity or existing terrestrial infrastructure used as demand context.
- No public cost-per-kWh or cost-per-FLOP comparison between AI1 orbital compute and ground-based hyperscaler rates has been disclosed.
- Whether the Gigasat factory in Bastrop can scale toward the filed million-satellite constellation before terrestrial power and cooling advances close any potential competitive gap.
