Starcloud announces Bitcoin mining in orbit
Starcloud, a company that builds data centers in space, says it will start mining Bitcoin (BTC) from orbit. The plan was revealed in a video posted on September 7, 2026.
Key numbers
- Funding: nearly $500 million.
- Valuation: about $2 billion.
- One Nvidia H100 GPU has already been sent to space, but it overheats.
Technical hurdles
Mining Bitcoin requires a lot of cheap electricity. In space the cost would rise because of launch fees, the need to radiate heat, and the difficulty of servicing hardware 500 km above Earth. Radiation levels are also higher, which can damage chips.
Expert criticism
The Institute of Electrical and Electronics Engineers (IEEE) and YouTuber Real Engineering both say the idea is unrealistic. They estimate that achieving gigawatt‑scale processing would need tens of thousands of launches and a solar array about four kilometres long and one kilometre wide – far beyond current launch rates of roughly 100 per year.
Confirmed facts
- Starcloud has raised close to $500 million and is valued at $2 billion.
- The company has placed an Nvidia H100 GPU in orbit, where it cannot run at full power because of overheating.
- IEEE and Real Engineering have publicly questioned the technical feasibility of orbital data centers.
Open questions
- How much total will it cost to launch and maintain a large‑scale mining operation in space?
- Can the heat‑radiation problem be solved without prohibitive expense?
- What timeline would be realistic for achieving any meaningful mining output?
Why it matters
Bitcoin mining profit depends on low‑cost energy. If space mining were possible, it could change where miners locate their hardware. The current analysis suggests the approach would be far more expensive than Earth‑based solutions.
