Musk predicts orbital compute will outpace Earth's by end of 2028 as SpaceX targets 1M tons to orbit
XFreeze · x · 2026-10-31
Elon Musk predicts that new orbital compute deployed each month will surpass new terrestrial compute around the end of 2028, and far exceed it in 2029. XFreeze argues this isn't wishful thinking — SpaceX's own roadmap is built around it.
Key numbers
- SpaceX launched 2,200 tons to orbit in 2025, over 80% of humanity's total upmass
- Official path: 167,000 tons in 2028, 740,000 tons in 2029, over 2 million tons/year by 2032; Musk says "a million tons to orbit per year in about three years"
- Starship V3 is designed for 100 tons per launch (200 tons expected with V4); cost per kg has fallen from $18,500 to $2,700 on Falcon 9, with Starship targeting a >99% cut
- At 100 kW per ton, a million tons/year of SI satellites adds 100 GW of orbital compute annually — with near-continuous solar power and radiative cooling, no grid queues, land fights, or cooling towers
- For scale, SpaceX's entire ground fleet is expected to pass only 3 GW this year
