Space-based data centers become economically viable at ~$200-300/kg launch costs; currently at ~$1,000/kg with Falcon 9, creating 3-5x cost gap closure opportunity

“There was a tipping point when launch costs come down to about $200 to $300 a kilogram. In principle, it was going to get cheaper to put it in space than on the ground...About $1,000 a kilogram is the cost of a Falcon 9, reusable Falcon 9. So we're about three or five X off.”
Why it matters
Launch cost economics are the primary constraint blocking the shift of compute infrastructure to space. The 3-5x gap to profitability suggests a 3-5 year window before space-based data centers become cost-competitive.
Investment implication
Companies enabling lower launch costs (SpaceX, Blue Origin, emerging launch providers) are critical bottlenecks. Once costs hit $200-300/kg, demand for launch capacity, satellite compute hardware, and space-qualified electronics will surge dramatically.
