A Tiny Market Underwriting Enormous Risk
Space insurance is one of the smallest and strangest corners of the global insurance industry. Only about a dozen underwriters worldwide will take the risk, and together they collect roughly $500–600 million in premiums a year — against billions of dollars of insured value riding on rockets with single-digit failure rates. A handful of total losses can turn a profitable year into a heavy one for the entire market.
Coverage usually spans the riskiest window: launch and the first year in orbit, when most failures happen. Premiums run about 5–12% of the satellite's value, rising sharply after big losses or for an unproven rocket, and easing during loss-free stretches. The most important trend, though, is what isn't insured: mega-constellation operators like SpaceX self-insure their cheap, mass-produced Starlink satellites, and most government launches go uncovered — so even as launch rates soar, the insured share keeps shrinking.
Premium, rate and market-size figures are rounded estimates from space-insurance market reports (Seradata and broker reviews) and underwriter disclosures, in current USD; the market is small and figures move year to year with the loss record. The calculator multiplies a satellite value you set by a representative rate — it is illustrative, not a quote. Launch counts are live from Orbital Radar's launch database.
