Global Space Economy Market Size for 2025 Splits $429B to $648B Across Trade and Analyst Trackers

Space · 2026-08-14 10:12

Five independent trackers of the 2025 global space economy diverge by more than 50 percent on its dollar value. The Satellite Industry Association's 29th Annual State of the Satellite Industry Report -- a bottom-up survey of actual commercial, government, and infrastructure revenue conducted by BryceTech -- puts 2025 global space economy revenue at $429 billion, up 3% year-on-year. Market-research firms using top-down CAGR-based forecasting models report meaningfully higher figures for the same year: Global Market Insights at $439.1 billion, Market.us at $449.3 billion, Orbital Radar's aggregated dashboard (citing Novaspace, Space Foundation, McKinsey, and Payload) at $626 billion, and Fortune Business Insights at $648.43 billion. The roughly $219 billion spread between the lowest and highest 2025 estimate is not noise -- it reflects two structurally different measurement approaches (audited/surveyed revenue vs. modeled market sizing) that get quoted interchangeably in press coverage of 'the space economy.'

Findings

  • The Satellite Industry Association's 2025 figure ($429B) is a bottom-up survey of actual commercial satellite, launch, and ground-segment revenue conducted by BryceTech -- commercial satellite revenue alone was $303B, 71% of the total.
  • Four market-research firms using top-down CAGR modeling report 2025 space economy values 2-51% higher than the SIA survey figure: GMI ($439.1B), Market.us ($449.3B), Orbital Radar's multi-source dashboard ($626B), and Fortune Business Insights ($648.43B).
  • All trackers agree directionally that the space economy is growing at a mid-single-digit to high-single-digit annual rate, but the absolute base year value they compound from differs by up to 51%, which propagates into very different forward-year forecasts.
  • The widest gap sits between the two methodologies, not within either camp: the two market-research CAGR-model firms with figures near $440-450B disagree with the two closer to $620-650B by nearly as much as either disagrees with the SIA survey figure.
