Once considered a niche domain, the space economy is now a growing industrial force supporting innovation, new services and public policy objectives. Global space-related revenues are estimated at USD 550-600 billion in 2025, depending on scope, approaching the size of the global semiconductor industry (value at about USD 620 billion in 2024).
Space is also a measurable component of national economies. Harmonised accounts show that in the United States the sector generated USD 142.5 billion in GDP in 2023, or 0.5% of the total, as well as USD 240.9 billion in gross output and 373 000 private-sector jobs. In Italy, the second country to develop such accounts, space activities generated 0.14% of GDP, EUR 8 billion in output and more than 23 000 jobs. The OECD support countries’ measurement strategies and developing comparable space accounts.
The largest economic value lies downstream, where satellite data and services are embedded in everyday economic activity. Space-based systems support more than half of the most critical infrastructures and services across OECD countries, including transport, energy, communications, and food supply. This dependence is economically significant and in some advanced economies, close to one fifth of GDP is supported by satellite-enabled services (i.e. estimated to support around 18% of UK GDP). Satellites also provide more than 90% of the observations assimilated into weather forecasting systems.
This is amplified by greater data availability and expanding connectivity. Around 70% of data from active earth observation missions is now openly available, enabling businesses of all sizes to develop applications in agriculture, transport, finance, infrastructure management and emergency response. Satellite broadband represented only 0.7% of OECD fixed broadband subscriptions in 2023 but low-earth orbit constellations are accelerating connectivity growth by improving latency, speed and coverage.
