The thing that has happened to the global space economy over the past 25 years is the kind of phenomenon that is easier to see in retrospect than to recognise while it is occurring. In 2000, the entire global space industry generated approximately $130 billion in annual revenue, almost all of it from government programmes and satellite communications. By 2023, the figure had reached approximately $630 billion. By 2035, on the most widely-cited forecast available, it is projected to reach $1.8 trillion — making space comparable in economic scale to the current global semiconductor industry, and substantially larger than the global pharmaceutical industry. The growth is occurring above the cloud line, mostly out of sight of the populations whose lives are being increasingly shaped by it, and at a pace that exceeds essentially any other major economic sector currently being tracked by long-range forecasters.
According to the World Economic Forum’s April 2024 announcement of the $1.8 Trillion Opportunity report developed with McKinsey & Company, the central finding of the analysis is that the bulk of the space economy’s growth between now and 2035 will not come from rockets, exploration missions, or moonwalks. It will come from terrestrial industries that have begun to depend, in fundamental but mostly invisible ways, on satellite-enabled services. Earth observation. Satellite communications. Positioning, navigation, and timing services. Weather forecasting. Supply-chain tracking. These are the categories projected to drive the substantial majority of the new value, and the industries most affected are not aerospace companies but supply-chain and transportation firms, food and beverage producers, retail chains, insurance companies, and the digital communications sector — none of which traditionally classified themselves as space companies, and most of which will not be aware of how dependent their operations have become on orbital infrastructure until something disrupts it.
The two halves of the space economy
Per McKinsey’s overview of the space economy structure, the field can be usefully divided into two distinct halves. The first is what McKinsey calls “the backbone” — the satellites, launchers, ground stations, and physical infrastructure that constitute the traditional space industry. This category includes SpaceX, Blue Origin, Rocket Lab, the various government space agencies, satellite manufacturers, and the companies that build and operate the orbital and ground hardware. The second half is “the reach” — the much larger ecosystem of applications, services, and businesses that depend on the backbone to deliver value to end users on Earth. Ride-hailing apps that rely on GPS satellites. Agricultural operations that use Earth-observation imagery for crop management. Logistics companies that track shipments via satellite. Climate monitoring services. Financial-services firms that use satellite-derived timing signals for high-frequency trading.
The growth projection puts most of the new value in the reach rather than the backbone. The McKinsey-WEF analysis specifies that traditional hardware and service providers will see their share of the total space economy slowly decrease over the next decade, while the reach grows substantially faster than the backbone. The implication is that the space industry of 2035 will look substantially different from the space industry of today — not because the rockets and satellites will be radically different, but because the population of companies and customers depending on them will have expanded across nearly every major sector of the global economy.
What is real versus what is aspirational
The drivers that have attracted the most popular attention — asteroid mining, lunar resource extraction, helium-3 fusion fuel, space-based manufacturing, orbital tourism — are largely not the drivers of the $1.8 trillion projection. They are aspirational additions to the space economy that may or may not materialise in the projected timeframe. Asteroid mining, in particular, has been promoted by various ventures over the past decade — Planetary Resources, Deep Space Industries, AstroForge — but no commercial asteroid-derived material has yet been brought to market, and the engineering and financial obstacles remain substantial. Lunar resource extraction is closer to operational reality, with NASA’s Artemis programme planning to demonstrate water-ice extraction from permanently shadowed polar craters in the 2030s, but commercial-scale lunar mining is unlikely to contribute meaningfully to the global economy before 2040 at the earliest.
What is real and immediately driving the growth is mostly less glamorous. Satellite mega-constellations are real — SpaceX’s Starlink alone has launched approximately 7,000 satellites and is on track for tens of thousands more. Amazon’s Project Kuiper, OneWeb, and several Chinese constellations are also deploying at scale. The total number of operational satellites in orbit has grown from approximately 2,000 in 2018 to more than 10,000 currently, and is projected to exceed 100,000 by 2030. Earth-observation services have matured to the point where commercial satellite imagery is now used routinely by agricultural insurance providers, commodity traders, climate scientists, and intelligence agencies. Commercial space stations, designed to replace the International Space Station when it retires in 2030, are under active development by Axiom Space, Voyager Space (Starlab), and the Blue Origin / Sierra Space joint venture (Orbital Reef). These are not science fiction. They are construction projects with timelines and financing.
What this means for the next decade
As reported by a December 2025 World Economic Forum analysis of developing economies in the space sector, the geographic distribution of space-economy growth is also shifting substantially. For most of the post-Apollo era, the global space sector was dominated by the United States and Russia, with significant activity in Europe and Japan. The picture in 2025 is more diverse. India successfully landed Chandrayaan-3 on the Moon’s south pole in 2023 — the first country to reach the south pole — and operates a substantial domestic launch industry. China’s space programme has approximate parity with NASA on several metrics and is targeting a crewed lunar landing by 2030. The United Arab Emirates has a Mars orbiter and is participating in lunar missions. Brazil, Nigeria, Mexico, and several Southeast Asian countries are building domestic satellite capabilities. The space economy is becoming, for the first time, a multipolar industry in which substantial value is generated outside the historical aerospace powers.
The structural risks to the projection are real and worth noting. The continued accumulation of orbital debris raises the long-term possibility of the Kessler syndrome — a cascading collision sequence that could render certain orbital altitudes unusable. The regulatory framework for space activity remains fragmented and inadequate to the scale of commercial activity now underway. Geopolitical tensions between the major space powers could produce export controls, technology restrictions, or worse. As covered in a 2024 Innovator analysis of the WEF/McKinsey findings, the $1.8 trillion figure is itself a base-case projection; the report’s upside scenario reaches $2.3 trillion, and the downside scenarios — in which orbital congestion, regulatory failure, or geopolitical disruption substantially slow the growth trajectory — produce significantly lower numbers. The most likely outcome is that the actual 2035 space economy lands somewhere in the broad range between these scenarios. The basic direction, however, is no longer seriously contested. Space is now an industrial sector at the scale of pharmaceuticals or semiconductors, growing faster than either, and is no longer adequately described as a frontier.
