The commercial space economy was roughly 613 billion dollars in 2024 and is projected to roughly triple to 1.8 trillion dollars by 2035, growing almost twice as fast as global GDP (World Economic Forum and McKinsey, April 2024). The growth is not mostly about rockets. The WEF and McKinsey project that more than 60 percent of 2035 demand comes from industries that consume space-enabled data and connectivity (supply chain, defense, food, retail, digital communications) rather than from the launch-and-satellite backbone itself. The enabling shift underneath all of it is reusable launch: the cost of reaching orbit fell by roughly an order of magnitude over the past decade, and in 2025 SpaceX flew 165 Falcon missions, more than the rest of the world combined, while global orbital launch attempts reached about 320, up from 114 in 2020 (planet4589, SpaceNews).

Cheap launch turned space into a set of recurring-revenue businesses: satellite broadband (Starlink passed 12 million customers on June 4, 2026), earth observation sold as subscription data and analytics rather than one-off images, and now direct-to-cell connectivity to ordinary phones. The investible tension is structural. The two dominant players, SpaceX and Blue Origin, are private, so public investors access the theme through a younger and much smaller cohort of pure-plays whose FY2024 revenue ranges from Iridium's mature 831 million dollars down to AST SpaceMobile's pre-commercial 4 million dollars. The opportunity is real and durable. The public on-ramp is narrow, government-dependent, and for several names still pre-revenue.

The public universe sorts into archetypes with very different economics and risk. This is framing, not stock picking.

1. Mature cash generator (Iridium, IRDM). About 831 million dollars of FY2024 revenue, profitable, and returning capital. A lower-beta way to own established satellite communications, voice, and IoT rather than the growth frontier.

2. Launch and space systems (Rocket Lab, RKLB). About 436 million dollars FY2024, scaling the larger reusable Neutron rocket on top of a growing space-systems business. The closest public analog to owning launch capacity directly.

3. Space infrastructure (Redwire, RDW). About 304 million dollars FY2024. A picks-and-shovels supplier of solar arrays, structures, and in-space manufacturing that has expanded into defense via the Edge Autonomy acquisition.

4. Earth-observation data (Planet Labs PL, BlackSky BKSY). About 244 million and 102 million dollars respectively. Recurring imagery and analytics businesses tied closely to government and defense demand, increasingly international.

5. Lunar and exploration (Intuitive Machines, LUNR). About 228 million dollars FY2024, driven by NASA contracts. Milestone-binary: revenue and sentiment swing on individual lunar missions.

6. Direct-to-cell optionality (AST SpaceMobile, ASTS). Pre-commercial with minimal revenue but a very large addressable market. A deployment-and-execution story where the question is whether the constellation comes online on schedule.

7. The private giants (SpaceX, Blue Origin). Dominant in launch and broadband. Tracked here only for competitive context, because they frame every public competitor's economics even though you cannot buy the equity.

Cross-cutting framing: mature and cash-generative (Iridium) versus growth and pre-revenue (AST SpaceMobile, Intuitive Machines); heavily government-exposed (BlackSky, Planet, Intuitive Machines) versus more commercial; and capital-light versus capital-intensive. The right question is rarely a head-to-head ticker comparison. It is what return on capital each can earn given SpaceX's scale and its own funding position and end-market exposure.
