PRIVATE MARKETS, PLAINLY: THE NEXT FRONTIER
Ask ten people what “the space economy” is and most will describe a rocket. The rocket is real, but it is a small part of the picture. It helps to see the sector as a stack, with each layer sitting on the one below it.
At the bottom is launch: getting mass to orbit. This is the part everyone pictures, and it is the part that changed first. As reusable systems matured, the cost of reaching orbit fell sharply, and the pace picked up with it; in the first half of 2025 there was a liftoff to orbit roughly every 28 hours, by the Space Foundation’s count. Cheaper, more frequent launch is the foundation the rest of the economy is built on, because it sets the price of everything above it.
Above launch sit the assets that go up: satellites, increasingly flown in large constellations of hundreds or thousands rather than as single, expensive spacecraft. This is where much of the recent private activity concentrates, because a constellation turns space from a one-off project into an operating system with recurring capacity to sell. It is the difference between building one bridge and running a toll road.
Then comes ground infrastructure: the antennas, gateways, and terrestrial networks that make orbital assets useful. Space hardware is inert without a way to talk to it, and this layer is easy to overlook precisely because it sits on Earth. It is also where a lot of real, contracted revenue lives.
At the top sits everything the other layers enable: connectivity, data, imaging, positioning, timing, and the services built on them. This is where most end-customer money eventually shows up, and it is why the sector’s reach is wider than it looks. When a farmer checks a forecast or a bank timestamps a transaction, that is the top of the stack doing its job.
The structural story, plainly, is a shift from government to commercial. For most of its history, space was funded by national programs and built by a short list of primes. Falling launch costs and constellation economics opened room for private companies across every layer, and private capital followed. By the Space Foundation’s most recent tally, the global space economy reached about $686 billion in 2025, and the commercial share is now close to four-fifths of the total, with government spending making up the rest. A decade ago the balance leaned much more heavily on government. That rebalancing, more than any single launch, is why space now appears in private-markets conversations at all.
There is one more move worth adding to the map, because it is where the frontier is heading next: the stack is starting to extend beyond Earth orbit. As sustained activity on and around the Moon becomes a near-term goal rather than a distant one, the Moon needs the same things Earth orbit already has, communications and navigation, and it does not yet have them. Several national programs are building that layer now. NASA describes its LunaNet effort as an attempt to bring internet-like communications and navigation to the Moon, with relay satellites in lunar orbit so that assets can stay connected even where the Earth is not visible from the surface, such as the far side and the polar regions. NASA’s first lunar relay work is slated to begin around 2026, with the European Space Agency’s Moonlight and Japan’s lunar navigation effort following later this decade.
The logic mirrors the Earth stack almost exactly. A relay stationed near the Moon lets each lunar asset communicate without carrying all the power and the antenna it would need to reach back to Earth on its own, the same way ground infrastructure makes orbital assets useful closer to home. In plain terms, the frontier is no longer only about communication in orbit; it is starting to include communication at the Moon.
A caution, larger here than anywhere else on this map: this is the newest and least proven layer. It is largely pre-revenue, it depends on programs and timelines that can slip, and the economics of lunar and cislunar activity are early and unsettled. It belongs on the map because that is where serious public and private effort is now pointed, not because anyone can yet say what it is worth. The chapter on risk returns to this directly.
Our unnamed frontier company lives in the middle of this stack. It does not build rockets; it buys launch the way a shipper buys freight. Its business is the constellation and the ground network beneath it, and the connectivity and data it sells at the top. That position, buying the commodity layer and selling the service layer, is a common shape for a frontier infrastructure company, and it will matter when we get to how the business is funded and where its risks sit. Whether a company like this ever extends outward toward the Moon is a strategic question, not a given; for our purposes it stays where the revenue is today, in orbit and on the ground.
A note for readers, because this chapter is a map and not a recommendation: laying out the stack does not rank it. Each layer has different economics, different competition, and different capital needs. Launch is capital-heavy and concentrated; constellations are capital-heavy and racing; ground and services can be steadier but more contested; and the lunar layer is the least proven of all. Which layer is the better place to put a dollar is exactly the kind of question the chapters on funding and risk are meant to help you ask, not a question a map can answer.
