Long-Horizon Capital

The Two-Hundred-Year Portfolio

The argument in brief

Most investment horizons are an accident of accounting. A quarter is a reporting convention; a year is a tax artefact; even a "long-term" private-markets fund returns capital inside a decade. But a small and unusual set of institutions genuinely thinks in generations. A sovereign wealth fund saving a non-renewable resource for citizens not yet born, a public pension paying benefits to people who will retire in 2070, an endowment chartered in perpetuity — these are the closest things capitalism has produced to a two-hundred-year owner. The question this report asks is deliberately uncomfortable: if any pool of capital should be thinking seriously about the industrialization of space, it is this one. And almost none of them are.

The off-world economy is no longer science fiction with a balance sheet attached. The global space economy was worth roughly $613 billion in 2024 and is projected by the World Economic Forum and McKinsey to reach approximately $1.8 trillion by 2035 — growth faster than global GDP, and a scale comparable to today's semiconductor industry. The master variable behind that curve is the collapse in the cost of reaching orbit, which has fallen by something close to 95% in fifteen years and may fall another order of magnitude this decade. Falling launch costs do to space what cheap bandwidth did to the internet: they convert a series of heroic, bespoke missions into an industrial supply chain.

Four frontier theses sit on top of that base. Energy: space-based solar power, demonstrated in principle and now an engineering-and-cost problem rather than a physics one, offers continuous baseload power beamed to Earth. The Moon: water ice and other volatiles at the lunar poles make in-situ resource utilization — propellant, oxygen, eventually metals — the foundation of a cislunar economy. Minerals: asteroids hold platinum-group metals in concentrations that, if ever returned economically, would dwarf terrestrial deposits and could relieve some of the environmental burden of mining on Earth. Settlement: the very long-horizon possibility that humanity becomes, in the phrase, a multi-planet species — the most speculative thesis, and the one that most directly speaks to civilizational risk and resilience.

None of this is an investment recommendation, and most of it is uninvestable today in any prudent size. The honest assessment is that the near-term opportunity is mundane and already institutional (launch, satellites, Earth observation, connectivity, position-navigation-timing), while the civilization-scale theses (orbital power, lunar industry, asteroid metals, Mars) are real but unpriced, unproven at scale, and wrapped in genuine systemic risks — orbital debris that could foreclose whole orbits, a legal regime that does not clearly recognise property in space, and a hype cycle that will strand a great deal of capital before it rewards any. The universal owner's task is therefore not to "bet on space." It is to understand a structural shift early, to size exposure for a future it has not observed, and to recognise that some of the most important questions here are about risk and stewardship, not return. This report sets out the case, the evidence, the risks, three scenarios, and a practical posture for an investment committee that takes its own time horizon literally.


I. Why a two-hundred-year owner should even ask the question

The defining feature of a universal asset owner is not size alone; it is the combination of size, diversification and duration. A fund that owns a representative slice of the entire investable economy cannot diversify away systemic risk, because it owns the system. Its returns over any meaningful horizon are determined less by security selection than by the trajectory of the whole — productivity, demographics, energy, conflict, climate, and the technological frontier. For such an owner, the relevant unit of analysis is not the asset but the civilization the asset sits inside.

That reframing is what makes the space question legitimate rather than whimsical. A pension fund with a thirty-year duration on its liabilities is, whether it acknowledges it or not, making an implicit bet on what the economy looks like in 2056. A sovereign fund explicitly chartered to convert exhaustible resource wealth into a permanent endowment for future citizens is making a bet on what the economy looks like for as long as the country exists. These are institutions whose entire reason for being is to carry value across time at a scale and patience no individual, corporation or government can match. The intellectual tradition of "universal ownership" — the recognition that the largest, most diversified funds effectively internalise economy-wide externalities — implies a corollary that is rarely drawn out: such owners have both a stake in, and a degree of influence over, the largest secular transitions of their century. The energy transition is one. The arrival of artificial intelligence is another. The extension of the economy beyond Earth is, on a long enough horizon, a third.

There is a temptation to dismiss that third item as a category error — to say that space is for venture capitalists and governments, not for the conservative stewards of retirement income. The temptation is understandable and, for the near term, largely correct on sizing. But it rests on a confusion between timing and relevance. The printing press, the railway, electrification, the container ship and the internet were each, at the moment of their infancy, uninvestable for a prudent fiduciary; each later became the substrate of the entire economy a long-horizon owner was trying to track. The universal owner's comparative advantage is precisely the ability to hold a position through the awkward decades when a transition is real but not yet remunerative. To decline even to think about the off-world economy is not prudence; it is the abdication of the one job duration was supposed to enable.

There is also a defensive logic. If the space economy compounds toward the scale its forecasters project, a fund that owns the global market index will own it anyway — passively, unintentionally, and without having thought about the specific risks it is taking. The largest beneficiaries of the next phase of space are as likely to be incumbent industrials, semiconductor firms, telecommunications networks and energy companies as they are to be pure-play rocket builders. A universal owner is therefore already long the space economy through the back door. The question is whether it understands that exposure, can identify where it is concentrated, and can recognise the system-wide risks — orbital congestion, geopolitical contest, regulatory vacuum — that could impair a large set of its holdings at once. Thinking about space, in other words, is partly just thinking clearly about a portfolio the fund already holds.


II. The off-world economy is already an asset class

It helps to separate what is real and investable today from what is visionary and not. The bulk of that $613bn space economy is unglamorous and already woven into daily life. Roughly speaking, it divides into the "backbone" — the satellites, launch, ground systems and components that make space work — and the far larger "reach" layer of applications that depend on space without looking like space: navigation and timing that underpins payments and logistics, Earth-observation data that prices crop insurance and tracks deforestation, and the connectivity that is rapidly extending broadband to the half of humanity still poorly served. The WEF/McKinsey work projects that by 2035 these reach applications will account for over a trillion dollars of value, embedded in supply chains, agriculture, defence, retail and digital communications. Most of that value will accrue to companies a diversified owner already holds.

What has changed in the past five years is that the "backbone" itself has become institutional. The decisive signal is not a single launch but the entry of patient, professional capital. Specialist managers such as Seraphim Space have built venture and listed vehicles dedicated to the sector; Seraphim's leadership has gone so far as to describe space technology as crossing a threshold into a "permanent institutional allocation," and its funds now count satellite operators, an electronics manufacturer and government-linked investors among their limited partners. Large asset managers have begun to lead later-stage rounds in space-data companies. Infrastructure funds — the vehicles that hold airports, toll roads and fibre — are, by the accounts of those raising capital from them, examining space infrastructure with the same lens they bring to terrestrial assets: long-lived, capital-intensive, contracted-revenue systems. Sovereign demand, much of it from Gulf and Asian states building domestic space capability as industrial policy, is reshaping the customer base as well as the investor base.

This matters because it tells a universal owner where the adjacent opportunity sits today. One does not need a thesis on Mars to recognise that satellite connectivity, Earth observation and position-navigation-timing are becoming critical infrastructure with the contracted, inflation-linked, long-duration cash-flow profile that pensions and sovereign funds prize. The investable near-term space economy looks less like a moonshot and more like the early build-out of a utility: towers and fibre, but in orbit. That framing — space as infrastructure first, frontier second — is the single most useful adjustment an allocator can make. It converts an intimidating subject into a familiar one, and it locates the prudent entry point well below the speculative frontier that dominates the headlines.


III. The cost curve that changes everything

Every frontier thesis in this report — power, the Moon, minerals, Mars — depends on one number: the cost of moving a kilogram from the surface of the Earth to orbit. For most of the space age that number was effectively a wall. In the Space Shuttle era it cost something on the order of tens of thousands of dollars to lift a single kilogram to low Earth orbit; figures around $54,000/kg are commonly cited. At that price almost nothing closes economically, which is why for decades space was the province of governments and a handful of strategic communications businesses.

Reusability broke the wall. By recovering and re-flying the first stage of its rockets, SpaceX drove the marginal cost of a Falcon 9 launch down dramatically; credible estimates now put the cost to LEO in the range of roughly $1,400–$2,700 per kilogram, a reduction of around 95% from the Shuttle and something close to a twenty-to-thirty-fold improvement. The next vehicle in the sequence, the fully reusable Starship, is designed to attack the number again. The company's stated ambitions — and they are ambitions, not achievements — point toward roughly $100–$150 per kilogram over time, with a near-term target of well under a few hundred dollars. Independent analysts are sceptical of the most aggressive figures and of the timeline, and they are right to be: the history of launch is littered with cost projections that slipped by a decade. But even the conservative case is transformative. A move from $54,000 to $2,000 already happened; a move from $2,000 to a few hundred is plausible within the horizon of a pension liability.

The right way for a long-horizon owner to think about this is as a learning curve, not a single breakthrough. The relevant analogy is not the Apollo programme but the semiconductor and solar-module cost declines — the steady, compounding, capacity-driven reductions that turned exotic goods into commodities and, in doing so, created industries that did not previously exist. When the cost of access falls by an order of magnitude, activities that were absurd become merely expensive, and activities that were merely expensive become routine. Large constellations of satellites, on-orbit servicing, in-space manufacturing, and the assembly of structures too large to launch in one piece all move from the "impossible" column to the "engineering" column. The cost curve is the master variable because it is the thing that decides whether every other thesis in this report is a fantasy or a schedule. A universal owner's single most important monitoring task in this domain is therefore not to track any one company but to track the trajectory of cost-per-kilogram, because that line is the leading indicator for everything downstream.


IV. Energy from the sky

The most consequential off-world thesis for a universal owner is also, intriguingly, the one most directly tied to a problem the owner already worries about: energy. Space-based solar power is a deceptively simple idea with a century of conceptual history. A satellite in a high orbit collects sunlight almost continuously — no night, no clouds, no atmosphere to attenuate the beam — converts it to microwaves or laser light, and transmits it to a receiving antenna on the ground, which feeds it into the grid as baseload electricity. The appeal to a long-horizon allocator is obvious: it is, in principle, firm, weather-independent, geographically flexible clean power, the missing piece in a decarbonisation story otherwise dominated by intermittent sources.

For most of its history the idea failed on a single fact: it was wildly uneconomic to loft thousands of tonnes of solar array into orbit. The cost curve described above is what has revived it. With launch costs collapsing and key technologies demonstrated, the question has shifted, in the words of analysts surveying the field, from one of fundamental physics to one of industrial scaling. The demonstrations are real. Caltech's Space Solar Power Demonstrator reached orbit and, through its MAPLE experiment, transmitted detectable power wirelessly in space and steered the beam — a genuine first. Japan, a long-standing leader in the underlying research, has been preparing the OHISAMA demonstration to beam power from a small satellite. The European Space Agency stood up its SOLARIS initiative specifically to assess feasibility, economics and regulation and to mature the enabling technologies, with a decision point on a larger programme. China has announced intentions to build a kilometre-scale array later this decade. The World Economic Forum has begun to frame space-based solar as a serious candidate technology for the energy transition rather than a curiosity.

Sobriety is essential here, and the sceptics deserve a full hearing. Critics — including some within the engineering press — argue that the economics remain daunting even with cheaper launch, that the systems require enormous, unprecedented in-orbit assembly, that the end-to-end efficiency of converting sunlight to microwaves to grid electricity is low, and that terrestrial solar plus storage is improving so quickly that it may simply win the race on cost. These are strong arguments and they may prove decisive. The honest position is that space-based solar power is not yet demonstrated to be economic, and may never be. But it has three properties that should keep it on a two-hundred-year owner's radar regardless. First, it is firm power, which the grid of a decarbonised world will be desperate for. Second, it is one of the few clean-energy concepts whose ceiling scales with humanity's ambition rather than with the land and materials available on Earth — a point that matters if one is genuinely thinking in centuries. Third, it is dual-use industrial policy: the nations and companies that master in-orbit assembly and wireless power transmission acquire capabilities that spill across the entire space economy. For an owner whose returns track the energy system and the technological frontier at once, space-based solar is not a position to take today; it is a technology to understand deeply and watch closely, because if it works, it reprices both energy and space simultaneously.


V. The Moon as industrial base

If energy is the thesis that connects space to the owner's existing worries, the Moon is the thesis that connects the frontier to a near-term, government-funded supply chain. The strategic insight that has reorganised lunar thinking over the past decade is the discovery and confirmation of substantial water ice, concentrated in permanently shadowed craters near the lunar poles. Water is not interesting because astronauts need to drink; it is interesting because, split into hydrogen and oxygen, it is rocket propellant. Propellant manufactured on the Moon, where the gravity well is a fraction of Earth's, changes the entire economics of operating beyond low Earth orbit. It is the difference between hauling every gram of fuel up from Earth and refuelling at a station already in space. This is the logic of "in-situ resource utilization" (ISRU): use what is already there rather than carry it.

The institutional vehicle turning this from theory into schedule is, notably, a public-private partnership a universal owner would find familiar. NASA's Commercial Lunar Payload Services programme — an initiative of roughly $2.6 billion — contracts private companies to deliver science and prospecting payloads to the lunar surface, deliberately seeding a commercial transportation market rather than building everything in-house. A wave of robotic missions has been targeting the south polar region to scout resources and test ISRU concepts in practice, including drills and instruments to measure the volatile content of the soil. Some ventures are reaching further still: prospectors aimed at mapping Helium-3, a light isotope rare on Earth and of speculative long-term interest for certain fusion concepts, have been manifested on commercial landers. The realistic near-term prize is not Helium-3, which remains highly speculative and dependent on fusion technology that does not yet exist commercially; it is the more prosaic and more achievable build-out of lunar propellant, power and landing infrastructure that would make everything beyond Earth cheaper to reach.

For a long-horizon owner the lunar story carries two lessons. The first is that the cislunar economy — the zone of activity between Earth and the Moon — is being bootstrapped now, with government anchor demand de-risking the earliest commercial steps in exactly the way early infrastructure has always been financed. That is a pattern allocators understand and, eventually, can participate in. The second is a caution: lunar resource extraction is hard, slow, failure-prone and a decade or more from anything resembling commercial return, and several of the early missions have failed outright or partially. The Moon rewards patience and punishes the impatient capital that has lately been drawn to it by narrative. The owner's posture should be to treat lunar industry as a genuine multi-decade infrastructure build whose first investable layer is transportation and services, not exotic mining — and to expect the timeline to slip.


VI. Mars and the very long horizon

Mars is where the report must be most disciplined, because it is where enthusiasm most easily outruns evidence. The vision — a permanent, eventually self-sustaining human settlement on another planet, a "second address" for the species — is the most emotionally powerful idea in the off-world economy and the least amenable to a discounted-cash-flow model. There is, today and for the foreseeable future, no investable Mars business in any prudent sense. The honest framing for an allocator is that Mars settlement is a multi-decade-to-century proposition with profound uncertainty attached to every step, and that anyone offering a fund "exposure to Mars" is selling a story.

And yet a two-hundred-year owner cannot simply file Mars under fantasy, for two reasons. The first is that the capability build-out aimed at Mars produces enormous nearer-term spillovers regardless of whether anyone reaches it on schedule. The very large, fully reusable launch systems being developed with Mars as their stated purpose are the same systems that would slash the cost of everything in Earth orbit and cislunar space; the life-support, power, robotics, and resource-processing technologies developed for Mars are dual-use across the entire frontier and, frequently, back on Earth. An owner does not have to believe in a Martian city by 2070 to benefit from the industrial base that the attempt creates. The second reason is the one most aligned with the universal owner's actual mandate: civilizational resilience. An institution explicitly tasked with carrying value across generations has, at least intellectually, a stake in the survival and expansion of the civilization whose economy it tracks. The argument for settlement as insurance against planetary-scale catastrophe is contested and uncomfortable, but it is not absurd, and it is precisely the kind of long-tail, civilization-level consideration a genuinely long-horizon steward is supposed to be able to hold in mind without panicking or dismissing it.

The relief-of-pressure framing deserves careful handling, because it is easy to state badly. The serious version is not that humanity will decant its population to Mars to solve crowding on Earth — the physics and economics make that impossible at any relevant scale for a very long time. The serious version is subtler: that moving certain activities off Earth — energy generation, heavy or polluting industry, resource extraction — could, over a century, reduce the environmental load that the terrestrial economy imposes on a finite planet, while expanding the total resource base available to humanity beyond what one world contains. Mars settlement is the most distant expression of that idea; orbital industry and lunar and asteroid resources are its nearer cousins. For the owner, Mars is best understood not as an allocation but as the far horizon of a continuum that begins with very ordinary satellites and runs through orbital power and lunar propellant. It anchors the imagination and clarifies the direction of travel, even as it remains, financially, off the table.


VII. Minerals from the sky

The fourth thesis returns the discussion to hard economics, and to another problem the universal owner already carries: the rising environmental, social and geopolitical cost of extracting critical minerals on Earth. Asteroid mining proposes that some near-Earth asteroids are, in effect, unmined metallic ore bodies floating in space — particularly rich, on some bodies, in the platinum-group metals essential to catalysis, electronics and clean-energy hardware. The pitch made by the field's most prominent venture is arresting: because a metallic asteroid can be almost entirely valuable material rather than overburden, the gross margin on extracted platinum-group metals could in theory be vastly higher than the thin margins of terrestrial mining. Such claims should be read as aspirational rather than demonstrated, but the underlying geology is real and the strategic logic — relieving Earth of some of the dirtiest, most contested mining while expanding supply of metals the energy transition depends on — is genuinely attractive to a system-level owner.

The state of play is early and humbling. The leading platinum-focused venture launched a deep-space scouting mission in early 2025 — a 105-kilogram spacecraft built in under a year for a few million dollars, an extraordinary demonstration of how cheap the cost curve has made experimentation — and that mission ran into communications problems, a reminder that deep space remains unforgiving. A follow-on mission intends to attempt the first private landing on a metallic asteroid to measure its composition directly. This is genuine pioneering work, and it is also pre-revenue, technically unproven at the scale that would matter, and decades from returning a single gram of metal to market. There is, moreover, a deep economic objection that any allocator should hold front of mind: if asteroid mining ever did succeed at scale, the very abundance it unlocked could collapse the price of the metals it returned, undermining the business case that justified the investment. The history of resource booms suggests the first movers often subsidise the eventual winners.

For the universal owner the asteroid thesis is therefore a study in asymmetry and patience. The probability that any specific venture succeeds commercially within an investment horizon is low; the consequence if the field as a whole eventually works is large, both as opportunity and as a repricing risk to terrestrial mining assets the fund already owns. This is the recurring structure of the entire off-world economy: small, uncertain, venture-scale opportunities to participate directly, sitting atop large, slow-moving implications for assets the fund holds anyway. The sophisticated response is not to chase the venture but to understand the implication — to recognise that a fund heavily exposed to terrestrial mining, or to the metals supply chain, is also, quietly, exposed to the very long-tail possibility that the supply chain moves off-planet.


VIII. The risks a universal owner actually carries

A report that only enumerated opportunities would be marketing, not research. The off-world economy carries risks that are, for a universal owner, more immediately relevant than most of the upside — because they threaten infrastructure the fund already depends on and assets it already holds. Four deserve board-level attention.

The first and most concrete is orbital debris. Low Earth orbit is filling with both active satellites and the wreckage of past missions. By 2025 the active satellite population had climbed past 9,000 and toward 12,000, the majority in a single commercial constellation, while the European Space Agency's environment reporting put the number of debris fragments larger than a centimetre above 1.2 million, with tens of thousands large enough to destroy a satellite on impact. The systemic fear is the "Kessler syndrome": a cascade in which collisions generate debris that causes further collisions, potentially rendering valuable orbits unusable for generations. The warning signs are already visible in the sheer frequency of collision-avoidance manoeuvres now required — by some accounts, hundreds of thousands in a single half-year for one operator alone. For a universal owner this is not an abstraction. The reach economy that sits inside the fund's portfolio — connectivity, navigation, Earth observation, and the terrestrial industries that depend on them — rests on the continued usability of orbit. Debris is a textbook systemic, economy-wide externality: no single actor is incentivised to fix it, every actor contributes to it, and a bad outcome impairs many holdings at once. It is precisely the kind of risk universal-ownership theory says the largest, most diversified funds should care about and, where they can, use their influence to mitigate.

The second risk is the legal vacuum. The foundational instrument of space law, the 1967 Outer Space Treaty, prohibits national appropriation of celestial bodies and frames their use as being for the benefit of all countries. It was written for a world of two superpowers and no commerce, and it is silent or ambiguous on the central question of the new era: who owns what is extracted. The United States and a growing list of partner nations have advanced, through national legislation and the Artemis Accords, the position that an entity may own the resources it extracts even if it cannot own the territory — an interpretation that supporters say is consistent with the treaty and that critics argue erodes its spirit of common benefit. Crucially, the Accords are political commitments without an enforcement mechanism, and a rival bloc of spacefaring nations has not signed them. The result is a property-rights regime that is unsettled, contested and geopolitically fractured at exactly the moment large capital would need legal certainty to commit. For an allocator, regulatory and legal ambiguity of this kind is not a footnote; it is a first-order reason that the frontier theses remain uninvestable in size, and a live geopolitical risk that could harden into outright contest over the most valuable lunar real estate.

The third risk is the hype cycle. Cheap access and a compelling narrative have drawn a wave of capital into space ventures, and the base rate for frontier-technology investing is unambiguous: most ventures fail, valuations overshoot, and a great deal of capital is destroyed before the durable winners emerge. A universal owner is structurally well placed to avoid the worst of this — its advantage is patience, not picking — but only if it resists the pressure to "have a space allocation" for narrative reasons and instead waits for the structure, the cash flows and the legal regime to mature. The fourth risk is stewardship and ethics: the planetary-protection questions around contaminating other worlds, the equity questions embedded in a treaty that promised the benefits of space to all of humanity, and the governance questions that arise when a handful of private actors and nations acquire decisive capability beyond Earth. These are not soft concerns for a universal owner; they are exactly the system-level externalities that such an owner is, in theory, both exposed to and positioned to influence. An institution that intends to be a serious participant in the off-world economy should expect to be asked, by its beneficiaries and by the public, what kind of off-world economy its capital is helping to build.


IX. Forecast: three scenarios to 2050 and beyond

Forecasting a frontier is an exercise in humility, and the scenarios below are framed as coherent possibilities rather than predictions. They are most useful as a way of pressure-testing what a long-horizon owner should watch and how it should be positioned.

Base case — "Space becomes infrastructure" (most likely, 15–25 years). Launch costs continue to fall along the reusability learning curve without necessarily hitting the most aggressive targets. The reach economy — connectivity, observation, navigation — matures into critical, contracted, utility-like infrastructure that is unambiguously institutional and sits comfortably in infrastructure and listed-equity portfolios. The Moon develops a modest, government-anchored commercial transport-and-services economy. Space-based solar power, asteroid mining and Mars settlement remain in demonstration or early-development phases, advancing but not yet commercial. Orbital debris is managed adequately through a patchwork of national rules and operator practices but remains a chronic, unresolved systemic risk. In this world the universal owner's space exposure is real, growing, and largely accessed through ordinary infrastructure and equity holdings rather than exotic vehicles — and the fund that understood this early is better diversified and better informed than the one that did not.

Upside case — "The cost wall truly breaks" (plausible, lower probability). Fully reusable heavy launch achieves something close to its cost ambitions, and access to orbit becomes genuinely cheap. In-orbit assembly and manufacturing mature; at least one frontier thesis — most plausibly space-based solar power or lunar propellant — crosses into early commercial viability. A workable, if imperfect, international framework for space resources emerges, giving capital enough certainty to commit at scale. The space economy overshoots its $1.8tn projection and begins to look like a genuine new industrial layer of the world economy. In this world the early, thoughtful institutional participants — and the patient capital that helped finance the infrastructure — capture a meaningful new return stream, and the direction of several terrestrial industries (energy, mining, telecommunications) is permanently altered.

Downside case — "The orbits close" (low probability, high impact). A major debris cascade, a collision-driven Kessler event, or escalating geopolitical conflict in orbit degrades the usability of key orbits and the reliability of the space-based services the global economy now assumes. Insurance becomes unobtainable for some orbital regimes; the reach economy embedded across the universal owner's portfolio is impaired simultaneously; the legal vacuum hardens into open contest over lunar resources. The frontier theses are set back by a decade or more, and a great deal of frontier capital is destroyed. This is the scenario that should most concern a universal owner, precisely because its losses fall not on a small speculative allocation but across a wide swath of an already-held portfolio — and because it is the scenario the owner's scale and influence are best suited to help prevent.

The asymmetry across these scenarios is the strategic point. The direct upside of the frontier is venture-scale and uncertain; the systemic downside is portfolio-wide and underpriced. A long-horizon owner that thinks clearly about space will often conclude that its most valuable action is not to chase the upside but to understand and help mitigate the downside.


X. From the allocator's seat

What, concretely, should an investment committee that takes its two-hundred-year mandate seriously actually do? The answer is not a target allocation to "space." It is a posture, built in layers from the prudent to the speculative.

The first and largest layer is simply to see the exposure you already have. A globally diversified fund already owns the incumbent winners of the near-term space economy — the aerospace and defence primes, the semiconductor and component makers, the satellite operators and telecommunications networks, the energy and industrial firms that will build and consume orbital infrastructure. The first task is analytical, not transactional: map where in the existing portfolio space exposure is concentrated, understand the contracted-revenue, infrastructure-like quality of the best of it, and identify the systemic risks — debris, regulatory contest — that could impair many of those holdings at once. This costs nothing and is pure improvement in understanding.

The second layer is space as infrastructure. For funds with infrastructure mandates, the most defensible direct participation is in the utility-like layer of the space economy — long-lived, capital-intensive, contracted assets in connectivity, observation and ground systems — underwritten with the same discipline applied to any infrastructure asset, and sized modestly. This is the entry point that fits an institutional risk appetite without requiring a bet on the frontier.

The third layer, for funds with the governance and risk budget for it, is a small, deliberately venture-shaped frontier sleeve — accessed through specialist managers rather than direct positions, sized as one would size any high-variance, long-duration venture exposure (small enough that total loss is tolerable), and held with genuine patience. The purpose of this sleeve is as much informational as financial: it buys a seat close to the frontier, a flow of intelligence, and the option to scale if and when a thesis matures. It should never be sized as though the frontier theses were probable, and it should be governed as a learning expense as much as a return-seeking position.

Cutting across all three layers is the stewardship dimension, which for a universal owner is not optional. The same scale that makes debris and the legal vacuum portfolio-wide risks also gives the largest owners a voice — through engagement, through the standards they demand of the companies they own, through the policy conversations they can join — in shaping whether the off-world economy is built sustainably and governed sensibly. A universal owner's most distinctive contribution to the space economy may turn out to be not its capital but its insistence, as a permanent and diversified shareholder, that orbit be kept usable and the frontier be developed responsibly. That is the universal-ownership thesis applied to a new domain: when you own a slice of everything, your job is not only to allocate but to steward the system your returns depend on.


Questions for investment committees

  • Where in our existing portfolio is space exposure concentrated today — across aerospace, semiconductors, telecommunications, energy and industrials — and do we understand it as exposure to a single secular transition?
  • Have we distinguished, explicitly, between the investable near-term space economy (infrastructure-like connectivity, observation, navigation) and the uninvestable frontier (orbital power, lunar and asteroid resources, Mars)? Are we at risk of buying the second while believing we are buying the first?
  • Do we treat orbital debris and the contested legal regime as systemic risks to assets we already hold, or only as reasons not to invest in something new?
  • If we were to take a frontier sleeve, is it sized as a tolerable-total-loss learning expense, accessed through specialists, and governed accordingly — or are we tempted to size it to a narrative?
  • What is our single most important monitoring metric in this domain, and have we agreed that it is the trajectory of launch cost-per-kilogram rather than any individual company's milestones?
  • As a large, permanent, diversified owner, what is our stewardship position on keeping orbit usable and on how space resources should be governed — and are we using our influence, or merely our capital allocation, to express it?
  • What would our beneficiaries and the public expect of us, over a fifty-year horizon, regarding the kind of off-world economy our capital helps to build?

Signals to watch

The trajectory of launch cost-per-kilogram, especially evidence on whether fully reusable heavy-lift achieves and sustains an order-of-magnitude reduction; the outcome of space-based solar power demonstrations and any credible levelised-cost estimates; the success or failure rate of lunar landers and the first working in-situ resource utilization demonstrations; the progress and economics of the first asteroid prospecting and landing missions; the maturation (or fracture) of an international legal framework for space resources, including which nations align with which bloc; the rate of debris-driven collision-avoidance manoeuvres and any actual cascade events; insurance availability and pricing for orbital regimes; and the continued entry — or retreat — of infrastructure funds, sovereign funds and large asset managers as durable institutional capital in the sector.

Bottom line

The off-world economy asks a universal owner the question its entire structure was built to answer: how should capital that genuinely thinks in generations relate to a transition that is real, large and slow? The disciplined answer is not to romanticise space and not to dismiss it. The near-term reality is mundane and already institutional — space is becoming infrastructure, and a diversified fund owns it whether it has noticed or not. The frontier theses — power beamed from orbit, propellant and metals mined off-world, a human presence on the Moon and eventually Mars — are genuine, civilization-scale possibilities that remain unpriced, unproven and wrapped in systemic risks that fall on the portfolio the fund already holds. For the two-hundred-year owner, the work is to see the exposure it already has, to participate where the cash flows and the law are mature, to keep a small and humble window on the frontier, and above all to steward the system — because when you own a slice of everything, the usability of orbit and the governance of the frontier are not someone else's problem.
