The Space Sector Is Financeable. Lenders Cannot Prove It Yet.

The space sector has a credit problem that the investment data makes visible.

Private investment peaked at $18 billion in 2021. By 2024, it had fallen to $5.9 billion. In 2025, it rebounded to $12.4 billion, with the largest rounds flowing to operators serving defense and sovereign customers. Early-stage and speculative ventures attracted a diminishing share of that capital.

The rebound reveals the underlying problem. Capital returned selectively, flowing to operators with government revenue visibility and exiting everything else. Without tools to distinguish creditworthy operators from weak ones, the market defaults to proximity to sovereign revenue as its only available signal.

Over the same period, orbital populations expanded and launch cadence accelerated. By the first half of 2025, a launch was occurring every 28 hours, six hours faster than the full-year record set in 2024. The underlying asset class was not deteriorating. Capital was returning to the names it already knew.

The Collateral Problem and the Credit Problem Are Not the Same

Most commentary on space finance focuses on collateral. The problem is real. Once deployed, a satellite cannot be physically recovered, repaired, or repossessed under normal circumstances. It is a single-use, non-recoverable asset. That limits its utility as primary security in a conventional financing structure.

But the collateral problem is a symptom of something deeper.

There is no standardized probability of default framework for orbital operators. Insurance underwriting in the sector relies on engineering-based loss models. Lenders who attempt space asset financing typically reach for infrastructure heuristics, specifically frameworks built for toll roads, pipelines, and port assets, and apply them to orbital operators. Those frameworks were not designed for the risk factors that actually govern orbital credit: collision probability, orbital decay rates, spectrum licensing continuity, operator revenue concentration, and sovereign contract dependency.

That last factor is underweighted in most lender analysis. Between 2020 and 2024, governments worldwide financed $252 billion in space infrastructure. Private entities contributed $48 billion, two-thirds of it in telecommunications. The structural dependence on government revenue means that a significant portion of operator cash flow is subject to sovereign budget cycles, procurement policy shifts, and geopolitical reallocation. A lender applying a commercial infrastructure DSCR model to an operator whose primary offtake counterparty is a government ministry is not conducting credit analysis. It is conducting an approximation of credit analysis.

What Mispriced Risk Looks Like in Practice

When a lender cannot differentiate credit risk across an asset class, the pricing mechanism breaks in a predictable way.

Cost of capital stays elevated across the board. An operator with contracted multi-year revenue, diversified sovereign and enterprise customers, and a technically stable orbital slot pays the same risk premium as an operator with a single-customer dependency and a deteriorating spectrum position. The spread does not reflect the underlying difference in default probability. It reflects the absence of a framework capable of measuring that difference.

Failures then compound the problem. Virgin Orbit ceased operations. Momentus and Astra delivered results that raised questions about NewSpace profitability. When those failures occur in a market with no credit differentiation framework, the entire sector reprices. Investors cannot distinguish the failed business model from the viable one, so they apply the uncertainty to both. The solvent operators bear the financing cost of the insolvent ones. That cross-subsidization persists until differentiation tools exist to break it.

Debt financing as a share of total space investment rose from 0.4% in 2019 to 7% in 2023, a 53% year-on-year increase over that period. The demand for debt capital is building. The analytical infrastructure to price it is not.

The Gap Is Analytical, Not Regulatory

Orbital assets have the structural characteristics of financeable infrastructure. They generate contracted revenue. They serve sovereign and enterprise customers under multi-year agreements. The risk factors are identifiable in principle, even if not yet formalized.

The legal community has recognised the problem. The Cape Town Convention's Space Assets Protocol, concluded in 2012, was designed to extend asset-based financing frameworks to satellites, creating internationally enforceable security interests for lenders. Over a decade later, it has zero ratifications and is not in force. The satellite industry itself opposed it, arguing that the existing financing models were sufficient. That position has not aged well.

The deficit is not legal. Lenders do not lack the contractual tools to structure space transactions. What they lack is the credit intelligence to decide whether to structure them at all. Asset-based financing in aviation rests on decades of default data, standardized collateral valuation methodologies, and credit frameworks that allow lenders to price risk rather than avoid it. The satellite sector has none of that.

Those frameworks have a specific form for orbital assets. Probability of default at one-, three-, and five-year horizons. Operator-level scoring calibrated to orbital regime, mission type, revenue structure, and sovereign dependency. Risk distributions that allow a lender to set pricing and covenants rather than pass on the transaction entirely.

Until those outputs exist at an institutional standard, lenders will continue to use approximations. Approximations produce mispriced capital. Mispriced capital penalises the operators most likely to build durable orbital infrastructure and subsidises uncertainty across the rest.

The global space economy reached $626 billion in 2025, on a trajectory toward $1 trillion by 2032. The investment rebound confirms that institutional appetite for the asset class exists. It also confirms that appetite is currently conditional on sovereign anchors rather than credit analysis. That conditionality is the market telling you exactly where the gap is.
