The 14-Layer Stack (Bottom to Top)
Each card represents one layer of the space economy. Layers are ordered from foundational infrastructure at the bottom to frontier applications at the top. The width of each bar is proportional to market size.
Highest Growth Layers by CAGR
Emerging and frontier segments of the space economy are growing at multiples of the overall industry rate. These layers represent nascent markets with transformative potential but currently account for a small share of total space revenue.

Space Economy Market Projections
The space economy has more than doubled since 2010, driven by commercial satellite services, reusable launch vehicles, and government procurement of commercial space capabilities. The trajectory from $626B (2026) to $1T+ (2034) implies 6-8% CAGR at the aggregate level, with frontier segments (in-space manufacturing, lunar, space computing) growing at 20-40% annually. Satellite communications remains the largest single segment, accounting for roughly $45 billion of the commercial total. The defense segment ($30B) reflects growing military space budgets across the US, China, and Europe.
The space economy stack reveals two distinct dynamics: mature infrastructure layers (launch, satellite manufacturing, communications) that generate the bulk of revenue, and high-growth frontier layers (in-space manufacturing, lunar, space computing) that are growing at 20-40% CAGR but from small bases. The critical enabler is launch cost reduction -- SpaceX has driven cost-per-kg down by over 90%, and Starship could reduce it by another order of magnitude. Every layer above launch benefits from cheaper access to orbit. The space economy crossed $500B in 2023 and is on trajectory to reach $1T by 2034, making it one of the most predictable growth markets in deep tech.
