Investment Trends Summary

✓Launch consolidation — The market is converging around reusable vehicles. Companies without a reusability roadmap face existential risk. SpaceX dominance is driving competitors to innovate faster.

✓Defense spending acceleration — US Space Force and SDA budgets are growing 15-20% annually. Proliferated LEO is the new architecture paradigm, creating demand for mass-produced satellites.

✓EO data monetization — Earth observation is shifting from "selling images" to "selling insights." AI analytics companies command higher margins than raw imagery providers.

✓Commercial stations timeline — ISS retirement (late 2020s to early 2030s) creates urgency. NASA has committed $3.6B to ensure no gap in US human presence in LEO. Multiple contenders are in development.

✓Vertical integration trend — Leading companies (SpaceX, Rocket Lab) are integrating across launch, satellite manufacturing, and services. This trend is likely to continue as margins compress in commoditized segments.
