# Commercial space station market has stratified into three tiers by development phase with manufacturing-ready programs holding structural advantage over design-phase competitors

The commercial space station market has developed a three-tier structure based on development phase maturity as of March 2026. Tier 1 (manufacturing): Axiom Space passed Manufacturing Readiness Review in 2021 and "already finished manufacturing hardware for station modules scheduled to launch in 2027"; Vast completed Haven-1 module and is in testing ahead of 2027 launch. Tier 2 (design-to-manufacturing transition): Starlab completed Commercial Critical Design Review in 2025 and is "transitioning to manufacturing and systems integration." Tier 3 (late design): Orbital Reef completed System Definition Review in June 2025, still in design maturity phase. This stratification matters because execution timing gaps compound: while Orbital Reef was celebrating SDR completion, Axiom had already moved to flight hardware production. The gap represents 2-3 milestone phases (roughly 18-36 months of development time). Turner's analysis emphasizes that "technical competence alone cannot overcome the reality that competitors are already manufacturing flight hardware while Orbital Reef remains in design maturity phases." The tier structure is reinforced by capital access patterns: Tier 1 programs have secured massive private capital ($2.55B for Axiom) or institutional financing ($40B facility for Starlab), while Tier 3 relies primarily on Phase 1 NASA funding ($172M for Orbital Reef). This creates path dependency where early execution advantages compound through better capital access, which enables faster progression through subsequent milestones.
