SpaceNexus Supply-Chain Concentration Report
Who supplies whom in the space industry, from official records only: federal subawards reported on USAspending.gov and statements in SEC annual reports, each linked.
Live view: recomputed from current data, not the published edition. The published edition was frozen on 2026-10-08 and changes only through a dated correction.
: The coverage statement on this edition was wrong about how the map was made. It said the relationships were curated by hand from public sources and reviewed against sources, that criticality and risk were ratings made by hand, and that nothing on the page was model-generated. The supply-chain map and the bill-of-materials register were written into our code by an AI assistant in February 2026 from its general knowledge, not from cited sources, and were last reviewed for errors (an AI-assisted review) on 2026-03-25; no relationship, rating or shortage carries a source. The figures are unchanged. The coverage statement now says how the map was made, and the figures describe that sample, not sourced research.Replaced: Mapped relationships 30; Top supplier country United States; Top three countries 66.7%; Single-source dependencies 10

•Editions before the third quarter of 2026 were computed over a supplier map and a bill-of-materials register, both written into our code by an AI assistant in February 2026 from its general knowledge, not from cited sources; no entry carried a source.
•Those editions were withdrawn on 2026-10-10: their figures, tables and files are removed, and each carries a dated note. SpaceNexus holds no record of the sourced supply chain as it stood when they were published, so nothing replaces them. The sourced supply chain is on the supply-chain page.

Every figure here is arithmetic over our own rows (counts, sums, deltas and rankings), and the page and its export are built by the same code, so they cannot disagree. How this edition is computed
