Week in Space Data, every Friday.
Quarterly ranking · Q4 2026 (Oct–Dec)
The 25 highest-scoring ranked companies (105 ranked of 373 scored), on a 0–1000 composite computed from our own data across scale, government space demand, capital access, momentum and flight record. Inputs measured 2026-11-15. Every metric, weight and company breakdown is published.
New methodology: no movement shown
The previous edition was produced under a different Space Score methodology, so ranks are not comparable and no movement is shown against it.
| # | Company | Sector | Score The Space Score is a 0 to 1000 snapshot of a space company's size and activity, relative to the other companies we track. It combines size (headcount, market value and revenue, 30%), U.S. federal space contracts (20%), equity raised (15%), momentum (15%) and, for launch companies, orbital launches (20%), so it leans heavily on size. It is descriptive: not a forecast, a rating or investment advice. | Tier | Data | Movement |
|---|---|---|---|---|---|---|
| Rank 1 | SpaceX | launch | 870 | Leader | High · 100%9 of 9 inputs | No prior edition |
| Rank 2. With the pillars we have not measured for this company filled at the 10th and 90th percentiles of the companies we did measure, and every other company held at its published total, the rank is likely between 1 and 6. | China Aerospace Science and Technology Corporation | launch | 866 | Leader | Medium · 77%3 of 5 inputs | No prior edition |
| Rank 3 | Boeing | defense |
The Space Score ranks companies relative to each other on public data we hold. It describes; it does not rate, forecast or recommend. It is not a credit rating and not investment advice. Full disclaimer

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

Inputs measured 2026-11-15 (UTC). Methodology version 8. The Data column is the confidence label, the share of the company’s applicable pillar weight backed by data, and how many of the inputs that apply to the company we measured. A rank shown as =8 is shared by companies with the same total.
A line such as “likely between 9 and 15” under a rank is where the company likely ranks given the pillars we have not measured for it: each such pillar filled at the 10th, then the 90th, percentile of the companies we did measure, with every other company held at its published total. No range means every applicable pillar is measured or the gaps could not move the rank. It is shown for the current edition only and never changes a score or a rank. How the range is computed.
Every metric, formula, weight and source, and each company’s pillar values and missing inputs, are on the Space Score methodology page.
This is the quarterly SpaceNexus Space Score Top 25. Every edition is dated and permanently linkable, and every figure is computed from SpaceNexus data rather than written. The full release calendar shows where each franchise stands.
Next edition: Q1 2027, due 2027-01-15.

The complete row set, every column included, is available as CSV and JSON to SpaceNexus Research subscribers: export this edition (JSON, every table); for subscribers each table above also carries its own CSV download. The export is computed from exactly the rows behind the tables above, so the page and the file can never disagree.
The same credits are written into every CSV and JSON export of this data, so a downloaded file still names its sources.
