## What the Space Score is

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.

## Methodology

- The Space Score is a 0–1000 composite computed daily from SpaceNexus data across five pillars: Scale (30%), Government space demand (20%), Capital access (15%), Momentum (15%) and Flight record (20%). Every metric, formula, window and source is published on the methodology page, with a per-company breakdown.
- Each metric is a percentile rank among the tracked companies that have a value for it, so the score measures relative standing on evidence we hold, not management quality, and not a forecast.
- A pillar that does not fit a business (a flight record for a company that does not launch) is dropped and the weights re-normalised. A pillar that applies but has no data counts at the midpoint, so missing data neither lifts nor sinks a company. Companies with too little data are scored but not ranked, and every row carries a confidence label.
- This table ranks the top 25 ranked companies by total score. Ties break on data coverage, then company name (A–Z), so the order is reproducible.
- Editions are quarterly and dated by when the inputs were measured. The current quarter updates daily and freezes when the quarter ends. Rank movement is shown only against a previous edition computed under the same methodology version; the hand-set table retired on 2026-09-23 is never compared against.
- This is not investment advice. The Space Score is a descriptive composite, not a forecast or a recommendation.
- Methodology version 3.
