What this does not show
- Win rates are approximated from award history. Bid-level data is not public, so no source can tell you how many bids a vendor lost.
- Forecasts are linear trend projections over 8 fiscal quarters. Appropriations can move them in either direction.
- USASpending has reporting lags of days to weeks. Every figure carries its vintage: data as of Oct 9, 2026.
- Recompete scans cover contracts awarded or modified in the trailing 12 months. Older untouched contracts are outside the scan.
- US federal contracts only in v1. State, local, and international procurement are not included.
