Data coverage and methodology
Sources: SAM.gov registration, USAspending awards and transactions, and linked supporting records. Prime contract obligations, IDV ceilings and assistance amounts are kept separate. Missing records are not zero activity. Company claims are labeled separately. Recompete signals are rule-based scores out of 100. Positioning windows are AcornBids estimates.
No official subaward rows are loaded, so Acorn does not claim known teaming relationships.
