Market spending and contractor rankings use public USAspending.gov awards when NAICS is present on warehouse rows, otherwise SAM.gov Award Notices in CaptureIQ’s shared catalog. Current opportunities use public SAM.gov and Grants.gov notices. Contractor names are awardees from those records only — not inferred competitors.
