About this data

Primes: SBA's Directory of Federal Government Prime Contractors with Subcontracting Plans (FY2023 and FY2024 editions, the latest SBA has published), built from FPDS-NG. The agency that entered each record owns the data; questions about a contract go to that agency. "Active" means the listed completion date is today or later. Contract value is the base and all options value. We group contracts by the prime's UEI. Open opportunities: SBA SubNet, checked Oct 18, 2026 and weekly.
