Data & Methodology

Federal contract and award data sourced from government procurement systems — including FPDS-NG, SAM.gov, and related federal data repositories. PrimeRFP SCOUT ingests, normalizes, and continuously updates records as agencies publish them. Reporting timelines vary by agency; some components (particularly DoD) carry a 60–90 day lag relative to award execution.

Dataset coverage — ≥ $100K floor

All intelligence on this page and within SCOUT is filtered to contracts with a cumulative current value of $100K or more. This threshold covers 98%+ of all federal contract dollars while filtering out micro-purchases and administrative actions — over 560,000 active contract awards and 2.5 million unique awardees, including small business set-asides, task orders, and mid-market opportunities.

Award identification: Each record is keyed by federal Award ID (PIID). Task orders recorded as independent awards appear as separate rows. IDIQs and their task orders are tracked distinctly.

Why SCOUT dollar figures differ from published annual totals: Per-agency dollar figures on SCOUT intelligence pages aggregate all USASpending transaction records — including base contract awards, task orders, delivery orders, and modifications to existing contracts. Annual federal contract obligation figures cited in industry reports (e.g., FY2025: $833.8B per Bloomberg Government) count only new prime award actions in the fiscal year, excluding mods. An IDIQ vehicle (like OASIS+) carries no obligation at award — only task orders issued against it are counted. SCOUT's transaction-level aggregates are larger because they capture the full activity picture across a contract's lifecycle, making them useful for competitive analysis and pipeline sizing rather than year-over-year spending comparison.
