GovSentry Open Datasets
Free, openly-licensed (CC BY 4.0) datasets for US government-contracting research — built and maintained by GovSentry from 40,000+ federal awards and 100+ state & local portals. Free to use, including commercially, with attribution (see how to cite).
Federal Niche Winnability Index (287 NAICS)
We scored every federal NAICS niche with at least 10 tracked awards for winnability — how realistic it is to win work there, separately for a small business and a large business. Each niche carries a 0–100 Target Score, contractor concentration, set-aside dollar shares by category, typical bidder counts, active opportunities, and the 12-month recompete pipeline.
How the Target Score is computed
score = 0.5 × openness + 0.5 × edge
- openness = 100 − the top-3 contractors' dollar share (how un-concentrated the niche is).
- edge (small business) = the % of dollars set aside for small business — work that excludes large primes.
- edge (large business) = the full-and-open % — set-asides shrink the market they can bid, so more open work scores higher.
