Ranked by contract-coded (NAICS) obligations, so entitlement grants routed through state agencies do not crowd out the primes. This is a description of the money, computed by us from USASpending records, never a judgment about any contractor. Each row opens that contractor’s page: its funding agencies, where the work lands, and any PAC on record.

🔎
Why the labels? The graph is only worth anything if the links are trusted. Facts taken straight from a federal filing are ✓ from source; figures we calculate are ≈ computed; links we infer (corporate parents, districts, competitors, connections between records) are ≈ inferred, worded carefully, never asserted as fact and never a claim that one thing caused another.
