Who buys Product and Service Code B599 (Special Studies/Analysis – Other), who wins it, what's open now and which contracts expire next — from FY2026 USAspending awards and live SAM.gov solicitations.
Contract data as of Oct 18, 2026 (USAspending) · recent coverage verified weekly
| Quarter | Awards | Obligated | Change |
|---|---|---|---|
| Q1 FY2026 | 45 | $58.7M | — |
| Q2 FY2026 | 46 | $38.6M | -34% |
| Q3 FY2026 | 52 | $18.3M | -53% |
| Q4 FY2026 · partial | 110 | $41.9M | +130% |
Federal fiscal quarters (Q1 = Oct–Dec). Awards are counted in the quarter they start; obligations are the award's obligated amount. The Department of Defense publishes contract awards to USAspending with a 90-day delay, so Q4 FY2026 is still missing most DoD awards (DoD is 32% of this code's dollars) — treat that quarter as incomplete, not as a spending decline.
