Contract data as of Oct 18, 2026 (USAspending) · recent coverage verified weekly
| Quarter | Awards | Obligated | Change |
|---|---|---|---|
| Q1 FY2026 | 629 | $77.2M | — |
| Q2 FY2026 | 445 | $26.2M | -66% |
| Q3 FY2026 | 393 | $32.0M | +22% |
| Q4 FY2026 · partial | 243 | $36.6M | +14% |
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 17% of this code's dollars) — treat that quarter as incomplete, not as a spending decline.
