Contract data as of Oct 18, 2026 (USAspending) · recent coverage verified weekly
| Quarter | Awards | Obligated | Change |
|---|---|---|---|
| Q1 FY2026 | 4 | $8.6M | — |
| Q2 FY2026 | 6 | $258.1M | +2913% |
| Q3 FY2026 | 6 | $7.6M | -97% |
| Q4 FY2026 · partial | 9 | $7.3M | -3% |
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 95% of this code's dollars) — treat that quarter as incomplete, not as a spending decline.
