| Quarter | Awards | Obligated | Change |
|---|---|---|---|
| Q1 FY2026 | 1,651 | $34.1M | — |
| Q2 FY2026 | 2,056 | $43.9M | +29% |

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 79% of this market's dollars) — treat that quarter as incomplete, not as a spending decline.
