Source: USAspending.gov prime award data (FPDS), DoD and DHS contracts, orders and IDVs with any action since Oct 1, 2023. Obligated FY2024+ sums the obligations on those actions; total obligated is the award's lifetime figure. DoD contract actions publish on USAspending about 90 days after signing (DFARS PGI 204.6), so the latest DoD actions here trail the calendar by about 3 months. Data as of Oct 24, 2026.
