Each row is one action: a new award, or a modification that added money to an existing award. The amount is what that action obligated, not the award's total value, so a modification of a large contract is not a new contract of that size.
The week's actions fall in FY2026, which ended September 30 and was still posting when this was published, so its figures are not final.
Amounts are obligations recorded in USAspending with an action date from September 28 to October 4, 2026: a new award, or a modification that added money to an existing one. Awards can be modified later, so these figures can change in USAspending. DoD contract data posts to USAspending about 90 days after award. Source: USAspending.gov, read 2026-10-05.
