About this data
Awards, recipients, amounts, dates and agencies come from the public USAspending.gov API (DATA Act spending data, US federal government information), read once a week. This page covers contracts awards dated 2026-10-01 to 2026-10-30, the 30 days up to the newest award USAspending holds for this kind; federal agencies report with delays, so recent weeks can be incomplete and amounts can change. Only organisation recipients are listed: recipients that USAspending masks or that may be individuals or sole proprietors are left out, and no addresses are shown. The amount is the award value on that record, not necessarily money paid out. A listing here says nothing about the quality or conduct of any organisation.
