Updated October 6, 2026. Read from USAspending.gov. Public U.S. federal spending data (U.S. Department of the Treasury). Obligations are the contract actions dated in fiscal years 2024 to 2027 of the USAspending.gov award archive of 2026-10-06; a contract's total value is its current value as USAspending reports it, including earlier years. Recipients are matched on their SAM.gov UEI, never on the name, and are shown as the government prints them. Sole proprietorships and opted-out entities count in the totals and are not named.
