Contract data: USAspending.gov (federal prime contract obligations, award types A-D, by action date) and the Department of Defense daily contract announcements (awards of $7.5 million or more). Both are public-domain U.S. government data. Company matching uses legal names and parent/child recipient records and is deliberately conservative, so some subsidiaries may be missing. Obligations are not revenue. Not investment advice.
