Federal contracts awarded through full and open competition represent a substantial portion of federal procurement, accounting for approximately $8.4 trillion in obligations and half of all contract spending. The market is characterized by a high volume of awards, with nearly 59 million contracts issued, averaging around $143,000 per award. Spending is heavily concentrated among a few key agencies, notably the Department of the Army, Navy, and Air Force, which together account for a significant share of the total obligated funds. The Defense Logistics Agency also plays a major role, particularly in terms of award count, indicating a broad distribution of smaller contracts alongside large-dollar awards. Vendor concentration is evident with major contractors like Lockheed Martin and McKesson Corporation receiving tens of billions each, though the presence of vendors with fewer but high-value awards suggests varied procurement strategies. Historical trends show a steady increase in obligations and award counts since the late 1970s, reflecting the growing scale and complexity of federal acquisitions under full and open competition. For analysts, contractors, and procurement researchers, this data underscores the importance of understanding agency-specific procurement patterns and vendor dynamics to navigate competitive federal contracting effectively. The scale and concentration patterns revealed here provide a foundational perspective for assessing market opportunities and competitive positioning within the federal procurement landscape.
