Federal contracts awarded through full and open competition after exclusion of sources represent a substantial market segment, with total obligations exceeding $1.5 trillion across more than 11 million awards. This category accounts for approximately 9 percent of federal contracting dollars, indicating a significant but not dominant share of overall procurement activity. Award sizes average around $134,000, reflecting a mix of both high-volume, lower-value transactions and larger individual contracts. The market shows strong concentration within defense-related agencies, with the Department of the Army, Navy, and Air Force collectively responsible for over $800 billion in obligations, highlighting the strategic importance of this competition type in military procurement. Vendor concentration is notable as well, with a handful of companies such as Atlantic Diving Supply and Huntington Ingalls receiving multi-billion dollar awards, suggesting a limited pool of suppliers capable of meeting the specialized requirements inherent to these contracts. Historical trends indicate that this contracting method has grown substantially since the 1980s, though early data show sporadic activity before stabilizing into a consistent pattern of large-scale spending. For analysts, contractors, and procurement researchers, this page underscores the importance of monitoring agency-specific procurement behaviors and vendor performance within this competition framework to identify opportunities and assess market dynamics. The data provide a foundation for evaluating how exclusion of sources influences competition intensity and vendor participation in federal contracting.
