The Department of the Navy stands out for award count, with 36,009 awards and 7.34 billion obligated, indicating a much more fragmented buying pattern than the other top agencies. CMS also ranks among the largest buyers at 4.34 billion, underscoring demand from civilian health IT programs.
Vendor concentration and leading contractors
Booz Allen Hamilton Inc. is the largest vendor in this PSC with 4.08 billion obligated across 1,209 awards, followed by Accenture Federal Services LLC at 3.21 billion and General Dynamics Information Technology, Inc. at 3.18 billion. Cerner Government Services, Inc. has 3.11 billion across only 212 awards, suggesting larger individual awards, while Leidos, Inc. combines 2.63 billion with 16,066 awards, indicating a broad distribution of tasking across many actions.
Annual contract trend over the analysis window
Annual obligations rose sharply from 7.12 billion in 2021 to 13.27 billion in 2022 and 16.13 billion in 2023, then reached 21.64 billion in 2024 and 21.65 billion in 2025. Award counts also increased each year, from 6,472 in 2021 to 32,842 in 2025, showing both higher spend and expanding transaction volume over the period. The near-flat year-over-year level between 2024 and 2025 suggests continued high demand rather than another major step-up.
