OMNIA Partners

OMNIA Partners describes itself as the nation's largest cooperative purchasing organization. Its own company history dates the business to 2001 in Franklin, TN, with U.S. Communities added in 2018; the OMNIA Partners parent entity was formed in 2017. 500,000+ total members across public and private sectors (2025, company-reported); within that, 150,000+ public-sector member agencies plus 25,000+ member locations via the CHAMPS/WellLink partnership - agencies, locations, and members are distinct constructs, and no published arithmetic connects the agency and location figures to the 500,000+ member total. OMNIA publishes two volume figures under different constructs: approximately $35B in annual managed B2B spend (2025, company-reported) and $10B+ in annual member purchasing volume; no published arithmetic reconciles the two and the difference is not explained in the company's own materials. Spans public sector (state/local government, K-12, higher ed) and enterprise/private sector, with a growing healthcare-adjacent footprint following the October 2024 acquisition of non-healthcare members from Capstone and Yankee Alliance. Its September 2025 growth investment from Alphabet's CapitalG is a consequential signal in the commercial GPO market, funding a pivot toward AI-driven procurement. Note: OMNIA is generally positioned as a non-healthcare GPO, but its 2023 purchase of Premier's non-healthcare business, its 2024 non-healthcare membership pickups, and a 2022 Medline medical-supplies cooperative agreement complicate a strict 'avoids healthcare' characterization.

OMNIA Partners' own About page says the 2018 addition of U.S. Communities "solidifies OMNIA Partners as the largest, most experienced public-sector cooperative purchasing organization in the country" (omniapartners.com/about-us, read 2026-09-11) — the company's own characterisation, not an independent ranking. The platform combines the former National IPA and U.S. Communities books across public-sector and commercial verticals. Its principal commercial rival is CoreTrust, which competes on private-equity depth rather than volume. Dominates government, education, and non-profit purchasing, with growing healthcare-adjacent presence.
