# Kaiser Permanente **Kaiser Permanente** is the largest integrated nonprofit health system in the United States — simultaneously an insurer, a hospital operator, and a set of physician groups under one roof. It is the closest thing the U.S. has to a closed, prepaid managed-care model, and a useful contrast to the for-profit and PE operators mapped in the [[Healthcare Industry Ecosystem]]. ## Scale Kaiser cleared about **$115.8 billion in operating revenue (2024)** and covered more than **13 million members** (including its Risant Health affiliate). It owns roughly **55 hospitals** and over 800 medical offices, concentrated in California and a handful of other regions. Despite its scale and tax-exempt status, its operating margins are thin compared with the for-profit insurers. ## Why It Matters Here Kaiser is the structural counterexample: by combining insurance and care delivery in a nonprofit ([[Nonprofit Hospital]]) frame, it internalizes incentives that the fragmented fee-for-service system splits across [[Managed Care]] insurers, hospital chains, and [[Pharmacy Benefit Managers]]. Advocates cite it as proof that [[Vertical Integration]] can serve patients rather than shareholders; critics note it carries the same "nonprofit" tensions — large reserves, executive pay, labor disputes — as other big nonprofit systems.
