The U.S. integrated delivery network (IDN) market is poised to reach over $4.2 trillion in value by 2035, fueled by the industry's transition from reactive to proactive, personalized care. By leveraging AI, digital health records, and remote monitoring, IDNs can enhance care coordination, predict health risks, and optimize resource allocation. However, high capital costs and supply chain volatility pose significant growth constraints.

Why it matters

The evolution of IDNs from volume-based to value-based care models is a major shift in the U.S. healthcare landscape. By integrating payers, providers, and post-acute services, IDNs can better manage the full patient journey and drive improved outcomes. This transformation is critical as the industry focuses on population health, chronic disease management, and cost containment.

The details

Vertical integration, where IDNs combine insurers and hospitals under one entity, is the dominant model, allowing for holistic care management. Horizontal expansion through mergers and acquisitions also enables IDNs to gain economies of scale and strengthen their negotiating power. The acute care segment leads the market, but primary care is growing fastest as IDNs invest in preventative services to reduce costs and enhance quality.

  • The U.S. IDN market was valued at $2.8 trillion in 2025.
  • The market is projected to surpass $4.2 trillion by 2035, growing at a CAGR of 4.2%.
