Provider total-cost-of-care risk contracts Market Outlook 2026–2034: Growth Drivers, Key Companies, Strategic Developments & Adoption Forecast — A Meticulous Next™ Foresight Brief

This Meticulous Next™ brief examines provider total-cost-of-care risk contracts, where provider organisations accept responsibility for the total cost and quality of care of a defined group of patients and share in the savings or losses against a set benchmark. It tests how far total-cost-of-care contracts replace fee-for-service payment for primary care by 2034, and what that means for providers, payers and health systems.

Accountable care is growing steadily. CMS estimated that 14.3 million Medicare beneficiaries were in an accountable care organisation in January 2026, up from 13.7 million in 2025, a rise of 4.4%, and the Medicare Shared Savings Program grew from 476 to 511 organisations. The conclusion is that accountable care is still adding patients and organisations each year, and the shared savings route is the largest entry point to risk contracts.

Payouts are already large. CMS reported performance payments of USD 4.1 billion to Shared Savings Program organisations for performance year 2024, with 75% of the 476 organisations earning savings and net per capita savings of USD 319 for low revenue organisations and USD 180 for high revenue organisations. The conclusion is that risk contracts pay well for organisations that manage spending, and the higher saving per patient at low revenue organisations shows that smaller groups can match larger ones on cost control.

The federal model is being reset. CMS announced the Long-term Enhanced ACO Design model in December 2025, which runs for ten years from 1 January 2027 to 31 December 2036 and offers a global risk option with up to 100% of savings and losses and a professional risk option with up to 50%. The conclusion is that a ten year horizon gives organisations time to invest in care management and move from shared savings toward full risk.

The federal goal sets the pace. CMS has set a goal of placing all traditional Medicare beneficiaries in an accountable care relationship by 2030, and roughly 51% were in such a relationship by July 2026. The conclusion is that about half of the target is already met, and the remaining growth must come from smaller, rural and independent practices that the new model is designed to include.

The brief treats provider total-cost-of-care risk contracts as an accelerating signal with an eight year horizon to 2034. It identifies which provider groups, payers and health systems move first and what each means for revenue, risk and patient access. It is a focused 112-page decision brief that presents an indicative trajectory rather than a segmented market model.

The shared savings contract is the core model. In 2026 the Shared Savings Program has 511 organisations, more than 700,000 providers and 12.6 million beneficiaries, up 12.3% from 2025, and ACO REACH has 74 organisations with about 1.7 million beneficiaries. The conclusion is that the Shared Savings Program is the main route into risk for most organisations, and REACH serves a smaller group that takes more risk.

Specialty and condition contracts are growing at the edges. Kidney Care Choices has 74 kidney contracting entities serving 237,000 beneficiaries and ACO PC Flex has 23 organisations serving 359,720 beneficiaries. The conclusion is that risk contracts now reach specialty care and prospective primary care payment, although they remain small beside the Shared Savings Program.

Primary care groups show what risk contracts can deliver. agilon health, inc. had eight ACOs in ACO REACH covering more than 120,000 Medicare beneficiaries in 2024, with an average quality score of 96, and saved the Medicare Trust Fund more than USD 54 million. The conclusion is that risk-bearing primary care groups can lower spending while keeping quality high, which supports further growth of risk contracts.

Medicare Advantage extends risk contracts to private plans. About 30% of Medicare Advantage patients are in physician-led, risk-based arrangements, according to a landscape survey cited in July 2026. The conclusion is that Medicare Advantage already pushes risk to providers on a large scale, and federal ACO models and private plan contracts are growing in parallel.

The limits are financial losses at some risk-bearing groups, the burden of quality and fraud oversight, and the limits of evidence and attribution. The brief tests each limit against the contract evidence to 2034.

The provider total-cost-of-care risk contracts market, covering shared savings, performance and risk-sharing payments earned by provider organisations under total-cost-of-care contracts with Medicare, Medicare Advantage, Medicaid and commercial payers, measured by annual shared savings and risk-sharing payments received by provider organisations, and excluding fee-for-service payments, premium revenue kept by health plans, and pay-for-performance bonuses that are not tied to total cost of care, is valued at USD 8–12 billion in 2026 and is projected to reach USD 19.81–29.71 billion by 2034, at a CAGR of 12%.

The 2026 base rests on shared savings and risk-sharing payments earned under the Shared Savings Program, ACO REACH and related federal models, with Medicare Advantage, Medicaid and commercial contracts added. Growth then follows the number of beneficiaries in risk contracts, the move of organisations from shared savings toward full risk and the entry of Medicaid and episode contracts.

The forecast is sensitive to the benchmark rules of federal models, the share of beneficiaries in Medicare Advantage and the share of contracts that move to full risk.

The base case assumes steady growth in beneficiaries and organisations under risk contracts, bringing the inflection to about 2029 and a 2034 value near the middle of the range. An accelerated case assumes fast movement to full risk under the LEAD model and wider Medicaid and commercial contracts, bringing the inflection to 2028 and lifting the 2034 value to the top of the range. A delayed case assumes losses at risk-bearing groups and tighter benchmark rules, moving the inflection to 2031 and holding growth at the bottom of the range.

Growth drivers

• Payer demand for lower total cost of care.
• Provider need for steady and predictable revenue.
• Federal goals for accountable care.
• Growth of Medicare Advantage enrolment.

Enablers

• Care management and analytics tools.
• Provider and payer contracts.
• Contract and project evidence.
• Primary care and enablement partnerships.

Restraints and barriers

• Price pressure and return on investment.
• Financial losses at some risk-bearing groups.
• Quality and fraud oversight burden.
• Differences in national payment and risk adjustment rules.

The direction of provider total-cost-of-care risk contracts is set by payer demand for lower total cost of care, provider need for steady and predictable revenue, federal goals for accountable care, care management and analytics tools, and the readiness of providers to carry financial risk.

The key participants in provider total-cost-of-care risk contracts and value-based care include UnitedHealth Group Incorporated, Humana Inc., CVS Health Corporation, Elevance Health, Inc., Centene Corporation, The Cigna Group, Molina Healthcare, Inc., agilon health, inc., Privia Health Group, Inc., Evolent Health, Inc., Clover Health Investments, Corp., Alignment Healthcare, Inc., Astrana Health, Inc., P3 Health Partners Inc., HCA Healthcare, Inc., Tenet Healthcare Corporation, DaVita Inc., InnovAge Holding Corp., The Oncology Institute, Inc., Community Health Systems, Inc., Oscar Health, Inc., NeueHealth, Inc., Kaiser Foundation Health Plan, Inc., CommonSpirit Health, Ascension, Mayo Clinic, Cleveland Clinic, Advocate Health, Inc., Blue Cross Blue Shield Association, Oracle Corporation, Microsoft Corporation, Amazon.com, Inc., Innovaccer Inc., Epic Systems Corporation, Health Catalyst, Inc., Teladoc Health, Inc., the Centers for Medicare & Medicaid Services, the Department of Health and Human Services, the Medicare Payment Advisory Commission, the National Committee for Quality Assurance and the Health Care Payment Learning and Action Network.

The brief profiles representative participants in each archetype and assesses which are positioned to lead as full-risk and Medicaid integrated contracts reach scale.

UnitedHealth Group Incorporated, Humana Inc. and CVS Health Corporation lead among Medicare Advantage payers, agilon health, inc., Privia Health Group, Inc. and Astrana Health, Inc. lead among risk-bearing physician groups, and HCA Healthcare, Inc. and Tenet Healthcare Corporation lead among hospital groups. Competitive intensity is rising as payers buy physician groups and independent practices join accountable care organisations.

Where value migrates.

In 2026 value sits with large payers and with physician groups that hold shared savings contracts in the Shared Savings Program and ACO REACH. By 2029 it moves toward organisations that carry full risk and link Medicaid and Medicare patients, because the LEAD model rewards groups that manage the total cost of care. By 2034 it settles with total-cost-of-care contracts as the standard route for primary care, where data, care management capacity and sound risk adjustment carry the margin. Margins hold for groups with strong primary care networks, and narrow for those that take risk without the data and care management to control spending.

Rising participation, large shared savings payouts and a ten year federal model support growth, while losses at some risk-bearing groups, the burden of quality and fraud oversight, and limits of attribution hold back the pace.

Benchmark changes, losses at risk-bearing groups or tighter rules could slow progress. The brief therefore tracks four indicators: savings per beneficiary and payout levels, beneficiaries in risk contracts, organisations in risk contracts and the share of contracts at full risk.

Shared savings contracts first, then full-risk and Medicaid integrated contracts at scale, then standard status for total-cost-of-care contracts is the expected order of change.
