WASHINGTON — Enrollment in the U.S. individual health insurance market declined sharply through the middle of 2026 as rising premiums and concerns about the affordability of coverage placed additional pressure on households purchasing insurance outside employer-sponsored plans.
An analysis published by KFF on October 14 found that enrollment in the individual market fell 18% between June 2025 and June 2026. The number of people covered declined from approximately 25.2 million to 20.5 million, representing a reduction of more than 4.6 million enrollees.
The individual market includes Affordable Care Act marketplace plans and similar policies purchased directly from insurers. Approximately nine in ten people in this market obtain coverage through ACA marketplaces, making the enrollment decline an important indicator of changes in access to individual health insurance.
Premium costs are emerging as a major concern ahead of the next enrollment period. Insurers have proposed a median premium increase of 15% for marketplace plans in 2027, according to the KFF analysis. The proposed increases follow another year of significant premium adjustments and could make coverage more difficult to afford for families already managing housing, food and transportation expenses.
The financial impact will vary depending on household income, location, selected insurance plan and eligibility for government assistance. People who receive premium tax credits may experience different changes in their monthly payments from those who purchase coverage without subsidies. However, when assistance decreases or premiums rise faster than household income, some consumers may reconsider their coverage options.
For individuals who work for small businesses, are self-employed or do not receive health benefits through an employer, marketplace insurance can be an important source of protection. Losing coverage or deciding not to renew a policy can expose households to substantial medical expenses if they require emergency treatment, prescription medication or ongoing care.
Insurers are also watching enrollment trends because changes in the number and health profile of policyholders can affect the cost of providing coverage. If healthier consumers leave the market while people with greater medical needs remain enrolled, insurers may face higher average claims expenses. That could contribute to further premium increases in subsequent years.
The decline does not necessarily mean every person who left the individual market became uninsured. Some consumers may have moved to employer-sponsored plans, Medicaid or other forms of coverage. Others, however, may have found insurance too expensive or faced changes in eligibility and household circumstances.
The upcoming enrollment season will provide a clearer picture of how consumers respond to proposed 2027 premiums. Families will need to compare monthly costs, deductibles, provider networks, prescription benefits and out-of-pocket limits rather than focusing only on the advertised premium.
Policymakers and consumer advocates are likely to monitor whether rising costs lead to further coverage losses. Affordable insurance is important not only for household financial security but also for access to preventive care and treatment before medical conditions become more serious.
The latest figures highlight a growing challenge for the U.S. health insurance system: maintaining broad coverage while premiums and healthcare expenses remain under pressure. Whether enrollment stabilizes will depend on final premium rates, available financial assistance, consumer choices and the accessibility of alternative coverage options.
