Key Facts
- KFF analysis said average monthly effectuated ACA marketplace enrollment could fall to about 17.5 million in 2026 and could be as low as 16.5 million.
- KFF said 2025 average monthly effectuated enrollment was 22.3 million.
- KFF reported higher premiums and deductibles after the expiration of enhanced premium tax credits.

Higher health insurance costs could push millions of people out of Affordable Care Act marketplace coverage in 2026, according to new health policy analysis.

For families, freelancers, small-business owners, early retirees and others who buy their own insurance, the issue is practical: a plan can become harder to keep if the monthly premium rises, and harder to use if the deductible rises too.
Why Premiums and Deductibles Both Matter
Health insurance costs hit households in two different ways. Premiums are the monthly bill people pay to keep coverage. Deductibles are what many people must pay out of pocket before insurance covers much of their care.
That means a person can feel squeezed even if they technically still have insurance. A higher premium can make it harder to keep a plan. A higher deductible can make someone hesitate before scheduling care, filling a prescription or following up on a medical issue.
KFF reported higher premiums and deductibles after the expiration of enhanced premium tax credits. Health policy summaries reported average deductibles rose by about $1,000 per person. Those changes do not affect every household in the same way, but they point in the same direction: more of the cost burden can land directly on people buying marketplace coverage.
Who Could Feel the Change
ACA marketplace coverage is especially important for people who do not get insurance through an employer, Medicare, Medicaid or another public program. That can include self-employed workers, contract workers, small-business owners, people between jobs and early retirees who are not yet eligible for Medicare.
For those households, the marketplace may be the main path to coverage. If the cost of that coverage rises too much, some people may choose a cheaper plan with a higher deductible. Others may decide not to keep marketplace coverage at all.
The available source material does not show how many people who leave marketplace coverage would become uninsured versus move to other coverage. That distinction matters. Losing marketplace coverage does not always mean losing insurance entirely, but for some households it could.
A Projection, Not a Final Count
The KFF figures are projections based on what is known so far, not final 2026 enrollment totals. That is important because health insurance enrollment can change as people shop, compare plans, respond to price changes or qualify for other coverage.
The American Hospital Association summarized the KFF analysis as showing marketplace enrollment could fall by at least 17% in 2026. That gives readers a sense of the potential scale, but it should still be read as a projection rather than a completed outcome.
The clearest confirmed point is that analysts are warning of a major enrollment drop tied to higher costs. What is not yet settled is where the final number will land.
What Remains Unclear
Several questions remain open.
Final 2026 effectuated enrollment totals are not yet known. It is also unclear how many people who leave marketplace coverage will become uninsured, how many will move to another kind of coverage, and whether Congress or states will act to offset cost increases.
Those unknowns matter because the real-world impact will depend on household choices and policy decisions. A cost increase may be manageable for one family and impossible for another. A deductible increase may be a budget inconvenience for one person and a reason to delay care for someone else.
The Household Budget Issue
This story can easily become a partisan health-care argument. For readers trying to manage bills, it is first a household budget issue.
When premiums rise, the monthly math changes. When deductibles rise, the risk of a large medical bill changes. When both rise at once, people may face a harder choice between keeping coverage, changing plans or going without care they would otherwise seek.
The careful takeaway is this: KFF projects ACA marketplace enrollment could fall in 2026 as premiums and deductibles rise. The final numbers are not yet known, and the policy response remains uncertain. But for millions of people who buy their own insurance, the cost of coverage may become a more difficult part of the family budget.
