ACA marketplace enrollment has declined sharply as premium increases have outpaced available subsidies, making coverage unaffordable for many Americans. Families who previously qualified for assistance now face higher out-of-pocket costs, and millions have dropped coverage or moved to off-exchange plans. Premium spikes vary by state and metal tier, but middle-income households that earn too much for enhanced subsidies have been hit hardest.

Why Premiums Are Rising

Health insurance premiums on the ACA marketplace are driven by medical cost trends, insurer risk pools, and regulatory changes. When insurers pay more in claims than expected, they raise premiums the following year to cover losses. Recent increases stem from higher prescription drug costs, hospital consolidation, and a return to pre-pandemic utilization patterns as policyholders resumed delayed care.

Many states saw double-digit premium hikes for 2026 plan years, particularly in markets with only one or two carriers. Limited competition removes downward pricing pressure, and when a dominant insurer holds most of the market share, premiums often climb faster than in states with robust carrier participation.

Subsidy Gaps and Affordability

Federal premium tax credits (subsidies) help lower-income enrollees afford marketplace coverage, but the benefit phases out at higher income levels. Enhanced subsidies introduced during the pandemic expired at the end of 2025, and Congress did not extend them. Households earning above 400 percent of the federal poverty level now face the full premium cost with no assistance.

For a family of four earning $120,000 annually, a Silver plan premium might reach $2,000 per month or more in high-cost regions, with no subsidy to offset the expense. Families in this income bracket are leaving the marketplace in large numbers, either going uninsured or turning to short-term limited-duration plans that cost less but offer narrower coverage and no guarantee of renewability.

Enrollment Decline and Coverage Gaps

Marketplace enrollment dropped by an estimated 3 million people between open enrollment for 2025 and 2026, reversing gains made during the pandemic when expanded subsidies and special enrollment periods brought record participation. Younger, healthier enrollees have been the first to leave, creating an older, sicker risk pool that pushes premiums even higher in a feedback loop insurers call adverse selection.

The uninsured rate is climbing again, particularly among working adults who earn too much for Medicaid but find marketplace premiums unaffordable. These individuals often delay care, incur medical debt, or rely on emergency rooms for treatment, shifting uncompensated care costs to hospitals and, indirectly, to other insured patients through higher prices.

What You Can Do

If marketplace premiums are too expensive, compare plans during open enrollment to find the lowest-cost option that meets your needs. Metal tiers (Bronze, Silver, Gold, Platinum) trade off premium cost against out-of-pocket expenses, and a high-deductible Bronze plan paired with a health savings account may work for healthy individuals who rarely use care.

Check whether you qualify for a subsidy by using the Healthcare.gov estimator tool, even if you were ineligible in prior years. Income changes, household size, and state of residence all affect subsidy eligibility. If you lose marketplace coverage due to cost, you may qualify for a special enrollment period if you experience a qualifying life event such as marriage, birth, or job loss with employer coverage.

Consult a licensed health insurance agent or navigator to explore all available options, including Medicaid (if your state expanded eligibility), employer-sponsored group plans, or professional association plans. Some states operate their own marketplaces with additional subsidy programs funded by state revenue.
