ACA Health Insurance Enrollment Drops by 1.4 Million in 2026: A State-by-State Look
In 2026, the number of Americans enrolled in health insurance plans through the Affordable Care Act (ACA) marketplaces has declined by 1.4 million compared to the previous year, according to recent data from the Centers for Medicare & Medicaid Services (CMS). This significant drop is causing concern among health policy experts and could signal rising challenges for low- and middle-income Americans as they confront higher health insurance costs without critical subsidy support.
States with the Largest Enrollment Declines
The decline in ACA marketplace enrollment has been especially pronounced in Southern and Southeastern states. Florida experienced the steepest reduction, with over 260,000 fewer enrollees. Other states witnessing major dips include Ohio, North Carolina, and Georgia. In contrast, some states like Texas and California bucked the trend, recording enrollment increases. California’s uptick is partly attributed to its state-level ACA subsidy program, which has shielded residents from the full impact of the federal subsidy expiration.
Impact of Subsidy Discontinuation on Costs and Enrollment
The expiration on December 31, 2025, of enhanced ACA subsidies—which had been in effect since 2021—has led to rising premiums and out-of-pocket expenses for many Americans. These enhanced subsidies had previously made health insurance more affordable for individuals and families with incomes up to 400% of the federal poverty level, which equals approximately $128,600 annually for a family of four.
The Kaiser Family Foundation (KFF) estimates that without these credits, those enrolled in marketplace plans could see their premium costs more than double compared to the previous year. Consequently, many enrollees, particularly low- and middle-income households, are facing “sticker shock” that may be forcing them to reconsider their insurance coverage.
Expert Analysis on Health and Financial Consequences
Matthew Fiedler, a senior fellow at The Brookings Institution, highlighted the broader consequences of declining ACA enrollment. "People have less access to care, and that tends to translate into worse health outcomes," Fiedler said. He further warned about the financial repercussions: "People will face big bills that they either can’t pay, and that hurts their credit. Or they do pay, but it requires them to skimp in other areas."
The potential increase in uninsured individuals could further strain healthcare providers, especially hospitals already facing financial challenges. Fiedler cautioned, “There will be facilities that were already financially fragile for whom this is the straw that breaks the camel’s back," emphasizing that a rise in uninsured patients seeking care would intensify these pressures.
Political Context and Congressional Impasse
The subsidy lapse has been a contentious political issue contributing to the recent government shutdown. Despite ongoing debates, lawmakers did not renew the enhanced subsidies in December 2025, and further legislative action remains stalled in the Senate.
White House spokesperson Kush Desai attributed the enrollment decline to efforts initiated by the prior administration, claiming the 3.5% drop between 2025 and 2026 was "entirely a result of the Trump administration’s commonsense measures to cut waste, fraud, and abuse and remove people who were improperly enrolled on highly-subsidized ACA plans."
Meanwhile, a healthcare plan released by former President Donald Trump on January 15 focuses on lowering drug prices, reducing premiums, and increasing cost transparency but notably does not propose renewing ACA subsidies.
Gideon Lukens of the Center on Budget and Policy Priorities critiqued this approach as contradictory and lacking clear mechanisms to prevent the premium spikes millions of Americans now face.
Anticipated Further Declines
Experts warn that the January data available only reflects enrollment during the open enrollment period or automatic renewals. It does not account for how many enrollees have paid their premiums. Analysts expect the enrollment figures to drop further in the coming months as households receive medical bills and premiums they cannot afford.
Matthew Buettgens, a senior fellow at The Urban Institute, explained, "Many likely signed up when the premiums they would end up facing were uncertain and then waited to see what they would have to pay."
Additionally, a recent Congressional Budget Office report forecasts that nearly 4 million Americans could lose or drop their health insurance coverage over the next decade if current trends continue.
What This Means for Americans
For millions of Americans who rely on the ACA marketplaces—especially those without employer health plans or who earn too much to qualify for Medicaid—the loss of subsidies equates to significant financial hardship. The increases in premiums and out-of-pocket costs may force many to forgo coverage altogether, potentially leading to worse health outcomes and exacerbating financial instability.
As policymakers remain deadlocked, stakeholders and advocates are calling for urgent action to renew and extend subsidy support to prevent further erosion of healthcare access for vulnerable populations.
