ACA enrollment plunged by 1.4M. These states saw the biggest swings

Affordable Care Act marketplaces are facing their sharpest setback in years, with 1.4 m fewer people signed up for coverage heading into 2026 compared with a year earlier. The national decline masks even more dramatic shifts at the state level, where some places saw enrollment crater while others managed modest gains. The result is a fragmented map of coverage that tracks closely with premium spikes, the loss of enhanced subsidies, and long‑standing political choices about how aggressively to support the ACA.

Behind the topline drop are millions of households confronting sudden “sticker shock” as temporary tax credits vanish and insurers raise prices. Low‑ and middle‑income Americans who had come to rely on generous discounts are now weighing whether to downgrade plans, switch to skimpier alternatives, or leave the marketplace altogether. The geography of those decisions tells a larger story about health care affordability and the uneven safety net that has emerged across the country.

The national picture: 1.4 m fewer signups and rising costs

National enrollment data show a clear reversal from the ACA’s recent growth streak, with 1.4 m fewer Americans choosing marketplace plans for 2026 than in the prior year. Early federal figures already pointed to trouble, with officials reporting that Nationally around 800,000 fewer people had selected plans partway through open enrollment, a 3.5% drop from the same point a year earlier, before the final tally confirmed the deeper slide. Analysts tie that shift directly to the disappearance of enhanced Affordable Care Act subsidies that had temporarily shielded consumers from rising premiums and kept net prices unusually low.

At the same time, insurers filed for sizable premium hikes in many markets, compounding the impact of lost tax credits. Benchmark silver plans, which are used to calculate subsidies, are climbing sharply in several states, and research that tracks where ACA benchmark premiums are rising the most in 2026 highlights how those increases cluster in particular regions. As premiums move into the high single digits or low‑teens range in percentage terms, more Americans are being priced out of comprehensive Affordable Care Act Marketplace coverage and pushed toward cheaper, less generous options or into the ranks of the uninsured.

States with the steepest enrollment drops

The overall decline is not evenly distributed, and some states are bearing a disproportionate share of the 1.4 m loss. In Florida, which has long been a bellwether for ACA signups, marketplace selections fell more than in any other state, according to enrollment tallies that show it leading the nation in decreases. Officials there report that Nationally around 800,000 fewer people had chosen plans at a comparable point in the sign‑up window, and Florida’s share of that drop was outsized, reflecting both high prior enrollment and acute sensitivity to premium changes. Similar patterns are emerging in Texas and Georgia, where large populations of low‑income workers had used the ACA as their primary route to coverage and are now confronting higher out‑of‑pocket costs.

Midwestern and Southern states that rely on the federal marketplace and have not expanded Medicaid are also seeing pronounced declines. Enrollment has slipped in Ohio, where many rural residents and small‑business owners had turned to ACA plans, and in Arkansas, which is projected to see the largest percentage increase in average ACA benchmark premiums in 2026. In those markets, the combination of higher sticker prices and the end of enhanced subsidies is particularly potent, since there are fewer alternative coverage options and incomes are often too high for traditional Medicaid but too low to comfortably absorb premium hikes.

Where enrollment held up or even grew

Not every state followed the national trend. A ranking of states by ACA enrollment change since 2025 shows that New Mexico recorded the biggest increase in signups, bucking the national decline. That growth reflects a mix of aggressive outreach, state‑level affordability measures, and a relatively robust safety net that helps residents navigate shifting federal rules. Other states with their own marketplaces or strong consumer assistance networks, such as Washington and New York, have managed to keep enrollment comparatively stable by layering state subsidies or public‑option‑style plans on top of federal assistance.

Smaller jurisdictions also stand out. The District of Columbia is seeing benchmark premiums rise around 5% according to research that tracks Where ACA benchmark rates are moving, yet its long‑standing commitment to robust Medicaid coverage and local subsidies has helped cushion residents. States like Vermont and Minnesota have long experimented with state‑based reinsurance and supplemental aid, which helps blunt premium spikes and may explain why their enrollment swings are less severe than in high‑premium, low‑support states.

Premium spikes, lost subsidies and the role of Congress

Underneath the enrollment map is a straightforward affordability story. As millions of Americans shop for 2026 coverage, Affordable Care Act Marketplace premiums have climbed into the high single digits and even the low‑teens range in some states, according to analyses of the 10 states with the biggest hikes. Separate research that focuses on Where ACA benchmark premiums are rising the most in 2026 identifies Arkansas as facing the largest percentage jump in its benchmark plan, with the District of Columbia also seeing a 5% increase. Those benchmark figures matter because they set the level of federal tax credits, so when they rise quickly in places without extra state help, consumers feel the full brunt.

The policy backdrop is equally important. Congress failed to reach an agreement on extending the enhanced subsidies before the end of last year and still has not reached one, leaving households exposed just as premiums spike. As a result, 1.4 m fewer people enrolled in ACA plans as premiums rise and tax credits expire, a dynamic that advocates describe as a Health Care Affordability Crisis rather than a temporary blip. Consumer groups argue that these outcomes are not random, pointing to the way the disappearance of Affordable Care Act subsidies has produced immediate sticker shock for Low and middle‑income Americ families who had finally gained stable coverage during the subsidy expansion period.

How state politics and local markets shape the swings

State policy choices and local market structures go a long way toward explaining why some places saw enrollment plunge while others held steady. In Florida, for example, the decision not to expand Medicaid and to rely on the federal marketplace has left many low‑wage workers in a coverage gap, so any increase in premiums or reduction in subsidies quickly shows up as a drop in signups. Similar dynamics are at work in Georgia and Texas, where partial or delayed coverage expansions and limited insurer competition have kept premiums relatively high. In contrast, states like Washington and New York have layered public‑option‑style plans and state subsidies on top of federal aid, which helps keep net premiums manageable even as underlying costs rise.

Local markets also matter. In Illinois and Virginia, relatively competitive insurer landscapes have helped moderate premium growth, which may be one reason their enrollment declines are less severe than in neighboring states with more concentrated markets. Meanwhile, North Carolina is in the midst of a complex transition as it expands Medicaid while still relying heavily on marketplace coverage, creating churn that can temporarily depress signups even as overall coverage improves. The interplay of these factors shows up clearly in state‑by‑state rankings of ACA enrollment change since 2025, where New Mexico sits at the top while others fall far behind.
