The ACA MarketplaceS

Change in February effectuated enrollment, by state, 2025-2026

How Has ACA Marketplace Enrollment Changed Across States in 2026?

ACA Marketplace enrollment fell this year in every state except New Mexico, which was the only state to fully replace the enhanced premium tax credits that expired last year with a state-funded subsidy, according to a new KFF analysis of effectuated enrollment data. The Marketplace enrollment decline—the first in seven years—follows several years of rapid enrollment growth and coincides with the end of the enhanced federal subsidies.

How Much and Why ACA Marketplace Premiums Are Going Up in 2027

ACA Marketplaces insurers are proposing a median premium increase of 15% in 2027, according to KFF’s updated analysis of 276 insurers with publicly available filings across all 50 states and the District of Columbia. This is the second consecutive year of double-digit premium hikes. Last year’s median nationwide proposed rate change was 18%, and the median finalized rate change was 20%. While this proposed rate change is lower than last year, it represents the second-highest requested rate change since 2018, as premium growth had been relatively flat in this market for several years.

  • The Affordable Care Act and Insurance Coverage in Rural Areas

    Issue Brief

    Rural populations face disparities compared to metropolitan populations in health care. While rural individuals were not more likely to be uninsured than metropolitan counterparts pre-Affordable Care Act, they were poorer and less likely to have private insurance. With coverage changes in the ACA involving an expansion of Medicaid for poor and near-poor populations, decisions by states with large rural populations may cause rural residents to have disparate access to coverage, which may exacerbate cost and…

  • What’s Driving the GOP Health Plan

    From Drew Altman

    This was published as a Wall Street Journal Think Tank column on May 30, 2014. Conservative House Republicans are pushing for a vote on a GOP health-care plan, presumably to appeal to their base, to give GOP candidates health reform ideas to talk about on the campaign trail and to show that they have a policy position beyond repealing the Affordable Care Act.
