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.

  • Data Note: How Many People Have Nongroup Health Insurance?

    Issue Brief

    The implementation of the Affordable Care Act (ACA) has focused attention on the composition of the nongroup market: how it looked before the new regulatory provisions take effect and how it will change afterwards. There are several ways of answering this question, depending on the time period for measuring enrollment and the information source. There is substantial turnover among people with nongroup coverage, which means that the number of people covered at the beginning of…

  • Polling Data Note: Beyond the ACA, the Affordability of Insurance Has Been Deteriorating Since 2015

    News Release

New survey findings from the Kaiser Family Foundation show that health care has become somewhat less affordable even among those with health insurance.

  • Implications of Reduced Federal Medicaid Funds: How Could States Fill the Funding Gap?

    Issue Brief

    In this analysis, we present three scenarios of reductions in federal Medicaid spending and examine fiscal implications if states fill these financing gaps to maintain their programs and if all reductions are assumed to be in full effect in FFY 2015 (the most recent year for which Medicaid spending data is available). To fill these gaps in financing and maintain current Medicaid programs, we assume states will increase state spending for Medicaid by increasing state…
