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.

    Issue Brief

    Education leaders and policymakers are turning to cellphone bans in schools to help address youth mental health concerns and improve learning, an idea that has largely received bipartisan support. Cellphone ban legislation has had a resurgence following advisories from the U.S. Surgeon General on youth mental health and the impacts of social media.

  • The Role of the Basic Health Program in the Coverage Continuum: Opportunities, Risks & Considerations for States

    Issue Brief

    This brief assesses the potential benefits and drawbacks to states from implementing a Basic Health Program under the Affordable Care Act.

  • Pre-X Redux

    From Drew Altman

    With the focus now mainly on exchanges, Medicaid expansions, and enrolling the uninsured in newly available coverage arrangements, there is less attention lately to the ACA insurance reforms which have always been the most popular parts of the law – changes which could affect every American’s insurance in some way and which go into effect regardless of the implementation decisions states make.  In this column, I draw on our recent tracking polls to review where…

  • On Medicaid Expansion, History Matters

    From Drew Altman

    In his latest column, KFF President and CEO Drew Altman discusses the history of the battles over the ACA’s provisions that were designed to expand coverage for the uninsured, which helps explain the effort to cut federal funding for the Medicaid expansion today.
