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 Bigger Story, and Agenda, Behind GOP Changes to Obamacare, Medicare and Medicaid

    From Drew Altman

    This column was published as a Wall Street Journal Think Tank column on November 21, 2016. Early media coverage of the Republican health-care agenda has concentrated on plans to repeal and then replace the Affordable Care Act. The larger story is GOP preparations for a health policy trifecta: to fundamentally change the ACA, Medicaid and Medicare–all three of health care’s major programs–and in the process, fundamentally alter the direction of the federal role in health and core elements…

    News Release
