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.

    Other Post

    This Visualizing Health Policy infographic examines the effect of decisions by states in the South to implement or forgo the Affordable Care Act Medicaid expansion.

  • How Obamacare’s Progress Makes Expanding Coverage Harder

    From Drew Altman

    This was published as a Wall Street Journal Think Tank column on July 21, 2014. The Affordable Care Act’s success meeting its initial enrollment goals and the repair of HealthCare.gov seem to have calmed the political waters for Obamacare. But the job of enrolling the uninsured gets harder, not easier, because the remaining uninsured will generally be tougher to reach. Recent surveys show, roughly in line with expectations, that 8 million to 9.5 million fewer adults are uninsured compared with last year before…
