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.

    News Release

    Medicaid coverage of acute and long-term care for more than 6 million low-income seniors and 10 million nonelderly people with disabilities accounts for nearly two-thirds of overall Medicaid spending, although such enrollees represent less than a quarter of people on Medicaid.  Much of Medicaid’s spending on seniors and people with disabilities also depends on state decisions about whom to cover and which services to pay for, which is a big reason why Medicaid spending per…

  • I heard the Affordable Care Act’s individual mandate ended. Does it still make sense to sign up?
