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.
