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.

In Preliminary Rate Filings, ACA Marketplace Insurers Largely Propose Double-Digit Premium Increase For 2027, Following a Steep Climb This Year

If these increases hold, typical premiums for insurers participating in the ACA Marketplaces would jump by more than one-third between 2025 and 2027.
