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 

ACA Marketplace insurers are proposing a median premium increase of 14% for 2027— indicating a likely second consecutive year of double-digit increases, according to a new analysis of preliminary rate filings in 16 states and DC. If these increases hold, typical premiums for insurers participating in the ACA Marketplaces would jump by more than one-third between 2025 and 2027.

  • Implementing the ACA’s Medicaid-Related Health Reform Provisions After the Supreme Court’s Decision

    Issue Brief

    On June 28, 2012, the U.S. Supreme Court upheld the constitutionality of the Affordable Care Act (ACA). A majority of the Court also found the ACA’s Medicaid expansion unconstitutionally coercive of states, while a different majority of the Court held that this issue was fully remedied by limiting the Health and Human Services (HHS) Secretary’s enforcement authority. The practical effect of the Court's decision makes the Medicaid expansion optional for states. This brief addresses questions…

  • Pulling It Together: Predicting the Future

    Perspective

    A fair amount of attention was given recently to projections made by the Chief Actuary of the Centers for Medicare and Medicaid Services (CMS) about the new health reform law, and how they compare to previous estimates by the Congressional Budget Office (CBO).
