How Has Marketplace Enrollment Changed Across States in 2026?

Following several years of rapid enrollment growth in the ACA Marketplaces that corresponded with temporary enhanced premium tax credits, enrollment fell for the first time in seven years in 2026, when those tax credits expired. Every state except for New Mexico saw a drop in Marketplace enrollment from 2025 to 2026. State-based Marketplaces that run their own enrollment platforms, including those that partially offset the enhanced tax credits, generally saw lower drops in enrollment.

  • Liking the Pieces, Not the Package: Contradictions in Public Opinion During Health Reform

    Poll Finding

    Public opinion played a prominent role during the recent health care reform debate. In a published Health Affairs article, Kaiser researchers examine past and present polling and show that opinion tracked with historic patterns and was relatively stable, even if the contentious public debate suggested a volatile public mood in 2009 and 2010. Going forward, the public will begin reacting to reform implementation, primarily by judging it in terms of their perceptions of and experiences…

  • Pulling It Together: Rising Health Costs Are Not Just a Federal Budget Problem

    Perspective

    Premiums for employer-provided health insurance, where 150 million Americans get their coverage, jumped 9% in 2011 while workers’ wages grew just 2%, according to our annual employer survey.  The average family policy now costs more than $15,000 per year, more than the cost of a Chevy Aveo or a Ford Fiesta.  Since we began doing this survey thirteen years ago, worker contributions to premiums have increased 168%, wages 50%, and inflation 38%. Critics of the…

  • Small Area Variations and the ACA’s Coverage Expansions

    From Drew Altman

    A new Kaiser analysis sheds light on how the country might react to the Affordable Care Act (ACA) when it is implemented.  It looks at how the benefits of the ACA's coverage expansions will vary around the country by census areas (technically, Public Use Microdata Areas, or PUMAs).  PUMAs are artificial areas of about 100,000 people each created by the Census Bureau to provide more detailed demographic, social and economic information at the local level.  They…

  • I notice something called “Easy pricing” under the plan name on HealthCare.gov. What does that mean?

    FAQs

    "Easy pricing" refers to a "standardized" plan design on HealthCare.gov that aims to make it simpler to compare plans by applying the same to each category of essential health benefits across all easy pricing plans in the same metal level. For example, all Bronze-level easy pricing plans have the same deductible and copays. By contrast, non-standardized Bronze-level plans might have different deductible and copay amounts. Easy pricing plans are marked with a green circle with…
