The ACA MarketplaceS

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.

    Perspective

    Regular readers of the Kaiser Health Tracking poll know by now that public opinion on the Affordable Care Act (ACA) has been at a steady cruising altitude since it was signed into law on March 23, 2010, with a little over four in ten viewing the law favorably and a similar share unfavorably. But, has public opinion on the law since passage been more turbulent for different groups of Americans, for example, those with lower…

  • The ACA and Fluoridation: The Power of Political Symbols

    Perspective

    In the 1950s, water fluoridation became a public health controversy that morphed into a symbolic issue of larger proportions. For its opponents, fluoridation came to symbolize big government and even for some, a communist threat. The controversy became so odd that it was parodied in Stanley Kubrick’s 1964 film “Dr. Strangelove,” in which General Jack Ripper starts a nuclear war to stop a communist plot to “sap and impurify all of our precious bodily fluids”…

    Perspective

    As the Patient Protection and Affordable Care Act (ACA) nears its second birthday, the latest Kaiser Health Tracking Poll finds that public opinion on the law remains evenly split (41 percent favorable, 40 percent unfavorable) with sharp divisions along partisan lines, much as it has been since the law was passed. With the Supreme Court preparing to hear challenges to the law later this month, about half the public thinks the Court should strike down the…

  • Health Insurance Transparency under the Affordable Care Act

    Perspective

    In February, a final rule was issued implementing the Affordable Care Act (ACA) requirement that all health plans provide a uniform summary of coverage for all enrollees and applicants. The idea of providing easy-to-understand summaries of coverage is, in fact, the most popular provision in the ACA, according to a recent Kaiser tracking poll. That finding suggests powerful consumer frustration over the complexity of health insurance and the difficulty people face evaluating health insurance choices and understanding…

  • 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…

As the lawyers, policy makers, ACA opponents and supporters focus intently on the Supreme Court hearings, this Data Note looks at what the general public thinks of the mandate, explores the reasons why favorability ratings have been so low, and suggests that while opinion on…

    Feature
