Individual Market Enrollment Fell 18%, Suggesting Continued ACA Marketplace Losses

Enrollment in the individual health insurance market fell by 18%—over 4.6 million people—from 25.2 million in June 2025 to 20.5 million in June 2026. Falling individual market enrollment suggests further decline in ACA Marketplace enrollment this year, since Marketplace enrollees represent the vast majority of individual market coverage.

  • The Individual Mandate: How Sweeping?

    Perspective

    The so-called "individual mandate"  – the provision under the Affordable Care Act (ACA) that requires most individuals to carry a minimum level of insurance coverage and is now being considered by the Supreme Court – has emerged as the least popular element of the reform law and the prime target for its opponents. Yet in practice, the mandate may not be quite as far-reaching as the controversy over it suggests. The vast majority of Americans already…

  • Public Opinion on the ACA: Cruising or Turbulent Ride?

    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…

  • Kaiser Health Tracking Poll — March 2012

    Feature

    As the oral arguments on the Affordable Care Act (ACA) begin in two weeks before the Supreme Court, the March Kaiser Health Tracking Poll finds that Americans' views on the case mirror their views on the health reform law and that they expect parts of the ACA to continue whatever the Court rules. The poll finds that half of all Americans (51%) think the Court should rule the mandate unconstitutional and about the same number…

  • 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”…

  • March Kaiser Health Tracking Poll: The ACA at Two Years; The Individual Mandate and the Supreme Court

    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…
