With the Affordable Care Act’s (ACA) enhanced premium tax credits set to expire at the end of 2025, a large majority (77%) of the public favor Congress extending the credits while about one in five (22%) say they should let them expire, the latest KFF Health Tracking Poll finds.
This policy watch discusses key provisions in the draft 2025 budget reconciliation legislation that are aimed at limiting health coverage for immigrant families.
Taken together, the reconciliation bill's provisions impose additional administrative burdens on state-based marketplaces and could limit state flexibility in choosing marketplace policies and procedures.
This chart examines individual market enrollment data from 2011 through 2025, when enrollment reached a record high of 25.2 million people. Affordable Care Act (ACA) Marketplace enrollment increased following the enactment of enhanced premium tax credits in 2021, as more individuals became eligible for subsidies.
On May 22, 2025, the U.S. House of Representatives passed a budget reconciliation bill that includes significant reductions in federal Medicaid spending to help offset the cost of tax cuts, along with changes to the Affordable Care Act (ACA), immigration reforms and other provisions. This issue brief discusses the potential implications of the bill for hospitals and explains how some hospitals (such as rural hospitals as well as urban hospitals that serve a large share of Medicaid patients) may be less well positioned than others (such as hospitals that serve a large share of commercial patients) to absorb revenue losses given their current financial status.
Through regulations and the House budget reconciliation bill, significant changes are being considered by Congress and the Trump Administration for how the Affordable Care Act’s health insurance Marketplaces would work. To examine how these changes could reshape the ACA’s Marketplaces, KFF held a virtual briefing on June 11 featuring leaders from two state-based Marketplaces to get perspectives from the field.
In his latest column, President and CEO Drew Altman discusses how, with nearly half, or about 10 million MAGA supporters and Republicans receiving coverage through the ACA Marketplaces, the policy changes and cuts being considered by Republicans to the Marketplaces will directly affect their own voters. Altman writes: "Republicans are no longer interested in repealing the ACA but seem comfortable shrinking it significantly if they can, so long as they don’t touch protections for pre-existing conditions, which is now a political third rail."
ACA Marketplace changes are technical and numerous but consequential. While more attention has been focused on cuts to Medicaid, upcoming changes to the ACA Marketplaces could lead to just as many people losing health insurance coverage.
As Congress works to pass the "One Big Beautiful Bill Act," which includes significant changes to Medicaid and the ACA, the latest KFF Health Tracking Poll examines the views of groups that could be most directly impacted by the impending legislation. The poll finds most of the public is worried about the consequences of federal funding reductions to Medicaid, including rural residents, those with lower incomes, and across partisans.
As Congress weighs spending cuts and other changes to Medicaid, more than half (54%) of the public say they are worried significant reductions in federal Medicaid spending would negatively affect their family’s ability to obtain and afford health care, a new KFF Health Tracking Poll finds.
