This analysis examines the $500 checks that the Trump administration is sending to some Affordable Care Act Marketplace enrollees and the user fees that are paying for them. The checks are going to about 1 million enrollees in the 30 states that rely on the federal HealthCare.gov Marketplace who are not receiving any tax credits this year – a small share of the 19.2 million people who were enrolled nationally as of February.

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.
KFF’s new interactive maps illustrate ACA Marketplace enrollment and changes in enrollment by congressional district and state. Marketplace enrollment declined in most congressional districts between 2025 and 2026, with two-thirds of the decline (67%) occurring in Republican-held congressional districts.
More people than ever got coverage through the Affordable Care Act (ACA) Marketplaces in 2025, but the expiration of enhanced premium tax credits has driven up what people pay and contributed to declining enrollment in 2026. Law and regulatory changes also tightened ACA eligibility and enrollment requirements. Public opinion of the ACA remains generally favorable, although views remain divided along partisan lines.
