What We Know about Trump’s $500 ACA Checks and the User Fees Funding Them

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.

Individual Market Enrollment Declined by 18% Since June 2025

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 enrollment decline coincides with the expiration of the enhanced premium tax credits and other policy changes that are expected to reduce enrollment.
