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.

  • What an Income Cap Could Mean for ACA Enrollees and the Federal Budget
