Around 22 million Americans received enhanced federal subsidies for Affordable Care Act (ACA) marketplace health insurance in 2025. However, the expiry of these subsidies, which were designed to reduce monthly premiums, left every 1 in 10 people enrolled in an ACA marketplace health plan last year uninsured.
The health policy research group KFF found in its latest survey of 1,000 US adults enrolled in an ACA marketplace health plan in 2025 that the expiry of subsidies also compelled millions of people to downgrade their health insurance amid higher premiums and rising unemployment.
