A recent KFF survey reveals that 9% of Americans enrolled in Affordable Care Act marketplace health plans in 2025 are now uninsured after enhanced federal subsidies expired, causing premiums to more than double and straining household finances.
Survey Methodology and Key Findings
- The nonpartisan KFF survey polled 1,117 U.S. adults who had ACA marketplace coverage in 2025, conducted from February 12 to March 2, 2026.
- Over 90% of ACA enrollees (approximately 22 million people) received enhanced subsidies in 2025, which lowered monthly premiums.
- With the subsidies' expiration, average premiums more than doubled for enrollees in 2026.
Impact on Insurance Coverage and Finances
- 9% of 2025 enrollees reported losing their health insurance entirely due to higher costs.
- 17% of returning enrollees lack confidence in affording their 2026 premiums, risking further coverage loss.
- Many households responded by downgrading plans or expressing significant worry about medical expenses if they become ill.
