Eroding ACA Enrollment Portends Higher Insurance Rates - KFF Health News

Enrollment in the Affordable Care Act continues to erode as some customers struggle to make premium payments, with the declining numbers churning market uncertainty for insurers. In response, insurers are likely to raise rates again next year, following this year’s larger-than-typical hikes.

A KFF analysis released May 19, for instance, found that the average ACA plan deductible saw the steepest increase in history — growing by 37%, or over $1,000, from $2,759 in 2025 to $3,786 in 2026 as enhanced premium tax credits expired.

Those rising costs pose a political challenge for President Donald Trump and the broader GOP, which has opposed enhanced subsidies to help people purchase Obamacare coverage. Republican lawmakers also passed a spending package last year — enacted as the One Big Beautiful Bill Act — that included provisions expected to reduce ACA enrollment and was cited among factors fueling higher premiums this year.
