A new analysis of initial rate filings for Affordable Care Act (ACA) Marketplace plans submitted by 312 insurers in all 50 states and the District of Columbia finds the median proposed increase for 2026 is 18%, more than double last year’s 7% median proposed increase. The proposed rates are preliminary and could change before being finalized in late summer. In addition to rising cost and utilization of services, insurers cited the expiration of enhanced premium tax credits as a significant factor in their rate hikes for next year.
