A perfect storm of rising health care costs, expensive new drugs, and the scheduled end of enhanced federal subsidies could drive Obamacare’s Affordable Care Act (ACA) Marketplace premiums to their steepest levels in years—and hit more than 24 million Americans in their wallets.
According to a new analysis of insurers’ 2026 filings by Peterson-KFF’s Health System Tracker, the median proposed premium hike across 312 marketplace insurers is 18%. Most increases range from 12% to 27%, with more than 125 insurers seeking hikes of 20% or more—the sharpest climb since 2018. Final rates will be locked in by late summer 2025.
