Average monthly premiums for Affordable Care Act marketplace enrollees climbed 58% to $178 in 2026, up from $113 the prior year. This sharp increase followed the expiration of enhanced federal premium tax credits at the end of 2025.
Why it matters
The lapse in federal subsidies has triggered a 37% surge in average deductibles to $3,786 and a 11.43% decline in exchange enrollment during the first quarter of 2026. These rising costs represent a significant burden on overhead and worker retention for businesses relying on these plans.
Average monthly premiums rose to $178 from $113, representing a 58% increase for marketplace enrollees. Enrollment in ACA exchanges dropped 11.43% in the first quarter of 2026 as total national health spending reached a projected $6.0 trillion.
The players
The White House
The executive branch of the U.S. government tasked with setting national health policy and directing federal subsidy programs.
Congressman Westerman
A member of the U.S. House of Representatives who introduced legislative proposals to reform federal healthcare coverage.
The details
The cost spike occurred after the legislative expiration of enhanced tax credits that had previously capped out-of-pocket insurance payments. To mitigate the resulting coverage gap, the federal government initiated a program redirecting funds from insurers into cost-sharing mechanisms for remaining enrollees. Employers must now contend with higher premium floors and record-high average deductibles of $3,786 when budgeting for employee benefits.
