Average monthly enrollment in the Affordable Care Act (ACA) Marketplace is projected to decline by nearly 6 million in 2026, falling from 22.3 million in 2025 to approximately 17.5 million, according to estimates based on data from the Wakely Consulting Group and federal Marketplace reports, as reported by livemint.com.
This decline is attributed to the expiration of enhanced federal premium tax credits that had helped subsidize insurance costs for many consumers. The enhanced credits, introduced during the COVID-19 pandemic, made ACA plans more affordable, boosting enrollment numbers. With these subsidies ending, fewer consumers are expected to maintain active coverage and pay premiums, leading to a significant drop in effectuated enrollment—those who actually pay premiums and keep their coverage active.
The anticipated reduction in ACA enrollment has broad implications for the U.S. health insurance market. Lower enrollment could increase the average risk pool's cost, potentially driving up premiums for remaining enrollees. This shift may also affect insurers' strategies and the overall accessibility of affordable health insurance for millions of Americans. The change underscores the critical role of federal subsidies in sustaining participation in the ACA Marketplace, especially for lower-income populations.
Looking ahead, stakeholders will closely monitor enrollment trends throughout 2026 to assess the full impact of subsidy expirations. Policymakers and health advocates may consider new measures to address coverage gaps and affordability challenges. The enrollment figures released later this year will provide further insight into how consumers respond to the changing subsidy landscape and what adjustments might be necessary to stabilize the ACA Marketplace.
