Significant Decline in ACA Marketplace Enrollment Following Subsidy Expiration
Nearly 5 million individuals in the United States lost their health insurance coverage via the Affordable Care Act (ACA) Marketplace this year following the expiration of enhanced federal subsidies. New federal data reveals that elevated premiums have led numerous consumers to discontinue or avoid renewing their coverage.
With over 1 million fewer enrollees in Marketplace plans for 2026 compared to the previous year, a total enrollment decrease from 24.2 million in 2025 to 19.2 million has been observed. These enhanced subsidies, initially introduced during the COVID-19 pandemic and later extended, significantly lowered monthly premiums but were allowed to expire at the end of 2025. This lapse resulted in considerable increases in monthly costs for many consumers.
According to health policy researchers, many individuals opted for less costly plans. Nevertheless, those maintaining the same plans typically experienced premium increases exceeding 100% post-subsidy expiration. "We know that real people lost their health insurance coverage," stated Cynthia Cox, vice president and director of the Affordable Care Act program at KFF, as the coverage loss coincided with substantial premium rises.
The impact of the subsidy expiration is notably significant in Kansas, where Medicaid has not been expanded under the ACA. Consequently, many lower-income residents who lose Marketplace coverage have limited alternatives for affordable health insurance. Data from the Kansas Health Institute highlights a 28.9% increase in the average premium for a benchmark Silver plan for a Kansas family of four in 2026, marking the largest rise since 2019, driven solely by insurance premium escalations.
A surprising aspect of the enrollment data is the demographic distribution affected by the decrease. Almost half of the disenrollment from Marketplace plans was among households earning above 400% of the federal poverty level. This group had previously benefited from enhanced subsidies, which were no longer available, leading to a significant portion of the overall enrollment decline.
The new data has reignited discussions about the causes behind the sharp drop in Marketplace enrollment. While some attribute the enrollment decrease solely to the expiration of subsidies and resultant premium hikes, others point to the previous administration's efforts in addressing fraudulent and ineligible enrollments, suggesting both factors have likely played a role. Experts emphasize the timing of these declines coinciding with substantial premium increases post-subsidy, rendering coverage unaffordable for numerous households.
