Significant Decline in ACA Enrollment Linked to Expired Subsidies

Recent state reports reveal a more pronounced decline in Affordable Care Act (ACA) enrollments than anticipated. This downturn is linked to Congress's decision not to renew enhanced subsidies, significantly impacting coverage retention rates. Data from Arkansas, Colorado, Maryland, Massachusetts, New Mexico, and New York indicate high numbers of cancellations or non-payment after initial sign-up for 2026 coverage, according to a Georgetown University analysis.

Federal authorities have reported the number of initial enrollments during the open enrollment period, including those automatically renewed at the close of 2025. Notably, the 2026 open enrollment period saw a 5 percent decrease in sign-ups—a 1.2 million drop from the previous year—marking the largest decline since the marketplaces launched in 2014.

Researchers Stacey Pogue and Sabrina Corlette stress the importance of examining consumer behavior post-premium billing to fully understand enrollment trends. Projections suggest a total reduction of about 5 million enrollees in the 2026 marketplace, with further decreases expected in 2027, as legislative changes and potential regulatory updates under the Trump administration take effect.

The expiration of enhanced premium subsidies has significantly affected enrollees, influencing November's election topics. Initial figures from several state exchanges report a 24 percent increase in plan cancellations over March 2025 figures. Middle-income individuals, who saw reduced financial support from expired premium tax credits, were predominantly among those canceling coverage.

Economically disadvantaged enrollees were largely protected from rising rates through state-supported subsidies, with this group showing less propensity to terminate coverage. For example, Maryland experienced a 13 percent decline from January to April, exceeding the 3 percent fall of the prior year. Arkansas saw a 16 percent reduction, and Massachusetts noted a 14 percent decrease—more than double the figures from 2025, while New Mexico observed over an 8 percent drop.
