Enrollment Drop in ACA Coverage Due to Expiring Subsidies

Recent state enrollment data indicate a more significant loss of Affordable Care Act (ACA) coverage than expected, as Congress has not renewed enhanced subsidies. A Georgetown University analysis, leveraging data from states like Arkansas, Colorado, Maryland, Massachusetts, New Mexico, and New York, reveals a trend where many have canceled their insurance plans or failed to pay premiums for 2026.

Despite federal data on initial sign-ups during open enrollment, which includes automatic renewals from late 2025, enrollment figures decreased by 1.2 million participants in 2026, marking a 5% decline from the previous year—the largest annual drop since the marketplaces began in 2014. Researchers Stacey Pogue and Sabrina Corlette emphasize that initial sign-up numbers offer a partial view, underscoring the importance of post-enrollment behavior when receiving the first premium bill.

Analysts predict an overall reduction in marketplace enrollment by around 5 million in 2026, with potential further declines in 2027 due to policies from the One Big Beautiful Bill Act and upcoming regulatory changes. The expiration of enhanced premium subsidies has notably impacted middle-income enrollees, leading to increased plan cancellations. While state exchanges report a 24% rise in cancellations compared to March 2025, lower-income enrollees protected by state-funded subsidies are less likely to lose coverage.
