Sharp Decline in ACA Marketplace Enrollment in 2026
6/30/2026, 12:35:50 AM
The Enrollment Drop
19.2 million were enrolled in February 2026, down from 22.1 million a year earlier—a 13% decline of roughly 3 million people; some outlets count the loss as 4 million (The Hill) or 5 million (NPR). HHS attributes part of the decline to a crackdown on improper enrollments.
Policy Context
Enhanced premium tax credits, added in 2021 to expand eligibility and provide $0 premiums, expired on Dec 31 2025 after Congress failed to act; the House passed a three-year extension, but the Senate has not acted. The 2025 Marketplace Integrity and Affordability Rule tightened eligibility and targeted phantom or income-misstated enrollments.
Data & Statistics
Average premiums rose 58% from $113 to $178, and one in ten enrollees missed payments at the start of 2026 (KFF; Wakely Consulting). Improper or phantom enrollments peaked at 5.6 million in 2025; HHS estimates 2.6 million remain, including over 1 million without a Social Security number. ACA members use emergency rooms at nearly twice the rate of employer-insured peers, adding cost pressure.
Official Statements
HHS says the decline reflects a “broad effort to remove improper, phantom, and fraudulent enrollments,” while Trump administration claims it has prevented about 2.9 million ineligible subsidies; CMS tightened eligibility and ended a special enrollment period, and the House approved a three-year credit extension that the Senate has not acted on.
Criticism
KFF analysts Emma Wager and Cynthia Cox argue that rising premiums after the subsidy expiration are the main driver of the enrollment drop, noting that data cannot isolate the share due to fraud versus voluntary disenrollment, and stressing that “real people lost their health insurance or are now paying more.” Insurers cite higher utilization, especially emergency-room visits, as a cost driver.
Conflicts
Enrollment loss is reported as 3 million (AP), 4 million (The Hill), or 5 million (NPR), reflecting differing counting methods. No definitive split exists between fraud-related removals and cost-driven disenrollments, and enforcement impacts remain uncertain.
Verbatim Quotes
- “Given the data that we have, it's really not possible to determine how much of the drop in enrollment is related to fraud versus people voluntarily dropping coverage.” — Emma Wager, senior policy analyst, KFF
- “Real people lost their health insurance or are now paying more.” — Cynthia Cox, senior vice president, KFF
- “9 million people from receiving subsidies for which they didn’t quality.” — Trump administration spokesperson
- “The department said the 13% decline reflected, in part, a broad effort to remove improper, phantom, and fraudulent enrollments from the marketplace.” — Department of Health and Human Services (HHS)
What's Next
KFF projects enrollment could fall to ~17.5 million by year-end 2026 if premiums keep rising; congressional negotiations on extending enhanced subsidies remain pending, and Senate action will decide whether relief returns. Ongoing litigation over the Marketplace Integrity and Affordability Rule may reshape enforcement and future enrollment.
