Why did 3 million people lose their ACA health insurance in 2026?
Nearly 3 million people dropped off ACA Marketplace coverage in 2026 — from 22.1 million in February 2025 to 19.2 million in February 2026, the first decline in seven years, according to new CMS effectuated-enrollment data analyzed by KFF and HHS. Two things happened at once. The enhanced premium tax credits expired on December 31, 2025, and the average premium payment after subsidies jumped 58% for people who re-enrolled — while the share of sign-ups who actually kept paying for coverage fell from 90% to 83%. The Trump administration says much of the drop was deliberate fraud cleanup: HHS's ASPE office states, verified verbatim, "By our estimate, improper, phantom and fraudulent enrollment peaked at 5.6 million people in 2025," and reports its program-integrity efforts stopped or ended subsidies for about 2.9 million people it says did not qualify. Independent analysts counter that the losses tracked affordability: every state except New Mexico (up 14%) lost enrollment, with Ohio and Oklahoma down about 32%, Arizona down 30%, and South Carolina down 29%. As Cynthia Cox, Senior Vice President, KFF, put it on the record before the KFF Quick Takes analysis: 'ACA Marketplace Enrollment Is Down By 3 Million After Big Jump in Premium Payments' (2026-06-29): “While the Trump administration attributes this drop in enrollment to their attempts to address fraud, this coverage loss happened at the same time millions of people faced steep increases in their premium payments — often in the double or even triple digits — with the expiration of enhanced tax credits.” For help choosing or enrolling in a plan, call United Enrollment Services, a licensed insurance agency, at 1-866-401-4116.

Editor's note: Enrollment figures are February point-in-time snapshots (CMS effectuated data); KFF's state analysis uses a 21.8M 2025 baseline while ASPE reports 22.1M — both show a ~12-13% decline to 19.2M. The administration's fraud-removal estimates (ASPE) and independent analysts' affordability explanation are presented side by side; no official attribution split exists. Will update when mid-year 2026 effectuation data and final 2027 rates publish.
What it means
- The 'effectuation rate' — people who not only picked a plan but actually paid for it — fell from 90% to 83%, meaning many 2026 sign-ups never kept coverage once the first bills arrived.
- Both explanations are partly true, and no official breakdown separates them: Washington has not published how much of the decline came from expired subsidies versus removed improper enrollments.
- KFF projects enrollment could slide toward roughly 17.5 million by the end of 2026 as more people drop coverage mid-year.
- Insurers' preliminary 2027 filings propose another round of double-digit premium increases (median 14% across early filings), so the affordability squeeze is not over.
- Current update (August 1, 2026): CMS has released effectuated-enrollment data only through February 2026. We will update this page when mid-year figures and final 2027 premium rates are published this fall.
Action steps
- If you dropped your plan over cost, you may still qualify for the standard premium tax credit — it did not disappear; run your income through HealthCare.gov's plan preview before assuming coverage is unaffordable.
- Losing other coverage, moving, or an income change can open a Special Enrollment Period — check HealthCare.gov's screener rather than waiting for November.
- If your subsidy was ended over an eligibility or paperwork flag you believe is wrong, call the Marketplace Call Center (1-800-318-2596) and appeal — removals can be contested.
- Mark November 1, 2026: open enrollment for 2027 plans, when this year's proposed double-digit rate increases become final prices you can compare.
Risks & deadlines
- The enhanced subsidies expired December 31, 2025; unless Congress acts, the standard credit pays less and cuts off entirely above 400% of the Federal Poverty Level.
- Preliminary 2027 rate filings show a median 14% proposed increase; final rates land before open enrollment begins November 1, 2026.
- If you were flagged for failing to file and reconcile taxes, a July 2026 federal court ruling means exchanges must stop denying premium tax credits on that basis — verify your account status with the Marketplace.
