The law stayed. The affordability boost did not.
The Affordable Care Act itself did not expire. What ended was the temporary expansion of Marketplace premium tax credits created during the pandemic and later extended through 2025. HealthCare.gov now states that the additional savings ended on December 31, 2025.
The marketplaces still exist, but the payment formula got less generous. For many households, the 2026 system is the same law with worse math.
2026 pulled the market back toward the old affordability cliff
CMS' 2025 program-integrity materials say the Marketplace reverted in 2026 to the old premium-tax-credit framework. Consumers above 400 percent of the federal poverty level are no longer eligible for advance premium tax credits, and many consumers below that line still receive less help than they did in 2025.
The official CMS examples show how sharp that change can be. A consumer named Anton who paid $0 in 2025 for a silver plan at about 146 percent of poverty would pay $51 a month in 2026 if plan pricing stayed the same. Another example shows a consumer just above 400 percent of poverty losing premium-tax-credit eligibility altogether.
The official premium math got visibly worse
CMS says the average HealthCare.gov premium after tax credits for the lowest-cost plan in 2026 is projected to be $50 a month for eligible enrollees, up $13 from 2025. For a 50-year-old earning twice the poverty level, CMS says tax credits cover 81 percent of the benchmark premium in 2026, down from 93 percent in 2025.
The low-cost-plan access story got worse too. CMS says nearly 60 percent of eligible re-enrollees in 2026 will have access to a plan in their chosen category at or below $50 after tax credits. In 2025, that figure was 83 percent.
Coverage does not disappear in one day. The squeeze shows up first.
The Congressional Budget Office estimated that if the enhanced premium tax credits were not extended, the number of people without insurance would rise by 2.2 million in 2026 and gross benchmark Marketplace premiums would rise by 4.3 percent on average. CBO also said the uninsured increase would average 3.8 million a year over 2026 through 2034 under a permanent expiration scenario.
CMS says 23.1 million consumers still selected or were automatically re-enrolled in coverage for 2026. CBO explicitly says the first-year uninsured increase is smaller partly because automatic renewal delays the full consumer response to the subsidy loss.
The timing landed on households that were already making trade-offs
West Health and Gallup reported in March 2026 that about one in three U.S. Adults, more than 82 million people, made at least one daily-life trade-off to afford healthcare. Among uninsured adults, 62 percent reported making at least one sacrifice. The survey highlighted borrowing money, prescription rationing, and pressure on basic household bills.
The Gallup-West Health survey measures healthcare cost pressure broadly, not Marketplace premiums alone. It still describes the environment into which the 2026 premium changes landed: millions of Americans were already choosing between medical costs and the rest of life.
