5 Million Americans Drop ACA Health Coverage in 2026 After Premium Subsidies Expire

A far larger number of Americans than previously known have dropped Affordable Care Act (ACA) health insurance for 2026, according to federal data released on June 26, 2026. The figures reveal that five million fewer people are currently enrolled in ACA marketplace plans compared to the record high reached last year — a dramatic contraction in one of the cornerstone programs of the US individual health insurance market.

The data, covering the 29 states that use the federal Healthcare.gov marketplace, breaks the decline into two components: more than 1 million fewer people selected a plan for 2026 during open enrollment, and a further 4 million either actively disenrolled or failed to pay their premiums and consequently lost coverage. The primary cause is straightforward economics. Premium costs in the ACA marketplaces roughly doubled on average from 2025 to 2026 after the enhanced premium tax credits — extra federal financial assistance that had kept plans affordable — were allowed to expire. Democrats had attempted to negotiate an extension of the credits during a government shutdown in October 2025, but the effort failed.

Health policy researchers point to affordability, not fraud, as the dominant driver. As one researcher from KFF noted, when costs rose sharply, many enrollees simply could no longer afford the monthly premiums and dropped their plans. A senior research fellow at the Georgetown Center on Health Insurance Reforms agreed, stating there is no evidence that a five-million-person drop could be explained by fraud allegations.

The contraction is also a problem for insurers. Several health insurance companies, including Cigna, have announced they will not participate in ACA markets next year. Fewer customers make the markets less appealing to carriers — particularly because the people dropping coverage tend to be healthier individuals. If too many healthy enrollees exit, markets risk entering a so-called 'death spiral,' though analysts say no region is currently at that point. Concerningly, early insurance rate filings for 2027 show that premiums are set to rise again next year, suggesting enrollment may continue to shrink and putting further pressure on consumers navigating high healthcare costs.
