5 Million Americans Lose ACA Coverage as Premium Costs Surge Under Republican Policy

ACA Enrollment Drops by 5 Million as Premium Costs Spiral Out of Reach

A significant decline in Affordable Care Act marketplace enrollment has been confirmed by newly released federal data, revealing that 5 million fewer Americans currently hold ACA health coverage compared to last year's record-breaking figures. Health policy analysts point squarely at skyrocketing premium costs as the driving force behind this dramatic exodus from the marketplace.

The Numbers Tell a Stark Story

According to a report published Friday by the Department of Health and Human Services, current ACA marketplace enrollment stands at 19.2 million people. That figure represents a sharp retreat from the 24.2 million enrollees recorded in 2025, which had been the highest number in the program's history.

The decline breaks down into two distinct components. More than 1 million fewer individuals selected a plan for 2026 during the open enrollment period. Beyond that, an additional 4 million people either voluntarily disenrolled or forfeited their coverage by failing to pay their monthly premiums — a rate of non-payment that far exceeded patterns seen in previous years.

Expired Tax Credits Send Premiums Soaring

The financial backdrop to this enrollment collapse centers on the expiration of enhanced premium tax credits that had made marketplace coverage significantly more affordable during and after the pandemic era. When Republican lawmakers in Congress allowed those credits to lapse, premium costs for many consumers doubled on average from 2025 to 2026, with some enrollees experiencing triple-digit percentage increases in what they owed each month.

Democrats attempted to preserve those subsidies, going so far as to shut down the federal government in October 2025 in a bid to negotiate an extension of the credits. Those efforts ultimately failed, leaving millions of Americans facing dramatically higher insurance bills.

"The main takeaway is that enrollment is down 13% from last year," said Cynthia Cox, director of KFF's Program on the ACA. "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 double or even triple-digit increases in their premium payments with the expiration of enhanced tax credits."

Trump Administration Points to Fraud — Experts Push Back

Officials within the Trump administration have framed the enrollment decline differently, suggesting that a cleanup of fraudulent sign-ups is responsible for the shrinking numbers. This narrative aligns with arguments promoted by the Paragon Health Institute, a conservative think tank with influence in current administration circles.

However, health policy researchers are largely unconvinced by that explanation. They argue that the enrollment surge seen during the pandemic was a straightforward and predictable result of Congress making coverage more affordable through federal investment — not a sign of widespread fraud.

"The marketplace doubled in size during the period when there were enhanced subsidies because the coverage was much more affordable and much more appealing to people," Cox explained.

Stacey Pogue, senior research fellow at the Georgetown Center on Health Insurance Reforms, echoed that view. "I don't see data that point to the conclusion that a 5 million person drop can be explained by allegations of fraud," she said. "There's lots of evidence pointing to people making decisions based on what they can pay each month."

While both researchers acknowledge that fraud exists in insurance markets broadly, neither believes it accounts for anything close to the full scale of this year's enrollment drop.

Financial Strain Forces Hard Choices for American Families

The premium increases are landing on consumers already stretched thin by persistent inflation across the broader economy. As healthcare costs climb, families are being forced into difficult trade-offs — reconsidering household budgets, employment decisions, and other major life choices in light of what they can afford to pay for health coverage.

The ripple effects extend beyond individual households. Several major insurance companies, including Cigna, have announced plans to exit ACA markets in the coming year. Fewer enrolled consumers make the marketplace less commercially attractive to insurers, raising concerns about long-term market sustainability.

Could the ACA Market Enter a Death Spiral?

A particular concern among health economists is the composition of those leaving the marketplace. Evidence suggests that healthier individuals — who tend to use less medical care — are disproportionately dropping coverage. When healthy enrollees leave insurance pools, the remaining customer base skews sicker, which drives costs higher and can trigger a self-reinforcing cycle of rising premiums and further departures known as a "death spiral."

For now, Cox says she is not predicting that outcome. "I think there are still enough people buying ACA marketplace coverage and that's going to keep these markets working," she noted. "At this point, we don't see any parts of the country that are at risk of having no insurance company."

Nevertheless, the trajectory heading into 2027 offers little reassurance. Early insurance rate filings analyzed by Georgetown's Pogue indicate that premiums are set to rise again next year, suggesting that the financial pressure on ACA enrollees is far from over. Unless legislative action intervenes to restore affordability, millions more Americans could find themselves priced out of coverage in the years ahead.
