Millions of Americans may soon lose their health insurance, potentially leading to a significant rise in costs for those who remain covered. This scenario is a direct consequence of the expiration of enhanced premium subsidies for individuals purchasing coverage through the Affordable Care Act (ACA) marketplace. As a result, insurance premiums are expected to skyrocket, causing a potential "death spiral" in the ACA market.
The loss of these subsidies has already led to a substantial increase in premiums, with the average subsidy recipient facing a more than double premium, rising from $888 to $1,904 per month in 2026. Economists predict that young, healthy individuals are most likely to drop their policies if they deem the premiums too high. This would leave an older, sicker population, who are more likely to require costly medical care, potentially prompting insurers to further raise premiums to cover the increased costs.
Meredith Rosenthal, chair of the Department of Health Policy and Management at Harvard University's T.H. Chan School of Public Health, warns that this process could spiral out of control, leading to more disenrollment and even higher premiums. The situation is particularly concerning for young adults, as an estimated 7.3 million people are expected to leave the ACA marketplace in 2026, with about 5 million becoming uninsured. This includes nearly 2.3 million young adults aged 19 to 34, who account for nearly half of the anticipated increase in the number of uninsured.
However, some policy experts argue that the warnings of a death spiral are premature. They suggest that the disappearance of enhanced subsidies is a one-time shock and that the tax credit structure, which caps out-of-pocket expenses for insurance premiums, should prevent a full-blown death spiral. The standard premium tax credits, which have been in place since 2014, remain in effect, capping out-of-pocket premiums at around 10% of annual income for qualifying consumers.
The real concern lies in the potential conversion of the subsidy structure into a fixed-dollar payment for consumers, a proposal by Republican lawmakers and former President Donald Trump. In this scenario, the entire premium increase would be borne by individuals, significantly increasing the risk of a death spiral. Gerard Anderson, a professor of health policy and management, emphasizes that the more money taken away from subsidies, the greater the prospect of a death spiral.
Ultimately, the future of the ACA marketplace hinges on the decisions made regarding the subsidy structure. As the situation unfolds, the public will have a clearer understanding of the impact on enrollment and the demographics of those who drop their coverage.
