Affordable Care Act Enrollment Surges, Subsidy Expiration Looms

The enrollment figures for the Affordable Care Act (ACA) show a modest increase for 2026, with nearly 5.8 million Americans signing up by day 29 of the current enrollment period. This marks an increase of approximately 400,000 enrollments compared to the same time last year. However, this increase occurs against the backdrop of looming challenges as subsidies set to expire at the end of 2025 are expected to raise costs for many participants.

Initial data released by the Center for Medicare and Medicaid Services suggests that the climb in enrollment defies expectations that many individuals would drop out due to the anticipated price hikes. Yet, experts caution that the current figures may not accurately reflect total enrollment, which could decline as the open enrollment period progresses. “Overall, it’s just too early to know what any of this means,” stated Jason Levitis, a senior fellow in health policy at the Urban Institute.

As of now, the enrollment window, which began on November 1 and runs until December 15 for coverage starting January 1, is still open. Those looking for coverage to begin later can continue to enroll until January 15. This year’s numbers are approximately 1.5 million lower than the 7.3 million individuals who had signed up by the same point two years ago, indicating annual fluctuations in enrollment trends.

The ACA has experienced significant changes since its inception. Five years ago, around 12 million people selected plans under the ACA. Following the introduction of enhanced tax credits, enrollment numbers doubled to over 24 million four years later. Currently, millions benefit from these subsidies, which health care research non-profit KFF reports will more than double the average annual premiums for those relying on them if they expire as anticipated.

The ongoing debate in Congress regarding the extension of these tax credits has intensified. Democrats are advocating for their continuation, while a vote in the Senate is expected this week on a proposal to extend the subsidies without major changes. However, Republicans have already expressed opposition, diminishing the likelihood of an extension.

Several factors may explain the current uptick in enrollment numbers. The ACA has been a prominent topic in news coverage amid discussions in Congress, potentially increasing awareness among potential enrollees. Additionally, older and sicker individuals often enroll earlier, knowing they require coverage regardless of cost. Those uncertain about their options might be waiting to see if Congress will intervene at the last moment to extend the subsidies.

Levitis pointed out that some individuals may be switching from higher-tier plans to more affordable options with higher deductibles, leading to a delay in the impact of subsidy expiration on enrollment rates. “All of this stuff takes a while to diffuse through the system,” he noted.

From a political perspective, Joe Antos, a health economist at the American Enterprise Institute, suggested that Republicans might attempt to leverage the latest enrollment data as evidence that the expiration of subsidies will not hinder access to affordable coverage. Nonetheless, he acknowledged that politicians in vulnerable districts, particularly in red states, may face backlash from constituents if the subsidies are not extended.

As the open enrollment period continues, the future of the Affordable Care Act remains entwined with the ongoing political negotiations surrounding health care subsidies. The next few weeks will be critical in determining how many Americans will secure health coverage for the coming year and at what cost.
