The expiration of enhanced Affordable Care Act (ACA) subsidies at the close of 2023 isn’t simply a policy shift; it’s a revealing stress test of the American healthcare system, exposing a fundamental tension between intended access and actual affordability. While headlines report on premium spikes – and indeed, costs have doubled for many – the deeper story lies in the behavioral changes now rippling through the marketplace, and what those changes signal about the limits of a system reliant on subsidies to function equitably. The situation isn’t merely about higher bills; it’s about individuals actively rationing care, foregoing necessary medications, and ultimately, disconnecting from coverage altogether.
The immediate impact is starkly illustrated by the experiences of individuals like CJ Richey, a 60-year-old self-employed counselor in Colorado. Her monthly premium surged from $265 to $903, a nearly 240% increase, rendering the insurance unsustainable. This isn’t an isolated case. Natalie Richards, a 37-year-old single mother in Texas, saw her premium jump from $3 to $164, anticipating eventual cancellation due to inability to pay. These aren’t abstract statistics; they are portraits of individuals facing impossible choices. Between early 2025 and 2026, over 1 million Americans canceled their marketplace plans, a figure that, while significant, likely underestimates the full extent of disenrollment as people delay dropping coverage while searching for alternatives. The average enrollee, according to KFF, saw monthly costs more than double in January 2026.
The core of the problem stems from the sunsetting of enhanced ACA subsidies, credits designed to lower costs for lower- and middle-income households. These subsidies, initially expanded in 2021, effectively masked the underlying cost of insurance for many. With their expiration, the true price of marketplace plans has become painfully apparent, particularly for those who don’t qualify for Medicaid and lack employer-sponsored insurance – a demographic encompassing a substantial portion of the gig economy and self-employed workforce. The subsidies previously covered families up to 400% of the federal poverty line ($128,000 for a family of four), and their removal has created a coverage gap, leaving many in a precarious position.
This isn’t simply a matter of individual hardship; it’s a destabilizing force within the marketplace itself. Sara Rosenbaum, a professor emeritus of health law and policy at George Washington University, describes the situation as a “death spiral,” arguing that affordability is the linchpin of a functioning system. Rosenbaum highlights the vulnerability of older Americans under 65 and those with incomes slightly above Medicaid eligibility, populations now at risk of falling through the healthcare safety net. The concern is that as healthier individuals opt out due to cost, the risk pool shrinks, driving up premiums for those who remain, further exacerbating the problem. This dynamic, known as adverse selection, threatens to unravel the gains made in coverage rates since the ACA’s inception.

It’s crucial to understand that the 1.4 million enrollment dip observed in January 2026 is likely just the beginning. A nonscientific survey conducted by Business Insider revealed that many enrollees are seriously considering dropping coverage, and some have no other option. The broader context of rising healthcare costs – premiums and care costs are increasing for those with employer-sponsored and private coverage as well – underscores the systemic nature of the problem. A January 2026 KFF poll identified healthcare costs as a top financial stressor for Americans, surpassing even housing and groceries. The ACA marketplace, while intended as a safety net, is proving to be a remarkably “fragile market,” susceptible to policy shifts and economic pressures.
Looking ahead, the immediate research priority should be a granular analysis of disenrollment patterns. Beyond simply tracking the number of people losing coverage, researchers need to understand who is dropping plans, why, and what alternative arrangements – if any – they are making. Are individuals relying on emergency room care? Are they delaying preventative services? Are they simply going without? This data is essential for accurately assessing the public health consequences of the subsidy expiration. Furthermore, studies are needed to evaluate the effectiveness of state-level interventions aimed at mitigating the impact of the federal policy change. The question isn’t just whether Congress will reinstate the subsidies, but whether a more sustainable, long-term solution can be found to ensure affordable access to healthcare for all Americans – and whether the current marketplace model is even capable of delivering that. We should be watching closely to see if enrollment trends reverse as the next open enrollment period approaches, and whether states with more robust safety nets experience less dramatic declines in coverage.
