Imagine a scenario where millions of Americans lose their health insurance, causing a ripple effect that drives up costs for everyone else. This isn’t a dystopian fantasy—it’s a potential reality as enhanced premium subsidies under the Affordable Care Act (ACA) expire, leaving many to wonder: Can the system survive this blow? But here’s where it gets controversial: while some experts warn of a looming 'death spiral,' others argue the concerns are overblown. Let’s dive into the details and explore why this issue is far from black and white.
On September 30, 2025, demonstrators gathered outside the U.S. Capitol in Washington, D.C., rallying for healthcare funding. Their urgency was palpable, as millions now face a difficult choice: keep their ACA coverage or drop it due to skyrocketing premiums. According to a CNBC report, the expiration of enhanced subsidies has already caused premiums to more than double for the average recipient, jumping from $888 in 2025 to $1,904 in 2026, as estimated by the nonpartisan health policy research group KFF. And this is the part most people miss: it’s not just about higher costs—it’s about who’s leaving the system and what that means for everyone else.
Young, relatively healthy individuals are the most likely to opt out, deeming the premiums too high for coverage they may rarely use. Economists warn that this exodus could leave behind an older, sicker population of enrollees, who are more likely to require costly care. This shift could force insurers to raise premiums even further, creating a self-reinforcing cycle. Meredith Rosenthal, chair of the Department of Health Policy and Management at Harvard University's T.H. Chan School of Public Health, explains, 'If these younger, healthier individuals exit the risk pool, the average cost of care will rise, pushing premiums higher and potentially triggering a death spiral.'
The numbers are staggering. In 2025, about 22 million Americans benefited from enhanced premium subsidies. Now, the Urban Institute and The Commonwealth Fund estimate that 7.3 million people will leave the ACA marketplace in 2026, with 5 million of them becoming uninsured. Young adults, particularly those aged 19 to 34, account for nearly half of this anticipated increase in uninsured individuals. Jessica Banthin, a senior fellow at the Urban Institute, notes that while 2.3 million young people are expected to lose coverage, only about 500,000 uninsured individuals will be aged 55 to 64. Here’s the kicker: this demographic shift could destabilize the entire system.
Insurers have already raised gross premiums by an estimated 26% for 2026, according to KFF. Emma Wager, a senior ACA policy analyst at KFF, explains that 4 percentage points of this increase are directly tied to expectations that healthier individuals will drop coverage. The remaining increase is attributed to other factors, such as the rising cost of specialty drugs, labor, and consolidation among medical providers. But as premiums climb, the question remains: Who will be left to pay the bill?
Now, for the controversial counterpoint: some policy experts argue that fears of a death spiral are premature. Michael Gusmano, a professor of health policy at Lehigh University, suggests that while the loss of enrollees will likely lead to higher prices, the current structure of premium tax credits may prevent a full-blown crisis. These credits cap out-of-pocket expenses as a percentage of household income, meaning that if premiums rise, the federal government—not consumers—bears much of the cost. John Graves, a professor at Vanderbilt University, adds that while enrollment may drop, the system could still maintain 'stable risk pools' thanks to these income caps.
However, not everyone is convinced. Gerard Anderson, a professor at the Johns Hopkins Bloomberg School of Public Health, warns, 'The more money you take away from subsidies, the greater the prospect of a death spiral.' And here’s where it gets even more contentious: some Republican lawmakers and former President Donald Trump have proposed converting the current subsidy structure into a fixed-dollar payment. If implemented, this change would shift the burden of premium increases entirely onto individuals, potentially accelerating the very death spiral experts fear.
So, what’s the bottom line? The expiration of enhanced ACA subsidies has set the stage for a high-stakes battle over the future of healthcare in America. Will the system weather the storm, or will it spiral into chaos? Here’s a thought-provoking question for you: Is the current subsidy structure enough to prevent a death spiral, or are we simply delaying the inevitable?
