At the heart of what is now the longest U.S. government shutdown in history are federal subsidies that millions of Americans use to purchase health insurance on government-run marketplaces.

The shutdown began as Democrats dug in their heels to prevent these subsidies from expiring. And now, members of Congress are facing increasing pressure to end the shutdown 鈥� not just because of its effects on airports and federal programs like nutrition assistance, but also because of public concerns about rising insurance premiums.

These subsidies were greatly expanded in 2021 by Democrats who controlled Congress at the time. This led to a surge in enrollment on these marketplaces, which were created in 2010 under the Affordable Care Act (ACA), also known as Obamacare.

The expanded subsidies are set to expire next month,聽 who buy health insurance on Obamacare exchanges. For weeks, Democrats have called on Republicans to agree to extend the subsidies as a condition of reopening the government. Republicans have criticized the subsidies as wasteful and open to abuse, while arguing that the government must reopen first before Congress can discuss health insurance.

Open enrollment in marketplaces for 2026 plans began Nov. 1. , reflecting uncertainty over what will happen to the expanded subsidies. The majority of enrollees receive some level of support designed to make Obamacare more affordable and increase the insured pool. The overall cost of insurance has been rising, in large part because聽.

Dawn Schmidt doesn鈥檛 know yet how much her premiums will rise next year, but she鈥檚 worried about being able to afford her insurance plan. She retired from her job at Boeing in 2020 and lives in Pennsylvania, which administers its own ACA marketplace, known as Pennie. Administrators have warned her that premiums could rise by 82%. 鈥淚t鈥檚 a lot. It adds up,鈥� she says.

What are the expanded subsidies, and why are they expiring?

Subsidies were baked into Obamacare from the start. The idea was to assist individuals who didn鈥檛 have either employee-provided plans or access to Medicaid or Medicare, but couldn鈥檛 afford the market price of private insurance. Those with low incomes were required to pay between 2% and 10% of their income, with the government paying the rest.

The expanded subsidies were introduced by Democrats in 2021 during the COVID-19 pandemic, when access to health care was a pressing concern. Financial support was extended to Americans making more than four times the federal poverty level, now above $60,000 for an individual enrollee, while those with the lowest incomes no longer had to pay any premiums. Enrollment more than doubled,聽

鈥淲e have more people in the system than we鈥檝e ever had before, and that鈥檚 a good thing,鈥� says Elena Marks, a health policy expert at Rice University鈥檚 Baker Institute for Public Policy. But, she adds, 鈥渢he underlying costs continue to escalate ... which is a bad thing.鈥�

To pass the legislation, Democrats had to set an expiration date to satisfy congressional fiscal rules. This created an enrollment cliff that was already causing concern before the impasse on government spending that led to the Oct. 1 shutdown.

Republican Rep. Mike Lawler (right) confronts House Minority Leader (and fellow New Yorker) Hakeem Jeffries about signing on to a bill that would extend Affordable Care Act tax credits, in the Capitol Visitor Center, Oct. 8, 2025.

How are Democrats and Republicans responding?

Democrats have tried to use the enrollment cliff as leverage to force an extension. Citing higher premiums in New York, Sen. Chuck Schumer has accused Republicans of ignoring a 鈥渉ealthcare crisis鈥� that could see millions lose coverage if subsidies are slashed. 鈥淭hese devastating price hikes are entirely avoidable, but if Republicans keep stick[ing] their heads in the sand, New York families will be paying the price,鈥� .

Most Republicans take a different view. They point to the fiscal burden of extending subsidies that, if made permanent, , according to estimates from the Congressional Budget Office. They question the design of Obamacare and its failure to curb rising health care costs, as well as the risk of waste and fraud. Some want to scrap the Affordable Care Act and replace it with an alternative approach.

But a redo of Obamacare is politically fraught. A GOP-led effort to repeal it in 2017 failed to pass the Senate amid infighting over what exactly would replace it. , given that open enrollment for 2026 is already underway. Rep. Mike Lawler, a Republican who represents a swing district in New York, 聽to extend the credits for one year.

聽and that cutting them could sour voters on Republicans. A poll taken in September by KFF Health, a nonprofit research group, found that 3 in 4 respondents want the subsidies extended. In July, Tony Fabrizio, a pollster who has worked on campaigns for President Donald Trump, and that their expiration could penalize Republicans in competitive districts in the 2026 midterms. GOP-run states such as Georgia and Florida have seen in recent years.

What are the possible consequences of cutting subsidies for Obamacare?

Higher premiums could deter millions of Americans from enrolling in the 2026 program, which means more uninsured people. Those with middle incomes who didn鈥檛 benefit from the original subsidy program may decide to pay more out of pocket. Experts say far greater attrition is likely among low-income groups whose costs were almost entirely subsidized.

While critics have questioned who took early retirement, such individuals are in the minority. had incomes over four times the federal poverty rate and, as a result, were eligible for the expanded subsidies. Of these, around half were between the ages of 50 and 64.

Ms. Schmidt falls into this category: She retired early because her husband is older, and they wanted to make the most of their retirement. He is now on Medicare, while she is too young to qualify and buys Obamacare insurance. She paid $211 a month this year for her plan, which has a $6,000 deductible, and is bracing to pay more if subsidies are eliminated.

鈥淲e鈥檙e probably going to have to cut back on things like vacations. We already cut back on spending on our grandchildren for Christmas and birthdays,鈥� she says.

The participation of early retirees in Obamacare was woven into its design, says Ms. Marks at Rice. 鈥淧art of the reason behind the ACA marketplace was to allow people to not stay in jobs they didn鈥檛 want to stay in, to get health insurance,鈥� she says.

Still, they aren鈥檛 the main beneficiaries of federal aid, she adds. 鈥淢ost of the subsidy dollars go to the lowest-income people.鈥�

Even with subsidies, the rising cost of premiums puts a strain on pocketbooks. Young people are generally more likely to forgo health insurance and risk having to pay out of pocket for medical care. This creates a quandary for insurers and regulators, since young people tend to use less health care compared with older people; insurance pools rely on serving a demographic mix.

This has long been the challenge hanging over Obamacare: If not enough young people pay into the system and the resulting pool skews less healthy, . The individual mandate to buy health insurance was supposed to tackle this problem. Congress deactivated it during Mr. Trump鈥檚 first term.

Behind this difficulty lies a stark reality: Americans pay far more for health care than other countries, and most of聽 have been rescinded or have stalled. Tens of millions are still uninsured. And, while policy experts have proposed various solutions, so far neither political party has been willing to significantly cut rising expenditures on health insurance programs for an aging population.
