US insurers face 30% Obamacare premium surge

Premiums on the US federal health insurance marketplace are set to climb sharply next year, with insurers preparing for what could be the most significant adjustment since the Affordable Care Act (ACA) launched in 2014.

Documents reviewed by The Washington Post show that benchmark “silver” plans sold through Healthcare.gov will increase by an average of 30 per cent for 2026. The change affects roughly 17 million Americans who rely on the federal marketplace and marks the steepest rise since 2018, when premiums jumped by 34 per cent.

The new rates, finalized by the Centers for Medicare and Medicaid Services (CMS), land amid a federal government shutdown and a prolonged partisan standoff over whether to extend pandemic-era subsidies. Those temporary supports—first enacted under the American Rescue Plan and later extended by the Inflation Reduction Act—are due to expire at year’s end unless Congress acts.

Democrats have insisted the additional aid is necessary to blunt inflation-driven costs, while Republicans counter that the relief measures were never intended to be permanent. Without an extension, many households could see premiums double or triple in 2026 as federal assistance is withdrawn.

Healthcare.gov will open for window shopping next week, offering consumers their first glimpse of the new rate environment ahead of the November 1 enrollment period.

Policy and Pricing Pressures

The affordability challenge comes at a delicate time for insurers. After several years of relative stability—benchmark premiums declined annually between 2018 and 2022—enrollment has more than doubled since 2020, reaching 24 million this year. But escalating medical inflation, rising drug and hospital costs, and an eroding subsidy structure are expected to add pressure to underwriting margins.

The Congressional Budget Office estimates that a ten-year extension of enhanced subsidies would cost about $350 billion, roughly 50 per cent more than the baseline ACA spending forecast. Insurers have warned that without renewed support, healthier enrollees may exit the market, worsening the risk pool and prompting further rate adjustments.

Idaho’s Early Glimpse of Impact

Idaho, one of the few states to open enrollment early, offers an early snapshot of what’s coming. “On average, gross premiums, or the overall cost of the premium, has gone up about 10 percent. And the net premium, or the amount the consumer pays after the tax credit has been applied, has increased about 75 percent,” said Pat Kelly, executive director of Your Health Idaho, in an interview with The Hill.

Of the state’s 135,000 marketplace enrollees, about 13,000 earn more than 400 per cent of the federal poverty line and will lose eligibility for premium tax credits if Congress does not act. Many of these households will be automatically reenrolled, potentially without realizing the magnitude of the price shift.

Uneven State Outcomes

The effect of the subsidy lapse will vary widely. States that expanded Medicaid—covering residents up to 138 per cent of the poverty line—will see a smaller disruption than non-expansion states such as Mississippi, Tennessee, and South Carolina. The Urban Institute forecasts sharp uninsured rate increases in those jurisdictions if the credits expire. KFF data suggest that congressional districts in Wyoming, West Virginia, Connecticut, and Illinois could experience premium hikes ranging from 535 to 700 per cent.

“There’s been about a dozen state-based marketplace states that have started window shopping, and the average increase for that same example couple is typically over $20,000 annually,” said Gideon Lukens of the Center on Budget and Policy Priorities, citing an example of a 60-year-old Idaho couple facing an $18,000 annual increase.

Industry Response

For carriers, the challenge extends beyond pricing. Joel White, president of the Council for Affordable Health Coverage, said some states are reviving high-risk pool models to stabilize markets. “Those risk pools lowered premiums in those markets by an average of about 20 percent,” he said.

Kelly, in Idaho, urged consumers to act early and seek licensed broker assistance, noting that 71 per cent of enrollees in the state rely on professionals for marketplace enrollment. “We stand ready to move mountains, if needed, to make sure that Idahoans receive all the savings that they’re eligible for,” he said.

Outlook for Insurers

Insurers face a pivotal year as they navigate rising claims costs and subsidy uncertainty. The 2026 enrollment cycle could determine whether the ACA marketplace sustains its current scale or enters another cycle of volatility reminiscent of its early years. Analysts say the market’s stability will depend heavily on legislative decisions in the coming weeks and insurers’ ability to manage adverse selection.
