The proposed rates are preliminary and could change before being finalized in late summer. The analysis includes proposed rate changes from 312 insurers in all 50 states and DC.
It’s the largest rate change insurers have requested since 2018, the last time that policy uncertainty contributed to sharp premium increases. On average, ACA marketplace insurers are raising premiums by about 20 percent in 2026, KFF found.
Insurers said they wanted higher premiums to cover rising health care costs, like hospitalizations and physician care, as well as prescription drug costs. Tariffs on imported goods could play a role in rising medical costs, but insurers said there was a lot of uncertainty around implementation, and not many insurers were citing tariffs as a reason for higher rates.
But they are adding in higher increases due to changes being made by the Trump administration and Republicans in Congress. For instance, the majority of insurers said they are taking into account the potential expiration of enhanced premium tax credits.
Those subsidies, put in place during the COVID-19 pandemic, are set to expire at the end of the year, and there are few signs that Republicans are interested in tackling the issue at all.
If Congress takes no action, premiums for subsidized enrollees are projected to increase by over 75 percent starting in January 2026, according to KFF.
But some states are pushing back.
Arkansas Gov. Sarah Huckabee Sanders (R) on Wednesday called on the state’s insurance commissioner to disapprove the proposed increases from Centene and Blue Cross Blue Shield. The companies filed increases of up to 54 percent and 25.5 percent, respectively, she said.
“Arkansas’ Insurance Commissioner is required to disapprove of proposed rate increases if they are excessive or discriminatory, and these are both,” Huckabee Sanders said in a statement.
“I’m calling on my Commissioner to follow the law, reject these insane rate increases, and protect Arkansans."
