Minnesota has around 151,000 residents enrolled in ACA exchange plans, 61% of whom are currently subsidized. I estimate they also have another ~62,000 unsubsidized off-exchange enrollees.
Kansas has around 200,000 residents enrolled in ACA exchange plans, 94% of whom are currently subsidized. I estimate they also have another ~6,000 unsubsidized off-exchange enrollees.
Kentucky has around 97,000 residents enrolled in ACA exchange plans, 86% of whom are currently subsidized. I estimate they also have another ~6,800 unsubsidized off-exchange enrollees.
Indiana has around 359,000 residents enrolled in ACA exchange plans, 90% of whom are currently subsidized. I estimate they also have another ~6,700 unsubsidized off-exchange enrollees
Iowa has around 136,000 residents enrolled in ACA exchange plans, 88% of whom are currently subsidized. I estimate they also have another ~9,600 unsubsidized off-exchange enrollees.
According to the new report, total enrollment from September through November actually increased by just a hair (5,377) and still remained at over 20.7 million nationally, so it doesn't look like the Trump Admin has started cooking these particular books, at least not yet.
I've been able to cobble together more recent ACA expansion enrollment for about half of the 40 states (+DC) which participate in the program:
Hawaii has around 26,000 residents enrolled in ACA exchange plans, 83% of whom are currently subsidized. I estimate they also have perhaps another ~1,700 unsubsidized off-exchange enrollees.
Idaho has around 117,000 residents enrolled in ACA exchange plans, 86% of whom are currently subsidized. I estimate they also have another ~9,000 unsubsidized off-exchange enrollees, although the actual rate filings (summarized later in this post) put the off-exchange total at a much higher ~47,000.
Combined, that's 6.2 - 8.0% of their total population.
Alabama has around 477,000 residents enrolled in ACA exchange plans, 96% of whom are currently subsidized. I estimate they also have perhaps another ~33,000 unsubsidized off-exchange enrollees.
Tennessee ACA exchange carriers were instructed to provide two sets of rate filings for 2026: One which assumes CSR reimbursement payments won't be reinstated, one which assumes they are reinstated. In addition, both sets of filings assume that IRA subsidies won't be extended; all but one carrier clarified how much extending the IRA subsidies would impact 2026 premium changes.
Alliant Health Plans: Alliant is requesting a nominal 0.3% increase next year if CSR payments aren't reinstated and a 1.0% drop if they are. In both cases, premiums would be 2.8% lower if IRA subsidies were to be extended by Congress:
