Medicaid covers the bottom of the range in Utah
Utah expanded Medicaid, so there is no coverage gap here: adults under 138% of the poverty guideline — about $22,025 for one person — go to Medicaid rather than falling between it and the subsidy.
281,338 under-65 Utah residents are uninsured all the same, 9.3% of them — 20th of the 51 states and DC, and 0.9× the 26-state median of 9.9%.
How much choice Utah counties get
Counties in Utah carry between 2 and 5 insurers, so competition is fairly even across the state without being uniform.
No county in Utah is down to a single insurer. Since the previous plan year, 17 counties in Utah gained an insurer and none lost one.
Heavy marketplace use
382,473 Utah residents selected a marketplace plan for 2026. Against the state's under-65 population that is 127 per thousand, well above the 26-state median of 79, and 5th highest of the 26 states on this site.
Of those, 45,524 — 12% — were new rather than renewing, which is a fairly typical mix of new and renewing enrollees (24th of 26).
