What you can actually buy here
4 insurers compete here. That is thin enough that switching carrier usually means switching hospital system too, and wide enough that the premiums genuinely differ. Both things are worth checking before either is dismissed. Between them they offer 44 plans, about 11 for each insurer, a short list by national standards. Short lists are easier to compare properly, which is a real advantage as long as one of them fits your doctors. The count is up from 2 last year. Insurers entering a county usually means they like what they see in the risk pool, and it tends to show up as more aggressive pricing the following year rather than immediately.
34,501 people here bought marketplace coverage for 2026, about 115 per thousand under-65 residents. That sits near the middle of the counties covered on this site: a working individual market, but most local coverage still arrives through an employer. 5,627 of them were new consumers and 28,874 were renewals — a 16% new share, close to the national pattern. Roughly one in six enrollees here arrived within the year.
