What you can actually buy here
7 insurers sell into Pima County. This is a crowded market by national standards. Crowded markets are cheaper on average and much harder to shop, because the plan names stop meaning anything by the third carrier and the differences that matter get buried in documents nobody opens. Between them they offer 86 plans, about 12 for each insurer, which is a normal-sized list to work through once you know which network you need. The count is unchanged from last year, so the networks you compared previously still stand.
46,020 marketplace plan selections were recorded in Pima County for 2026 — only 57 per thousand under-65 residents, against a typical 127 across the counties covered here. Employer coverage dominates locally, which has a specific consequence: when it goes, fewer people around you have any experience of what to do next. 6,630 of them were new consumers and 39,390 were renewals — a 14% new share, close to the national pattern. Roughly one in six enrollees here arrived within the year.
