What you can actually buy here
9 insurers sell into Harris 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 121 plans, about 13 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.
731,300 marketplace plan selections were recorded in Harris County for 2026, or 170 per thousand under-65 residents — above the 127 typical of the counties covered here.

Roughly one in six enrollees here arrived within the year.
