# Atlas Commons research objects — ACA marketplace coverage for Wisconsin (2026) — context brief

Wisconsin's ACA marketplace coverage from the CMS ACA Plan Attributes PUF, with each figure's epistemic status labeled: every plan count — medical plans, standalone dental plans, and breakdowns by metal level, plan type, HSA-eligibility, and referral requirement — is a measured census of plans offered (counts of rows in the CMS file, all labeled RECORDED); the sticker premium landscape by metal tier (40yo, pre-subsidy) is a recorded set of published CMS Rate PUF rates, with the subsidy note labeled CONTEXT; the boundary note is context (labeled CONTEXT) — these count plans offered and their sticker price, not enrollment, the insured rate, or net cost after subsidies. Sources: CMS ACA Plan Attributes PUF, CMS Marketplace Rate PUF. CC0.
