Market data: sources, method & downloads

A reproducible, dated transformation of CMS’s 2026 individual-market landscape file, with public data by county.

Provenance and scope

CMS / CCIIO publishes the original data. ICHRA Report transforms selected columns for this explorer. The import contains 97,082 plan/county/rating-area records, not that many unique plans or enrolled members.

Transformation and limitations

State and county codes retain their original identifiers. Each record retains its HIOS plan ID, rating area and source worksheet row. Six published adult premium scenarios are stored as integer cents. Exact duplicates are removed; conflicting duplicates stop the import. This release found zero duplicate records. Prices are not averaged across ages or counties, weighted by enrollment, or extrapolated to missing states.

Source update: August 26, 2026. Import: September 12, 2026. Refreshes require a new source review and release; this dataset does not update automatically. No 2027 premiums are inferred from it. Exact-age, tobacco, household and address-specific prices require an official quote.

These are CMS observations, not proprietary employer outcomes. Availability and external document links may change. Data transformations can contain errors; submit evidence through the correction form.
