How these numbers are made
- Members are visible members: CMS suppresses any plan-county cell of ten or fewer, so small counties undercount. Market share excludes employer group plans.
- Enrollment is Oct 2026. Centene is the parent organization Centene Corporation; its plans may sell under other brand names in each state.
- A state's twelve-month change, counties led and rating come from that state's page and carry its vintages.
- Every figure comes from public CMS data as Livmor reads it, and the page is rebuilt when a new month posts. Livmor Carrier Command, public CMS data.
