Centene Corporation
The largest Medicaid managed-care company and the largest ACA exchange insurer in the United States. Centene grew from a single Milwaukee Medicaid plan into a Fortune-top-25 government-programme insurer by winning state contracts one at a time and then buying its peers (Health Net 2016, Fidelis Care 2018, WellCare 2020, Magellan 2022). Its whole business depends on public payers: state Medicaid agencies, CMS and federal exchange subsidies. In 2025 that dependence showed up as one of the sharpest earnings collapses in managed-care history.
