Federal budget bills under the Trump administration have advanced major proposals reducing federal Medicaid funding and changing its structure. As an example, the “One Big Beautiful Bill Act,” enacted in 2025, is expected to cut more than $1 trillion in federal Medicaid support over 10 years. It also implements work requirements and higher cost-sharing, potentially trimming coverage and funding for select groups. These updates are likely to push increased Medicaid costs to states and hold back federal support growth, even as enrollment remains high across the country.
