Recent federal budget measures under the Trump administration included major proposals to decrease federal Medicaid contributions and restructure the program. The “One Big Beautiful Bill Act,” enacted in 2025, is expected to reduce federal Medicaid spending by more than $1 trillion over the next 10 years and adds policies like work requirements and greater cost-sharing. These could result in less coverage and funding for some Medicaid recipients, requiring states to absorb greater costs even as the program continues to serve tens of millions.
