In recent years, federal budget measures under the Trump administration have featured major proposals to reduce federal Medicaid funding and alter program structure. For instance, the “One Big Beautiful Bill Act,” enacted in 2025, is anticipated to cut over $1 trillion in federal Medicaid support over 10 years, implementing policies like work requirements and greater cost-sharing—actions likely to limit coverage and funding for certain beneficiaries. As a result, states are expected to take on higher costs while federal Medicaid growth slows, even as coverage extends to tens of millions nationwide.
