Federal budget acts passed under the Trump administration have included major proposals to trim federal Medicaid support and change the program’s structure. For instance, the “One Big Beautiful Bill Act,” enacted in 2025, is forecast to reduce federal Medicaid spending by over $1 trillion in the next decade. It introduces requirements like work mandates and higher cost sharing, potentially limiting benefits and funding for some recipients. These policies are expected to shift more financial responsibility to states and restrict the growth of federal Medicaid contributions, even with the program’s wide reach.
