Recent federal budget laws enacted during the Trump administration have featured notable measures to decrease federal Medicaid funding and restructure aspects of the program. The “One Big Beautiful Bill Act,” which became law in 2025, is expected to cut federal Medicaid funding by more than $1 trillion over the next decade and bring new policies such as work requirements and higher cost sharing for some recipients. These shifts could mean greater responsibility for states and slower federal Medicaid spending growth, even as usage remains high among millions of Americans.
