New federal budget legislation passed during the Trump administration features major initiatives to reduce Medicaid’s federal funding and restructure the program going forward. Notably, the “One Big Beautiful Bill Act,” signed into law in 2025, is set to cut federal Medicaid spending by more than $1 trillion over 10 years, adding requirements like work mandates and heightened cost-sharing that could reduce benefits and funding for a segment of recipients. These adjustments may require states to shoulder more program costs and restrict growth in federal Medicaid support as the program continues to cover millions of Americans.
