This increase amounts to nearly 40% growth in just several years, largely powered by swelling enrollment and higher use of medical services during and following the pandemic.
Federal budget legislation during the Trump administration introduced major proposals affecting federal Medicaid support. The “One Big Beautiful Bill Act,” signed into law in 2025, is forecasted to cut federal Medicaid spending by more than $1 trillion over the next 10 years and implement measures like work requirements and increased cost-sharing that may lower coverage and funding for some participants. These shifts are expected to require states to shoulder a greater share of costs and restrict the rate of growth for federal Medicaid contributions, even as the program continues to provide for millions in the U.S.
