  Recent progress on the (g-2)_\mu prediction is presented. In the SM, the
Higgs-boson mass dependent contributions have been evaluated exactly up to the
two-loop level and consistently combined with leading three-loop effects. Thus,
the currently most accurate value including a detailed error analysis for the
SM electroweak contributions has been obtained. The SUSY two-loop corrections
from fermion/sfermion-loop insertions have been computed; they are generally
large and logarithmically enhanced for heavy squarks.
