The muon anomalous magnetic moment has been of interest for the HEP field for over a decade as a possible sign of beyond-the-standard-model physics.   In June 2025, the Fermilab Muon g-2 collaboration released their final result of the muon anomalous magnetic moment with a 125 ppb total uncertainty.  

The measurement is now in agreement with the consensus Lattice QCD theoretical predictions released in 2025. I will review physical motivation, the theory, describe the measurement, and comment on any remaining mysteries.
