than eighty years after the muon was first discovered, it is still a source of mystery. Indeed, experiments are underway or planned that use measurements of the muon's magnetic moment as a window to search for new physics — a central goal towards a deeper
understanding of the fundamental particles and their interactions. </span><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; font-weight: 400; color: rgb(0, 0, 0);">The current difference between experiment and Standard-Model
theory for the anomalous magnetic moment of the muon stands at 4.2 standard deviations. The Fermilab E989 experiment, which released their first measurement result in 2021, and the planned J-PARC E34 experiment aim to reduce the experimental uncertainties
by a factor of four. To leverage this anticipated improvement in experimental precision, and determine unambiguously whether or not new-physics effects contribute to this quantity, the theoretical errors must be made more reliable and reduced to a commensurate
level. The Muon g-2 Theory Initiative was formed in 2017 to provide platforms that facilitate interactions between the different groups to consolidate the Standard-Model prediction. Recent developments have created several puzzles in the evaluation of the
hadronic vacuum polarization contribution, which is the dominant source of theory uncertainty. I will review the current status of Standard Model theory for this quantity and map out the future prospects.</span></div>
