The current ~ 3.5σ discrepancy between the experimental measurement and theoretical prediction of the muon magnetic anomaly, aµ, stands as a potential indication of the existence of new physics. The Muon g - 2 experiment at Fermilab is set to measure aµ with a four-fold improvement in the uncertainty with respect to previous experiment, with an aim to determine whether the g - 2 discrepancy is well established. The experiment recently completed its first physics run and a summer programme of essential upgrades, before continuing on with its experimental programme. The Run-1 data alone are expected to yield a statistical uncertainty of 350 ppb and the publication of the first result is expected in late-2019.
