  There is a long standing discrepancy between the Standard Model prediction
for the muon g-2 and the value measured by the Brookhaven E821 Experiment. At
present the discrepancy stands at about three standard deviations, with a
comparable accuracy between experiment and theory. Two new proposals -- at
Fermilab and J-PARC -- plan to improve the experimental uncertainty by a factor
of 4, and it is expected that there will be a significant reduction in the
uncertainty of the Standard Model prediction. I will review the status of the
planned experiment at Fermilab, E989, which will analyse 21 times more muons
than the BNL experiment and discuss how the systematic uncertainty will be
reduced by a factor of 3 such that a precision of 0.14 ppm can be achieved.
