We study correlations of spin currents flowing through a Coulomb blockaded
quantum dot. While vanishing for elastic co-tunneling, these correlations
develop as the quantum dot enters the Kondo regime. They are a manifestation of
Kondo physics in quantum dots. We demonstrate that the spin current correlator
is non-perturbative in the Kondo coupling.
