In this Letter, we bring together two topics in the holographic
correspondence - quantum chaos and quark-gluon plasma (QGP). We establish that
the first relativistic correction to drag force experienced by a charge carrier
moving through a thermal medium (for example, a quark in QGP) at a constant
velocity is fixed by the butterfly velocity. Moreover, we show that this result
is robust against stringy corrections and anisotropy. For the jet quenching
parameter, we find that it is related to the butterfly velocity along the
momentum broadening direction and temperature in the spirit of the ``Planckian
bound''. This opens a way to the reconstruction of butterfly velocity of
quark-gluon plasma and other strongly-coupled systems experimentally from
rather simple observables.
