We propose a novel mechanism for the removal of a Dark Matter halo from a Globular Cluster: Through multi-body gravitational interactions, a Dark Matter particle can be accelerated above the escape speed of the cluster and be ejected. We find that this mechanism is not sufficient to eject a massive, extended Dark Matter halo by the present time. Combined with observations of isolated Globular Clusters that show no evidence of tidal stripping, these results suggest that Globular Clusters likely never possessed significant Dark Matter halos.
