In this paper, we study the phase space of a phantom model with O(N) symmetry in an exponential potential. Different from the model without O(N) symmetry, the introduction of the symmetry leads to a lower bound w>\ensuremath-3 on the equation of state for the existence of a stable phantom dominated attractor phase. The reconstruction relation between the potential of the O(N) phantom system and redshift has been derived.
