Abstract: We describe the moduli space of cubic hypersurfaces in $\mathbb {C}P^{4}$ in the sense of geometric invariant theory. That is, we characterize the stable and semistable hypersurfaces in terms of their singularities, and determine the equivalence classes of semistable hypersurfaces under the equivalence relation of their orbit-closures meeting.
