The mass and decay constant of the $X(5568)$ state newly observed by D0 Collaboration are computed within the two-point sum rule method using the diquark-antidiquark interpolating current. In calculations, the vacuum condensates up to dimension 8 are taken into account. The obtained result for the mass of the $X(5568)$ state is in a nice agreement with the experimental data.
