We calculate the magnetic dipole moment of the newly observed charged hidden-charmed open strange state, recently observed by BESIII Collaboration. Based on the information provided by the experiment and theoretical studies followed the observation, we assign the quantum numbers and the quark composition to this state and estimate the magnetic dipole moment of this resonance in both the compact diquark–antidiquark and molecular pictures. We apply the light cone QCD formalism and use the distribution amplitudes of the on-shell photon with different twists. The obtained results in both pictures are consistent with each other within the errors. The magnitude of the magnetic dipole moment shows that it is accessible in the experiment.
