The availability at the LHC of the largest collision energy in pp collisions allows a significant advance in the measurement of \(J/\psi\) production as function of event multiplicity. The interesting relative increase observed with data at the LHC at \(\sqrt{s} = 7\,\mathrm{TeV}\) and at RHIC at \(\sqrt{s} = 0.2\,\mathrm{TeV}\) is studied now at unprecedented multiplicities at \(\sqrt{s} = 13\,\mathrm{TeV}\), The measurement at mid-rapidity in the dielectron channel with ALICE is presented and discussed in comparison to predictions from available theoretical models and to data at lower energies.
