We study the effects of soft gluon resummation in the absolute mass threshold limit for the production of four top quarks at the LHC. We obtain predictions for the cross section at next-to-leading logarithmic (NLL) accuracy, additionally considering $\mathcal{O}(\alpha_s)$ non-logarithmic contributions that do not vanish at threshold. The numerical results show a reduction of the theoretical error associated with the scale uncertainty by up to a factor of 2.
