New results on $B_{(s)}^0 \to \mu^+ \mu^-$ decays are reported using proton-proton collision data corresponding to 18 fb$^{-1}$ recorded with the LHCb Upgrade I detector at $\sqrt{s} = 13.6$ TeV during 2024 and 2025. The results are combined with those obtained from LHCb data collected during Run 1 and Run 2. Updated values of the branching fraction and effective lifetime of the $B_s^0 \to \mu^+ \mu^-$ decay are shared, along with progress in the search for the $B^0 \to \mu^+ \mu^-$ decay.
