Rare $B$ decays at LHCb, such as those mediated via ${b\to s\mu^{+}\mu^{-}}$ transitions, offer sensitivity to heavy New Physics particles. Over the last decade, a pattern of coherent tensions between observables measured in ${b\to s\mu^{+}\mu^{-}}$ transitions and their Standard Model predictions have emerged.
An overview of the recent measurements by LHCb in ${b\to s\mu^{+}\mu^{-}}$ transitions are summarised in these proceedings, highlighting the tensions observed in both branching fraction measurements and angular analyses. Furthermore, the future prospects for the field are outlined.
