### Description

We review the status of searches and measurements of exotic hadron states at ATLAS. Among them: the search for the beauty partner of $X(3872)$ charmonium state, the measurement of differential cross-section of the prompt and non-prompt production of $X(3872)$ in the $J/\psi \pi \pi$ final states, the search for the structure in the $B_s \pi$ invariant mass, reported by D0 experiment, search for exotic states in B-hadron decays: pentaquarks in $\Lambda_b$ decays and tetraquarks in $B$-meson decays. ATLAS results and ongoing analyses perspectives are highlighted together with CMS and LHCb results.
