Using the Run-I data delivered by the LHC, several exotic states are observed or searched for. The most recent LHCb results are reported, including the search for the $B_s^0 \pi^{pm}$ state, the observation of four $J/\psi \phi$ structures in $B^+\to J/\psi \phi K^+$ decays, and the observation of $J/\psi p$ resonances consistent with pentaquark states in $Lambda_b^0 \to J/\psi p K^-$ decays. The results on $J/\psi \phi$ from the CMS collaboration are also discussed.
