The dynamic behaviour of solitons in the random anharmonic chain in the long‐wavelength approximation is investigated. Long‐time accumulative effects are described of weak stochastic perturbations on Korteweg‐de Vries solitons. A law is found of the stochastic acceleration of solitons and the amplitude of a soliton is calculated in the case of short‐range fluctuations of the spatial inhomogeneities of the chain.
