Nonsequential multiple ionization of atoms in intense laser fields is initiated by a recollision between an electron, freed by tunnelling, and its parent ion. Following recollision, the initial electron shares its energy with several bound electrons. We use a classical model based on rapid electron thermalization to interpret recent experiments. For neon, good agreement with the available data is obtained with an upper bound of 460 as for the thermalization time. This may be the shortest thermalization time measured to date.
