It is shown that Fermi acceleration, which is inherent to time-dependent open-horizon two-dimensional billiards, leads to anomalous transport properties. The stochastic oscillations of the scatterers result in superdiffusion of particles with the mean squared displacement growing asymptotically quadratically in time: ⟨q2⟩∼t2.
