We prove that the eigenvalues of a continuum random Schrödinger operator −∆ + Vω of Anderson type, with complex decaying potential, can be bounded (with high probability) in terms of an Lq norm of the potential for all q ≤ d + 1. This shows that in the random setting, the exponent q can be essentially doubled compared to the deterministic bounds of Frank (Bull. Lond. Math. Soc., 2011). This improvement is based on ideas of Bourgain (Discrete Contin. Dyn. Syst., 2002) related to almost sure scattering for lattice Schrödinger operators.
