Dark matter in the Universe is likely to be made up of some new, hypothetical particle which would be a part of an extension of the Standard Model of particle physics. After a general introduction, in this talk I present in the framework of two popular unified supersymmetric models Bayesian statistics results for neutralino dark matter in the context of direct detection in underground experiments, and in indirect detection modes of relevance to Fermi and Pamela. While prospects for direct detection look excellent, those for Fermi strongly depend on poorly known cuspiness of the galactic halo in the central region of the Milky Way. Positron flux in those models appears to be significantly below the Pamela result, which on the other hand, may be explained in terms of nearby pulsars.
