We review the prospects for SUSY searches at the LHC and at electron positron linear colliders in light of recent constraints on the relic density of cold dark matter as well as those from the determination of muon anomalous magnetic moment and rare decays of bottom mesons, using the mSUGRA model to guide our thinking. The WMAP measurement requires a neutralino relic density somewhat lower than the typical model value, so that efficient neutralino annihilation is required. We find several qualitatively different regions of the mSUGRA parameter space that are favoured by the WMAP data: unless tan beta is very large, experiments at the LHC should be able to probe most of these regions. An important exception is the region with small mu and large values of universal scalar and gaugino masses, where the LSP has a considerable higgsino component and is close in mass to the chargino. We find that linear colliders should be able to probe parts of this region not accessible at the LHC.
