The combination of new cosmic microwave background data with cosmological priors has determined the physical cold dark matter (cdm) density to be $\Omega_{\rm cdm} h^2 = 0.13\pm0.01$. We find the corresponding regions of parameters in the minimal supergravity model for which the lightest neutralino is the cdm particle. We then compare with the muon anomalous magnetic moment ($a_\mu$) measurement, the mass of the lighter CP-even Higgs boson ($h^0$), the trilepton search at the upgraded Fermilab Tevatron collider, and a direct search for relic neutralinos. The intersection of $\Omega_{\rm cdm} h^2$ and $a_\mu$ constraints selects $\tan\beta\approx 40-45$.
