The main physics goals of the AMS-02 experiment in the astroparticle domain are searches for antimatter and dark matter. The discovery potential of primordial antimatter by AMS-02 is presented, emphasizing the completeness of the AMS-02 detector for these searches. Meanwhile, antiproton detection suffers from a large secondary interaction background; the anti-He-4 or anti-He-3 signal would allow one to probe the Universe for existence of antimatter. The expected signal in AMS-02 is presented and compared to results from present experiments. The e(+) and antiproton channels will contribute to the dark matter detection studies. A SUSY neutralino candidate is considered. The expected flux sensitivities in a three-year exposure for the e(+)/e(-) ratio and antiproton yields as a function of energy are presented and compared to other direct and indirect searches.
