The cosmic ray p ̄/p data from 20 to 450 GeV measured by AMS-02 can be interpreted in terms of DM. By using the GALPROP code, the propagation with DM annihilating to anti-protons is calculated based on the conventional model. The b ̄b, uu ̄ and W+W− final states are considered with different DM masses and annihilating cross-section as free parameters. To see the goodness of fit, the chi-squared test will be used. Once the best-fit parameters are found, the possibility of DM can be discussed.
