We predict the neutrino-nucleon cross section at ultrahigh energies relevant in connection with the search for high-energy cosmic neutrinos. Our investigation, employing the color-dipole picture, among other things allows us to quantitatively determine which fraction of the ultrahigh-energy neutrino-nucleon cross section stems from the saturation versus the color transparency region. We disagree with various results in the literature that predict a strong suppression of the neutrino-nucleon cross section at ultrahigh energies.
