The discovery of superconductivity in infinite-layer nickelates has added anew family of materials to the fascinating growing class of unconventionalsuperconductors. By incorporating the strongly correlated multi-orbital natureof the low-energy electronic degrees of freedom, we compute the leadingsuperconducting instability from magnetic fluctuations relevant forinfinite-layer nickelates. Specifically, by properly including the dopingdependence of the Ni $d_{x^2-y^2}$ and $d_{z^2}$ orbitals as well as theself-doping band, we uncover a transition from $d$-wave pairing symmetry tonodal $s_\pm$ superconductivity, driven by strong fluctuations in the$d_{z^2}$-dominated orbital states. We discuss the properties of the resultingsuperconducting condensates in light of recent tunneling and penetration depthexperiments probing the detailed superconducting gap structure of thesematerials.
