The BFSS Matrix model can be regarded as a theory of coincident M‐theory gravitons. In this spirit, we summarize how using the action for coincident gravitons proposed in hep‐th/0207199 it is possible to go beyond the linear order approximation of Kabat and Taylor, and to provide a satisfactory microscopical description of giant gravitons in AdS m × S n backgrounds. We then show that in the M‐theory maximally supersymmetric pp‐wave background, the action for coincident gravitons, besides reproducing the BMN Matrix model, predicts a new quadrupolar coupling to the M‐theory 6‐form potential, which supports the so far elusive fuzzy 5‐sphere giant graviton solution. Finally, we discuss similar Matrix models that can be derived in Type II string theories using dualities.
