Given a complex reductive group G and a G-representation N, there is an associated Coulomb branch defined by Braverman, Finkelberg, and Nakajima. If X is a smooth semiprojective variety equipped with a G-action, and f is a G-equivariant proper holomorphic map from X to N, we show that the equivariant big quantum cohomology QH_G(X) defines a quasicoherent sheaf of algebras with coisotropic support on the Coulomb branch. Upon specializing the Novikov and bulk parameters, this sheaf becomes coherent with Lagrangian support. Our proof involves a novel description of the Coulomb branch and a generalization of shift operators using this description.
