We study the Lyapunov exponent $\lambda_L$ in quantum field theories withspacetime-independent disorder interactions. Generically $\lambda_L$ can onlybe computed at isolated points in parameter space, and little is known aboutthe way in which chaos grows as we deform the theory away from weak coupling.In this paper we describe families of theories in which the disorder couplingis an exactly marginal deformation, allowing us to follow $\lambda_L$ from weakto strong coupling. We find surprising behaviors in some cases, including adiscontinuous transition into chaos. We also derive self-consistency equationsfor the two- and four-point functions for products of $N$ nontrivial CFTsdeformed by disorder at leading order in $1/N$.
