Abstract
In this article, we define and study the class of simple transitive $2$representations of finitary $2$categories. We prove a weak version of the classical JordanH{\"o}lder Theorem where the weak composition subquotients are given by simple transitive $2$representations. For a large class of finitary $2$categories we prove that simple transitive $2$representations are exhausted by cell $2$representations. Finally, we show that this large class contains finitary quotients of $2$KacMoody algebras.
