Séminaire de géométrie arithmétique A longstanding question in the theory of Shimura varieties concerns their perfectoidness at infinite level — a property that would reveal deep connections between étale and coherent cohomology. In this talk, we establish a criterion for perfectoidness via Sen theory, building on a new development of p-adic Hodge theory for general valuation fields that extends T
