This paper investigates the stabilization problem for continuous‐time stochastic systems with multiple delays under continuous event‐triggered mechanisms, of which both static case and dynamic case are considered individually. In order to avoid zeno phenomenon in every sample path, a suspension time after each successful execution is forced for our event‐triggered mechanisms, resulting in intermittent detection of system states. Under such control strategy, we deduce mean square exponential stability of stochastic systems with multiple delays by means of Hanalay‐type inequality and obtain a delay‐dependent‐based and less‐conservative stabilization criterion without involving the upper bound of time delays. Besides, a co‐design procedure is proposed for linear controller and event‐triggered mechanisms. In the end, an illustrative example is presented to show effectiveness of the proposed co‐design procedure and contrasts the system performance under static and dynamic event‐triggered mechanisms.
