Dynamic Open Radio Access Network Radio Unit (O-RU) sharing between multiple tenant Open RAN Distributed Units (O-DU) may be provided. A Near Real Time RAN Intelligent Controller (nRT-RIC) may receive tenant policies for a first tenant and a second tenant. The nRT-RIC may then determine initial sharing templates for the first tenant and the second tenant based on the tenant policies. The nRT-RIC may send the initial sharing templates to a first tenant Distributed Unit (DU) and a second tenant DU. The nRT-RIC may receive operating metrics from the first tenant DU and the second tenant DU. The nRT-RIC may then determine operational factors based on the operating metrics. The nRT-RIC may alter an allocation of resources between the first tenant and the second tenant based on the operational factors. Finally, the nRT-RIC may send the altered allocation of resources to the first tenant DU and the second tenant DU.
