Aspects of the present disclosure relate to control of speculative demand loads. In some embodiments, the method includes receiving instructions for a branch in a program, detecting the branch load is in the cache, monitoring a number of completed loads for the program, determining a cache pollution ratio of executed loads to completed loads, providing the cache pollution ratio to a branch prediction unit, and altering load instructions for the branch based on the cache pollution ratio.
