@customdesigned positronium exists pretty much anytime antimatter-matter collisions take place. They go through a process where they form positronium first, and then after a short halflife will decay into photons. But they dont directly annihilate, just like any other matter they fall into orbitals first until they give off enough energy to reach ground state, their ground state is just annihilation
