No, an antimatter black hole is literally just a black hole. They're the same thing.

Energy density and mass density are the same thing too. A kilogram of hydrogen next to a kilogram of antihydrogen gravitates in exactly the same way as ~10^17 joules of equivalently distributed photons. The only difference is that the photons won't stay equivalently distributed for long.
- User23 3y agoI asked my particle physicist buddy about this and he pointed me here[1]. It sounds like you're giving the "classical" answer, but it's an area of open discussion. He thinks it could conceivably emit energy as gravitational waves.

- nyssos 3y agoThe no-hair theorem very likely goes through semiclassically as well, at least where global symmetries like baryon number are concerned, but yes, ultimately no one knows for sure what the story is for the undiscovered true theory of quantum gravity.
