In addition, I’ll mention:
Foretold is tracking ~20 questions and is open to anyone adding their own, but doesn’t have very many predictions.
In addition to the one you mentioned, Metaculus is tracking a handful of other questions and has a substantial number of predictions.
The John Hopkins disease prediction project lists 3 questions. You have to sign up to view them. (I also think you can’t see the crowd average before you’ve made your prediction.)
