Is there a way to make objects in LakeFS publicly available via http.

Hi Clay, LakeFS authorization works like AWS IAM, you can create a policy for that. https://docs.lakefs.io/reference/authorization.html#fsreadall

From what I understand policies only apply to authenticated users. Is it possible to give a repository a policy that allows unauthenticated users to Read?

No it is not possible. Can you share your use case
