As far as we know, Datomic's (noninteractive) transactions are ACID. You would do better to ask them, though. The list isn't intended to be exhaustive!
From what I understand, Datomic sidesteps the ACID issue altogether by dealing with immutable data at the application layer. You add your changes on top of a version of the database, so you're always working on a consistent view of the database (pretty much like Git).
On the backend, Datomic doesn't implement it's own storage, it plugs into SQL databases, Riak, etc. so you may or may not have ACID at that level.
