The value of X is determined only as Craterhoof Behemoth’s triggered ability resolves, potentially including Craterhoof Behemoth itself. It won’t change later in the turn if the number of creatures you control changes.

Craterhoof Behemoth’s triggered ability affects only creatures you control at the time it resolves. It won’t affect creatures that come under your control later in the turn.
