The answer to all such statements , according to Objectivism, is: an arbitrary claim is automatically invalidated. The rational response to such a claim is to dismiss it, without discussion, consideration, or argument.
Regarding the meaning of “to invalidate”. It seems that Peikoff is using the statement in the context of a debate or conversation. As in, proper rules of debate demand that you ignore what the other guy said if it is judged to be an arbitrary claim.
Because in the context of “thinking”, to invalidate could mean to consider as false.
It’s difficult to integrate because arbitrary refers to nothing in particular (similar to a contradiction). But it’s not false. The arbitrary does not belong in the realm of reason and/or logic.
Perhaps invalid means false and/or arbitrary. Campbell interprets invalidate as meaning false and he may be mistaken.

“Automatically invalidated” appears to mean that whenever one identifies a statement as arbitrary, one is entitled, without further ado, to conclude that it is false, consequently ruling it out of any further consideration.
Now regarding another issue

A statement has to be put into a context in order to be judged as true, false, or arbitrary (or “possible,” “probable,” etc.). Further, the same statement can be true in one context, false in another, and arbitrary in yet another, although this might hinge on certain words that have different meanings in different contexts.
If I hear “tiger liked a moon”. I have no context, which tiger which moon etc., I also don’t know much about tigers or moons.
Clearly I can’t judge it as true or false, it’s meaningless.
By establishing context do you mean after studying the subject? (a masters degree in moons and tigers)
Nevertheless, the statement is still going to be meaningless even after that. There’s just not enough information there.
If you cannot establish context, do you automatically judge it as arbitrary? As in could lack of knowledge (on the listener’s part) also be a lack of context?
I would argue that absence of context, also can indicate arbitrary. (you don’t have to establish context to consider something arbitrary). Although it may be the “subjective” sense of arbitrary.
