What it means
わけだ expresses a conclusion that follows naturally from known facts or information. It can mean “it means that,” “so,” or “no wonder,” depending on context. The speaker presents the conclusion as something that now makes sense, rather than as a simple statement of fact. It follows a plain-form clause, while nouns and na-adjectives normally require な before わけだ.
Usage note
わけだ is different from わけではない, which means “it does not mean that” or softens a generalization. The polite counterpart is わけです.
