The Subjunctivisor!

Does aunque require the subjunctive?

Aunque may require the subjunctive, depending on the certainty and reality of the subordinate clause:

Por ejemplo …

Vengo aunque no tengo dinero.
I’ll come even though I don’t have any money. (Fact: I know I don’t)

Vengo aunque no tenga dinero.
I’ll come even if I don’t have any money. (I don’t know if I have any).
