The word both is a determinative (in the terminology of CGEL). Determinatives are not per se singular or plural (except these and those), but they select singular or plural nouns. When both appears without the head noun, as it does here, there is a fusion of functions and it becomes both the determiner and the head of the plural NP. The verb then agrees with the plural NP.
