We show that abstract Cuntz semigroups form a closed symmetric monoidal category. Thus, given Cuntz semigroups $S$ and $T$, there is another Cuntz semigroup $[![ S,T ]!] $ playing the role of morphisms from $S$ to $T$. Applied to $C^{ast }$-algebras $A$ and $B$, the semigroup $[![ operatorname{Cu}(A),operatorname{Cu}(B) ]!] $ should be considered as the target in analogs of the universal coefficient theorem for bivariant theories of Cuntz semigroups. Abstract bivariant Cuntz semigroups are computable in a number of interesting cases. We also show that order-zero maps between $C^{ast }$-algebras naturally define elements in the respective bivariant Cuntz semigroup.
