Using Lurie's theory of infinite operads, we construct a symmetric monoidal structure on the infinite category of all functors (from small stable infinite categories to spectra) that satisfy additivity. The unit of this symmetric monoidal structure is the algebraic K-theory functor and (E-infinite) algebras correspond to the lax (symmetric) monoidal functors. As applications we show that the space of multiplicative structures on the algebraic K-theory functor is contractible, and that the cyclotomic trace can be characterized as the unique multiplicative natural transformation from K-theory to THH.
