We describe the C2 ‐equivariant homotopy type of the space of commuting n ‐tuples in the stable unitary group in terms of Real K‐theory. The result is used to give a complete calculation of the homotopy groups of the space of commuting n ‐tuples in the stable orthogonal group, as well as of the coefficient ring for commutative orthogonal K‐theory.
