The effect of an inflaton scalar field on cosmic rotation is discussed. It is shown that any physically reasonable inflaton scalar will dilute the cosmic vorticity by a factor of R −3γ when the false vacuum decays into matter. Since vorticity decays during inflation as R 3γ‐5 , this leads to a total decay by a factor of R 5 , which is not dependent on the equation of state of the rotating non‐vacuum component of the energy‐momentum tensor.
