We investigate Planck-scale boundary conditions on Higgs quartic interactions and their β functions in the Standard Model augmented by an additional complex scalar. We use renormalization group running at two loops, and include both theoretical and experimental constraints. We find that the boundary condition λ = β λ = 0 at the Planck scale is compatible with the current Higgs and top mass measurements, but requires additional scalars lighter than about 600 GeV.
