We prove non-existence of solutions for the cubic nonlinear Schrödinger equation (NLS) on the circle if initial data belong to |$H^s(\mathbb{T}) \setminus L^2(\mathbb{T})$| for some |$s \in (-\frac18, 0)$|. The proof is based on establishing an a priori bound on solutions to a renormalized cubic NLS in negative Sobolev spaces via the short-time Fourier restriction norm method.
