In a previous paper, we proved that the 1-d periodic fractional Schrödinger equation with cubic nonlinearity is locally well-posed in ${{H}^{s}}$ for $s>1-\alpha /2$ and globally well-posed for $s>10\alpha -1/12$. In this paper we define an invariant probability measure $\mu$ on ${{H}^{s}}$ for $s<\alpha -1/2$, so that for any $\text{ }\!\!\varepsilon\!\!\text{ }>0$ there is a set $\Omega \subset {{H}^{s}}$ such that $\mu \left( {{\Omega }^{c}} \right)<\text{ }\!\!\varepsilon\!\!\text{ }$ and the equation is globally well-posed for initial data in $\Omega$. We see that this fills the gap between the local well-posedness and the global well-posedness range in an almost sure sense for $\frac{1-\alpha }{2}<\alpha -\frac{1}{2},i.e.,\alpha >\frac{2}{3}$ in an almost sure sense.
