Abstract: Let $ K$ be the symmetric convex hull of $ m$ independent random vectors uniformly distributed on the unit sphere of $ \mathbb{R}^n$. We prove that, for every $ \delta>0$, the isotropy constant of $ K$ is bounded by a constant $ c(\delta)$ with high probability, provided that $ m\geq (1+\delta)n$.
