Abstract
We prove the existence of a global family with natural universal properties over every component of the moduli space of marked irreducible holomorphic symplectic manifolds. The analogous result follows for Teichmüller spaces.

I thank Zhiyuan Li for his interesting talk, and for asking whether universal families exist over Teichmüller spaces of holomorphic symplectic manifolds, at the workshop “Hyper-Kähler Manifolds, Hodge Theory, and Chow Groups” at the Tsinghua Sanya International Mathematics Forum in December 2016. I thank the organizers, Radu Laza, Kieran O’Grady, and Claire Voisin for the invitation to this interesting and instructive workshop. I thank Daniel Huybrechts and Sukhendu Mehrotra for helpful communications and for their comments on an earlier draft of this article. I thank Jenia Tevelev for Remark 3.8. Finally, I thank the referees for numerous insightful comments and suggestions.
