Vanguard is an investment house -they own on behalf of others, as Vanguard has a number of mutual funds and similar instruments which are themselves based on theoretical ownership of an entire market index or market subgroup (sector).
VOO, for instance (VERY popular) is meant to duplicate the moves of the S&P500 essentially exactly, as if you owned a single Share of each and every of the 500 companies in that Index.
So Vanguard "owns it", yes, but as a passive trustee for tens of thousands of individual investors/accounts.
