Vanguard is owned by the funds managed by the company and is therefore owned by the customers. It is a mutual funds company and the owners are those who have funds with them. The owners are us.
They include institutional investors as well as individual investors in their mutual funds, so saying that they are owned by their investor mutual funds can be a sleigh of hand. Someone who has invested 10 million with Vanguard has more voting rights than the average retiree or mom and pop investor. Plus institutional investors can invest billions and therefore have more votes. Their website has all the woke b.s. listed in its guiding principals, so yes the mutual funds own Vanguard but some mutual funds have more say than others. Since its “private” thus the same shadow people trying to control western society could be the controlling votes for Vanguard. So yes you may own some of Vanguard but depending on how much invested it may only be nominal.
