VTI in turn is the primary holding of most of Vanguard's Target Date retirement funds, which are widely held in 401ks.

Total market indexes and target date funds will include this and SpaceX on float adjusted basis I believe. The blast radius is much larger than funds that track the NASDAQ directly.
