I wasn't familiar with the Center for Research in Security Prices (CRSP). Apparently they were acquired by Morningstar in February 2026. I also found this press release from Vanguard announcing they will be updating fund names (including VTI) to reflect the acquisition https://corporate.vanguard.com/content/corporatesite/us/en/corp/who-we-are/pressroom/press-release-vanguard-to-update-names-of-us-equity-index-funds-tracking-morningstar-indexes-042926.html https://corporate.vanguard.com/content/corporatesite/us/en/c... but nothing on the fund composition or rule changes.
