Morningstar Inc. (NASDAQ: MORN) announced it will rebrand the CRSP Market Indexes to reflect the Morningstar brand, marking a milestone in its acquisition of the Center for Research in Security Prices from the University of Chicago.

The CRSP Market Indexes, which serve as benchmarks for over $3 trillion in assets under management, will be renamed in late July. Popular funds tied to these indexes include the Vanguard Total Stock Market Index Fund and Vanguard Mid-Cap Index Fund. The CRSP US Total Market Index will become the Morningstar US Total Market Index.

The indexes will maintain their current methodology and clients will experience no disruption during the transition, according to the company's statement. The rebranding affects indexes that span various market capitalizations, investment styles, and sectors in U.S. equities.

"The addition of CRSP has furthered our efforts to disrupt the costly, entrenched index industry with indexes that deliver more value at global scale to help benefit investors," said Morningstar CEO Kunal Kapoor.

Amelia Furr, president of Morningstar Indexes, noted that the company now has over $4.2 trillion in assets linked to its benchmarks across more than 370 investment products. The acquisition positions Morningstar as a provider of broad U.S. equity benchmarks commonly used in retirement plans.

The CRSP indexes have been recognized for their comprehensive market coverage and methodology designed to help reduce transaction costs for investors. The name changes are expected to take effect in late July 2026.
