Bloomberg 500 (B500) Index Adds Sixteen Securities Following Semi-Annual Reconstitution
NEW YORK, Aug. 27, 2025 /PRNewswire/ -- Bloomberg Indices announced the following changes to the Bloomberg 500 (B500) Index effective prior to the open of trading on Thursday, September 11, to coincide with the semi-annual reconstitution of the index. The B500 contains the 500 most highly capitalized US companies weighted by float market cap, reflecting a market capitalization of $58.19 trillion.
Affirm Holdings, Inc. (AFRM), Astera Labs, Inc. (ALAB), The Carlyle Group, Inc. (CG), CyberArk Software, Ltd. (CYBR), EMCOR Group, Inc. (EME), Comfort Systems USA, Inc. (FIX), Insmed, Inc. (INSM), International Paper Company (IP), Jabil, Inc. (JBL), NiSource, Inc. (NI), NRG Energy, Inc. (NRG), Nutanix, Inc. (NTNX), Rocket Lab Corporation (RKLB), SoFi Technologies, Inc. (SOFI), Tapestry, Inc. (TPR), and Viking Holdings Ltd. (VIK) will enter the index. These equities span a variety of sectors, but Technology is most represented amongst this set, with Financial and Industrials directly following.
Changes to the B500 Index reflect the results of a purely rules-based index design focused on measuring markets with transparency and representativeness beyond market capitalization alone. As a result, the B500 mitigates potential biases and systematically evaluates potential members, which may lead to earlier additions of qualified companies when compared to indices using a committee-based approach.
