Rocket Lab RKLB, Astera Labs ALAB, CoreWeave CRWV, Nebius NBIS, and Teradyne TER are joining the Nasdaq-100 on June 22, knocking out Charter Communications CHTR, Cognizant CTSH, Insmed INSM, Verisk Analytics VRSK, and Zscaler ZS in the quarterly rebalance. Rocket Lab jumped 6.54% in premarket, Nebius gained 4.44%, CoreWeave added 3.30%, and Astera Labs rose 3.14%.

The five additions reflect the index’s growing tilt toward AI infrastructure and space technology. CoreWeave and Nebius are both AI cloud providers, while Astera Labs designs high-speed connectivity chips for AI data centers. Rocket Lab has emerged as a leading small satellite launch provider. The inclusions follow Marvell Technology’s addition to the S&P 500, also effective June 22, as benchmark rebalances increasingly favor AI-linked names.

SpaceX, set to begin trading Friday under SPCX, could eventually land in the index too once it clears eligibility requirements. The June 22 rebalance also coincides with Marvell Technology joining the S&P 500 on the same date.
