The Nasdaq-100 index is welcoming five new members effective June 22, in a quarterly rebalancing that reflects the dominant themes driving global markets in 2026.
Four of the five incoming companies operate directly within artificial intelligence, semiconductor infrastructure, and high-performance computing, underscoring just how central these sectors have become to large-cap equity markets.
Astera Labs (NASDAQ: ALAB), CoreWeave (NASDAQ: CRWV), Nebius Group (NASDAQ: NBIS), and Teradyne (NASDAQ: TER) are the four AI and infrastructure-focused additions joining the prestigious index on June 22.
CoreWeave and Nebius Group both provide data center capacity and AI computing services, while Teradyne and Astera Labs occupy critical roles within the broader AI infrastructure supply chain.
Nebius Group, the AI-focused cloud platform spun out of Yandex, has surged 165% year-to-date and carries a market valuation of $56.4 billion heading into its index debut.
Astera Labs has been the standout performer among the incoming cohort, rising nearly 80% in the past month alone and 121% year-to-date as demand for its data-center connectivity chips continues to accelerate.
CoreWeave, the GPU cloud provider that completed its public offering earlier this year, enters the Nasdaq-100 with a market capitalization of $52.2 billion.
The fifth new addition is Rocket Lab (NASDAQ: RKLB), which stands apart from the AI-heavy group as a provider of rockets, end-to-end launch services, spacecraft, and satellite components to governments and private companies.
Rocket Lab’s inclusion comes as the broader space sector attracts growing investor attention, most notably following the record-setting IPO by Space Exploration Technologies, known as SpaceX, in recent weeks.
The company reported first-quarter revenue of $200.3 million, representing a 63% increase from the same period a year earlier, and posted a record backlog of $2.2 billion, up 20% from the prior quarter.
Rocket Lab also agreed this year to acquire Motiv Space Systems, a specialist in space robotic systems with experience supporting NASA Mars rover missions, further broadening its capabilities.
Five companies are being removed from the index to make room for the new entrants, with Charter Communications (NASDAQ: CHTR), Cognizant (NASDAQ: CTSH), Insmed (NASDAQ: INSM), Verisk Analytics (NASDAQ: VRSK), and Zscaler (NASDAQ: ZS) all departing before markets open on June 22.
The Nasdaq-100 is tracked by more than 200 investment products with over $800 billion in assets under management globally, including the heavily traded Invesco QQQ ETF.
Index inclusion carries significant market implications, as passive funds that track the Nasdaq-100 are required to purchase shares of newly added companies and liquidate positions in those being removed, generating substantial rebalancing flows.
The composition of this rebalancing cycle serves as a clear signal of where capital and growth momentum are concentrated, with AI infrastructure and space technology firmly at the forefront of the 2026 market landscape.
