Five companies will be added to the Nasdaq 100 on June 22, 2026, even as SpaceX, fresh from a $75 billion IPO and a June 12 Nasdaq debut, sits ready to force another near-term adjustment. Nasdaq Global Indexes said Astera Labs, CoreWeave, Nebius, Rocket Lab and Teradyne will replace Charter Communications, Cognizant Technology Solutions, Insmed, Verisk Analytics and Zscaler when the rebalance takes effect prior to the market open on June 22. The change matters for funds that track the Nasdaq 100: Nasdaq says more than 200 investment products, with combined assets exceeding EUR 800 billion, follow the index and will need to trade to match the new line-up. Nasdaq’s late March rule change allows a newly listed company to be eligible for the Nasdaq 100 as soon as 15 trading days after listing.

The scheduled rebalance looks routine, yet the timing collides with SpaceX’s blockbuster listing, making the June reshuffle anything but ordinary.

Who moves in, who moves out

Nasdaq Global Indexes named the five entrants and the five departures in its June quarterly rebalance announcement. Incoming are Astera Labs, a connectivity chips specialist; CoreWeave, which supplies GPU-driven cloud computing; Nebius, another cloud and compute entrant; Rocket Lab, the only space-industry company among the additions; and Teradyne, a supplier of chip-equipment tools. Exiting the index are Charter Communications, Cognizant Technology Solutions, Insmed, Verisk Analytics and Zscaler.

The new cohort spans distinct corners of the market: space technology, chip manufacturing and GPU cloud services. Rocket Lab’s inclusion marks a notable step for the commercial space sector into the Nasdaq-100 benchmark, while CoreWeave and Nebius reflect demand for specialised cloud infrastructure linked to artificial intelligence workloads. Teradyne’s arrival flags the index’s exposure to semiconductor capital equipment, a cyclical area that can amplify moves in a tech-heavy benchmark.

Index composition changes feed directly into the work lists of funds that track the Nasdaq 100. Nasdaq says more than 200 investment products, with combined assets exceeding EUR 800 billion, reference the index. That means exchange-traded funds, mutual funds and other passive vehicles will need to buy the five incoming names and sell the five outgoing companies ahead of the June 22 effective date.

Mastheads

The mechanical rebalance creates predictable flows. Large passive managers and institutional traders will execute buys and sells in the run-up to the rebalance, and that trading can move prices, especially in smaller constituents.

For retail households who hold Nasdaq-linked ETFs, the effect is indirect but real: the weights inside those products change, altering exposure to particular technologies and sectors without investors having to act themselves.

Narrowly, Rocket Lab’s addition could attract fresh demand if funds must purchase shares to reach index weights. Broadly, the reshuffle marginally shifts which technologies the Nasdaq 100 represents, nudging more capital toward cloud GPU providers and chip-equipment manufacturing while trimming exposure to the outgoing list of media, services and analytics firms.

Policy and rule changes at index providers alter how quickly markets adjust. Nasdaq moved in late March to allow newly listed companies to become eligible for the Nasdaq 100 after just 15 trading days, a faster path than previously permitted. That rule change creates a separate wrinkle for this cycle: SpaceX, which raised $75 billion in its IPO and began trading on Nasdaq on June 12, could become eligible to join the Nasdaq 100 within weeks of listing.

S&P Dow Jones Indices took a different view. The major rival decided against a similar acceleration, keeping the S&P 500 on its customary timetable and thereby blocking any expedited entry for SpaceX into that benchmark. The divergence in index governance means a post-IPO shuffle is more plausible on Nasdaq than on the S&P 500, and that asymmetry can influence where capital flows after a large initial public offering.

For index funds and managers the practical calendar is now clear. Nasdaq fixed June 22, 2026 as the date the June quarterly rebalance will take effect.
