Nasdaq Adds 5 AI and Space Firms to Nasdaq-100 in June Rebalance

In a move reflecting the growing dominance of advanced technology sectors in financial markets, Nasdaq has announced the inclusion of five firms specializing in AI infrastructure and space technology into the Nasdaq-100 index. Astera Labs, CoreWeave, Nebius, Rocket Lab, and Teradyne will join the index effective June 22, 2026, replacing existing constituents such as Charter and Zscaler. This rebalance is highly significant as it directly impacts approximately $1.4 trillion in assets benchmarked to the index.

This adjustment comes amid an intense race in the AI sector, as global indices seek to increase exposure to hardware and cloud solution providers. Compared to sector peers, Astera Labs reported robust revenue growth exceeding 200% year-over-year in its most recent quarterly filing, while Rocket Lab’s inclusion strengthens the representation of the commercial space industry. Per market data, the inclusion of these companies mandates passive ETFs to rebalance their portfolios, potentially triggering substantial capital inflows into these specific equities.

At the close of June 11, 2026, ALAB stood at $367.47, while RKLB reached $114.78 and TER closed at $381.40. Investors should monitor liquidity levels as the June 22 implementation date approaches, as this date marks the peak of mandatory buying activity from passive funds. Markets are also looking ahead to upcoming Fed Barr speeches in the calendar, which could influence risk appetite for high-growth tech stocks.
