SpaceX SPCX Forces $4.3B in Nasdaq-100 Passive Buying Today — Low 3% Float Creates Historic Supply Crunch on Inclusion Eve

SpaceX joins the Nasdaq-100 before Tuesday's open, triggering an estimated $4.3 billion in forced ETF buying today — the largest single-stock passive-flow event since Nvidia's index surge. With only 3%–5% of shares in the public float and over $800 billion benchmarked to the index, QQQ and QQQM managers must absorb the position regardless of price. History shows NDX additions average a 1.13% loss on day one, warning momentum traders to watch lockup expiration on August 6.

Nasdaq-100 Adds CoreWeave, Astera Labs, Rocket Lab in First Rank-Based Rebalance — Drops Zscaler, Cognizant, Charter

The Nasdaq-100 added Astera Labs, CoreWeave, Nebius Group, Rocket Lab, and Teradyne while removing Charter Communications, Cognizant, Insmed, Verisk Analytics, and Zscaler, effective at today's open. It marks the first rebalance under Nasdaq's new rank-based quarterly methodology adopted in May 2026, tilting the index further toward AI infrastructure. The S&P 500 made a separate two-stock swap the same day, triggering forced buying and selling from index funds tracking roughly $800 billion in assets.
