Rocket Lab USA Inc. joined the Nasdaq-100 Index before the market opened on June 22, 2026. This inclusion ranks the company among the largest non-financial entities on the Nasdaq. Passive index-tracking funds and ETFs, such as the QQQ, must now purchase RKLB shares.
The stock recently faced volatility as investors rotated capital following the SpaceX IPO. Rocket Lab shares traded lower on the announcement day despite the index inclusion. Markets are now watching if mandated passive fund buying will provide future price support.
