$RKLB Rocket Lab surged more than 7% in premarket trading after Nasdaq announced the company will join the Nasdaq 100 as part of the quarterly index rebalance, effective June 22. The index inclusion catalyst arrives as the space sector attracts heightened investor attention ahead of SpaceX beginning public trading. Alongside Rocket Lab, Astera Labs, CoreWeave, Nebius, and Teradyne will also join the index, with each posting gains in premarket trading. The announcement reinforces growing institutional flows into the space and advanced technology sectors.

Joining the Nasdaq 100 is a significant milestone for Rocket Lab because the index serves as the benchmark for numerous ETFs and passive investment vehicles. Inclusion creates automatic demand from funds required to replicate the index composition, increasing institutional ownership and visibility. For a company that was viewed as a niche space operator only a year and a half ago, the move represents a notable level of recognition from the institutional investment community. The development further strengthens the narrative surrounding earnings momentum and long term growth opportunities across the commercial space industry.

Rocket Lab shares have climbed approximately 352% over the past 12 months, reflecting a major shift in market perception toward the space economy. What was once considered a speculative niche is increasingly viewed as a strategic growth infrastructure market encompassing satellites, communications, defense, and data services. The anticipated SpaceX listing has added further momentum to investor interest across the sector. However, the rapid appreciation also reflects increasingly elevated expectations embedded in current valuations.

The valuation gap has become a central discussion point. SpaceX was valued at roughly $1.8 trillion, implying a price-to-sales multiple near 35, while Rocket Lab currently trades around a forward sales multiple of approximately 60. That premium places Rocket Lab above a larger, more diversified, and more established competitor. While the company continues to benefit from multiple expansion and strong sector sentiment, the current valuation assumes sustained execution and continued growth.

Rocket Lab remains a relatively small company with meaningful dependence on successful launches and contract wins. Delays in launch schedules, weaker demand, or mission setbacks could have an outsized impact on investor sentiment and share performance. In addition, broader investor access to SpaceX may redirect capital flows toward the industry leader. These factors suggest that operational execution will become increasingly important as valuation expectations rise.
