SPCX stock fell more than 2% to $151.50 despite positive developments around SpaceX, including NASA’s selection of Elon Musk’s space technology firm to launch the StarBurst satellite mission. NASA said on September 17 that the mission will fly on a Falcon 9 rocket no earlier than 2028 under its Venture-Class Acquisition of Dedicated and Rideshare launch services contract. The spacecraft will share the launch with other payloads, adding another government-backed mission and institutional customer to SpaceX’s launch pipeline. Near-term attention is also centered on SpaceX’s Nasdaq-100 weighting: Nasdaq added SPCX to the index in July, and pro forma data indicated its weighting could rise from about 1.28% to roughly 2.82% as more shares became available for public trading. Market estimates cited by commentator Sawyer Merritt put potential passive-fund purchases between $15.5 billion and $22 billion. Cathie Wood remains bullish on SpaceX’s long-term growth trajectory, while prediction-market bettors are watching for a possible Tesla-SpaceX merger announcement, although the odds remain very low. Such markets use smart contracts (self-executing blockchain agreements) to determine payouts based on real-world events.
