SpaceX faces a pivotal September 21 rebalancing event that could drive $15.5 billion in passive inflows, though looming share lock-up expirations present a significant supply-side risk to the stock.
Nasdaq-100 rebalancing expected to increase SpaceX's weighting, potentially adding $15.5 billion in passive inflows, but upcoming lock-up expirations may weigh on the stock.
SpaceX (SPCX) is set to receive an estimated $15.5 billion in passive inflows on September 21 as its weighting in the Nasdaq-100 index increases from 1.25% to 2.25%. While this rebalancing provides a technical tailwind, investors face potential volatility from upcoming lock-up expirations that could release over 2.3 billion shares into the market by November.
The rebalancing increases SpaceX's index weighting, which forces index-tracking funds to purchase more shares, potentially resulting in $15.5 billion of passive inflows.
The main risk is the expiration of lock-up periods for pre-IPO investors, which could lead to a large influx of shares hitting the market and potentially pressuring the stock price.
