SpaceX is expected to see a significant increase in its weighting within the NASDAQ-100 index due to an upcoming quarterly rebalancing. This shift is driven by the expiration of shareholder lockup periods, which has increased the company’s free float.

Initial reports suggested the company’s free float could rise from under 10 percent to nearly 30 percent, potentially increasing its index weight to approximately 1.51 percent. Subsequent data indicated a more substantial rise, with preliminary estimates suggesting the weighting could climb from roughly 1.28 percent to approximately 2.82 percent.

Financial analysts anticipate that this reweighting will trigger massive inflows into the stock, with estimates suggesting billions of dollars in net purchases from index funds and exchange-traded funds (ETFs) tracking the benchmark.
