Woofun AI reports that fund managers tracking the Nasdaq 100 Index executed a forced rebalancing on Tuesday, resulting in approximately $4.3 billion in passive purchases of SpaceX (SPCX) shares. Starting July 7, SpaceX officially became a constituent stock, marking the fastest entry into a major U.S. index in history. The inclusion leverages a rule change effective May 1, which lowered thresholds to allow "fast inclusion" after only 15 trading days if market value ranks in the top 40, coinciding with SpaceX's June 12 IPO. Critics describe the timeline as insufficient for price discovery and label it "the most shameless manipulation of a major index," noting that passive buying far exceeds the 3% to 5% public float.

Meanwhile, S&P 500 maintains its 12-month observation period and profitability requirements, delaying SpaceX's potential inclusion until mid-2027 due to projected losses. Analysts indicate the true test occurs on August 6, when Q1 earnings release and 20% insider share unlocks may trigger selling pressure.
