SpaceX is preparing for a historic initial public offering targeting a $2 trillion valuation, prompting major index providers to adjust inclusion rules for the massive aerospace company.

Key Points

• SpaceX aims to raise between $50 billion and $75 billion, potentially becoming one of the world's most valuable companies upon its public debut.
• The company faces a "float problem," with a projected public float of only 2.86% to 3.75%, significantly lower than typical large-cap stocks like Microsoft or Nvidia.
• CRSP indexes may include SpaceX within five days of trading, while the Nasdaq 100 could add the company in 15 trading days under new "fast entry" rules.
• The S&P 500 is currently reviewing its inclusion criteria, which could potentially waive requirements for four quarters of positive GAAP earnings to accommodate the IPO.
• Index inclusion timelines vary significantly, with the Russell 1000 expected to add the stock in September and the S&P 500 potentially following in 2027.

Why it Matters

The rapid integration of SpaceX into major stock indexes will force passive investment funds to adjust their holdings, impacting millions of retail and institutional investors. Because different indexes use varying methodologies for float-adjusted weighting, investors may experience unexpected exposure levels and increased price volatility following the IPO.
