- SpaceX's IPO priced at $135/share, quickly rose to $225 then fell to ~$153, maintaining a ~$2 trillion valuation.
- SpaceX entered major indexes (CRSP, FTSE Russell, MSCI, Nasdaq-100) within days of listing, triggering passive buying in index funds.
- Index rules changed to allow companies with low public float (e.g., SpaceX's 4%) to be included, based on size rather than profitability.
- OpenAI and Anthropic are next in line for similar index inclusion due to their large valuations and low float structures.
- The S&P 500 declined to change its rules, keeping profitability and seasoning requirements, excluding SpaceX from S&P 500 funds.
- Index inclusion is phased and based on float-adjusted weight, making SpaceX's initial impact small in diversified portfolios.
- Direct investment in SpaceX involves restrictions and volatility, as seen in its post-IPO price swings.
- Broad index fund investors will automatically gain exposure to SpaceX, OpenAI, and Anthropic without direct stock picking.
