SpaceX began trading publicly in June 2026 but is excluded from Vanguard's S&P 500 ETF (VOO) because it doesn't meet key index requirements: at least 12 months of trading, profitability, and minimum 10% public float. SpaceX reported a $4.94 billion loss in 2025 and only 3-4% of shares are publicly available, disqualifying it until at least June 2027. VOO holders cannot gain exposure to SpaceX through the ETF until then, but can buy SpaceX shares directly or consider other funds with looser rules. The index committee maintains strict rules to protect investors and preserve index integrity, so SpaceX inclusion will be cautious and gradual when it happens.
