SpaceX and the S&P 500.
SpaceX is already in the Nasdaq-100. It can't join the S&P 500 before 12 June 2027, and it also has to turn a profit first.
S&P 500 checklist
- ✗12 months of trading since the IPO
First trade 12 Jun 2026, so 4 months so far. Earliest 12 Jun 2027. S&P reviewed this on 4 Jun 2026 and kept it, no fast track.
- ✓GAAP profit in the latest quarter
Q3 2026: net income of $4.40B ($4,404M, 8-K filed 20 Oct). Met for Q3. Next check: Q4 2026 results.
- ✗GAAP profit over the last 4 quarters added together
Last 4 quarters (Q4 2025 to Q3 2026): net loss of about $2.76B (-$2,347M - $4,276M - $541M + $4,404M). Turns positive if Q4 2026 net income tops ~$0.41B, when Q4 2025's $2.35B loss drops out.
