## Analysis

This market estimates a 13% chance that SpaceX will be added to the S&P 500 during the second quarter of 2026 (April-June). For a private company to join the index, it must first complete an initial public offering, as the S&P 500 only includes publicly traded U.S. companies. SpaceX would need to announce IPO plans, file with the SEC, and complete the offering all within the next two months for this to occur. The low probability reflects that SpaceX has shown no public indication of near-term IPO plans, and the company has historically prioritized operational growth over pursuing public markets. The primary catalyst would be an unexpected SpaceX IPO announcement; absent such a surprise, the probability hinges on whether market conditions and company leadership signal any shift toward public listing timelines.

### Key factors

- SpaceX has not filed an S-1 registration statement with the SEC as of May 2026, a required first step for any U.S. IPO
- The company would need to complete SEC review, roadshow, and pricing within Q2 2026—a compressed timeline compared to typical IPO processes
- SpaceX remains profitable and well-capitalized through private funding rounds, reducing financial pressure to go public
- Historical statements from Elon Musk have indicated SpaceX profitability and operational autonomy as reasons to remain private
- S&P 500 index inclusion requires companies to meet liquidity, size, and trading history requirements that must be satisfied post-IPO before inclusion consideration

## Methodology

Probability is **liquidity-weighted** across all bound Kalshi/Polymarket contracts: Σ(price × volume) ÷ Σ(volume). 30-day trajectory uses the daily mean of intraday 5-min captures. 24h delta = today's mean − yesterday's mean. Movement events are ≥3pp daily moves in the last 7 days.
