Why this matters:
This probability represents the odds that SpaceX will not go public before the end of 2027. At 4%, markets are pricing an extremely low chance of no IPO occurring within the next ~20 months. The current assessment reflects strong consensus that an IPO is likely to happen before the 2028 deadline, driven by SpaceX's operational maturity, revenue generation from Starship development and Starlink, and Elon Musk's previous public interest in going public. The main factor that could shift this probability is any official SpaceX or regulatory announcement about IPO timing, delisting considerations, or material changes to the company's financial performance that might delay public markets entry. The key uncertainty resolution point would be any formal SEC filing or company statement regarding IPO plans for 2026-2027.

Key factors:
- SpaceX generated approximately $6.5B in revenue in 2024 and operates two revenue-producing divisions (Starlink and launch services) typical of IPO-ready companies
- Elon Musk has publicly discussed IPO plans multiple times, though no formal SEC filing has been made as of May 2026
- Market prices for higher valuation ranges ($1.5T-$2.0T, $2.2T+) trade at 33¢-43¢, suggesting belief in an IPO occurring but with significant valuation uncertainty
- No official SpaceX statement confirming or denying 2026-2027 IPO timeline has been widely reported, leaving the market to infer timing from operational readiness signals
- A formal S-1 filing with the SEC would be the primary catalyst to dramatically shift this probability, as it would indicate imminent public listing

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.
