## Analysis

This market estimates a 3% probability that SpaceX's IPO closing valuation will fall between $1.0 trillion and $1.5 trillion. The low probability reflects skepticism that SpaceX could achieve this valuation range at IPO given current market comparables and recent private valuations, which have ranged between $180 billion and $210 billion as of 2024. The main drivers are SpaceX's revenue trajectory, profitability timeline, and investor appetite for space-sector companies at IPO. An actual IPO announcement with pricing details would be the primary catalyst to resolve this outcome. The outcome depends heavily on timing—valuations could shift substantially based on Starship development progress, government contracts awarded, and broader market conditions for growth stocks between now and any public offering.

### Key factors

- SpaceX's most recent private valuation (2024) was significantly below this $1.0T-$1.5T range, requiring 5-7x upside between current and IPO
- Successful Starship orbital test flights and demonstrated revenue from next-generation launch capabilities could support higher valuations
- No public IPO date has been announced; Elon Musk has signaled interest but emphasized focusing on core business operations first
- Space sector IPO comparables (e.g., Axiom Space, Rocket Lab) have generally priced well below $100B, limiting precedent for $1T+ valuation
- Time decay risk: this contract will only resolve if SpaceX completes an IPO by contract expiration, which requires an actual offering announcement and execution

## 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.
