3% — SpaceX IPO Closing Market Cap: 1.0T-1.5T
Polymarket 3% · 1 contracts · $10K volume · medium confidence

Why this matters:
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

Contracts:
- SpaceX IPO Closing Market Cap: 1.0T-1.5T — 3¢ Polymarket $10K (weight 100%)

## 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.

## SF Signal

- SF Index, regime, and 30d Brier calibration are computed separately and surfaced at https://simplefunctions.dev/admin/calibration.
- No SimpleFunctions index / regime / calibration signal is bound to this topic yet — the headline above is market-derived only.
