Why this matters:
This market estimates a 23% chance that Israel will conduct military action against Iran's Fordow nuclear facility by a specified deadline. The probability reflects ongoing regional tensions and Iran's nuclear program developments, balanced against diplomatic efforts and the significant military and geopolitical risks such action would entail. Factors pushing the probability higher include escalations in Israeli-Iranian proxy conflicts or breakthroughs in Iranian nuclear capabilities; factors pushing it lower include diplomatic negotiations or de-escalation agreements. The resolution hinges on observable Israeli military operations, international statements, and Iran's nuclear advancement trajectory during the contract period.

Key factors:
- Status of Iranian nuclear enrichment levels at Fordow as monitored by IAEA inspections and public reporting
- Frequency and intensity of Israeli military operations against Iranian positions in Syria, Lebanon, or Iraq during the contract period
- Statements from Israeli government officials regarding red lines for military intervention in Iran's nuclear program
- Activity in diplomatic channels between Iran, Israel, US, and European parties regarding nuclear negotiations
- Any Israeli or allied air defense system deployments or military posturing changes near Iranian airspace

Contracts:
- Will the US start the process of building a nuclear-powered data center on a military base before 2030?: Before 2030 — 51¢ Kalshi $90 (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.
