Analysis

This probability estimates the likelihood of Iran experiencing a leadership change by a specified date. The 15% level reflects current market expectations that such a transition is possible but not imminent. Recent contract pricing suggests markets are pricing in elevated geopolitical risk between the US and Iran, with related uncertainties about uranium enrichment, territorial control, and diplomatic resolution. The main drivers are ongoing nuclear negotiations, regional military tensions, and the potential for diplomatic breakthroughs or escalations. Key upcoming events include reported timelines for peace deal discussions (May 15 and May 31) and statements on uranium enrichment progress, which would provide concrete signals about whether internal Iranian political pressure might intensify or reduce.

  • Related contracts show 38¢ pricing for June 30 peace deal prospects versus 5¢ for May 15, indicating market skepticism about near-term resolution
  • Uranium enrichment and Kharg Island control contracts trading at single-digit to low double-digit cents suggest low immediate probability of major escalation
  • Peace deal contract volumes exceed $289K daily, indicating active price discovery on US-Iran diplomatic outcomes that would directly affect leadership stability
  • The 15% baseline sits between lowest crisis scenarios (5¢ for May 15 peace) and moderate escalation scenarios (38¢ for June 30 peace), suggesting conditional probability on escalation trajectory
  • Absence of high-probability near-term leadership change contracts indicates markets do not expect imminent internal Iranian regime collapse from current conditions

Lateral coverage

Thin contract — here's where the deeper coverage is.

This page aggregates 2 contracts (31% headline). At low contract count, the price reflects two participants’ opinions, not a market consensus. The links below are heavier related questions where the orderbook signal is real.

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
