5 clusters across 5 contracts.
These contracts were grouped by title similarity. The headline aggregate combines all clusters; verify the cluster you actually need before quoting a number.
Heads-up — heterogeneous clusters
The top two clusters share only 14% of their title tokens — “Will Reza Pahlavi visit Iran before Jan 1, 2027” vs “Who will be the next the head of state or government of Iran”. The headline aggregate weights both, so the number on this page is meaningful only if the clusters resolve to the same question.

Iran Regime Fall at 36%, Nuclear Deal at 50%: Divergent Middle East Scenarios
Prediction markets are pricing simultaneous 36% regime-collapse and 50% nuclear-deal odds for Iran, suggesting traders see extreme volatility and binary outcomes rather than gradual policy shifts.
Iran Uranium Enrichment Deal Odds Surge 20 Points
The probability that Iran agrees to end uranium enrichment by June 30 has jumped from 40¢ to 60¢, the largest single-day move in this contract. Trading volume is very high, suggesting a potential leak, official statement, or significant progress in talks.
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.
