Price history
18¢ current
+1¢Contract brief
This market will resolve to "Yes" if an official agreement over Iranian nuclear research and/or nuclear weapon development, defined as a publicly announced mutual agreement, is reached between the United States and Iran by May 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. If such an agreement is officially reached before the resolution date, this market will resolve to "Yes", regardless of if/when the agreement goes into effect. Agreements that include the United States and Iran as parties, even if they also involve other countries (e.g., a multilateral deal like the JCPOA), will qualify for resolution. The primary resolution source for this market will be an official announcement by the United States and/or the Islamic Republic of Iran, however an overwhelming consensus of credible reporting confirming an agreement has been reached will also qualify.

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.
