Contract brief

This market will resolve to “Yes” if the United States agrees to Iran charging fees on ships transiting the Strait of Hormuz by May 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. Iran charging fees on ships transiting the Strait of Hormuz refers to U.S. acceptance of Iran imposing tolls, transit fees, passage charges, or other mandatory payments on commercial vessels in exchange for transit through the Strait of Hormuz. The United States will be considered to have agreed to Iran charging such fees if: - Donald Trump or another authorized representative of the Government of the United States publicly announces that the United States has definitively agreed to accept Iran charging such fees on ships transiting the Strait of Hormuz. - Iran charging such fees is included as part of a treaty or deal formally established between the United States and Iran, including through signing or other formal means. Agreement refers to an explicit acceptance, authorization, or consent to the specified action. Only announcements of definitive agreement will qualify. Suggestions, negotiations, expressions of openness, or other non-definitive statements will not qualify. Any definitive agreement or commitment made before the resolution date will qualify, regardless of when or whether the specified action is implemented. The primary resolution source for this market will be official statements from Donald Trump, the U.S. government, and their official representatives; however, a consensus of credible reporting may also be used to verify the details of an announcement or formal agreement.

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.
