Contract brief

This market will resolve to "Yes" if Iran publicly agrees to allow unrestricted commercial navigation of the Strait of Hormuz by May 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. Iran allowing unrestricted commercial navigation of the Strait of Hormuz refers to a public agreement by Iran that commercial vessels may transit the Strait of Hormuz without Iranian authorization/permission, payment of fees to Iran, or other Iran-imposed restrictions. A public agreement that all restrictions imposed on commercial vessels transiting the Strait of Hormuz by Iran as part of the US-Iran conflict which began on February 28, 2026, will be definitively lifted, without replacement by new restrictions, will qualify. A qualifying agreement must clearly indicate that Iran will not impose restrictions on commercial transit through the Strait of Hormuz. General statements about the strait being “open”, de-escalation, security, increased transit in the Strait, or stability in the region, which do not clearly indicate that Iran will allow unrestricted commercial transit through the Strait of Hormuz, will not qualify. An official pledge by Iran to allow unrestricted commercial navigation of the Strait of Hormuz will qualify for a “Yes” resolution whether as a unilateral announcement or part of an agreement with the U.S. or Israel. Any agreement or pledge made before the resolution date of this market will qualify, regardless of if/when the agreement goes into effect. An agreement by Iran to allow unrestricted commercial navigation of the Strait of Hormuz as a precondition of a more comprehensive peace process or deal will qualify, even if the agreement is not finalized or part of a formalized peace deal. The primary resolution sources for this market will be official information from the government of Iran and a consensus of credible reporting.

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.
