Market context
President Trump announced a US blockade of the Strait of Hormuz on 12 April 2026, so this contract is really about whether Washington publicly reverses that position before 30 June. The current 17% implied probability points to a low but not negligible chance of an explicit lifting announcement within the window. That sits in the usual range for fast-moving geopolitical contracts, where prediction markets tend to price in either a diplomatic climbdown or a formal military de-escalation, while sportsbook-style lines often remain wider and less reactive unless there is a clear headline. In comparable Middle East escalation markets, the biggest moves have come not from battlefield developments but from official statements, joint communiqués, or a shift in US naval posture.
For traders, the main catalysts are any White House, Pentagon, or State Department language that moves from operational blockade to suspension, stand-down, or reopening. Recent reporting has suggested there is still no settled diplomatic path: Politico reported in April that Trump had floated several, at times contradictory, ways to reopen Hormuz, while a separate NBC News live update on the failed US-Iran peace talks described the blockade as having been announced after negotiations broke down. That means the key dependency is whether talks with Iran produce a public de-escalation framework, and whether any such deal is formalised before the settlement deadline. Absent a direct statement from Trump or a recognised US authority ending the blockade, the market is likely to stay anchored at a low single-digit-to-teens probability rather than converging quickly towards certainty.
Methodology
This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
