Market context

Donald Trump announced on 12 April that the United States would blockade the Strait of Hormuz, and the market now turns on whether that order is publicly and formally reversed before 30 June. The opening price of 17% YES implies traders see the blockade as politically and militarily sticky unless there is a clear diplomatic breakthrough or a change in US posture. That is a high bar, because an official lift would need an explicit statement from the president, the White House, the Pentagon or the US military, not just a pause in enforcement or looser patrol patterns.

Comparable episodes in Gulf crises suggest that once a blockade or naval restriction is announced, reversals usually follow negotiations, not quiet operational adjustments. Reuters reported that Trump recently told Pakistan’s army chief he could consider easing the naval pressure to help revive talks with Iran, while also noting that Iranian officials have rejected ultimatums and denied any intention to join fresh peace talks. That combination points to a narrow path: the US would likely need to judge that talks are advancing enough to justify a public step back, and Iran would need to avoid actions that make de-escalation politically harder in Washington.

For traders, the main catalysts are renewed US-Iran contact, any White House or Pentagon briefing on maritime rules, and the reported follow-up diplomacy involving Pakistan and potentially vice-president J.D. Vance. Reuters’ reporting suggests Pakistan is being used as a channel, but there is no sign yet of a deal that would force an announcement by the deadline. Absent a visible diplomatic breakthrough or a major change in regional security conditions, the probability of an explicit lift still looks limited.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
