Market context
President Trump’s announcement on 13 July to reinstate the US naval blockade of Iran, effective 14 July at 4pm ET, has triggered immediate maritime restrictions across Iranian ports and coastal zones, with the US Navy warning neutral vessels to depart before enforcement begins[1][3]. The blockade, covering Iran’s entire coastline and oil terminals, permits humanitarian cargo only after inspection while intercepting any unauthorised vessel traffic regardless of flag[1][2]. This fresh escalation follows a brief ceasefire in late June and a prior blockade lifted on 18 June after a deal took effect, underscoring the volatility of US–Iran maritime policy[11][13].
Historically, US naval blockades on Iran have been short-lived and tied directly to ceasefire deals or diplomatic breakthroughs, as seen in the June 2026 lifting that coincided with a 60-day agreement on Hormuz transit[13][14]. The current 12% crowd-implied probability for an official end before August 2026 aligns with this pattern: past terminations occurred within days of negotiated accords, not through unilateral policy shifts. Traders should watch for any announcement from CENTCOM, the White House, or Trump’s Truth Social account signalling a suspension, lifting, or termination of the blockade, as these have been the sole triggers for prior resolutions[1][14].
Key catalysts include the 60-day countdown for final talks referenced in the June deal, any new ceasefire announcement, or shifts in US strikes on Iran, which have intensified over the past three evenings[11][13]. A resolution would require an explicit, public US government statement confirming the blockade’s end; silence or partial adjustments do not qualify[1]. With strikes ongoing and tensions high, the path to a YES outcome remains narrow unless a diplomatic breakthrough emerges swiftly.

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Today, 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.
