Pronóstico: Iran successfully targets shipping by 2026?

Active sub-markets

Market context

Iranian forces have already seized commercial shipping in the Strait of Hormuz, marking their first direct ship captures since the war began in February 2026, which frames the current 78% YES probability as a reflection of established escalation rather than speculative risk [7][8]. Historical precedents from April 2026 show Iran retaliating for US naval blockades by capturing two container ships and taking them to Iranian waters, explicitly claiming these actions as state operations rather than proxy attacks [7][8]. These events mirror the US seizure of the Iranian-flagged MV Touska, where US Marines disabled the vessel with gunfire and boarded it, demonstrating that kinetic strikes on commercial ships are now a standard tactic in this conflict [1][3].

Traders monitoring this Polymarket contract should watch for official announcements from the Islamic Republic of Iran confirming new seizures or kinetic strikes, as only actions explicitly claimed by Tehran or confirmed to originate from Iranian territory resolve the market [1]. Key catalysts include scheduled US naval blockade updates near the Strait of Hormuz and any Iranian naval patrols in the Gulf of Oman, where an oil tanker was recently seized [10]. Recent reports from Al Jazeera confirm that Iran labelled US actions as piracy following the capture of its tanker, suggesting further retaliatory seizures are likely if the blockade persists [1]. On-chain mechanics on Polygon using USDC conditional tokens will price these probabilities dynamically as new verified claims emerge, with the settlement window ending 2026-07-31T23:59:00Z.

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.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
