Market context
Iranian naval forces have already seized two commercial cargo ships in the Strait of Hormuz, explicitly claiming the MSC Francesca and the Epaminondas were taken for inspection after alleged navigation tampering, while attacking a third vessel, the Euphoria, which now sits stranded near Iran’s coast[1][2]. These kinetic actions occurred the day after US President Donald Trump extended the ceasefire with Iran, yet the White House dismissed the seizures as not violating the agreement, arguing they did not breach the military terms[3][5]. The Islamic Revolutionary Guard Corps (IRGC) Navy confirmed the vessels are being escorted to Bandar Abbas, with crew members under Iranian control but reportedly treated well[2].
Historically, Tehran has leveraged control of the Hormuz waterway to escalate global economic pressure despite facing a US naval blockade and over 13,000 US military strikes on Iranian territory[4]. Recent data shows 308 vessels with Iranian ties passed through the strait between March and Sunday, averaging six daily, compared to only 90 non-linked ships averaging three daily, indicating Tehran’s persistent operational dominance[4]. This pattern of seizing commercial shipping while maintaining naval integrity suggests the current 78% market probability aligns with established IRGC behaviour rather than an anomaly[1][3].
Traders should monitor official IRGC announcements regarding further inspections or seizures, as well as US Navy responses to the ongoing stalemate, which could reignite conflict[1]. The Pentagon recently noted Iran’s navy remains intact and capable of boarding ships, contradicting earlier claims of obliteration, while Navy Secretary John Feeley’s immediate departure adds uncertainty to US command structures[5]. Any escalation in drone strikes by Iran against US warships, as previously reported in retaliation for US seizures, would serve as a critical catalyst for market resolution[7].
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
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
FAQ
- Is this market available outside the US?
- PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.
- 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.
