Market context
The Strait of Hormuz remains effectively closed, with commercial shipping suspended and daily transit calls hovering near zero instead of the normal sixty. This ongoing crisis, driven by the Iran war and US naval blockade, has halted roughly 20% of global oil and gas supply, forcing vessels to reroute via the Cape of Good Hope and tripling tanker spot rates for Gulf-to-Asia routes[2][3].
Historically, such near-standstills in critical chokepoints rarely resolve quickly without a definitive geopolitical shift; the current crowd-implied probability of 22% reflects this entrenched reality where traffic has been virtually shut for weeks[1][3]. Previous disruptions in the region, including mine-laying threats and GPS spoofing by sanctioned fleets, have consistently kept transit numbers below the threshold required for "normal" classification, making a return to sixty daily moving averages by mid-July an exceptionally low-probability event absent a ceasefire[3][6].
Traders must monitor President Trump’s explicit stipulation that reopening the strait is a prerequisite for any ceasefire with Tehran, as peace negotiations have shown minimal progress[3]. The immediate catalysts include any announcement regarding the removal of Iranian-laid mines or the granting of bilateral clearances for VLCCs, which have been absent for the entire last week[3][6]. Without a formal resolution to the conflict or a declared end to the naval blockade, IMF PortWatch data will likely continue showing averages well below the sixty-ship target, keeping the market heavily weighted toward a "No" resolution[8][9].
Methodology
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 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.
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.
- 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.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
- 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.
