Market context
Ships are beginning to transit the Strait of Hormuz again following the initial U.S.-Iran ceasefire, yet full traffic levels remain severely depressed. Experts warn that while narrow corridors can clear within days, the entire strait requires weeks, possibly months, of gradual mine-sweeping to reopen safely. With only 11 days remaining until the July 15 settlement and current daily transits hovering near single digits, the mechanical hurdle of lifting a lagging seven-day moving average to 60 is exceptionally high.
Historical precedents and current market data frame the 17% crowd-implied probability as realistic rather than optimistic. Kalshi traders assign only a 57% chance of normalization by early August and 70% by September 1, reflecting deep scepticism about a swift return to pre-conflict schedules. S&P Global Market Intelligence recorded merely four transits on a recent Wednesday, and shipping giants like Hapag-Lloyd state that reinstating original schedules could take weeks, if not months, due to unresolved security conditions and stranded vessels at ports in India, Oman, and Pakistan.
Traders should monitor the next 48 hours of the ceasefire, which experts deem pivotal for owner confidence to re-enter the strait. Key catalysts include official announcements on mine-hunting progress, updates on AIS broadcasting normalization, and any sudden surges in daily crossings that might signal backlogged ships moving. While a rapid data reporting anomaly or unexpected rush of traffic keeps the possibility above zero, the sheer difficulty of raising a single-digit average to over 60 in under two weeks makes a "Yes" resolution highly improbable on the on-chain USDC/Polygon conditional tokens market.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
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?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- 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 Polymarket cost to trade?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
- 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.
