Market context
The Strait of Hormuz remains well below normal traffic, so the market starts with the underdog priced at only 1% YES and the consensus still leaning heavily against a quick return to 60-plus daily arrivals. Recent reporting put August transits around 9 to 13 vessels a day on five- and seven-day measures, versus roughly 73 a day as a pre-crisis reference in PortWatch-style tracking, leaving a wide gap to the threshold and making a normalisation by month-end look remote.[1][2]
That framing is consistent with the year’s comparable cases: traffic has repeatedly snapped lower after each security flare-up, then recovered only gradually, with Reuters reporting a near-standstill in early July, a two-month low later that month, and still only modest improvement in mid-August.[3][4][5] The value angle is therefore mostly on the no-side unless there is a genuine de-escalation and a rapid reopening of routing confidence; for yes holders, the only plausible edge is a sharp, sustained rebound in reported ship calls rather than marginal day-to-day noise.[3][5]
Traders should watch any ceasefire language, maritime security advisories, and coverage of ship attacks or blockade threats, because those have been the main catalysts for abrupt changes in transit counts.[3][4][6] Reuters also reported on 14 August that traffic had dipped again amid competing US-Iran claims and fresh incidents, underscoring how fragile the current flow remains and how quickly sentiment can worsen before the PortWatch average has time to catch up.[2][6]

Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
FAQ
- Where can I trade this market with the lowest fees?
- Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Who Will Win 2026. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- 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 Who Will Win 2026 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.
