Market context
Traffic through the Strait of Hormuz would need to recover to a 7-day average of 60 transit calls for a “Yes” result, and the market is pricing that as a 5% outsider. That makes the current view a strong favourite for “No”, with the value debate sitting on whether the lane can normalise fast enough after months of disruption. The relevant comparison is not a routine seasonal dip but a conflict-driven collapse in flow: USNI News reported on 1 May that Strait transits were below 10% of pre-conflict traffic, implying a very large jump would be needed before the end of May. In that context, the consensus looks anchored to the recent low run-rate rather than to a rapid snap-back.
The main catalysts are security conditions, carrier behaviour and any change in risk pricing for insurers and operators. A recent maritime-security update cited continuing military presence, intermittent VHF interference and reduced commercial traffic volumes, with elevated aerial threat and war-risk factors still in place. Those are the dependencies that matter for PortWatch readings: even if some sailings resume, the market needs a sustained lift in reported “Arrivals of Ships” across the 7-day window, not just a one-day bounce. Any de-escalation announcements, convoy arrangements, or evidence of insurers reopening cover more broadly would matter, but absent that, the favourite remains “No” and the contrarian case for “Yes” rests on an unusually fast and broad return of tanker and cargo movements.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
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
- 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.
- 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.
- Do I need to KYC for this market?
- Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.
