Market context
The Strait of Hormuz remains a critical chokepoint for global energy flows, with roughly one-fifth of the world's oil transiting through its narrow waters daily. Current traffic levels have been suppressed by regional tensions, including attacks on commercial vessels and military posturing between Iran and coalition forces. The market prices a 55% probability that seven-day average transit calls will recover to 60 or above by mid-July 2026—a threshold representing normalised pre-disruption volumes. On Polygon, traders are currently holding YES and NO conditional tokens at rough parity, with USDC liquidity concentrated around the 0.55 mark, suggesting genuine uncertainty about whether geopolitical conditions will stabilise within the settlement window.
Historical precedent offers limited comfort for bulls. The 2019 tanker attacks saw traffic disruptions persist for months despite international naval deployments. The 2022 Ukraine-related energy crisis prompted temporary rerouting but didn't fundamentally alter Hormuz transit patterns. Recovery typically requires either explicit de-escalation agreements or a shift in regional power dynamics—neither of which has materialised in the past eighteen months. The 2024 escalation cycle, including drone and missile exchanges, has kept underwriters cautious and shipping companies diversifying routes where feasible.
Traders should monitor announcements from the International Maritime Organization, shipping industry reports on rerouting costs, and any diplomatic developments from UN-brokered negotiations. Recent statements from regional actors suggest hardened positions rather than negotiation readiness. The settlement depends entirely on IMF Portwatch data publication, making the statistical threshold itself a dependency—historical gaps in reporting could delay resolution even if underlying traffic recovers.
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
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?
- Kalshi UK 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.
- 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, Kalshi UK triggers a quick verification flow that finishes in 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.
