Strait of Hormuz traffic returns to normal by July 31?

Platform comparison

Market context

Polymarket is pricing this at **1% YES**, which implies traders see almost no chance that IMF Portwatch will print a 7-day moving average of **60 or more ship arrivals** in the Strait of Hormuz before 31 July. On the platform, that outcome settles in **USDC** on **Polygon** through conditional tokens, so the only thing that matters is whether Portwatch’s published series reaches the threshold, not headlines about intent or diplomacy.

That low price sits against a recent sequence of violent swings in the corridor. Reuters reported on 9 July that oil tanker traffic was at a near standstill after renewed U.S. airstrikes on Iran, while CNBC said on 21 July that crossings had again slumped as shipowners avoided the strait amid fresh fighting and threats to maritime traffic.[3][2] By contrast, a Wall Street Journal report from early July said Kpler data showed traffic had already stabilised into a “new normal” of roughly 40 vessels a day, which is below this market’s 60-call line even before any renewed disruption.[1]

For traders, the key catalysts are not only military or diplomatic announcements but the shipping data cadence itself, because the contract can resolve as soon as Portwatch publishes a qualifying seven-day average. Watch for any ceasefire enforcement, naval escort changes, insurance guidance, or shipping schedule shifts that alter whether larger tankers and other vessel classes actually transit and are counted. The market is sensitive to a handful of missed or rerouted sailings: if traffic remains in the 30s or 40s, the threshold stays out of reach, but a sustained return towards pre-crisis levels would change the odds quickly.[1][2][3]

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.

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 Polymarket Alternative UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
