Strait of Hormuz traffic returns to normal by end of June?

Platform comparison

Market context

Shipping transit through the Strait of Hormuz remains constrained by regional tensions and Houthi attacks on vessels, with daily arrivals currently tracking well below the 60-call threshold required for market resolution. The 7-day moving average has fluctuated between 35 and 50 calls over recent months as insurers adjust coverage, some operators reroute via the Cape of Good Hope, and military escorts remain inconsistently deployed. No material change in attack frequency or geopolitical posture has emerged in the past 48 hours to suggest an imminent normalisation.

Historical precedent offers limited guidance: the 2022 Russia-Ukraine disruption saw Black Sea grain corridor transits recover within months once diplomatic channels opened, whilst the 2019 tanker attacks near Hormuz prompted a gradual return to baseline within weeks as naval presence increased. The current situation differs in that Houthi operations lack a clear off-ramp tied to specific negotiations, and regional actors have shown limited appetite for de-escalation. A 60-call average would represent roughly 30% above current levels—achievable only if attack incidents cease entirely and confidence in the corridor recovers swiftly.

Traders should monitor announcements from the International Maritime Organization regarding corridor safety assessments, any shifts in US or allied naval deployment schedules, and statements from major shipping insurers on premium adjustments. Reuters and Lloyd's List have reported sporadic attacks continuing into 2025; sustained periods without incidents would be the primary catalyst for the probability to shift materially. The 18-month settlement window provides time for diplomatic resolution, but the current 43% implied probability reflects genuine uncertainty about whether normalisation occurs by June 2026.

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.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram 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.
