Strait of Hormuz traffic returns to normal by June 15?

Platform comparison

Market context

The Strait of Hormuz handles roughly one-third of global seaborne oil traffic, yet daily transit volumes have remained depressed since mid-2024. The market currently prices a 17% probability that average daily arrivals will recover to 60 or above by mid-June 2026—a threshold representing near-normal pre-disruption levels. On Polymarket, YES tokens trade at $0.17 per contract, with settlement conditional on IMF Portwatch publishing a 7-day moving average meeting that benchmark. The mechanics are straightforward: if the data appears before the June 15 deadline, the contract resolves immediately; otherwise, it settles NO at expiration.

Historical precedent suggests sustained shipping disruptions in this corridor take 18–24 months to normalise. The 2022 Russian invasion of Ukraine disrupted Black Sea grain exports for similar periods, whilst the 2019–2020 tanker war saw Hormuz transits fluctuate between 40–55 daily calls for extended stretches. Current geopolitical tensions in the Red Sea and broader Middle Eastern instability have compressed margins further, with insurers and operators pricing heightened risk into routing decisions. Recovery hinges on regional de-escalation rather than infrastructure constraints.

Traders should monitor announcements from the International Maritime Organization, shipping indices like the Baltic Exchange, and statements from major oil exporters regarding production and export intentions. Recent reporting from Lloyd's List indicates some operators are gradually returning to direct Hormuz routes as insurance premiums stabilise, though volatility remains. The probability of reaching 60 daily transits depends critically on whether geopolitical conditions permit sustained confidence among vessel operators—a variable largely outside shipping fundamentals.

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.
