Strait of Hormuz traffic returns to normal by July 15?

Platform comparison

Market context

The Strait of Hormuz remains effectively closed, with commercial transit near zero despite a brief reopening in mid-June that saw 25 vessels cross before Iran reversed the move following security incidents. This chokepoint, which normally handles roughly 60 ships daily and carries 20% of global oil, is currently blocked by Iranian military activity and potential mines, leaving over 150 vessels stranded and pushing war-risk insurance premiums to extreme levels. The crowd-implied 38% probability for normal traffic by July 15 reflects the fragile nature of the recent US-Iran memorandum, which guarantees immediate navigation but does not clarify Iran’s ultimate authority or the permanence of the toll-free window.

Historical precedents frame this low probability, as the strait was briefly reopened on 21 April 2026 before closing again the next day, demonstrating Tehran’s capacity to halt traffic instantly when geopolitical tensions flare. Traders must monitor the US naval blockade lift deadline of 19 July and Iran’s commitment to restore pre-war traffic levels within the same timeframe, alongside any announcements regarding mine clearance or new toll arrangements. Recent data from CNN confirms that while 25 commercial vessels traversed the strait on 18 June, marking the highest volume since April, the situation remains volatile with no resolution from peace negotiations, suggesting the 38% chance hinges entirely on the durability of the current US-Iran agreement rather than a sustained return to normalcy.

From a regulatory standpoint, this market’s accessibility is influenced by German GlüStV implications and US CFTC reach, particularly regarding the "no-KYC up to $1,500" threshold which allows retail traders to participate without identity verification under specific exemptions. However, the market resolves only if IMF Portwatch publishes a 7-day moving average of transit calls equal to or above 60, a metric that excludes unreported ships and remains contingent on the strait’s physical reopening. The current blockade and stranded fleet mean that achieving this threshold by mid-July is highly improbable unless the US-Iran memorandum is fully enforced and Iran maintains its "best efforts" to restore traffic without imposing new tolls or security restrictions.

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.
